search all tables sql

The following query, original from this site, searches all integer columns only to find a value. It does not find string but integer value. This query may run faster on large databases and can be more usefully. Basically your search by table id which is usually an index field and runs faster.

CREATE PROC SearchAllTablesForValue
(
	@value int
)
AS
BEGIN

	CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

	SET NOCOUNT ON

	DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
	SET  @TableName = ''
	SET @SearchStr2 = QUOTENAME( @value,'''')

	WHILE @TableName IS NOT NULL
	BEGIN
		SET @ColumnName = ''
		SET @TableName = 
		(
			SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
			FROM 	INFORMATION_SCHEMA.TABLES
			WHERE 		TABLE_TYPE = 'BASE TABLE'
				AND	QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
				AND	OBJECTPROPERTY(
						OBJECT_ID(
							QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
							 ), 'IsMSShipped'
						       ) = 0
		)

		WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)
		BEGIN
			SET @ColumnName =
			(
				SELECT MIN(QUOTENAME(COLUMN_NAME))
				FROM 	INFORMATION_SCHEMA.COLUMNS
				WHERE 		TABLE_SCHEMA	= PARSENAME(@TableName, 2)
					AND	TABLE_NAME	= PARSENAME(@TableName, 1)
					AND	DATA_TYPE IN ('int')
					AND	QUOTENAME(COLUMN_NAME) > @ColumnName
			)
	
			IF @ColumnName IS NOT NULL
			BEGIN
				INSERT INTO #Results
				EXEC

					'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) 
					FROM ' + @TableName + ' (NOLOCK) ' +
					' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2

	SELECT ColumnName, ColumnValue FROM #Results
