Search T-SQL (views, stored procedures, triggers) for use of a column name.

I'm sure this problem could be solved by documenting things better but...

We've had problems where we changed what a user-defined field was used for or the range of allowed values for a field and we forgot about someplace we were using that field (view, SP, etc.) that would break due to the change.

I'm looking for a way to search through all views, stored procedures, triggers, functions, etc in a given table for use of a particular field.  Searching the field name would suffice, but searching for a field from a particular table would be better.

Thanks.

try this

select * from sys.all_sql_modules m, sys.all_objects o
where m.object_id=o.object_id
and m.definition like '%Questions%'

this information is not available to you from sql server, as you acknowledge its basically down to you to document
your applications/data structures...


you can write search sql to look into your procedure/trigger/function logic  but nothing will assist you in parsing the sql
statements tat you find within so you will not be able to consistently determine where columns or even tables
are referenced... (Tables etc could be aliased in so many ways with many layers present...)


there are

Information_schema.columns /Tables/routines  tables which you can search...

something like this:

declare @myTable varchar(100) = 'myTable';
declare @myColumn varchar(100) = 'myColumn';

select * from sys.all_sql_modules m, sys.all_objects o
where m.object_id=o.object_id
and m.definition like '%'+@myTable+'%'
and m.definition like '%'+@myColumn+'%'

@HainKurt gets points for being the simplest way to get the results.
@emoreau has the best answer because the results from RedGate's SQL Search are much easier to pick through.  It looks like I'll be using this goodie a lot.

Thanks all!
