Update Automation
I'm working on a project with PHP/MySQL that my require some automation but I'm not quite sure how to go about it. Basically there will be a MySQL database consisting of a number of images and reports that correspond to different customer orders. When a user is logged in he can go to page to view an order history with these reports. What my client was interested in doing is sending me .csv files (or whatever files are needed) that I would upload to MySQL on a daily basis. These files would basically be the customer orders. So, basically the customer reports would be updated at the end of the day so they are kept current. Is there a way to setup an automated process like this? Where either he could send me files to import into MySQL or where my client could do so directly? I'm working on a Windows machine.

OLE Automation Date Conversion
I have a database with many datetime columns that are stored as floating point numbers that represent the number of days since Jan 01, 1900 - or I guess it's really since Jan 00, 1900. This was done because the datetime field in MySQL had a precision of only 1 second and we needed fractional seconds - I'm not sure if this constraint is still true. Currently we don't have time to write any frontend applications to query the database so I want to make it easier for people to filter the data without having to convert to/from a number. What I'm looking for is some type of MySQL conversion function to do the following: SELECT * FROM mytable WHERE timestamp ConvertToNumber("2007/5/25 1:23 PM") SELECT ConvertToDateTime(timestamp), someothercolumn, FROM mytable The only related methods I could find where CAST() and CONVERT() but I couldn't find any way to use them to produce the results I wanted.

Automation / Task Scheduler
Here is what I need to do: send out an email to a registered user's email stored in a table. This email should be sent once the registration date and the current date is equal or greater then 30 days. Can I schedule a task (function or procedure) within MySQL to check the registration table every day and send out email, if needed?

Is this The Only Solution for that ?

Execution Time
After we execute a statement in mysql, it reports the query execution time in the format: n rows in set (t sec). We may do something like this to get the execution time: $time_start = getmicrotime(); mysql_query( "" ); $time_end = getmicrotime(); $time = $time_end - $time_start; But it includes extra CPU time to run two getmicrotime() functions and one subtraction. Is there any way to obtain the execution time directly from mysql without running extra functions or calculations?

Asynchronous Execution
I have the following situation php file 1: an SQL writes data to the database php file 2: an SQL reads data from the database Some users report errors that MIGHT be due to the SQL in file 1 not being executed, before they click on a link to open file 2. So they get out of date information. I want to know if this is technically possible, whether this might indeed be the problem, that if a database is very busy, that SQL statements are queued and data retrieval may read obsolete out of date information, because the data storage SQL has not been executed yet. And if this is the problem, I would like to wait in file 1 until the data has actually been written.

Improve The Execution Time
i am new to db2 want to ask questions about the performance of my sql commands for a view based another 3 views the sql commnads are as following: create view b_central_subgroup as select communicator as central_member, project_id as project_id from b_normalized_communicator intersect select initiator as central_member, project_id as project_id from b_normalized_initiator intersect select monospeaker as central_member, project_id as project_id from b_normalized_monospeaker it takes 4.4 seconds to execute this sql. it likes that the time is the summ of the other three views. Can the execution time be reduced through some other methods? If it is possible , then how ?

Query Execution Too Slow!
I have migrated from MySQL 4.1.22 to MySQL 5.0.45. Many of the queries that were working on my old server is working too slow in my new server(MySQL version 5.0.45). I am not aware why is this happening. Actually there is no error message or query failing. The query is executing, but the time taking to execute the query is too long. This problem is not occurring for all queirs, but only for some complex queires, that is queries with Left Join or Right Join, Group By etc. I have also checked the MySQL details through SSH(that is by mysql> SHOW VARIABLES;) Now one thing I found is there is lot of difference in key_buffer_size, table_cache, join_buffer_size, read_buffer_size, read_rnd_buffer_size , table_cache etc between my new server MySQL and old server MySQL. Will this be the reason for query execution taking too much time. Can any one guide me why this is happening. The striking thing is that these quires was working very much fine and faster in my old server.

Measure Execution Time
I would like to measure the execution time of my queries in order to evalutate the performance in/decrease for different changes. Even if I use 'sql_no_cache' the query executes MUCH faster the second time I run it, and is therefore not representative of the true performance. How to I avoid this problem? I'm using MySQL 4.1 on a windows server 2000. I be glad to get an explanation to why the query executes faster the 2nd time.

Last Query Execution Time
Is there a way to retreive the elapsed time for the prevously executed query? Alternatively, Is there a way to query the current time in fractions of a second?

Mysql Execution Sequence
I need to retrieve the last value from a column in a mysql table, perform some actions on it, then add 1 to the original value and store a new entry. I am worried that if multiple users access the database at the same time I will end up with duplicated 'new values'. Does mysql complete execution of a script before it allows access to another user or do I need to 'lock' the table in some way while the script executes?

