Question

我需要创建一个存储过程，它将返回一个代码列表，然后我需要调用另一个存储过程来逐个查看每个代码。

我该怎么做？

CREATE PROCEDURE [dbo].[paBltBuscarBoletasASA] @id_Asa int  
AS
DECLARE @Query int, @Contador int 
SET @Contador = 0
BEGIN
      SET NOCOUNT ON;  
      SET @Query = (
                SELECT 
                    localizacion.c_Fk_IdBoleta
                FROM 
                    Blt_Boleta as boleta, Fnc_Localizacion as localizacion
                WHERE 
                    boleta.c_Pk_IdBoleta = localizacion.c_Fk_IdBoleta AND
                    localizacion.si_CodAsa = @id_Asa) //This query give the list of Codes. For example 45550711, 40480711, 80110711... etc

    exec dbo.paBltMarcarErroresBoleta @Query //And here I need send one by one that list of Codes
END

Answer 1

您可以考虑添加标量函数并在查询中调用它，例如：

SELECT 
    localizacion.c_Fk_IdBoleta,
    dbo.checkCode(localizacion.c_Fk_IdBoleta) as Check
FROM 
    Blt_Boleta as boleta, Fnc_Localizacion as localizacion
WHERE 
    boleta.c_Pk_IdBoleta = localizacion.c_Fk_IdBoleta AND
    localizacion.si_CodAsa = @id_Asa

Answer 2

为您设置的等于@Query的查询声明CURSOR，然后在WHILE @@ FETCH_STATUS = 0循环中将每个后续值插入变量。然后将@Query变量传递给您当前正在执行的第二个存储过程。这是一个例子：

DECLARE myCursor CURSOR FOR
SELECT localizacion.c_Fk_IdBoleta
FROM Blt_Boleta as boleta, Fnc_Localizacion as localizacion
WHERE boleta.c_Pk_IdBoleta = localizacion.c_Fk_IdBoleta AND 
localizacion.si_CodAsa = @id_Asa

OPEN myCursor

FETCH NEXT FROM myCursor INTO @Query

WHILE @@FETCH_STATUS = 0
BEGIN
    exec dbo.paBltMarcarErroresBoleta @Query
    //do additional processing

FETCH NEXT FROM myCursor INTO @Query
END

CLOSE myCursor
DEALLOCATE myCursor
