RE: embedded sql .. error check..

[CWilt@xxxxxxxxxxxx]

Additionally,

If this call is to be made multiple times you'd be better off using
parameter markers.

     c/exec sql
     c+ declare  c1 cursor for DynSqlStmt
     c/end-exec

     c                   eval      sql = 'SELECT DISTINCT prpoid '+
     c                             'FROM pmppr WHERE prhreq = '+
     c                             '?'
     c                             ' and prco < ''  090'''

     c/exec sql
     c+ Prepare DynSqlStmt from :sql
     c/end-exec

 
     c                   eval julianChar = %editc(julian:'Z')

     c/EXEC SQL OPEN C1 using julianChar
     c/END-EXEC

 

     c                   dow       1=1

     c/EXEC SQL
     c+ FETCH next from c1 INTO :po#
     c/END-EXEC
