TOAD thinks &String as bind variable

问题

I am developing some ETL with Oracle Data Integrator and sometimes test parts of my code by TOAD. Today I had a problem with TOAD I had a line like

AND column_value like('DEV&PROD')

when I tried to run the SQL which includes filter above, TOAD ask for the value of PROD, it thought like PROD is a bind or substitution variable. Is there any option in TOAD settings to turn this feature of. I am using bind variable with a column (:), and my data includes & so I need to use it.

This code works in ODI perfectly, I only need a solution for TOAD. Thanks in advance.

回答1:

1) start your script with set define off; (and run whole script with F5 key)
or
2) use 'DEV&'||'PROD' instead of 'DEV&PROD'
or
3) set another prefix symbol for variables

set define ~;
select 'drag&drop', ~column_name from ~table_name;

(you will be prompted for column_name and table_name, but not for 'drop')

In addition - will work in any tool or SQL prompt:

SELECT ('DEV'||'&'||'PROD') val FROM dual
/

-- Q-quote operator introduced in Oracle 10g --
SELECT 'DEV' || q'[&]'||'PROD' AS val FROM dual
/

Using Egor's or my examples - copy/paste, enter 1 for :bind_var :

SELECT 'DEV&'||'PROD' val FROM dual
 WHERE :bind_var = 1
/
