Calling a Stored Procedure Passing and Receiving a Date

The DataFlex date format isn't compatible with MS SQL. You must change the way an argument is passed and/or is received.

Take a look at this sample program. You may see that the variable is declared as a string, but should be date. I'm changing the date format before call stored procedure:

 

//SAMPLE PROGRAM //

#include mertech.inc

//

//CREATE PROCEDURE TEST @@dDateIN DATETIME, @@dDateOUT DATETIME OUTPUT //AS

//    SELECT @@dDateOUT = DATEADD(dd,40,@@dDateIN)

//GO

//

string dDateIN    //both variables should be date but...

string dDateOUT   //

SET_ATTRIBUTE DF_DATE_FORMAT TO DF_DATE_USA

sysdate4 dDateIN

//changing to format yyyy-mm-dd

move ((mid(dDateIN,4,7)) + "-" + (mid(dDateIN,2,1)) + "-" +

(mid(dDateIN, 2,4))) to dDateIN

move dDateIN to dDateOUT

showIn "Arguments:"

showIn "   dDateIN =" dDateIN

showIn "   dDateOUT=" dDateOUT

login "localhost" "sa" "xxx" "SQL_DRV"

CALL_SQLSERVER_PROCEDURE "test.dbo.TEST" PASSING dDateIN dDateOUT SQLOUT

showIn "Returns:"

showIn "   dDateOUT = " dDateOUT

showIn

showIn "Done!"

inkey strlen

abort

//END OF SAMPLE //
