I've finally taken the plunge and upgraded PgODBC from 7.03.02.00 to 8.02.04.00 ... I'm having an issue with data truncation on the uniqueidentifier type (http://gborg.postgresql.org/project/...rojdisplay.php) ...


'in ASP vbScript....

dim conn, sql, rs, newUUID
set conn = server.createobject("adodb.connection")
conn.open("Provider=MSDASQL.1;Password=pass;Persis t Security Info=True;User Id=user;Mode=ReadWrite;" & _
"Extended Properties=""DRIVER={PostgreSQL ANSI};" & _
"DATABASE=data;SERVER=10.0.0.2;PORT=5432;UID=user; PWD=pass;" & _
"SSLmode=disable;ReadOnly=0;Protocol=7.4-1;FakeOidIndex=0;ShowOidColumn=0;RowVersioning=0;" & _
"ShowSystemTables=0;ConnSettings=set+sort%5Fmem%3D 10241%3Bset+geqo%3Don%3B;Fetch=300;Socket=4096;" & _
"UnknownSizes=0;MaxVarcharSize=254;" & _
"MaxLongVarcharSize=8190;Debug=0;CommLog=0;Optimiz er=1;Ksqo=1;UseDeclareFetch=0;TextAsLongVarchar=1; " & _

"UpdatableCursors=1;DisallowPremature=0;TrueIsMinu s1=0;BI=0;ByteaAsLongVarBinary=0;UseServerSidePrep are=1;" & _
"LowerCaseIdentifier=0;XaOpt=1""")

sql = "select newid() as uuid;"

set rs = conn.execute(sql)
newUUID = rs("uuid").value

response.write ("Length : " & len(newUUID) & "<BR>" & vbcrlf)
response.write ("Type : " & vartype(newUUID) & "<BR>" & vbcrlf)
response.write ("<table border=""1"">")
for i = 1 to len(newUUID)
response.write ("<tr><td>" & asc(mid(newUUID,i,1)) & "</td><td>" & server.htmlencode(mid(newUUID,i,1)) & "</td></tr>" & vbcrlf)
next
response.write ("</table>")

rs.close
set rs = nothing
conn.close
set conn = nothing

The returned value is the correct length, but there must be a null inserted after the 16th character becasuse the return value, which is a string type, abruptly terminates at that point.

If I cast the uuid to type text, nothing gets truncated. This wasn't a problem in 7.03.02.00 ...

Could you send me directly the Mylog output ?

I seem to have found the cause.
Please try the drivers on testing for 8.2.0402 at
http://www.geocities.jp/inocchichich...dbc/index.html .
