Question

我想基于数组中的值多次运行查询。我离我很近，但是我不知道如何通过迭代调用查询。我在网上找到的示例显示“执行过程”，但随后没有显示过程的内容，因此我不知道如何让查询以正确的方式引用过程。

在下面的代码中，我首先显示了迭代过程，然后有一个名为QueryIWantToUse的过程。


INSERT INTO @ids (id)
    SELECT 'CTMContactOrigin' UNION 
    SELECT 'PMMParameters' UNION 
    SELECT 'TAXTABLE'
DECLARE @i INT
DECLARE @cnt INT

SELECT @i = MIN(idx) - 1, @cnt = MAX(idx) FROM @ids

WHILE @i < @cnt
BEGIN
     SELECT @i = @i + 1

     DECLARE @id = SELECT id FROM @ids WHERE idx = @i

     EXEC QueryIWantToUse @id
END

--QueryIWantToUse:
DECLARE @Table      nvarchar(max),
        @EntityName nvarchar(max),
        @EntityLeaf nvarchar(max),
        @EntityCode nvarchar(10),
        @CodeRefTable_EN nvarchar(max),
        @CodeRefTable_MS nvarchar(max),
        @sql  nvarchar(max);
SET     @Table = @id -- Here I want the array values to be used somehow
SET     @EntityName = 
            (SELECT ENTITYTABLE FROM [Tobias_AX_MasterZWS_test].[dbo].[DMFENTITY] --MASTER DB NAAM
            WHERE [Tobias_AX_MasterZWS_test].[dbo].[DMFENTITY].ENTITYTYPENAME = @Table
            )
SET     @EntityLeaf = @EntityName + '_Leaf'
SET     @EntityCode = 
            (SELECT Code FROM [MDS_AX2012_ZWS].[mdm].[tbl_1_2_EN]
            WHERE [MDS_AX2012_ZWS].[mdm].[tbl_1_2_EN].[NAME] = @EntityName
            )
SET     @CodeRefTable_EN = 'tbl_'+@EntityCode +'_EN'
SET     @CodeRefTable_MS = 'tbl_'+@EntityCode +'_MS'
DECLARE @TableName_EN sysname = @CodeRefTable_EN,
        @TableName_MS sysname = @CodeRefTable_MS;


SET @sql =      N'SELECT * FROM [MDS_AX2012_ZWS].[dbo].[AxVersionTable] WHERE [MDS_AX2012_ZWS].[dbo].[AxVersionTable].EntityName ' + --change to DELETE FROM after testing
                N' = ' +
                quotename(@EntityName, '''') +
                N';';
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [MDS_AX2012_ZWS].[STG].' + quotename(@EntityLeaf) --change to DROP TABLE after testing
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [MDS_AX2012_ZWS].[MDM].' + quotename(@TableName_EN) + 'WHERE VERSION_ID <> 1337'; --change to DELETE FROM after testing
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [MDS_AX2012_ZWS].[MDM].' + quotename(@TableName_MS) + 'WHERE VERSION_ID <> 1337'; --change to DELETE FROM after testing
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [MDS_AX2012_ZWS].[MDM].' + quotename(@TableName_EN); --change to DROP TABLE after testing
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [MDS_AX2012_ZWS].[MDM].' + quotename(@TableName_MS); --change to DROP TABLE after testing
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [Tobias_AX_MasterZWS_test].[dbo].' + quotename(@EntityName); --change to TRUNCATE TABLE after testing
EXEC sp_executesql @sql;
SET @sql =      N'SELECT * FROM [Tobias_AX_MasterZWS_test].[dbo].[DMFENTITY] WHERE [Tobias_AX_MasterZWS_test].[dbo].[DMFENTITY].EntityTable ' + --change to DELETE FROM after testing
                N' = ' +
                quotename(@EntityName, '''') +
                N';';
EXEC sp_executesql @sql;

有人建议如何将迭代与过程联系起来吗？

将查询另存为存储过程，并使其遍历数组
