I use host variables in PL1 program for Static SQL:
Code:

  Update table
   set COL1 = :VAL1, STATUS = :STATUS
   WHERE COL3 = VAL3

Someone told me it doesn't matter if the value is a contant (e.g. STATUS is always 'S'):
Code:

  Update table
   set COL1 = :VAL1, STATUS = 'S'
   WHERE COL3 = VAL3

Is it true?

danm,

Did you assume that you always need host variables? You can have constants. The flexibility of using the host variables is to pass dynamic values. If you think the value does not change then use hard coded values.

Yes, in this case it is a constant. Thanks.
