Searching SQL Code via sys.sql_modules

I've been used to searching stored procedures via tsql like this.

SELECT * FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_DEFINITION LIKE '%mytablename%'

The problem this encounteres however is that ROUTINE_DEFINTION is NVARCHAR(4000) and hence only returns the first 4000 characters of a stored procedure. The alternative below searches the entire codebase.

SELECT DISTINCT
   SCHEMA_NAME(schema_id) as schema_name
  ,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 '%mytablename%'
ORDER BY 1,2

Converting a datestring to datetime (yyyymmddhhmmss)

This uses STUFF to format a datestring correctly.

declare @datestring varchar(20) = '20170504103253'
-- Add colons and space to format datetime
SET @datestring = STUFF(STUFF(STUFF(@datestring,13,0,':'),11,0,':'),9,0,' ')
select @datestring
-- Convert ....
select convert(datetime,@datestring)