Query Log With Execution Time?
I have developed a big property portal web site and have probably written about 1000 different SQL queries in the process (OK, maybe only 500 or so) but a lot. The site is now gaining popularity and although it is on a dedicated server I want to make sure that everything is running smoothly. I have optimised several tables with indexes etc. and have sped up certain tasks, but would like to know if there are any other queries that take too long and should be optimised. Is there a way to log all queries together with the time it took to execute the query? Is this already logged and if so - where is it?

Slow Query Execution
Right now I am fazing one issue which is getting hell out of me. I am explaining the issues step by step. 1.I have one site running from last 3 years with large database and there is one main table which has maximum load. 2.Now, I have redesigned the site with lots of changes within this table too. 3.The problem is that the server is same, queries are same but output in the new database is taking 50 times more execution time. 4.I also just copy paste the table, and fire the same query... Strange even that is not working... Is it something where newly added table or database is having issues in the server? I have tried all, compared the structures of the data and table but still the query result is too slow on live testing sever. While same query in main site of same server is running perfectly.

Copying Table To Disk During Execution
I seem to be having an issue with a query's results being paged out to disk during runtime. I notice in processlist it saying "Copying to tmp table on disk". select col1, col2, count(ip) as 'COUNT' from db.table group by 2 order by 1, 3; None of the columns are a primary/foreign or an index. This query returns 92K rows and has taken anywhere from 50 seconds to run to over 1.5 minutes. The table size on disk is around 33MB. After doing some research i found that i should be changing the tmp_table_size system variable. Originally it was set to the MySQL default, 33554432. I set the varaible to 90,000,000 and it still started paging out to the disk (this was the only query running at the time). I would think that 90MB in space would have been enough to handle the query since that would assume over 600K row size. I actually had some trouble setting the tmp_table_size for the global variable but was able to change it as a session variable. I have also tried altering the query_cache variable (which has only slowed the query down - currently it sits at a size of 50MB) and also the sort_buffer_size but neither have made a difference. What is the magic variable that i should be messing with?

Query Execution Time In PHP Script
I am interested in displaying the query execution time as mysql does from the console, but using php. I've looked everywhere for this and can't find anything. Does anyone know how to display this information to the browser via php? The information must be there since the console provides it. I checked the php function mysql_info(), but that only shows records, duplicates, deleted, matches, changed, warnings, etc. Didnt see any specific php function for getting execution time.

Measure Execution Time Of Mysql Script
I am trying to measure the total execution time of a mysql script that I run using the mysql command line client in batch mode (-e "source myscript"). The --tee option does not work for the batch mode so that I could then gather and add up the execution times of the SQL queries as logged by the server. Adding a tee command in the script itself is not working. Using the time command (in Linux , and timex is not available) on the mysql program is also not helpful as I think it does not include the execution time of the queries on the mysql server side, but only the system and user times corresponding to the client process.

Check Query For Syntax Prior To Execution
I was wondering if it was at all possible to check an SQL query prior to execution for syntax errors? A method which wouldn't alter the data to which the SQL statement related to. I'm guessing you could perform a transaction of sorts, but is there another way?

Printing Debugging Info Into A File During Script Execution
I've got a very large script (~50GB) that takes a very long time to execute. I want to echo text into a output file at various places during the execution. Something like: ... select 'message 1'; ... select 'message 2'; ... If the script is: doit.sql, then I just do: mysql -uUSER -pPASS < doit.sql > log.out The problem is that I can't see the information in log.out because STDOUT is not flushed until the buffer is full. So, I thought I'd do something like: select 'message 1' into outfile 'log.out'; Unfortunately, mysql doesn't append to log.out. So, how can I get logging information into the log.out file so that I can let the script run in the background and just do something like: tail log.out to see the most recent messages and know that they are not being kept in some buffer pending output. This script takes about 2-3 days to complete and I want some method of seeing what things the script has done. The messages I have in the sql script make it very easy for me to know just what has been done, but don't do me any good if they're in some darned STDOUT buffer.

Slow Execution For A Left Outer Join Query
Whats likely to be the cause of slow execution for a left outer join query? The original query joins three tables but even if I narrow it down to one it still takes a long time to execute. $query = "select distinct materials.* from materials"; $query .= " left outer join materials_products on materials.material_id = materials_products.material_id"; There's 914 rows in the materials table and 1348 row in the materials_products table Is it likely to take a long time for this amount of data or is there likely to be a problem in the table(s) set up or query?

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.
