Can you add a WHERE CLAUSE variable to an Oracle query. I have 2 variables that I would like to add to a query and I wanted to know can this be done.
I know you can add it to the TABLE OUT, but I would like to add it earlier in the query.

ENGINE SQLORA SET CONNECTION_ATTRIBUTES EJSWAR
SQL SQLORA
select distinct INCIDENT_SUPPLEMENTS.APPROVAL_DATE, INCIDENTS.INC_REPORT_NUMBER,
INCIDENT_SUPPLEMENTS.CREATOR_ID, INCIDENT_TYPE_CODES.DESCRIPTION, OFFENSES.OFFNSE_CD_OFFENSE_STATUS_CODE,
INCIDENT_SUPPLEMENTS.ISC_STATUS_CODE, INCIDENTS.INCIDENT_ID, INCIDENTS.ITC_CODE,
OFFENSES.INC_INCIDENT_ID, EMPLOYEES.LOGIN_ID, EMP_SERVICE_HISTORIES.EJS_EMP_ID, EMPLOYEES.EJS_EMP_ID,
EMP_SERVICE_HISTORIES.SRV_ASSIGN_CODE , EMPLOYEES.OFFICER_ID,OFFICERS.CAD_EMP_ID

Solved the WHERE CLAUSE has to be added to the TABLE FILE

That's not true. You can define entire WHERE clauses in a variable and have the variable part of your SQL.

For optimal performance you want to have your DB do most of the work to bring back the least amount of results to your server to process.


Here's an example.


 
-SET &WhereEmpNum = IF '&WhereEmpNum.EVAL' EQ '' THEN '' ELSE  'AND EMPLOYEE_NBR = ' | '''' | '&WhereEmpNum.EVAL' | '''';
-SET &WhereSite = IF '&WhereStore.EVAL' EQ '' THEN '' ELSE  'AND STORE = ' | '''' |  '&WhereStore.EVAL' | '''';
-TYPE WhereSite =(&WhereSite);
-TYPE WhereEmpNum =(&WhereEmpNum);


-INCLUDE hr_shared_sqlora
SQL
SELECT
    EMPLOYEE_NBR,
    NAME,
    JOBCODE,
    EARN_CODE,
    ATTEND_DATE,
    EARNS_END_DT,
    PAY_END_DT,
    PAY_END_DT + 5 AS ORA_PAY_END,
    PUNCH_TIME_IN,
    PUNCH_TIME_OUT,
    UPDATED_BY,
    UPDATE_DTTM,
    HOURS_QTY,
    STORE,
    CAST(COST_CENTRE AS CHAR(10)) AS COST_CENTRE,
    TL_SOURCE,
    SEQ_NBR,
    PAYROLL_SOURCE
    FROM TPDATA.TABLENAME
   WHERE TL_SOURCE IN ( 'T', 'A')
    AND BRAND = 'WEN'
    AND PAY_END_DT IN
         (SELECT DISTINCT PAY_END_DT
           FROM TPDATA.TABLENAME
            WHERE ATTEND_DATE BETWEEN '&BegDate3' AND '&EndDate3'
             AND TL_SOURCE IN ( 'T', 'A')
             AND BRAND = 'WEN'
           &WhereEmpNum
           &WhereSite
          )
&WhereEmpNum
&WhereSite
ORDER BY EMPLOYEE_NBR, ATTEND_DATE, SEQ_NBR
;
TABLE
ON TABLE HOLD AS PNCHPULL FORMAT ALPHA
END
-RUN

You can add the variable right where you tried to do just that. Didn't that work? Of course, you would need to use SQL syntax for your condition and not FOCUS syntax.

Any problem you apparently encountered in doing so is most likely due to your use of .EVAL where you just want variable substitution.

As people in many programming languages chant: ".EVAL is evil!".

That's probably no less true for dialog manager.

EVAL is definitely a good candidate for SQL injection, especially in the scenario of pass-through SQL (as is the case here). For example, someone might just send the string '1 OR 1 IN (DELETE FROM EMPLOYEES)' as a value, which then becomes part of the SQL query after evaluation.

Perfect. Thank you for the heads up.
