Question

如何在SQL Server 2008中截断选择性表，我有一个表格列表，可以在截断过程中排除。

有人可以指导我吗？

您只需运行TRUNCATE TABLE yourTableName即可。如果您有列表，则可以运行以下命令：

CREATE TABLE #truncateTables(name nvarchar(255))

INSERT INTO #truncateTables(name) VALUES(N'dbo.yourTable1'),(N'dbo.yourTable2')

DECLARE cur CURSOR FOR
SELECT name FROM #truncateTables

OPEN cur

DECLARE @sql nvarchar(max), @tabname nvarchar(255)

FETCH NEXT FROM cur INTO @tabname

WHILE @@FETCH_STATUS = 0 BEGIN
    SET @sql = N'TRUNCATE TABLE '+@tabname
        BEGIN TRY EXEC(@sql)
    END TRY
    BEGIN CATCH -- if a foreign key constraint exists
        SET @sql = N'DELETE FROM '+@tabname
        EXEC(@sql)
    END CATCH

    FETCH NEXT FROM cur INTO @tabname

END

CLOSE cur
DEALLOCATE cur

DROP TABLE #truncateTables
