Re: SQL SUBSTRING

Is #LEN defined as (from the SQL manual) 'a binary integer in the range 0
to n'?

The following worked for me:

D #LEN            S              5B 0
D CNTHLD          S              5P 0
D #ID             S              6A

C                   Eval      #len=6
C                   Eval      #id='81.001'
C/EXEC SQL
C+ SELECT COUNT(*) INTO :cnthld FROM ROB/aaakey
C+ where substr(loc,1,:#LEN)=:#ID
C/END-EXEC

C     cnthld        dsply

C                   Eval      *inlr=*on

i need to do a substring in SQL extracting a field of varying size.  I am
pulling this from a flat file.  I can get it to work if i specify an actual
length like this.

C+ SELECT COUNT(*) INTO :CNTHLD FROM MIKELIB/PIFCORP
C+ WHERE SUBSTR(PIFLD,1,:5) =  :#ID

HOWEVER, the length of the substring is of varying length

i have tried to do something like this

C+ SELECT COUNT(*) INTO :CNTHLD FROM MIKELIB/PIFCORP
C+ WHERE SUBSTR(PIFLD,1,:#LEN) =  :#ID

but it doesn't like the variable for the third parm.

Does anyone know how i can accomplish this.

thanks

mike
