>Hello everyone,
>I would like to know how to pass a parameter to a view's "where" clause for conditions. For example, in different areas I may have different "where" clause conditions. In one instance, I may have "cField1 = 'x'" and in another instance "cField2 = 'y' .AND. !empty(cField1)". Is this possible? I had attempted the following but it did not work: "create sql view test as select * from myTable where ?x"
>then before issuing the "use test" I assigned x="cField1 = 'x'". I would appreciate any suggestions.

Others have responded to this question and I agree with all of them.

You could use an open clause

cExpr = "cField1 = 'x'"

CREATE SQL VIEW "My_view" ;
AS SELECT field_list from my_table ;
where &cExpr

This may blow up in your face though. Not having defined cExpr and trying to use the view in a form will error, all the time.
