Invalid Use Of Group Function
I have the following Sql Statement... I'd like to find the sum of hrs worked by an employee in the month, the required number of hrs, and the sum of the difference between the two, the worked hrs are calculated by subtracting the max vtranstime - min vtranstime and the required hrs are calculated by subtracting max to1 - max from1....
I tried to do the following:
select sum(timediff(max(vTransTime),min(vTransTime))) as worked,
sum(timediff(max(translog.to1),min(translog.from1))) as required,
sum(timediff(sum(timediff(max(vTransTime),min(vTransTime))),
sum(timediff(max(translog.to1),min(translog.from1))))) as overtime,
empid,deptname, firstname,lastname from employee,translog,department where
employee.emp_magnetic_num=translog.vId
group by employee.empid
I am getting the following error :

Invalid Use Of Group Function - Max(`mainid`)+1
I am trying to insert a incremented number into the menu table. I will have an autoincremented number as well as the mainid number. When I tested the code that is below, the above error happened. Can someone please tell me the correct way of doing this? I am getting really frustrated with this. Nothing wants to work for me. require "config.php"; $insert06 = "INSERT INTO `menu` (`mainid`) VALUES (max(`mainid`)+1)"; // error line if (mysql_query ($insert06)) { print "Mainid added."; $query2 = mysql_query("SELECT mainid FROM menu") or die ("Could not query because: ".mysql_error()); while($row2 = mysql_fetch_array($query2)) { echo $row2['mainid']." = Mainid"; } } else { print "<p>Could not add the entry because: <b>" . mysql_error() .

Group By Returns Invalid Dates
Hi i have one table: ID, User, Score, Date 1, mac, 1234, 2007-12-09 09:01:07 2,kurca, 3232, 2007-12-05 09:43:57 3, mac, 999999, 2007-11-07 09:44:14 I wan to create a high score list which will represent the best scores but not repeating anyone for example: 1, mac, 999999, 2007-11-07 09:44:14 2,kurca, 3232, 2007-12-05 09:43:57 Now i use: SELECT ID, User,MAX(Score) as maxScore,Date FROM `table` GROUP BY User ORDER BY maxScore DESC with this query the score is right but the date is invalid example: 1, mac, 999999,2007-12-09 09:01:07 2,kurca, 3232, 2007-12-05 09:43:57
IF Function,GROUP BY,aggregate Function Problems
Yep, I have all those problems in the title. So I'll explain each one at a time - I did have another thread relating to this very same query but I thought it was time to update where I am with the query because at the moment I feel like I am getting nowhere! The query I have basically searches through an items_ordered table through each product and checks to see whether the item is VATable or not. This is not where I have the problem though. Where I am really having the first problem is when I am trying to use the IF function to check if the TOTAL of an order is over £300. IF it is then I multiply it my 0.95 (i.e. 5% off). With the query below I get no errors but neither do I get the desired result. It's as though it couldn't even see it. =....
Group Function
I have a table with the below model. SN Parent Child amount 1 A01 A02 1000 2 A01 A03 1000 3 A02 A04 500 4 A03 (null) 1000 5 A04 (null) 200 5 A05 (null) 1500 How can I write the query to capture the sum of amount on A01 and A05 Parent Sum of amount A01 3700 A05 1500 Where 3700 is sum of 1000(A01-A02), 1000(A01-A03), 500(A02-A04), 1000(A03-null), 200(A04-null)
Group Function
Why can't I use a group function when I update? UPDATE table1, table2 SET table1.activity_count = count(table2.activity_id) WHERE table1.user_id = table2.user_id GROUP BY table1.user_id I get an "Invalid use of group function" error. I've tried this kind of thing in several queries & got the same error, so it's not a problem with this particular query. Is there any way to get around this without getting the results and using a loop to insert?

GROUP BY Function And Getting Rid Of NULL Results
Ok, here is a query I'm doing: SELECT site , sum(uniques ), sum(trials +full_price ), round(sum(uniques)/sum(trials +full_price )) as ratio FROM mpa3_all_stats WHERE date BETWEEN '2005-12-01' AND '2005-12-15' GROUP BY site What I want to do is get rid of the null results that I'm getting from this return. As if I order by the last field, the nulls will go to the top if it's ASC. Which I need to do a ASC order on the last column. But I can't figure out a while to get rid of the null results. I've searched everything I could think it would be under. Here is partial data I'm getting: Code: +------+----------------+----------------------------+------------------------------------------------------+ | site | sum( uniques ) | sum( trials + full_price ) | round( sum( uniques ) / sum( trials + full_price ) ) | +------+----------------+----------------------------+------------------------------------------------------+ | 18 | 99865 | 119 | 839 | | 19 | 121386 | 188 | 646 | | 20 | 479 | 0 | NULL | | 21 | 1314 | 0 | NULL | | 22 | 100541 | 226 | 445 | | 33 | 21457 | 169 | 127 | +------+----------------+----------------------------+------------------------------------------------------+

