Procedura, która zwraca wszystkie wystąpienia podanej w parametrze wartości, w formacie [NAZWA_SCHEMATU].[NAZWA_TABELI].[NAZWA_KOLUMNY].

Stwórz w bazie danych procedurę:

CREATE PROC SearchAllTables
(
	@SearchStr nvarchar(100)
)
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 = ''
