How to search all columns of all tables in a microsoft sql database for a keyword (including any data type)

Pages: 1 2

Hey,

I’ve been working on a very large unknown database (over 45 tables) where the reverse engineered schema diagram was quite chaotic. Having the task to find several needles in the haystack I searched the internet and found the very useful script at:

http://vyaskn.tripod.com/search_all_columns_in_all_tables.htm  (pasted below).

However, one limitation I noticed was that the script only searched (‘char’, ‘varchar’, ‘nchar’, ‘nvarchar’).

With quick additions to the AND DATA_TYPE IN (‘char’, ‘varchar’, ‘nchar’, ‘nvarchar’)  line, the stored procedure can be tailored to search IDs, and even Binary Large Objects (e.g. PDFs).

For me, I wanted to find where specific IDs are reused (and unfortunately foreign keys were not set) so I change the line to AND DATA_TYPE IN (‘uniqueidentifier’) .

Cheers!  The code below:

Create this procedure in the required database and here is how you run it:

--To search all columns of all tables in Pubs database for the keyword "Computer"
EXEC SearchAllTables 'Computer'
GO

On the next page we display the complete code.
