Hi,<br />I can use some help with the following query please.<br /><br />Given a couple of tables I want to do a JOIN
likeoperation. Except that one of the columns might be null.<br /><br />create table T1 ( id serial, name varchar(20)
);<br/> create table T2 ( id serial, name varchar(20) );<br />create table T1_T2 ( id serial, t1_id integer not null ,
t2_idinteger ); <br /><br />Now I'd like to show a list of records from T1_T2 but reference T1 and T2 for the names
insteadof IDs. But T1_T2.t2_id might be null<br /><br />select T1_T2.id, T1.name , T2.name from T1, T2, T1_T2<br
/>whereT1_T2.t1_id = T1.id and T1_T2.t2_id = T2.id<br /><br />Basically since t2_id might be null, the condition will
failand the query will fail<br /><br />thanks<br />Medi<br />
