Subj:   Re: Conditional macro execution
 
From:   Agarwal, Rachana

Vivek,

You can use coalesce function to select all rows in case null is passed as argument.

Look at the 2 different examples of macros below :-

1)

     replace macro m1( name1 char(10) ) as

     (sel * from t1 where t1.name= coalesce( :name1 , t1.name) or :name1 is null ;

     )

Or another solution below

2)

     replace macro m1( name1 char(10) ) as

     (sel * from t1 where t1.name=  :name1  or :name1 is null ;
     )

Regards,

Rachana
