Taking table name as input in sql

问题

I need to take a table name as input from user to my PL / SQL script and then update that table. I am not sure if this is possible because ORACLE might have problem parsing the script.

Please guild me as to how to solve this problem.

Thnx.

Use EXECUTE IMMEDIATE. It allows you to build a SQL statement as a VARCHAR2 string and then execute that statement.

eg.

lStr := 'UPDATE '||table-name||' SET COLUMN-NAME = VALUE';

EXECUTE IMMEDIATE lStr;

COLUMN-NAME and VALUE can also be changed dynamically of course.
