问题
I have a query
select * from table where name in ('52 T&M', '60 T&M');
The "&" is causing the query to expect a parameter. How do I qualify the "&" in the query to sting so that the query can find string with the "&" character in them?
回答1:
I would normally use set define off as suggested by omg but it is also possible to do it like this:
select *
from table
where name in ('52 T'||Chr(38)||'M', '60 T'||Chr(38)||'M');
回答2:
The ampersand ("&") is a character interpreted by SQLPlus as a variable placeholder. Use:
SET DEFINE OFF
回答3:
I assume you use sqlplus, so execute before
set scan off
