Comparing Versions Of Sql
I'm taking up a new position and have never used sql before although use
and code in lots of other languages. When doing a bit of survey I find
many many versions of commercial and public versions of sql. Can anyone
tell me if the syntax is generally similar or are they completely
different. If I invest time learning mysql on XP or Linux will that be
useful if I end up using something like Oracle later on? The only one I
would avoid is MS.... like things that work occasionally.

Benchmarks Of Runtime Versions Of Mysql Or Other Sql Versions Sqlite Hsqldb
mysql vs sqlite vs hsql First of all i'm on a win32 platform using java. I also have mysql installed. My question isabout benchmarks and multiple inserts & selects SQLITE: http://www.sqlite.org/ HSQL: http://hsqldb.sourceforge.net I current have a mysql database of approx. 80mb. Each day I Insert approx .5mb of new records into this table, and I might also run mutiple Update, Delete, and Select queries as well. I'm trying to get an idea of how fast a sql database engine will run given that is is inside of the JVM. I know it's going to be slower than a db engine written in C and that's a trade off for being portable to different operating systems. What I want to know is how much of a trade off though - I don't want to have to wait 10 mins or deal with screen freezing... Right now on a windows platform using mysql things move really fast. Can anyone give me an idea of the time delay needed to do these Inserts in HSQL (ie: how much does the jvm slow things down).. Thanks in advance
Versions
I have MySQL 5.0.24 installed on a XP Pro SP2 PC. The latest version is 5.0.41. I looked at the change logs and they say they are bug fixes only. Have there been any security issues with 5.0.24 that I should be aware of? Do I need to move to 5.0.41 to be safe?
Run 2 Versions
Is it possible to run both MySQL 3.23 and MySQL 5, at the same time on the same machine with php4.3.0 and apache 1.3.27? What should I consider ?
Two Versions
I wanna run MySQL 3.23.54 and MySQL 5.0 in the same Redhat Linux 9 box at the same time. Is it possible?
Differences Between Versions
We have two versions of mySQL running; version 4.1.15 on a couple of local machines under Windows XP Professional and our public database running 3.23.58 under Apache. I was populating a new field in our members table based upon a match to a table called region using the following query UPDATE members,region set members.FPosition_Id = 19 where region.Region_Commodore_Id > 0 and region.Region_Commodore_Id = members.member_Id The query ran fine locally (ver 4) but gave a syntax error on version 3. Is there a list of differences/updates between these two versions? Does version 3 not support update queries using multiple tables? I tried parenthasizing the where statement but that made no change.
Versions Of AMP On Windows?
I am somewhat concerned that i have the right versions of AMP on my Win XP system so it will all work together... Is there some link that (in simple terms!) tells which versions are safe together? I currently have MySQL version 4.0.20d, with Apache 2.0.52 and php 4.3.10. Is this the best combination?
Two Versions On Same Machine
I had MySQL 4.2 - working fine. I saw version 5 is now stable so I downloaded and installed but did not run it (I think!). Carried on with 4.2. Then one day MySQLAdmin and Query would not log me on. I checked via the cmd line utility and when I typed in the password the window dissappeared! I opened MySQLAdmin again and reconfigured the log-on o 3307 (I remember this was default when I installed 5.0). OK, the server must be running. So keep with 5.0 as I managed to restore one of my schemas. I wanted a later version which is only in the 4.1 directories and copied it across BUT 5.0 does not see it. But when I go to stop and restart the 5.0 server in Admin as soon as I go to the server tab to do this it stops automatically! AND will not restart.
MySQL Versions
I am using MySQL 5 on my computer but the web-hotel I am contemplating to use only use MySQL 4.0xx. Can I use the database without modifying it? Or do I need to "convert" (downgrade) it for MySQL 4.0xx? If so, how do I do that?
Removing Old Versions
I loaded a new version of Mandrake Linux 10.0 CE and have also installed and dowloaded a new version of MySQL 4. I'm not sure but think I have several versions installed and running ... How can I check to see what is installed, what is currently running, and then perhaps remove them all and start by installing single new copy?
