Searching a string value in all columns in a table

The code below allows you to search for a value in all text data type columns such as (char, nchar, ntext, nvarchar, text and varchar).

The stored procedure gets created in the master database so you can use it in any of your databases and it takes three parameters:
stringToFind - this is the string you are looking for. This could be a simple value as 'test' or you can also use the % wildcard such as '%test%', '%test' or 'test%'.
schema - this is the schema owner of the object
table - this is the table name you want to search, the procedure will search all char, nchar, ntext, nvarchar, text and varchar columns in the table

Create the following stored procedure in master database.

**************************************************************************
USE master
GO
CREATE PROCEDURE sp_FindStringInTable @stringToFind VARCHAR(100), @schema sysname, @table sysname
AS
DECLARE @sqlCommand VARCHAR(8000)
DECLARE @where VARCHAR(8000)
DECLARE @columnName sysname
DECLARE @cursor VARCHAR(8000)
BEGIN TRY
SET @sqlCommand = 'SELECT * FROM ' + @schema + '.' + @table + ' WHERE'
SET @where = ''
SET @cursor = 'DECLARE col_cursor CURSOR FOR SELECT COLUMN_NAME
FROM ' + DB_NAME() + '.INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = ''' + @schema + '''
AND TABLE_NAME = ''' + @table + '''
AND DATA_TYPE IN (''char'',''nchar'',''ntext'',''nvarchar'',''text'',''varchar'')'
EXEC (@cursor)
OPEN col_cursor
FETCH NEXT FROM col_cursor INTO @columnName
WHILE @@FETCH_STATUS = 0
BEGIN
IF @where <> ''
SET @where = @where + ' OR'
SET @where = @where + ' ' + @columnName + ' LIKE ''' + @stringToFind + ''''
FETCH NEXT FROM col_cursor INTO @columnName
END
CLOSE col_cursor
DEALLOCATE col_cursor
SET @sqlCommand = @sqlCommand + @where
--PRINT @sqlCommand
EXEC (@sqlCommand)
END TRY
BEGIN CATCH
PRINT 'There was an error'
IF CURSOR_STATUS('variable', 'col_cursor') <> -3
BEGIN
CLOSE col_cursor
DEALLOCATE col_cursor
END
END CATCH
