How to track and log SQL Server stored procedures?
Create a table to log stored procedure activity. Create a procedure in each user database that logs to the central table. Gradually add a call to this logging procedure to the rest of your stored procedures.

How to use print statement to track execution as?
SQL Server returns messages after a batch of statements has been executed. Normally, you’d use SQL GO to indicate the end of a batch and to retrieve the results: PRINT ‘1’ GO WAITFOR DELAY ’00:00:05′ PRINT ‘2’ GO WAITFOR DELAY ’00:00:05′ PRINT ‘3’ GO.
How to create stored procedure in SQL Server?
Well, in order to minimize the amount of code you’ll need to call in each stored procedure in your user database (s), you’ll want to create a stored procedure in each database (this will allow you to grab context to DB_ID () without having to use a local variable in each procedure).
How to encapsulate transaction in a stored procedure?
I need to perform an UPDATE and an INSERT in a single transaction. That code works fine on its own, but I’d like to be able to call it easily and pass in the required parameters. When I try to nest this transaction in a stored procedure I run into lots of syntax errors. How can I encapsulate the following code so it can be easily called?
Why do we need to log from inside a transaction?
It’s nice to log information to a table from stored procedures, triggers, functions and so on. This information helps to understand what has happened during the execution. But if the operation fails, typically the transaction is rolled back so everything written into the database inside this transaction will not be persisted.
Can a CLR procedure be used to log data?
So now we can also use a CLR procedure to log any interesting data. By using either of these mechanisms you can ensure that the information logged during a transaction is persisted even when the transaction is rolled back. This is an enormous benefit from problem solving point of view.
Why do I need a stored procedure in MySQL?

Why is there no logging in SQL Server?
In many environments there is a lack of consistent logging from stored procedures – if there is any logging at all. In general, we tend to leave it up to the application to record any errors, but in systems with many different applications, it can be tedious to collect exception information and figure out which stored procedures are having issues.
How to create a procedure name in MySQL?
CREATE PROCEDURE procedure_name () BEGIN DECLARE EXIT HANDLER FOR SQLEXCEPTION BEGIN SHOW ERRORS; –this is the only one which you need ROLLBACK; END; START TRANSACTION; –query 1 –query 2 –query 3 COMMIT; END If query 1, 2 or 3 will throw an error, HANDLER will catch the SQLEXCEPTION and SHOW ERRORS will show errors for us.