Compatibility Between Versions Of SQL
Hi! Would like to enquire if different versions of SQL are compatible to one another. I've done some code in PHP and which requires access to MySQL on my server. I have tested it on localhost and everything worked fine. Hence, i decided to upload both my code and the database i created to the server. That's when the prob started. I received this msg while trying to view my page: Could not connect to database: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111) what this is about? For info, my MySQL version on my personal computer is 5.0 while that of the server is 3.23. Are the database compatible?
How To Keep Trace Of The Versions From A Table
From the Code that is been written below i need to keep trace of the versions that are been read from the file(test1.lst) each time it is been changed.Does anyone know as to how i can store it in diff tables(version_0701151004 version0701151100,version_0701161000 ....versionYYMMDDHHMM) each time when this query is been called? n how to keep trace of the date and time ? or maybe is there any other method where i can store diff versions in diff files ? would be gratefull for any advice --DROP TABLE stocklist_values; CREATE TABLE stocklist_values( SAG_FREIGABE INT(1) NOT NULL, SAG_SNR VARCHAR(50) NOT NULL, SAG_NAME VARCHAR(40), GSM_RELEASE_VON VARCHAR(20)); LOAD DATA INFILE '/home/user945/database/test1.txt' INTO TABLE stocklist_values FIELDS TERMINATED BY '&'
XAMPP And MAMP Versions
I'm running an XAMPP version of mysql on a PC and the MAMP version on a Macintosh. I just realized that I needed to change a couple of tables. Can I change them on the MAMP version and then copy the appropriate files to the XAMPP version, and expect them to work? Which files should I copy over ... .MYI, .MYD or both? The MAC version is 5.0.19 The PC version is 5.0.27 I use Navicat to modify my tables on the mac and do not have this product for the pc.
Running Two MySQL Versions
Actually what I want to do is remove 4.1 because I downloaded 5.0 and installed w/o removing the previous version. I now have port 3307 for 5.0. Is this a problem and how can I change it back to 3306 so e.g. when I use Apache/PHP evrything works?
Two Versions Of Mysql On Same Unix Box
I have mysql 3.23.58 version running on my unix box. I installed a new application on it which need mysql version > 4.0 so I thought of having two mysql versions running on the same unix box. I have first installation in /usr/local/mysql and I untared the new version in /var/local/mysql-standard-4.1.18-pc-linux-gnu-i686-glibc23. I am following instructions given in http://dev.mysql.com/doc/refman/4.1/en/multiple-servers.html I also created a empty file and named it as mysql.sock.new and stored it in /var/local. When I try to start this new version from /var/local/mysql-standard-4.1.18-pc-linux-gnu-i686-glibc23 using ./bin/mysqld_safe --datadir=/var/local/mysql-standard-4.1.18-pc-linux-gnu-i686-glibc23/data & it says "A mysqld process already exists". Please tell me where I am going wrong and how to configure it properly?
Import Export With Different Versions
I am hosting a WP site locally on my computer, to test it before putting it online, Now I have the hosted WP site online & ready to go, but I am having trouble loading the backup data from my computer into it. When I go to import in the myPHP section, it gives me an error message of: Import failed, You probably tried to load too big a file. But the file is only 350kb! The max is 8Megs! Double checking, it looks like the 2 databases are different versions. Would this be the problem? If so, how do I go about downgrading the version on my computer? And once done, how would I transfer my posts & info onto it?
Row Select In Old Mysql Versions
We are using MySQL version 4.0.20-standard. Our application requires a query to do a row select. From what I have found this version does not support rownum. We are unable to update the version of MySQL. Can anyone give us some support.
Running Two MySQL Versions
It seems that my computer is running two different mysql versions. When I'm trying to login to the database it refuse my password and giving me access to the test configuration. This is what i get in the event viewer. Do you already have another mysqld server running on port: 3306 ? Event id 100. The problem occur when I changed my password for the database. I have turned off Mysql in local services but i think that that's the original version. When I start the xampp i think it starts the winmysqladmin version (not sure). How do I reconfigure the hole thing and how can I see what's running on my machine. I actually have another question to. I'm trying to run and open the shell mysqladmin which doesn't work. It's just a flash, which one of them am I supposed to run?? You have several options like mysqladmin, mysql, mysqld, mysqld-nt....etc. I opened the winmyslqadmin which i think wasn't that good.
