Search All Columns in All Tables for a string

,

This procedure can search all columns in one or all tables for a specified string. Prints out the TableName.ColumnName that the string is found in...

--     Example Calls
--     EXECUTE spFindTextInColumns MyTable, 'tcart' --search a specific table
--        
--     EXECUTE spFindTextInColumns default, 'tcart' --search all tables

BUG FIX : (2003/01/20)

Changed

SELECT @columnName = [COLUMN_NAME],

to:

SELECT @columnName = '[' + [COLUMN_NAME] ']',

to avoid: Line 1: Incorrect syntax near '~'

Thanks to Avraham de-Haan for pointing this one out.