Invalid Use
I have tested my query on MySQL 5 and it works, sadly the server it is to be run on only has 3. I was just wondering what I need to update in the following query to get it working on 3 or if it is even possible to get it running on 3. Code: ..... and keyword IN ('keywords') group by people having count(*) >= 1 ORDER BY people ASC
Invalid Index
I try to used the MyPhpAdmin 2.8.2.4 with PHP 4.4.4, MySQL5.0.2.4 and Apcache2 and I got this error, 'invalid Index'
Directory Name Invalid
For testing purposes I have PHP installed and I have MySQL installed on my local laptop. Windows XP Pro I am just learning both of them. I have read quite a few chapters in the MySQL Manual. Enough to allow me to get around in MySQL and directly create tables an view information in them, upload .txt files into the tables, etc etc. I am receiving an error when I try to connect to MySQL via a PHP script. I have no problem connecting to MySQL via Command Line. The error I receive is "The directory name is invalid." Here is my code... I am not sure where to put the directory name or where to put the directory path in order to make it valid. I am not sure what directory it is talking about. <html> <head><title>Connect to MySQL</title></head> <body> <?php //connecting to the mysql server uses a mysql_connect command. $link = mysql_connect("locoalhost",$_POST['username'],$_POST['password']) or die("Connect Error: ", . mysql_error()); echo 'Successfully Connected. '; mysql_close($link); ?> </body> </html> Where exactly would I put the path to the directory or where would I name the directory?

Check the manual that corresponds to your MySQL server version for the right syntax to use near 'OLD_PASSWORD ('newpwd')' at line 2

