TRUNCATE TABLE table_name

and

EXECUTE IMMEDIATE'TRUNC ATE TABLE table_name'

TRUNCATE TABLE <table_name> is a DDL statement.
You cannot use this directly in the PLSQL blocks.
So in order to use TRUNCATE TABLE <Table_Name> u need to execute this using EXECUTE IMMEDIATE 'TRUNCATE TABLE <Table_Name>' else the PLSQL bolck will throw an error.

EXECUTE IMMEDIATE clause is mainly used to execute dynamic SQL statements and DDL statements within PLSQL block.

EXECUTE IMMEDIATE you can frame the sql statment dynamically ,where u can also pass the table name dynamically to TRUNCATE .

EXECUTE IMMEDIATE uses late binding so performance might be faster.

It fails because there are apostrophes within the statement. How do I override the apostrophe? DECLARE cCount NUMBER; BEGIN SELECT count(*) INTO cCount FROM all_tab_columns WHERE owner = 'Owner'

I am looking for the PL/SQL equivalent of the VBScript Exec and/or Eval functions, i.e. I want to be able to dynamically create a statement, then execute it in the current PL/SQL context, e.g. declare x integer := 5; begin ExecuteStatement('x := 10'); dbms_output.put_line(x); -- should put "10" if EvaluateExpression('x*2 = 20') then

Hi, I'm now working with DB2, and I can't find out how to execute the contents of a string Statement, without using a Java/... procedure, only using SQL statements. I know that some SQBDs such as SQL Server allows it as the exemple bellow shows : EXECUTE 'SELECT * FROM Test' Is there any way to do so with DB2 ?

Hello, I'm writing an automatic SQL parser and translator from Informix to DB2. Now I'm faced with one of the most difficult things to translate, the "foreach execute procedure" functionality provided by Informix. This is the problem: the execution of the translated SQL leaves the rows in the temp table correctly but raises error SQL0480N. It's very simple to try it: ------------

I'm fairly new to DB2. I have been assigned to build a delete trigger that finds the data type of each of the table's fields so that the trigger can then build a string consisting of OLD values pre-wrapped in quote marks as needed.
