MYSQL :: "Illegal Mix Of Collations" MySQL Error

Single Query For No Of Hits "Today", "This Month", "This Year"
Is it possible to construct a single query that fetches the no of pageviews "today", "this month", "this year" and "total since start"?

The table is very simple, one field for Date (YYYY-MM-DD) and one for the no of pageviews this day.

If not, would it be much slower/faster to divide the query into 4 different queries?

REQ: MySQL 4.0 Equivilent Of "DateDiff("m", Date, Now())=1"
I have a query that works in the rest of the SQL world

"SELECT invoice.*, invoice.Date
FROM invoice
WHERE (DateDiff("m", Date, Now())=1);"

which will give me all of last month's invoices.

However it doesn't work with MySQL 4.0.

While

"SELECT
Invoice.*
FROM
invoice
WHERE
(Month(Invoice.Date) = ((Month(Now()))-1))"

Is a close substituent, it will blowup in January.

Anyone have an equivalent expression for MySQL 4.0?

Maximum Execution Time Of 300 Seconds Exceeded (was "MYSQL Error")
I have a huge database 400mb+ in size which i have exported into a .sql file. I tried to run this export script into a new database and it runs fine until three quarters into the scripts execution and the following error appears:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<br / >
<b>Fatal error</b>: Maximum execution time of 300 seconds exceeded in <b' at li ne 1
I believe this error may relate to "delayed_insert_timeout = 300". How do I increase this limit in mysql - maybe it may solve the problem but then again it may not .

Any advice is most gratefully appreciated - As you can imagine if the script runs fine for 3/4 of it and then an error appears, stating the error is on line 1, it will take me days to go through the whole script (hundreds of thousands of rows) to find the error as I assume the error does not reside on line 1 as this line would have been executed.

I am running the script on mysql 5, and via source /path/****.sql on linux.

Encountering 2013 Error ("Lost Connection To MySQL Server...")
I have a nightly job that performs backups on my MySQL servers. There are three production MySQL instances on different machines. My backups have been running successfully for months (until now).

However, on last night's backups for one instance, a couple of database/schemas (appear to have) backed up successfully, but the larger schemas failed, as follows:

=======================================
Backup of schema dhunt was successful in 0 seconds
Backup of schema mysql was successful in 0 seconds
Backup of schema support_appl was successful in 0 seconds
Error: Backup of schema support_dict was not successful (1115 seconds):
mysqldump: Got error: 2013: Lost connection to MySQL server during query when retrieving data from server
Error: Backup of schema test was not successful (0 seconds):
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) when trying to connect
=======================================

I re-ran the backup cron job with the same results. Does anyone have any troubleshooting suggestions?

Getting Dreamweaver 8 To Work With MySQL: The "Unidentified Error"
I set up MySQL on my Macintosh at my job (G4 / OSX 10.3.9) 3 days ago, along with PHP --

all went fine, & I got MySQL started, a DB set up -- until I tried to connect Dreamweaver to it I go to connect to the DB in Dreamweaver 8, and when I try to set up the DB in the "databases" tab and click on the "database" field I get :

"An unidentified error has occurred" Code:

Bugzilla: MySQL Returns "Got Error 127..."
Our bugzilla database started giving this error during last week sometime. "Got error 127 from table handle". I Googled it, and came to believe that "repairing" and "optimizing" the table should sort out my problem, only to be shocked to see that over 10 000 records have been deleted by the repair/optimise. You see, this is not an option. We have over 18 000 bugs logged on our system, and as an organising our size, we need to comply to certain SAS70 requirements. Losing 10 000 records on our bugs database will fail the entire organisation the SAS70 reward, and guess what... it's on my plate, and if I can't do anything about it... people will talk bad about me for long after I've left the company.

I understand that the table records has gone corrupt. How it went corrupt I don't know and why it was working fine with over 10 000 corrputed records for the last 2 years, I also don't know. But right now it's not my job to understand it... I need to fix it, and keep every record in tact.

I've done a restore of the data all the way back to the day just before it crashed. When I ran a repair and optimize then, it did the same thing... over 10 000 records dissapear. PLEASE HELP. I am despirate!

"ERROR 1064 (42000): You Have An Error In Your SQL Syntax " When Trying To Import Backup
Just upgraded to the latest version of mySQL. Before I did that, I did a full backup of all tables using the Administrator tool. Now when I try to do a restore, I get the message in the subject.

Searching For Numbers - "close To" Or "approximate"
I would like to know how to search a table for records where a particular field is "close to" a particular number.

For instance, let's say I have a table containing students and their most recent test scores. I'd like to see students who scored 7/10. That's easy enough (select * from table where score = 7). I'd also like to run another query to identify other students whose scores are not 7 but "close to" 7. Ie students who scored 6 or 8.