Invalid Argument While Using BCP (Script)
This will be a 50/50 question. It's either something that the SQL experts can answer or a scripting forum. I'm new to SQL and just coming to grips with getting familiar with scripts. I've developed a small script for my workplace that will connect to a remote server and extract the specified table that I want, zip it up and then copy it back to my local machine. This works fine until it tries to run the bcp command. If I tivoli to the remote machine and type the bcp command in command prompt it works fine. However when executed from the script it throws an invalid argument and seems to refer to the "-" minus I place in front of the U (user) or P(pwd). The script echos the users table request to a file which is then copied to the remote server (SQLtable.cmd) and then PSEXEC is called to connect to the server and run the script. e.g. psexec \%Server% -u %user% -p %password% "C: empSQLtable.cmd" PSEXEC then returns the following error. C:WINNTSYSTEM32>Bcp FrontOff..SHIFT_TER_DATA out C: empdmpnlSHIFT_TER_DATA.dat ûUsa ûPpwd (chopped off the -n) Unknown argument '¹Usa' on command line. Sorry about all the data, just hope someone can help. Must be an easy way. The small script which psexec is executing contains two simple lines. Bcp FrontOff..SHIFT_TER_DATA out C: empdmpnlSHIFT_TER_DATA.dat -Usa -Ppwd -n wwzip -9 C: emp\%username%SQLtables.zip C: emp\%username%*.*
Invalid Characters With PHP And MySQL
I am writing about a situation that our client is currently experiencing with Linux Mandrake, Apache, MySQL and PHP. We successfully deployed a website running on this type of system for a period close to two years. It has a HTML GUI component that the client can type or paste content into and it serves-up dynamic pages in PHP from a MySQL database. Recently the web site was hacked by the Travel Bug virus and it forced the client to restore the web site and server software mentioned below. Original Install Mandrake 8, MySQL 3.23.32, PHP 4.0.06 and Apache 1.3.26-x.x Current Install Mandrake 9.0, MySQL 3.23.52-1, PHP 4.2.3-1.1 and Apache 1.3.26-6.1 The current install has lead to new problems. Content with double and single quotes are showing up as squares or question marks. For example, I have a page that is showing the square symbol in place of double quotes. If I do a view source on that specific page I can see the double quotes but if I telnet into the server and query the MySQL record belonging to that page the square or double quote character is nowhere to found. The following items are the steps we tried to understand why this is happening. First, we did the following to test the integrity of the MySQL backup file. We Restored the MySQL database on our test environment which has the original software specs mentioned above but on a window server running IIS not apache. I did a restore of the MySQL database file and did not get any invalid characters. Even though the environment isn’t completely identical to the clients we can make the assumption that the dump file wasn’t corrupted. Second, possibly content editors were copying and pasting from word into the HTML GUI component thus creating these invalid characters. In most cases yes but I personally noticed the invalid character issue with a page that doesn’t use the HTML GUI component. Third, Possibly the configuration especially the character set from the original version to the current version of MySQL is not configured correctly. We believe this to be the primary issue. The resolution is to configure or reinstall MySQL and restore from backup. Fourth, has anyone tried the PHP functions to convert the invalid characters. A request was to look into the iconv() function. The iconv library functions convert strings between various character sets encodings. This involves compiling the PHP interpreter which is why I haven’t tested it. Fifth, Can some other process running on the server be causing this? Altogether, we soon will begin creating a test server identical to the original settings and step through the install and try to recreate the invalid character issue. But, if anyone has experienced this invalid character issue or has more information that would benefit us your help would greatly be appreciated.
Table Join Invalid Query
I have this table join below and I am getting an invalid query. How can I put the 15th line ($sql .= " group.id = master.id "; and the 17th line ($sql .= " where ".$currentrow_sql ; together. Is it even possible to do that?
Valid/Invalid Column Names
I'd like to present tabular data in HTML with the first row being the names of the columns in my database. However, I'd like them to be more presentable; for example 'I.P. Address' instead of 'ip_address'. I was wondering if a name like 'I.P. Address' could ever somehow be a valid column name or not.
Invalid MySQL-Link Resource
I'm getting the error message 'Supplied argument is not a valid MySQL-Link resource' (applies to the 3rd line of code) when the code below executes: $delete_part_no_query = "DELETE FROM prices WHERE part_no == '$part_no_to_delete'"; $delete_part_no_result = mysql_query($delete_part_no_query); $num_delete_part_no_result = mysql_affected_rows($delete_part_no_result); The query works fine and I'm under the impression that 'mysql_affected_rows' should be used to return the number of rows affected by DELETE. However, I keep getting the above error message.
Invalid Distinct Recordset Returned On An Indexed Column
I have a table with about 1.2 million records. I have an index set on a column. For close to two years, this query has worked perfectly fine: SELECT DISTINCT `Mgmt_Area` as thevalue, `Mgmt_Area` as valueid from qcdata ORDER BY thevalue Note, this is a programmatically generated query based on some user selections. This query actually is used to create a listbox. The index has 62 separate values. This query would usually return: Code:

GROUP BY With Order Inside Group
I have a problem when grouping records - I can't manipulate data inside group. For example, I have table `images` with fields `name` (name of image, not unique) and `dtadded` (date of image adding). Then, I need to get all images names with distinct names where each name must be latest added name. Sample: ------------------------------ id, name, dtadded ------------------------------ 1 name1 2007-10-15 00:00:00 2 name2 2007-10-15 00:00:00 3 name1 2007-10-16 00:00:00 ------------------------------ I need to receive 2 results (for each name) 3 - name1 - 2007-10-16 00:00:00 2 - name2 - 2007-10-15 00:00:00 If I use SQL code: SELECT images.id, images.dtadded, images.name, count(name) FROM images GROUP BY `name` ORDER BY dtadded DESC I get results 1 - name1 - 2007-10-15 00:00:00 2 - name2 - 2007-10-15 00:00:00 It groups records with first row in database, but I need last row in table for each name. Question: How can I order results in side group to get needed results as described above?

GROUP BY Only Displaying 1 Row Within Each Group
I have a database that consists of various sports schedules. The part that is NOT working is GROUP BY. I am trying to group by a column titled "sport" My current query: SELECT * FROM `otis_sports` WHERE season = 'Fall' GROUP BY sport
Now() Function
I am using now function to get current date when info is added to my table. I am using a hosting provider that is 6 hrs ahead in time zone so i always have to subtract 6hrs to get the correct time. Is there anyway I can format the time to be inserted to my time zone?

