Help with correlated sub query in select list

>The  query runs fine when I remove the subquery in the select list.  
what's the error message, resp problem result?

The message I get from the Pervasive SQL Editor is

Some error(s) encountered while executing SQL statement(script).

Not very helpful.

you can't have SELECT statement in the select vaules


use the following.

SELECT
  B.BKIC_PROD_CODE Part_Num,
  B.BKIC_PROD_DESC Description,
  W.MTWO_WIP_COMQTY COMQTY,
  W.MTWO_WIP_SQTY SQTY,
  W.MTWO_WIP_COMQTY / W.MTWO_WIP_SQTY YIELD,
  W.MTWO_WIP_ELABOR ELABOR,
  W.MTWO_WIP_ALABOR ALABOR, W.MTWO_WIP_ALABOR / W.MTWO_WIP_SQTY LAB_Per_Pc,
  SUM(WO.MTWORO_ESTHRS)
    FROM
    WORKOUTOLD WO
    WHERE WO.MTWORO_WOPRE = W.MTWO_WIP_WOPRE AND WO.MTWORO_WOSUF = W.MTWO_WIP_WOSUF),
  W.MTWO_WIP_AFIN AFINISH,
  W.MTWO_WIP_WOPRE WOPRE
FROM  
  BKICMSTR B INNER JOIN WORKORD W ON B.BKIC_PROD_CODE=W.MTWO_WIP_CODE
WHERE
  W.MTWO_WIP_STATUS='C' AND
  W.MTWO_WIP_AFIN>='2003-03-01' AND
  W.MTWO_WIP_AFIN<='2006-03-29' AND
  B.BKIC_PROD_CODE LIKE '10275%'
ORDER BY
  B.BKIC_PROD_CLASS,
  B.BKIC_PROD_CODE

you can re-write it to

SELECT
  B.BKIC_PROD_CODE Part_Num,
  B.BKIC_PROD_DESC Description,
  W.MTWO_WIP_COMQTY COMQTY,
  W.MTWO_WIP_SQTY SQTY,
  W.MTWO_WIP_COMQTY / W.MTWO_WIP_SQTY YIELD,
  W.MTWO_WIP_ELABOR ELABOR,
  W.MTWO_WIP_ALABOR ALABOR, W.MTWO_WIP_ALABOR / W.MTWO_WIP_SQTY LAB_Per_Pc,
  WO.tot_estimated_hours,
  W.MTWO_WIP_AFIN AFINISH,
  W.MTWO_WIP_WOPRE WOPRE
FROM  
  BKICMSTR B INNER JOIN WORKORD W ON B.BKIC_PROD_CODE=W.MTWO_WIP_CODE
left outer join
(
   SELECT SUM(MTWORO_ESTHRS) as tot_estimated_hours, MTWORO_WOPRE, MTWORO_WOSUF
   FROM WORKOUTOLD
   group by MTWORO_WOPRE, MTWORO_WOSUF
) as WO on
WO.MTWORO_WOPRE = W.MTWO_WIP_WOPRE AND WO.MTWORO_WOSUF = W.MTWO_WIP_WOSUF
WHERE
  W.MTWO_WIP_STATUS='C' AND
  W.MTWO_WIP_AFIN>='2003-03-01' AND
  W.MTWO_WIP_AFIN<='2006-03-29' AND
  B.BKIC_PROD_CODE LIKE '10275%'
ORDER BY
  B.BKIC_PROD_CLASS,
  B.BKIC_PROD_CODE


OR, you could just try assigning a column name to the subquery, which your editor may require, your query looks like it would run in MS SQL Query Analyser.  I don't know the datatype of MTWORO_ESTHRS but I assume you tested the sub-query separately and it is bringing back the correct summed value.

'tot_estimated_hours' = (SELECT SUM(WO.MTWORO_ESTHRS)
    FROM
    WORKOUTOLD WO
    WHERE WO.MTWORO_WOPRE = W.MTWO_WIP_WOPRE AND WO.MTWORO_WOSUF = W.MTWO_WIP_WOSUF),

Tom,

I've tried both of your suggestions, but still no luck.  I am wondering if Pervasive 2000i cannot handle a subquery like this.

That query does run, but the entire query does not.

Thanks for the help.