Compatible Versions Of Software
MySQL, Apache and Php are a fairly common trio from what i gather .... but there can be alot of problems getting them to talk to each other.
Downgrade MySQL Versions
I need to move a MySQL database created with MySQL 4.1.22 on PHP 5.2.3 to a different server with MySQL 3.23.58 on PHP 4.3.8. Is it possible to convert the database to do this? Alternatively, is there a way to export from the newer version in a format that the older version will accept?
Windows And Linux Versions
I would like to know what are the main differences between windows and linux versions of this DB system. I´m using it on linux but i´m planning to migrate to windows... Is there any performance difference? Is it as solid as linux version? It´s of free use (under GPL) ? I made a test here in windows and it seems to work well..
Can Run Two Versions Of MySQL In Windows 2000?
I have been running 4.0.13 for several weeks now and though I'd like to = test 4.1.0. 4.0.13 is under c:MySQL. I downloaded 4.1.0 under c:4.1 = AlphaMySQL. When I try to launch mysql it brings me to the old = version, how do I access the new one without killing the old one? (I = have also tried putting 4.1.0 on a totally different machine and linking = to it also.)
Previous Versions Of MySQL With XAMMP
I've downloaded XAMPP for Linux 1.5.1 for use on Fedora Core 4. I notice it only has the latest version of MySQL on it. I'm working on two web sites (for different clients) and they are hosted on different shared Linux hosting servers (with PHP), each with different versions of MySQL available, i.e: MySQL 4.0.25-standard MySQL 3.23.52 Is it possible for me to use older versions of MySQL with XAMPP? Could I just turn off MySQL in XAMMP and just run and older version of MySQL independently of XAMMP? If I can then how would I install multiple versions of MySQL in Fedora Core 4?
Symlinking Between Different Serveurs And MySQL Versions
I have a hosted server where we have both web and intranet share a same database. For interne reasons we need to migrate the intranet onto one of our servers and keep the web on the hosted server. We will thus have the database splited in two. Our intern server willl have MySQL5 and our hosted one will remain with MySQL3.23.39 at list for a while longer. I would like your advises on the faisability of using symlinking to access the tables on the hosted server from our intern server, knowing that MySQL version are different. The tables on the hosted side are MyISAM. The main idea is to avoiding using replication to access comon tables on remote servers.
Utility To Convert Between MySQL Versions?
My webhost downgraded from mysql 5 to 4 and I'm seeing errors in the forum I was running. All I can see that would have changed and given me this database error would have been this downgrade. Is there a conversion utility availaible that can change back and forth between MySQL versions? I've looked around for about an hour thru Google and on this forum, but I haven't found anything yet. I was getting password errors, but we seem to have resolved that issue, and now I'm left with this database connection error. Thanks for any assistance! P.S. The errors I get are: Warning: mysql_error(): supplied argument is not a valid MySQL-Link resource in /home/clanloc/public_html/forum-old/db/mysql4.php on line 330 Warning: mysql_errno(): supplied argument is not a valid MySQL-Link resource in /home/clanloc/public_html/forum-old/db/mysql4.php on line 331 phpBB : Critical Error Could not connect to the database
Selecting Correct Versions Of MySQL
I have searched this forum and google to try and get a comprehensive answer to this question but i haven't found anything yet. I am looking to select the correct versions of MySQL, Apache and Php so that they all work together. I notice that there are alot of issues with various different versions sets being chosen and there seem to be instances where it can be very problematic if the wrong one is chosen. I am looking to use InnoDB and would like to use the latest versions of everything as possible but it doesn't really outline anywhere what works with what best. There are lots of cases that outline what can be problematic but i'm trying to avoid this if possible and find what isn't problematic.