As an added bonus, I'd like to be able to do a related search that shows students who scored 7, then shows the other students ordered by how "close" they are to 7. Ie students who scored 6 or 8 are "closest" matches, and students who scored 1 are "furthest". I hope this makes sense!

Is there any pre-existing MySQL command that will do this? Or will I have to run separate queries for each value?

ERROR 1206 (HY000) At Line 41: "The Total Number Of Locks Exceeds The Lock Table Size"
I'm loading a large file into a table, and I get this error:

"ERROR 1206 (HY000) at line 41: The total number of locks exceeds the lock table size"

I already searched, and the only advice given was to do an explict full-table lock on that table before loading to avoid the row-by-row locks filling up the lock table. Well, I tried that, and it's not helping either.

Too Many Tables Error (was "I Feel Like I Am Missing Something")
I am new to administrating servers, and I just got myself a dedicated server and I am trying to do some things...

Right now I wanted to make a backup of a mysql db but I get an err 24 because I the db has too many tables (over 16000).

I want to edit the open_files_limit so I can get past this error, but I dont know where to edit!

All the places I read say I should edit my.cnf, so I use vi /etc/my.cnf and I get this:

[mysqld]
set-variable=local-infile=0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

[mysql.server]
user=mysql
basedir=/var/lib

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
After searching around this doesnt look right because all other files I've seen have way way more info in them.

Did I miss a configuration step somewhere, or am I editing the wrong file?

I am running Fedora Core6 with plesk.

Subquery Gives Syntax Error (was "A Sql Problem")
i am in deep trouble while executing this query on the server having mysql version " MySQL - 4.0.25-standard"

The query is :- Select * from table1 where column1 IN ( "Select DISTINCT column2 from table2") ORDER BY column1 DESC limit 0,20
it gives no results , i have seen that both tables have records corresponding to them.

i have tried to eliminate quotes from the subqurey then it gives an syntax error

while it is working at my localhost. having mysql 5.0.27-community-nt

The query here runs as Select * from table1 where column1 IN ( Select DISTINCT column2 from table2) ORDER BY column1 DESC limit 0,20

if i put quotes here then it gives no results.

Error : "cannot Be Part Of FULLTEXT Index"
in order to make it possible to do a fulltext search on multiple columns I created a temporary table which holds all the fields I want to search in from different tables. I'm creating a temporary table, create an fullindex on it, search in it, drop it. On our local server this works fine. But when I perform the code on the server of our client I get the following error message:

"Column 'manufacturertitle' cannot be part of FULLTEXT index"

This is caused by:

"CREATE FULLTEXT INDEX full_index ON SearchTemp(producttitle, description, description2, manufacturertitle );"

In the original table the field 'manufacturertitle' has the following properties:
Type: varchar(255)
Collation : utf8_general_ci
Null : Yes

I found the following solution somewhere but I have no to clue what to do now:
"As of MySQL 4.1.1, full-text searches can be used with most multi-byte character sets. The exception is that for Unicode, the utf8 character set can be used, but not the ucs2 character set.".

Value "000" Stored As "0" In Text Field?
I've managed to import my data from a CSV using SQLyog Enterprise, however, I have a problem with the table storing the text value "000", MySQL truncates it to "0", unfortunately, I need the value to be stored as "000", does anyone know of any way that I can force the field to store all the characters, rather than treating it as a number? Surely a text field should treat any numbers stored within it as text?

Return A "true" Or "false"
i wanna do a "select", where if the script finds any matches, i dont wanna know about them. Instead, i just want it to return a a value: true (1) ou false (0).

ie.:

$sth = $dbh->prepare("SELECT * FROM maps WHERE name='algo' LIMIT 1");
$sth->execute();

if (match is true) {
print "True Match. A match was found";
}
else {
print "False Match. No matches were found.";
}

"Group By" Forgets "Order By"
I'm trying to build a simple RSS reader for a client and am running into some serious problems with the GROUP BY in MySQL. Basically I have two tables: one that holds all the entries and one that holds all the feeds. Then what I can do is say:
[MYSQL]SELECT * FROM entries WHERE feed_id='13' ORDER BY date DESC[/MYSQL]
That will select all the entries that belong to feed #13. This is fine, but what I'm doing now is building a library that will display the feed_id with the latest entry with that id. So I would think it would be something like the following:
[MYSQL]SELECT * FROM entries GROUP BY feed_id ORDER BY date DESC[/MYSQL]
That should get me the single latest entry from each feed_id. However it's forgetting the ORDER BY clause all together and seemingly ordering it by the auto-incrememnt value in the entries field.
