How to Search for Text Containing Square Brackets in SQL Server Stored Procedures?

Text search method containing square brackets in SQL Server stored procedures

In SQL Server, searching text within stored procedures is critical for code maintenance and optimization. However, including special characters like square brackets can present challenges.

Question:

You may have an issue where your SQL query cannot find the exact instance of '[ABD]' (including square brackets) in the stored procedure. The reason is that the square brackets are treated as wildcards and not part of the search string.

Solution:

To fix this problem, the square brackets need to be escaped. In T-SQL, this can be achieved by adding escape characters (such as backslash). By escaping the square brackets, they are treated as the literal part of the search string.

The updated query looks like this:

SELECT DISTINCT
       o.name AS Object_Name,
       o.type_desc
FROM sys.sql_modules m
       INNER JOIN
       sys.objects o
         ON m.object_id = o.object_id
WHERE m.definition LIKE '%\[ABD\]%' ESCAPE '\';
Copy after login

Instructions:

By adding the escape character ( ) before the square brackets, you are essentially instructing the query that they should not be interpreted as wildcard characters, but should be included as part of the search string. This allows for an exact match of the '[ABD]' text in the stored procedure.