Trouble With NATURAL JOIN Between MySQL Versions
I have this query which works perfectly well in MySQL 5, but doesn't work in 4.1. I know there were some changes made to join syntax between the versions but for the life of me I can't figure out exactly what I need to do to fix it: SELECT Status, UserName, FontName, FontPath FROM AccountInfo NATURAL JOIN AccountPrefs, Templates.Fonts WHERE AccountPrefs.HeaderFont = Fonts.FontID AND UserID = '$userID' works fine in v5, but in v4.1 I get the old "Column 'UserID' in where clause is ambiguous". I'm trying to match the UserID in AccountInfo and AccountPrefs, I just left the font thing in there as well because I'm not sure if it's contributing to the problem.
Alternative To Group_concat For Early Versions Of Mysql
Is there an alternative to group concat, if you are using a lower version of mysql. If any one has any ideas it would be great, currently my code (thanks to some one from these forums) looks like this. SELECT c.clientID, group_concat(ci.interestID) as interests FROM Clients AS c JOIN ClientInterests AS ci ON c.clientID = ci.clientID GROUP BY c.clientID HAVING find_in_set(1, interests) AND find_in_set(3, interests) Is there any way of doing this on a lower version of mysql? Is it possible to wirte a function similar to group_concat?
How To Detect If Different Mysql Versions Are Installed/runing
from my InnoSetup setup :) I need to detect if any version of mysql is runing on my windows. Others sugested to check fo a mutex or a Class Name(dont know what are these) or Windows Names or Look for a mysql*.exe, so is there something common for mysql starting with v3 .. v5? I mean what is the thing that i have to search for, to know at least if mysql is runing. For mysql v3 there are the posible runing files: mysqld.exe mysqld-max.exe mysqld-max-nt.exe mysqld-nt.exe mysqld-opt.exe or on Win98 only winmysqladmin.exe? For mysqlv4 .. im not sure yet For mysql 5 seems to be more simple, only mysqld-nt.exe Do I have to search for all these files(and others that I dont know yet :) ) to be sure that its not runing?
Comparing Age
So the birthdays in my MySQL table are in a column called DOB and in the format of say: March 8 1985. Now i have my own PHP function that will convert that to a nice numerical value of age relative to today, which is perfect. it is called getAge(). However, i can't seem to be able to parse an SQL query with that function inside...is there any way to parse my own PHP functions inside an SQL query?
Comparing
I'm currently working with two tables; A scheduling table and a document table. Basically I'm trying to make a query that says this -- "give me everything from this month and day in the Document table that's not in the Schedule"
Comparing A Csv To A Db Table
How would I go about comparing values in a CSV file to a table in the database, and then removing any rows where that value (an email address) matches? Is this something I can do in phpMySQL or will I need to create a separate PHP script or something? I maintain a mailing list using something called ListMessenger. It's a great web application, but the one major drawback is that it doesn't have a way to handle bounces. Over the course of 5-6 years, I'm now up to around 800-900 bounced emails every time I send out a newsletter. I'd really like to clean up the list and I was able to extract all the bounced address from my email client. I'm just not sure how to do it. I actually have an idea of what needs to be done... it's more the actual code to make it happen that I'm not sure of. I'm thinking it would be something like this: 1. Open csv file and read values into an array 2. Run a SQL statement that removes any rows from the "users" table if the "email_address" field matches any of the addresses in the array. Any help would be greatly appreciated. I can get into more specifics as far as the table/column names and stuff,
Comparing Tables
I have a query that produces a list of names of people who have completed a certain course. I want to be able to run a report which can show who has not completed this course. The code I have attached below just returns the same resut as those who have sat the course. SELECT distinct pps_principals.name as pname, pps_principals.login, pps_scos.name, pps_transcripts.score, pps_transcripts.max_score, pps_transcripts.status FROM (dbo.PPS_SCOS JOIN dbo.PPS_TRANSCRIPTS ON dbo.PPS_SCOS.SCO_ID = dbo.PPS_TRANSCRIPTS.SCO_ID) JOIN dbo.PPS_PRINCIPALS ON dbo.PPS_TRANSCRIPTS.PRINCIPAL_ID = dbo.PPS_PRINCIPALS.PRINCIPAL_ID where pps_transcripts.date_created between ��-12-01' and ��-12-31' AND PPS_TRANSCRIPTS.STATUS like '[PCF]' and pps_scos.name = 'COURSE1' or pps_scos.name = 'COURSE1.1' or pps_scos.name = 'COURSE1.2' AND PPS_TRANSCRIPTS.TICKET not like 'l-%' and pps_principals.name not in ( SELECT distinct pps_principals.name FROM (dbo.PPS_SCOS JOIN dbo.PPS_TRANSCRIPTS ON dbo.PPS_SCOS.SCO_ID = dbo.PPS_TRANSCRIPTS.SCO_ID) JOIN dbo.PPS_PRINCIPALS ON dbo.PPS_TRANSCRIPTS.PRINCIPAL_ID = dbo.PPS_PRINCIPALS.PRINCIPAL_ID where pps_transcripts.date_created between ��-12-01' and ��-12-31' AND PPS_TRANSCRIPTS.STATUS like '[PCF]' and pps_scos.name = 'COURSE1' or pps_scos.name = 'COURSE1.1' or pps_scos.name = 'COURSE1.2' ) AND PPS_TRANSCRIPTS.TICKET not like 'l-%'
Comparing Dates?
