Find Value in a database column

The below article content is taken from this excellent articly by David. http://blog.davidyardy.com/blog/archive/2008/08/16/sql-server-ndash-find-field-value-in-database.aspx

The following is a SQL Script that can be run in a database to return all tables and columns where a particular value is present.  This can be used for strings or values with a small modification.This type of thing is great when moving applications/products between servers.  This is certainly a good script to include in your master table to be used over and over.

DECLARE @value VARCHAR(64)
DECLARE @sql VARCHAR(1024)
DECLARE @table VARCHAR(64)
DECLARE @column VARCHAR(64)
SET @value = 'valuehere'
CREATE TABLE #t (
    tablename VARCHAR(64),
    columnname VARCHAR(64)
)
DECLARE TABLES CURSOR
FOR
    SELECT o.name, c.name
    FROM syscolumns c
    INNER JOIN sysobjects o ON c.id = o.id
    WHERE o.type = 'U' AND c.xtype IN (167, 175, 231, 239)
    ORDER BY o.name, c.name
OPEN TABLES
FETCH NEXT FROM TABLES
INTO @table, @column
WHILE @@FETCH_STATUS = 0
BEGIN
    SET @sql = 'IF EXISTS(SELECT NULL FROM [' + @table + '] '
    --SET @sql = @sql + 'WHERE RTRIM(LTRIM([' + @column + '])) = ''' + @value + ''') '
    SET @sql = @sql + 'WHERE RTRIM(LTRIM([' + @column + '])) LIKE ''%' + @value + '%'') '
    SET @sql = @sql + 'INSERT INTO #t VALUES (''' + @table + ''', '''
    SET @sql = @sql + @column + ''')'
    EXEC(@sql)
    FETCH NEXT FROM TABLES
    INTO @table, @column
END
CLOSE TABLES
DEALLOCATE TABLES
SELECT *
FROM #t
DROP TABLE #t
