So i have a query that uses UNION ALL for alot of different rows that are using similar variables that i dont want to have to change in each select statement so i want to use variables.

So how do you set up variables in oracle both integers and strings, so in other words how would you make the code below work
var myNum = 150
var myString = 'smith'

AND LAST_NAME = myString

Open in new window

using sqlplus try the following
var myNum number
var myString varchar2(10)

exec :myNum := 150;
exec :myString := 'smith'

SELECT :mynum, :mystring from dual;

Open in new window

What tool are you using to run it?

What I posted was for sqlplus.

Never used SQL Developer.  Have only read a few things about it.

Are you running your scripts in script runner?  This is supposed to imitate sqlplus functionality.

Never having used it, I'm down to Googling.  Does the following link help?

If you want a bind variable to have a default value, you can put that value in the value element.