i have an 8 digit date string that i want to compare to a column of type 'date' in a MySQL db. the 8 digit string is in the format 'CCYYMMDD'. the question is: do i need to put it into the 'CCYY-MM-DD' format in order to get correct output from the datediff function, or can i simply leave it how it is?
Comparing Dates
I have a problem with me. I am describing the whole situation. I have a table, the structure of the table is as follows: Table Name: Announcement FieldName Data Type(Size) Announcement Varchar(50) St_Hr Decimal(10,0) St_Min Decimal(10,0) St_Day Decimal(10,0) St_Mon Decimal(10,0) St_Year Decimal(10,0) End_Hr Decimal(10,0) End_Min Decimal(10,0) End_Day Decimal(10,0) End_Mon Decimal(10,0) End_Year Decimal(10,0) The data stored is: Test Announcement,10,20,6,10,2005,11,0,8,10,2005 Now, I have to write a query to retrive announcements after filtering them as per the mentioned Starting and Ending Date & Time. The condition should use the local date and time.
Comparing Strings
I have a lot of records in a table named in this pattern "this text is the same.r01 someText (001/100)", "this text is the same.r01 someText (002/100)", "this text is the same.r02 someText (003/100)" etc. The idea is that i want to automate the process of recognizing the files belonging to the same file(.r02 in this case), and then set a value which shows that is belongs to a certain fileID in another table. The problem is that i have no idea what would be the best way to do this. My initial guess is that i would have to use a trigger and a LIKE clause comparing the "this text is the same.r02" part of the string, to see if it already exists in the database. If it does, i have to mark it as belonging to the same file. I guess using a LIKE clause would be very slow, and the amount of records will grow quite big(millions of rows).
Comparing Tables
tablename: leftfile Fieldname: leftword Data: bbb ccc xxx zzz Tablename: rightfile Fieldname: rightword Data aaa bbb ccc ddd eee I want to know which records in table rightfile do not match records in leftfile. My assumption was that this should be possible with: select rightword from rightfile, leftfile where rightword not like leftword. The opposite query, which is finding a match between records works spot on: select rightword from rightfile,leftfile where rightword = leftword. Two questions: 1. What would be the proper method of achieving the desired result (all records from rightfile that do not have an equal record in leftfile) 2. I must be missing something important in my thinking. Why would my method not work?
Comparing Two Fields With LIKE
Here's the sql: SELECT * FROM boxer.lpars a, boxer.libraries b WHERE b.lpars LIKE '%a.lpar%' AND a.deleted = 0 ORDER BY node, lpar b.lpars will commonly look like: "WIN1#WIN2#WIN3#WIN4#" a.lpar will commonly look like: "WIN1" When I run this query I get zero matches. What do I need to do to match fields using LIKE?
