How can i execute a stored procedure inside another stored procedure in SQL Server? - sql

Question

I´m working with SQLServer and I have two storedprocedures
The first one:
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON
DECLARE #FECHAFIN AS datetime;
SET #FECHAFIN = #FECHAINICIO + '23:59:59.999'
-- Insert statements for procedure here
SELECT
HC.idCorrida AS Referencia,
T.part AS Parte,
T.idTrabajo AS Trabajo,
HC.cantidadFabricado AS Piezas,
HC.cantidadRechazado AS Rechazo,
CONVERT(varchar(8), HC.tiempoProduccion) AS TiempoDeProduccion,
CONVERT(varchar(8), HC.tiempoMuerto) AS TiempoMuerto,
HC.fechaInicio AS Fecha,
U.nombreUsuario AS Usuario,
MA.nombre AS NombreMaquina,
TR.nombre AS NombreTripulacion,
TXM.idTurno AS Turno,
FROM [Produccion].[HistorialCorridas] AS HC
INNER JOIN [Produccion].[Trabajos] AS T
ON HC.idTrabajo = T.idTrabajo
INNER JOIN [Administracion].[Usuarios] AS U
ON U.idUsuario = HC.idUsuario AND U.idTripulacion = #IDTRIPULACION
INNER JOIN [Administracion].[Tripulaciones] AS TR
ON U.idTripulacion = TR.idTripulacion
WHERE HC.idTurnoXMaquina = #IDTURNOXMAQUINA
AND HC.fechaInicio >= #FECHAINICIO AND HC.fechaInicio <= #FECHAFIN
GROUP BY HC.idCorrida, T.part, T.idTrabajo, HC.cantidadFabricado, HC.cantidadRechazado,
HC.tiempoProduccion, HC.tiempoMuerto, HC.fechaInicio, U.nombreUsuario, MA.nombre, TR.nombre, TXM.idTurno
END
The second one:
BEGIN
SET NOCOUNT ON
SELECT
CONVERT(VARCHAR(8), DATEADD(SECOND,SUM(DATEDIFF(SECOND, '00:00:00', TiempoMuerto)),0),114) AS TotalTiempoMuerto,
P.etiqueta AS TipoParo
FROM [Produccion].[TiemposMuertos]
INNER JOIN [Administracion].[ParosXMaquina] AS PM
ON PM.id = idParoXMaquina
INNER JOIN [Administracion].[Paros] AS P
ON P.idParo = PM.idParo
WHERE idCorrida = #IDCORRIDA
GROUP BY P.etiqueta
END
The second one receives as a parameter a field called Referencia from the first stored procedure. What I want to do, is execute the second stored procedure from the first one, passing that parameter.
How could I achieve this? Is it possible to get the result in just one query?
Thanks in advance!!!

Answer 1

To call a PROCEDURE from another PROCEDURE that returns a value as output, you must use the out keyword for the output, which may be a table or other data type.
The following two procedures are defined.
In test1 procedure, the return parameter is specified with out.
In the second procedure, the first procedure is called as follows:
DECLARE #result int
EXEC test1 #result OUTPUT
CREATE PROCEDURE test1
(#outID int output)
AS
BEGIN
SET #outID = (select top 1 ID from table1)
END
CREATE PROCEDURE test2
AS
BEGIN
BEGIN
DECLARE #result int
EXEC test1 #result OUTPUT
SELECT ID from table2 where ID = #result
END;
END
GO
EXEC test2
