Hai,

Go through this documentation regarding sql trace

The SQL trace is a tool, which allows displaying and analyzing the contents for the database calls, which are made by the reports and transactions written in ABAP/4. It monitors programs and transactions on the database level. With the help of this facility for every open SQL instructions, you can display, about which SQL Embedded (DECLARE, OPEN, FETCH) Statement have been executed, besides analyzing the system performance.

Steps to Creation

• From R3 screen, select system –-> Utilities –-> SQL trace. Or Enter transaction ST05.

• Click the trace on button.

• Enter the user name whose programs are going to be traced.

• Execute the program or transaction you want to trace.

• Return to SQL trace initial screen and press the button SQL trace off. This switching off is necessary because if it is not done then SQL trace will trace each and every program executed by a particular user. And it is quite expensive in terms of memory and time of the system.

Analyzing The Trace File

To analyze the created trace, press the button list trace. Using this file you can see exactly how the system handles database requests. The first screen of the SQL trace data file displays each measured database requests, the application made. The trace file records when the request occurred and its duration.

To display dictionary definition information about the table field, position the cursor on the table field and click on the DDIC info button. When this button is clicked, it displays system information like object name, table class, whether buffering is allowed or not i.e. information related to dictionary.

Explain SQL: This button provides the functionality, which includes the utility for providing detailed information about the SQL Operation Strategy followed by the underlying database system. You need to click on Explain SQL button. The system displays the execution plan for SQL statements. Here you can display the actual SQL statement like Select, which fields are being accessed, Table being accessed, all where conditions.

ABAP/4 Display Gives you the actual ABAP/4 code.

More information gives the detailed information for time, select statement, client, number of records selected etc. Replace variable will display the SQL statement with another variables.

I hope this will be helpful....
