How to Search for Literal Square Brackets in SQL Server Stored Procedures Using Wildcards?

Search for text in stored procedures using escaped brackets and wildcards

In order to efficiently search for specific text (including square brackets) in SQL Server stored procedures, the SQL query needs to be modified to escape the square brackets.

In your original query:

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]%';

Square brackets are interpreted as wildcards by default, which may not produce the expected results. To treat them as literal characters, they need to be escaped. This can be achieved by adding escape characters to the query. In this example, use the backslash () character:

...
WHERE m.definition Like '%\[ABD\]%' ESCAPE '\'

By escaping the square brackets with a backslash, the query treats them as a single string literal, ensuring that the exact text "[ABD]" is accurately searched for in the stored procedure definition.
