Question

在Azure Data Warehouse中，我有Stored Procedure，它将返回SELECT命令的结果。

如何将Stored Procedure结果推送到临时表？

我尝试了以下查询，它返回了一条错误消息。

CREATE TABLE #temp
(name varchar(255), created_date datetime)
GO
INSERT INTO #temp
EXEC sp_testproc

输出讯息：

Msg 103010, Level 16, State 1, Line 3
Parse error at line: 2, column: 1: Incorrect syntax near 'EXEC'.

根据here，Azure SQL数据仓库不支持INSERT ... EXEC。但是，临时表也有不同的范围，这意味着可以在外部创建它们的存储过程中查看它们。只需在存储过程中创建临时表，就可以在存储过程执行后查看它，例如：

IF OBJECT_ID('dbo.usp_getTableNames') IS NOT NULL DROP PROC dbo.usp_getTableNames;
GO

CREATE PROC dbo.usp_getTableNames
AS

    -- Drop table if already exists
    IF OBJECT_ID('tempdb..#tables') IS NOT NULL DROP TABLE #tables;

    -- Create temp table for viewing outside stored procedure
    CREATE TABLE #tables
    (
        [object_id]     INT NOT NULL,
        name            SYSNAME NOT NULL
    )
    WITH
    (
        DISTRIBUTION = HASH([object_id]),
        HEAP
    );


    INSERT INTO #tables
    SELECT object_id, name
    FROM sys.tables;

GO

-- Run the proc
EXEC dbo.usp_getTableNames;
GO


-- The table table is still available for reading outside the scope of the stored procedure
SELECT *
FROM #tables;

DROP TABLE #tables;
GO

this文章的“模块化代码”部分提供了类似的示例。这只是一个略微不同的做事顺序。

存储过程结果存入Azure数据仓库中的临时表
