Search all tables, all columns for a specific value SQL Server [duplicate]

Solution 1:

I've just updated my blog post to correct the error in the script that you were having Jeff, you can see the updated script here: Search all fields in SQL Server Database

As requested, here's the script in case you want it but I'd recommend reviewing the blog post as I do update it from time to time

DECLARE @SearchStr nvarchar(100)
SET @SearchStr = '## YOUR STRING HERE ##'

SELECT TableName, ColumnName, ColumnValue, ColumnType, COUNT(*) AS Count FROM #Results
GROUP BY TableName, ColumnName, ColumnValue, ColumnType

Solution 3:

You could query the sys.tables database view to get out the names of the tables, and then use this query to build yourself another query to do the update on the back of that. For instance:

select 'select * from '+name from sys.tables

will give you a script that will run a select * against all the tables in the system catalog, you could alter the string in the select clause to do your update, as long as you know the column name is the same on all the tables you wish to update, so your script would look something like:

select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables

You could also then predicate on the tables query to only include tables that have a name in a certain format, or are in a subset you want to create the update script for.

The below Query works but very slow... copied from vyaskn.tripod.com

Declare @SearchStr nvarchar(100)
