Question

How do I execute an SQL string statement in DB2? I’m using IBM Data Studio.

Answer 1

Do you mean executing a dynamic SQL string? Something like:

DECLARE stmt VARCHAR(1000);
DECLARE my_table VARCHAR(50);
SET my_table = 'DEPT_'||deptNumber;
SET stmt = 'SELECT * FROM '||my_table;
PREPARE s1 FROM stmt;
EXECUTE s1;

You can only do that in a stored proc though. One defined as CREATE PROCEDURE GetDeptInfo (deptNumber VARCHAR(5)) for this example. Read about EXECUTE and PREPARE in the db2 docs http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp
