zsql: A tool to execute SQL statements directly in sap

1 in zsql: A tool to execute SQL statements directly in sap Posted by Basar Ozgur Kahraman in ABAP Development on Oct 9, :06:43 AM Sometimes i need to write sql statements and get results immediately in abap. To handle this requirement, i create a test program, write my sql in it and debug to investigate results. It's difficult and time consuming work so I have developed an SQL tool for ABAP Programmers to allow them to run select statements directly in SAP, confirm or discover relationships and see data side by side. Installation: 1- Create an executable program and named it "ZSQL" in se38 2- Download attached zsql.txt.zip file and Upload into zsql(or copy&paste) 3- Create screen '0100' 4- Go into screen '0100', choose "Flow Logic" tab and add flow logic code as below 5- Go to layout of screen and add a "Custom Control" and name it "CC_SQL" 6- In layout add two buttons -Run: FctCode: "RUN" -Exit: FctCode: "EXIT" 7- Activate screen 8- Activate program Flow Logic Code: PROCESS BEFORE OUTPUT. MODULE status_0100. PROCESS AFTER INPUT. MODULE user_command_0100. Notice: - Each FROM/JOIN clause must be in new line - Table names&aliases and From/Join clauses must be in the same line - Don't use SELECT SINGLE - Don't use INTO statement - Doesn't support aggregate functions(e.g. SUM, MAX, AVG) - DELETE/UPDATE statements are supported only in test systems Examples:
