Re: variables with SELECT statement

Just testing the regexp_string_to_array

This SQL
select description, regexp_string_to_array(description::text , E'\\s+' )
as optdesc, securitytype     from xxxxxx where type = 'B'   order by 1

produced this error:

ERROR: function regexp_string_to_array(text, text) does not exist
SQL state: 42883
Hint: No function matches the given name and argument types. You may
need to add explicit type casts.
Character: 21


Don't see the difference between the above and the example in the doc's.

Try regexp_split_to_array().

ml#FUNCTIONS-POSIX-REGEXP

SELECT regexp_split_to_array('the quick  brown    fox     jumped over
the lazy dog', E'\\s+');            regexp_split_to_array
------------------------------------------------{the,quick,brown,fox,jumped,over,the,lazy,dog}
