Using declare variables in Oracle

Question

I am having a syntax issue with the declaration in Oracle. I am using these variables on MS SQL server and they work just fine; however, how do I declare these in Oracle?

Use in MS SQL server:

DECLARE @FROM_DT DATETIME
DECLARE @END_DT  DATETIME
DECLARE @LOCATION  VARCHAR(100)

SET @FROM_DT = '04/01/2011'
SET @END_DT =  '05/09/2011'
SET  @LOCATION ='VA'

You cannot declare variables outside of a PL/SQL block.

The format of variable declarations inside a PL/SQL block is described very detailed in the manual (including examples):

Simple but informative. «Cannot declare variables outside of a PL/SQL block» is the important bit most tutorials omit. Also, other documents explain the VARIABLE syntax and do not mention it's a SQL*Plus internal command.

You may pass variables to other sql files. It's not exactly what you want but it helps me to solve some problems without using blocks.

For Instance my config.sql file:

@drop.sql 'MY_USER'

my drop.sql file:

DROP USER "&1" CASCADE;