Using The AVG Function
I am trying to use this query: SELECT average(price) FROM `data` WHERE id IN ( '3', '3', '6' ) to average the price of items users select. The problem is that when a user selects a value more than once it only includes it in the average once. How can I make it average all the values?
Looking For A Particular Function
I have a Column which consists of only DATE's and an ID code. I want to enumerate all the DATE's of a certain ID to get a grand total of a ID. Does such a function exist?
Avg Function
Why doesn't this work: SELECT avg(value) as avg_value from playerstats where avg_value = '100' and stattype = 'r' group by avg_value I'm trying to select the avg_value of 'r' where the avg_value = '100'.
Last Function
How do you get the last row in a grouped query. I have a table with running balances. At the end of the day, I want to find out the last balance. select * from accounts group by date(dateCol) This always gives me the first row of the grouped column dateCol.
NOW() Function
We are developing a tool here that uses a php script to insert data into a MySQL 5.0.41 database running with the INNODB engine. While tracking a bug we noticed a strange effect. Each insert query contains a call to the NOW() function to store the create data of the record into a field automatically. Therefore we can expect in my opinion that the timestamps of the records are increasing simultaniously with the autoincrement key of the table. This actually is not the case. On the contrary the timestamps are jumping up and down with large differences. For example we have the record with ID1 that got the timestamp 14 minutes 2 seconds where ID2 got 15 minutes 15 seconds and ID3 14 minutes 9 seconds. How could this be? Does it mean that the server does not execute the statements in the order he receives them? Is it possible that it took more than a minute to execute a simple insert statement?
Max Function

Function In C
I was trying to figure out how would you write a function in MySQL using C. I saw that theres a CREATE FUNCTION syntax but am confused on how to compile and write a C function. For example if I wanted to write a function that added an extra period after every period and called it ADD_PERIOD() how would I do that. Example: x = "joe runs far." SQLSTRING = "SELECT * from Story where Sentence = '"+ADD_PERIOD(x)+"'"; this would return. joe runs far
SQL IN() Function
so i have a query such as SELECT first_name FROM users WHERE user_ID IN (5,4,8,19,8,4) and i want the first_name to be retrieved for EACH of the cases (eg. name is repeated twice for 4 and 8)
2 Queries In 1 Function?
Is it possible to query the database twice in the same function? If so is it possible to use results form the first query IN the second?
Count () Function
Cant anyone tell me why this very basic query won't process. This is to give a breakdown of Mem.heard 1-12 numbers ("where did you hear about us survey") for ea of the MOrig two user types EX: MOrig | heardof | count_heardof UserA 1 5 (times) UserA 2 6 (times) UserB 1 3 (times) UserB 2 8 (times) SELECT MOrig, heardof, count ( heardof ) as count_heardof FROM Mem GROUP BY MOrig, heardof ORDER BY MOrig
Search-function
Does anyone happen to know how to select info from the database based on multiple strings like so: SELECT title FROM food WHERE title LIKE '%New%' AND WHERE title LIKE '%York%' AND WHERE title LIKE '%restaurant%'
SUBSTR() Function
SELECT SUBSTR(message, 0, 20) FROM posts My goal is to start at the first characters on the far left, and then return 20 chars only. This function for some crazy reason seems to start at the end of the string though, which is stupid, because how do I know where the string starts?
Hidden_field Function
Does mysql 4.0.24 standard have a hidden_field function? I need to maintain state from one form to another and hidden_field is used in a script I have using mysql 3.22. If 4.0.24 doesn't have hidden_field function, what can I use with mysql 4.0.24, which is used on my server?
Date Function
I have a time stamp field in my orders table and I want to form a select statement where it returns all orders with an order time of two weeks ago from the current time or later so I can keep better track of unpaid orders. Here are the fields for the orders table orderID order_time order_status etc... SELECT orderID FROM orders WHERE ???? AND order_status=2 ORDER BY order_time ASC Thanks for any help. The date functions are a little confusing to me from the manual.
Function ROW_INDEX
I couldn't find a function that numbers the resultset of a query. First row should be 1, second row 2 etc. I searched for rownum, rowcount, rowindex etc with and without underscore's.
Password() Function
I've created a simple table called users. This table contains four columns. First_Name, Last_Name, User_Name, Password. I've used the password() function when inserting a user. I have read the documentation on using other types of encryption, but it's killing me that I can't get this to work. Robert has a User_Name of "Bob" and a password of password('tomato'). =============================== HOW I ADDED BOB insert into users values("Robert","Evans","bob",password('tomato')); 1 row added yada yada HOW I QUERY BOB select * from users where User_Name="bob" and password=password('tomato'); Empty Set =============================== That exact same query is in a tutorial for a simple PHP login form, but an empty set is returned even in the command prompt using MySQL by itself, therefore the script cannot move on.
