SQL-Programmer tool and field%type support

From

Hi,I'm looking for PL/SQL programmer tool. I wanted to use SQL-Programmer but
itdoesn't support Postgres data base.Please can sommeone suggest me an other tool wich can replace this one orexplaine
mehow we can use SQLProgrammer with Postgres if it is possible.
 
I have an other question about the use of %type and alias in PL/SQL.  So the
excution of functions containing varibales of type maytable.field1%type
prompts parser errors.
error on the creation of the function :
create function test (int) returns maytable.field1%type as' ...
parser: parse error at or near "."

error on the excution of the function :
create function test (int) returns int as'
declare
var1 maytable.field1%type;
var2 alias for $1;  ....
parser: parse error at or near '%'
parser: parse error at or near "$1"

Please help me.Thanks.Mourad.

I don't know such tool.The documentation has some advices on tools/ways to program in
PL/pgSQL.

This syntax is not supported in PG 7.1. AFAIK, it will be supported in
PG 7.2.You can use function overloading if you need the same function to
return different types.-Roberto

What Roberto is saying is that the declaration:

DECLARE
v_field1 mytable.field1%type

is supported internal to a PL/pgSQL function, but

CREATE FUNCTION test1(int) RETURNS mytable.filed1%type 

is not.  This is because the %type declaration is supported in PL/pgSQL,
but not in Postgres SQL.

It does work in 7.2devel, however ...
