Variable inside a variable
Date: 30 May 2004 00:14:04 -0700
This is a little hard to explain, but please bear with me ...
I'm writing a package in PL/SQL and in one of my procedures I am retrieving data from a db table. This table has a column which possibly has a variable name in it.
By using a cursor I have a variable holding the value which is another variable name of the. How can i use the variable I have with dsql so that i have a sql statement that gives uses the value of the variable that is named in the initial variable.
v_myVar1 := 'foo';
v_myVar2 := 'v_myVar1';
v_sqlString := 'SELECT '||v_myVar2||' FROM DUAL';
it will give me v_myVar1 when i want the output to be foo!??!
I'm guessing i want some like eval that executes the variable then parses it to the string.
Does anyone have any ideas?
