Hi,

I have MRE report with one web page to call a Fex procedure.
The web page will transfer user selected date into the fex procedure.

Fex code: (simplfied example)
=======================
SET SQLENGINE=SQLORA
SQL SET SERVER databaseserver
SQL
select * from employ_table
where hire_date = &p_date
;
TABLE ON TABLE HOLD AS SQLtemp
END
-RUN
-*

=======================

Athough WebFOCUS tansfered the &p_date into the fex code,
But this variable is not replaced with its value in SQL part.

Would anyone tell me a way to let the &p_date variable to be replaced with its value before the SQL query is sent to Database?

We need to use SQL pass through, becasue the real SQL query and datamodel is very complicate.


Thanks,
William Zhu

Sorry for the above question. It's not an issue.

Actually, the code works.

WebFCOUS will replace the variable with its value in SQL query part.

Thanks,

William,

It really depends on what the default display of a date is. In our database (Oracle), the default display is mmm-dd-yyyy (i.e. JAN-01-2009). So we have to use the Oracle TO_DATE function as in:
WHERE HIRE_DATE = TO_DATE(&P_DATE,'YYYYMMDD')

You also have to be sure that the field contains just a date, that is, the time portion is set to midnight, otherwise, you will get just those records where the time portion is midnight. This is why we use the following:
-SET &BEGDT=20080317;
-SET &ENDDT=AYMD(&BEGDT,1,'I8YYMD');
.
.
WHERE HIRE_DATE >= TO_DATE(&BEGDT,'YYYYMMDD')
  AND HIRE_DATE <  TO_DATE(&ENDDT,'YYYYMMDD')
.
.