Comparing Two Table
I have two tables: CREATE TABLE `FootballerScore` ( `footballerID` mediumint(4) NOT NULL default '0', `GameWeekID` mediumint(4) NOT NULL default '0', `GameRuleID` mediumint(4) NOT NULL default '0', `Goals` mediumint(4) NOT NULL default '0', `Assists` mediumint(4) NOT NULL default '0', `CleanSheets` mediumint(4) NOT NULL default '0', `YellCards` mediumint(4) NOT NULL default '0', `RedCards` mediumint(4) NOT NULL default '0', `WeeklyScore` mediumint(4) NOT NULL default '0', `AccScore` mediumint(6) NOT NULL default '0', PRIMARY KEY (`footballerID`,`GameWeekID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; CREATE TABLE `footballers` ( `footballerID` mediumint(15) NOT NULL default '0', `fname` varchar(15) collate latin1_general_ci NOT NULL default '', `sname` varchar(15) collate latin1_general_ci NOT NULL default '', `value` decimal(15,1) NOT NULL default '0.0', `PremTeamID` mediumint(15) NOT NULL default '0', `position` varchar(15) collate latin1_general_ci NOT NULL default '', `Importance` varchar(4) collate latin1_general_ci NOT NULL default '', PRIMARY KEY (`footballerID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci; The footballers table basically has a list of all the players in the premiership and the footballerscore table has a list of the player who played in a given week. For any one week I need to find out who DIDNT play. I can do this by comparing all the footballerIDs in both tables and the difference is the group I need. However I'm not sure how to put this into an SQL statement.
Comparing Tables
Let me set the scene for you. I have two tables on the same database: hr_harassment (everybody who has already entered into a training class) fields: lname, fname, class hr_employee_list (everybody who needs to enter into a training class) fields: Lname, Fname I need to compare the two tables to figure out who has not yet signed up for the class. What would be the easiest way to do this? I am using PHP to program the page. I looked online and came up with this: SELECT * FROM hr_employee_list AND NOT EXISTS (SELECT * FROM hr_harrassment AND hr_employee_list.Lname = hr_harrassment.lname AND hr_employee_list.Fname = hr_harrassment.fname) But my browser tells me this: Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in monitor.php on line 270
Comparing Two Sub_queries
I need to return the rows that are NOT duplicated. I am trying to be sure information on one db is the same on another db. I just need the odd rows returned. Is there an opposite of the union function? EX> Query 1 returns acct_num product_id count 1507692 100000500 1 1846486 106 3 1846486 100000500 1 Query 2 returns the same. I want the row returned if they aren't the same.
Data Comparing
i'm writting a program that uses my sql to compare a date time feild to a date that i have to count call on one date the statment looks like this: SELECT Count(*) FROM wab_answers WHERE wabScreen=1 And DateDiff(answerTime,'" & curDate & "')=0; where curDate is string containing the date that i would like to compare. I'm not to sure on the correct way to do this. Just need a push in the right direction.
Comparing 2 Tables
I have a table of users which is updated once a week by the client sending me a spreadsheet, and me uploading the CSV to my scripts which then import the data into the user table. This all works fine. However instead of sending me incremental data that can be just imported, the client has now taken to sending me a complete data list. The problem with this is that I cannot just empty the user table and re-populate with the new data as I will lose the primary key values which I use elsewhere. My solution to this was to create a new table for importing with the same structure as my user table, import the csv to there, then somehow compare the tables and add the rows missing from the import table into the user table.
Comparing Times
I'm creating a voting system, and want to prevent people from cheating. Therefore I'm logging their IP, and the time they voted, and what I'm planning to do is have a script which will delete any records which have been in the database for say 24 hours. To get the length of time I was gonne use: HOUR(TIMEDIFF(NOW(),time))
Comparing Dates
I have a releaselist. All data before today should be deleted. How do I do this? DELETE * FROM releaselijst WHERE Release < CURDATE() doesnt work
Comparing Two Tables
I have to compare two tables. They are both of more than 650.000 rows, and I have to find which ones are missing in one of them. I have tried to first find all the rows in table A, and then search through table B to see if you can find it there. But this takes way to long time. Too bad mysql4 does not take subqueries. Does anyone out there have a good idea to get this done?
Comparing Two Tables
I was wondering if there was a SQL command I could use that would find similar values from two specific columns in two different tables.. possibly an intersect? heres what I mean Table 1 blogTitle="I love soccer" Table 2 articleTitle="Soccer is fun" Is there a SQL command that would be able to find the similarities between each column in each different table if, lets say, the user entered "soccer" as a query?
