T-SQL Tuesday #104: Code I’d Hate To Live Without

It’s T-SQL Tuesday time again, and this month the host is Bert Wagner (b|t) whose topic of choice is “write about code you’ve written that you would hate to live without.”

There are so many different scripts I use every day it’s difficult to pick just one, but I find myself using the following script frequently. I don’t have this wrapped into a stored procedure because I’m often working with different clients who may or may not have permission to create a stored procedure, or they may have a change process to follow when any objects are to be added to the production database.

The script accepts 2 input variables:

@SearchPattern – This is going to be the text we’re trying to find amongst all the object definitions, columns, and jobs (see @incjobs variable).

@incjob – I do not search the agent jobs by default, but you can set this flag to 1 if you want. When this is set to 1, I look for a match in the job step along with the job name.

In the example below, I used the AdventureWorks2012 database and searched for ‘%hiredate%’

/*dan.clemens drcdba.com*/
DECLARE @SearchPattern NVARCHAR(128)
       ,@incjob bit

SET @SearchPattern = '%%'
SET @incjob = 0 --Set to 0 to ignore jobs

/*Creates list of all tables and associated columns
to do easy multi-column comparisons with a like.*/
DECLARE @tabletbl TABLE
(
objectid int,
tablename varchar(max),
tabletype varchar(5),
tablecolumns varchar(max)
)
insert into @tabletbl
select o.[object_id]
       ,o.name
       ,o.[type]

LEFT JOIN @tabletbl AS t ON t.[objectid] = o.[object_id]
WHERE (lower(OBJECT_DEFINITION(o.object_id)) LIKE lower(@SearchPattern)
       OR (t.tablecolumns like lower(@SearchPattern)
OR t.tablename LIKE lower(@Searchpattern)))

If you find this script useful, you’re welcome to use it. I look forward to seeing what others contribute! Thank you Bert for an awesome topic!

As always, thank you for reading.
