RE: idea for reading encodign format

Is possible that the problem the vesrione of the compiler?
My version 7.2 is compiled by GCC 2.95.3-5
Your version 7.2 is compiled by GCC egcs-2.91.66

Is a problem ?

OK, any ideas on the problem I mentioned?

The 7.2 system was ! ; compile d without multibyte support. In 7.3, multibyte is always on. I guess it probably doesn't matter much as it's obviously giving only useful encodings, the problem is this (on the 7.2 system):


template1=> select pg_encoding_to_char(45);
pg_encoding_to_char
---------------------
SQL_ASCII

(1

row)


template1=> select pg_encoding_to_char(450);
pg_encoding_to_char
---------------------
SQL_ASCII
(1 row)
0 D

How would the loop know when to give up and exit?

I replace this code in frmdatabase pgadmin2. I don't have this problem.

What is your result if you execute this selection ?

select pg_encoding_to_char(0)

union select pg_encoding_to_char(1)

union select pg_encoding_to_char(2)

0D
union select & nbsp; pg_encoding_to_char(3)

union select pg_encoding_to_char(4)

union select pg_encoding_to_char(5)

union select pg_encoding_to_char(6)

union select pg_encoding_to_char(7)

union select pg_encoding_to_char(8)

union select pg_encoding_to_char(9)

union select pg_encoding_to_char(10)

union select pg_encoding_to_char(11)

union select pg_encoding_to_char(12)

union select pg_encoding_to_char(13)

union select pg_encoding_to_char(14)

union select pg_encoding_to_char(15)

union select pg_encod! ing_to_ch a r(16)

union select pg_encoding_to_char(17)

union select pg_encoding_to_char(18)

0Aunion
s
elect pg_encoding_to_char(19)

union select pg_encoding_to_char(20)

union select pg_encoding_to_char(21)

My result is :

pg_encoding_to_char
---------------------

EUC_KR

ISO_8859_6

The order is not by number encoding.

Hi Frank,


Hmm, that doesn't seem to work here. For any random integervalue of X &nb! sp; & nbsp;that I try in select pg_encoding_to_char(X), I get SQL_ASCII as the result.

This is a problem I would like to fix, though I don't have time myself right now :-(

&! nbsp;&nbs p ;

for reading encodign format current version is:

'Load the Encoding Schemes
cboProperties(0).Text = "SQL_ASCII"
Set objItem = cboProperties(0).ComboItems.Add(, , "S
QL_ASCII
"
, "encoding", "encoding")
objItem.Selected = True
&n! bsp; ;

cboProperties(0).ComboItems.Add , ! &nb s p;, "UNICODE", "encoding", "encoding"

cboProperties(0).ComboItems.Add , , "WIN", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "ALT", "encoding", "encoding"

this version is a problem to custom encodign into program. For new encodign modify program to add new &n! bsp;encod i gn

For reading automatly encodign
u

ign this code : < /P>
Dim rsSQL As New Recordset

&nbs! p; & n bsp;
'Load the Encoding Schemes
bIsValid = True
X = 0
While bIsValid
Set rsSQL = frmMain.svr.Databases("template1").Execute("select pg_encoding_to_char(" & X & ")")
If &n! bsp;rsSQL . Fields(0).Value = "" T! hen b IsValid = False
