I am writing a stored procedure in mySQL and need to save log information in a text file.
Has anyone come across this?
Well, after long hours of searching I conclude that there are internal constraints in mySQL for direct writing text files.
The contour that occurs to me is to write the log messages and debugging on a table in the database, and then save the relevant records in a text file.
Similarly, grateful to all who may have tried to help.

I'm right now trying to upload a 1.3gig sql text file to phpmyadmin and each time I do it I get the following issue.
my issue
I've already tried splitting the file and editing out the CREATE DATABASE line but each time I try opening it in notepad, notepad++ and emeditor I get a bunch of random characters, clearly there's an issue with the encoding. It's not something I can easily export since another company handles that and I have no access to it. I don't care how my SQL text file is opened, I just need a way to view it and I can't find one.
Thanks for any help you can provide!
ISSUE IS SOLVED!!!
You're trying to create and then write the database named mysql. You Can't Do That™.
You should treat that database, and the information_schema and performance_schema databases, as readonly. They provide ways to retrieve information about the server via SELECT operations. Except in very specific special cases, writing those databases will at best do nothing and at worst trash your server. MySQL tries to prevent you from doing damage by throwing privilege errors when you try to alter those databases.
In a comment you mention that you are confident you can fix an issue with your system via the mysql data base. With respect, that's entirely incorrect.
I need daily load the result of a specific query to Redshift. I've already created a table on redshift that will support the results of this query but now i'm a little stuck since i can't find a good way to solve this.
So far i tried using python but im getting lots of headaches regarding line terminators in fields that basically store a description, and character encodings.
I know lots of programs that allow you to connect to a db and make querys also have an export option to csv but since i need to automatically do this everyday i don't think any of those would work for me.
Now i would like to know if maybe there are better suited options so i can start looking into them. Im not asking for a step by step how to but just for tools/programs/etc that i should start looking into.
You should look into MySQL's stored procedures and events -- using just MySQL, you can have it generate a file every day.
You can't dynamically rename the file, or overwrite it, though, so you'd need a second job which deletes the file -- this can be done with Python.
Whether you're running Windows or Linux, you should be able to schedule a batch file or python script to execute once a day, and that would be an alternate way to do that.
Does this address your question?
I'm using mysql workbench as my db client. I have two databases one is giving data mydb_1 and another is receiving the data called mydb_2.
So, below are my doubts :
How can be the data transformation is happening between these DB's?I have checked whether any stored procedure call or triggers have been written but i was unable to find out that because stored_procedures are not visible to my credentials?
I suspect may be i don't have required privilege's, if i don't have proper privilege, so even i wouldn't see the stored procedures? is it dint?
Is there any alternative way to find, how mydb_2 is getting updated?
Because of the access restriction, I was unable to see the stored procedure code.
So, I enabled the MySQL binary log to find, how the data transformation is happening between two databases for the restricted user. Even though
this didn't give entire information but partially I have found some information which can sort my problem.
I'm starting on stored procedures with mySQL and need to convert some procedures created for Oracle Database 11gR2 using UTL_FILE package to generate execution logs.
Can anyone help me, telling me if there is any similar form in mySQL?
Grateful.

The want a Perl script that will write to a data file every time update the Database MySQL. I dont mind about growth of the file since Every Items audited will be stored seperatly
Thank you will Appreciate you Help
The module Log::Log4perl provides many different ways to log events to many types of output including files. It also would allow you to set debug levels to turn this off if you needed to.
