Getting the returned set of a MSSQL stored procedure

Hi everyone,

I'm having issues getting a return value from a stored procedure on MSSQL. Here's my SQL code:

ALTER PROCEDURE [dbo].[createEmployeeShift]
(
@employeeID varchar(38),
@equipmentID varchar(38)
)
AS

DECLARE @ID uniqueidentifier = NEWID()

INSERT INTO dbo.EmployeeShift VALUES(@ID,@employeeID,GETDATE(),NULL,@equipmentID)

SELECT @ID AS ID


When I run this stored procedure in MSSQL Management Studio, the stored procedure returns the generated ID as normal. However, when I do the same query and I do HReadFirst in WinDev, it says the data source has not been initialized. I'm kinda lost because I've had this kind of stored procedure work great before, but I can't get this one to work. Here's my WinDev code:

sQuery is string
dsData is Data Source

sQuery = "EXEC dbo.createEmployeeShift '" + sEmployeeID + "', '" + sEquipmentID + "'"

IF HExecuteSQLQuery(dsData,gctSQLConnection,hQueryWithoutCorrection,sQuery) THEN
IF HReadFirst(dsData) THEN
gsShiftID = dsData.ID

EDT_ShiftStartTime = SysDateTime()

END
END


Does anyone has an idea on why I'm unable to get the ID from the stored procedure into WinDev?
Thanks in advance.

Hi Dev,
I never tried with MSSQL, but I use select from store procedure with FirebirdSQL and I use this query definition:

sQuery="SELECT valret1, valret2, valretx FROM mystoredprocedure(param1, param2, paramx)"
hexecutesqlquery(...)
...

I hope this help

Bye

Thanks for the reply Andrea but unfortunately this syntax does not work in MSSQL. However I was able to make it work. :)

I had to change one line in my stored procedure from this:
INSERT INTO dbo.EmployeeShift VALUES(@ID,@employeeID,GETDATE(),NULL,@equipmentID)

to this:
INSERT INTO dbo.EmployeeShift OUTPUT INSERTED.ID VALUES(@ID,@employeeID,GETDATE(),NULL,@equipmentID)


And now it works great.

Do this way works fine
i use MSSQLserver with windev using Native conector

//// Pega Qt Usuarios Conectados no Banco de Dados // get number Of user connected in DATABASE
// DEC is name of my connection

MyProcedure is data source


MyProcedure.QtUsuarios = 0

IF not HExecuteSQLQuery(MyProcedure, "Dec", hQueryWithoutCorrection, "Dec_GetQtUsuarios @QtUsuarios out " ) THEN
Error(HErrorInfo())
EndProgram()
ELSE
wsge_QtConexoes = MyProcedure.QtUsuarios
END
HCancelDeclaration(MyProcedure) // libera da memoria
