The following SQL:
     C/EXEC SQL
     C+ Declare C1 cursor for
     C+ SELECT login.logid, login.logpas, login.logfnm, login.loglnm,
     C+        login.logcnm, login.logacc, login.logact, login.loglev,

     C+        ON login.logid = tpnbr.logid)
     C+        left outer join tptype
     C+        on tpnbr.tpttype = tptype.tpttype)
     C+        left outer join tpfacl

     C+        and tpnbr.tpnbr = tpfacl.tpnbr
     C+        and tpnbr.tpttype = tpfacl.tpttype)
     C+     WHERE login.logid=:UserName and login.logpas=:Password
     C+        and login.logsts='1'

     C+        and (login.logpwei<0 or
     C+            (CURRENT DATE <= DATE(logpwcd)+ logpwei days))
     C/END-EXEC

gives me this error:
                        Additional Message Information

Message ID . . . . . . :   SQL0305       Severity . . . . . . . :   30

Message . . . . :   Indicator variable required.
Cause . . . . . :   A FETCH, an embedded SELECT, a CALL or a SET or VALUES

  INTO statement has resulted in a null value, but an indicator variable
was
  not specified for host variable LSAMPLE.TPFACL.  The relative position
of
  the host variable in the INTO clause or parameter list is 33. If the
host
  variable name is *N, an SQLDA was specified.
Recovery  . . . :   Specify an indicator variable, and precompile the
program
  again.

when there is no match in TPFACL file for TPNBR.  I am guessing my
alternatives are to use null indicator variables, or have defaulting
values.  I am open for suggestions.
