如何使用SSIS或TSQL创建以元素列中的唯一值命名的新表，并包含代码，名称，seq和活动列中的值？

Answer 1

DECLARE @element VARCHAR(25)

DECLARE ElementCursor CURSOR FOR
    SELECT DISTINCT
        Element 
    FROM
        dbo.[Validation]

OPEN ElementCursor

FETCH NEXT FROM ElementCursor
INTO @element

    WHILE @@FETCH_STATUS = 0
    BEGIN
       BEGIN TRY
          DECLARE @SQL NVARCHAR(MAX)
          SET @SQL = '
                IF OBJECT_ID(' + CHAR(39) + concat('v_',@ElementID) + CHAR(39) + ') IS NOT NULL 
                    BEGIN
                        DROP TABLE ' + concat('v_',@ElementID) + ' 
                    END

                CREATE TABLE '+ concat('v_',@ElementID) + ' (
                    Code VARCHAR(10) NULL
                    ,name VARCHAR(50) NULL
                    ,seq INT NULL
                    ,active BIT NULL
                )

             INSERT INTO ' + concat('v_',@ElementID) + ' (Code,name,seq,active)
             SELECT
                Code
                ,name
                ,seq
                ,active
             FROM
                dbo.[Validation]
             WHERE
                element = ' + CHAR(39) + @element + CHAR(39)

         PRINT @SQL
         EXECUTE (@SQL)

       END TRY
       BEGIN CATCH
          EXECUTE usp_GetErrorInfo;
       END CATCH

        FETCH NEXT FROM ElementCursor
        INTO @element
    END

CLOSE ElementCursor
DEALLOCATE ElementCursor

我现在注释掉了递归位：

编辑：这是工作代码！感谢百万马特

我的代码

          USE [vPhiladelphia-CV1]
GO

CREATE PROCEDURE jmkParsingValidationTables AS


DECLARE @ElementID varchar(30)
DECLARE @value varchar(30)

DECLARE MY_CURSOR CURSOR FOR 

    SELECT DISTINCT [element]
    FROM [dbo].[Validation]

OPEN MY_CURSOR
    FETCH NEXT FROM MY_CURSOR 
    INTO @ElementID
    WHILE @@FETCH_STATUS = 0

    BEGIN TRY
        DECLARE @SQL NVARCHAR(MAX)
        SET @SQL = '
            IF OBJECT_ID(' + CHAR(39) + concat('v_',@ElementID) + CHAR(39) + ') IS NOT NULL
                BEGIN
                    DROP TABLE [' + concat('v_',@ElementID) + ']
                END

            CREATE TABLE [' + concat('v_',@ElementID) + '] (
                code VARCHAR(300) NULL
                ,name VARCHAR(300) NULL
                ,seq VARCHAR(300) NULL
                ,active VARCHAR(300) NULL
            )

            INSERT INTO [' + concat('v_',@ElementID) + '] (code,name,seq,active)
            SELECT
                code
                ,name
                ,seq
                ,active
            FROM
                [Validation]
            WHERE
                element = ' + CHAR(39) + @ElementID + CHAR(39) 

            PRINT @SQL  
            EXECUTE (@SQL)

            FETCH NEXT FROM MY_CURSOR INTO @ElementID

    END TRY

    BEGIN CATCH
        EXECUTE usp_GetErrorInfo;  
    END CATCH

CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR
