Обсуждение: Postgres Array Traversing

Hallo All Frnds,

           I have to add an array in my table. and to update the array in a Procedure called by the trigger.

        In my case Like the Elements of the array are {1,2,5}  now i have to update it to {1,2,5,7} . I.e., Keeping the previous record as such and appending the new elements.

Please reply at the urgent basis..............

 Thanks in Advance......

According to the manual
(http://www.postgresql.org/docs/current/static/arrays.html#AEN5830) this
should work:


UPDATE example_table SET an_array_column = an_array_column || 7 WHERE
a_key_column = <value>;



P.S. This questions is probably more appropriate for the "pgsql-sql" list.
