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. Check to make sure object exists.'
IF CURSOR_STATUS('variable', 'col_cursor') <> -3
BEGIN
CLOSE col_cursor
DEALLOCATE col_cursor
END
END CATCH
