Description: Numeric type problem
Details:

Hi All,
I met a numeric type problem,detail :

1.Programe language:vb6
2.Postgresql ole db provider version 1.0.0.2
3.Table jack_test has only one column "salary"( type is numeric(15,2))which
has two records 2.58,3.68.

vb code:
Private Sub Command1_Click()
Dim conn As New ADODB.Connection
Dim rst As ADODB.Recordset
Dim num As Integer
Dim sql As String
On Error GoTo sqlerr
conn.ConnectionString = "Provider=PostgreSQL.1;Password=123456;User
ID=postgre;Data Source=192.168.7.1;Location=BO1;"
conn.ConnectionTimeout = 30
conn.Open
sql = "select salary from jack_test"
Set rst = CreateObject("adodb.recordset")
With rst
.ActiveConnection = conn
.CursorLocation = adUseClient
.CursorType = adOpenKeyset
.Open sql
While Not .EOF
MsgBox (.Fields("salary"))
rst.MoveNext
Wend
End With
Exit Sub
sqlerr:
MsgBox (Err.Description)
End Sub

When the CursorLocation set to adUseClient results:2,3,
the precision lost.When set to adUseServer resuls:2.58,3.68(right).Is the
problem cause by the ole provider?

Regards,
Jack
