Hi all,
I am using the PostGIS to do research. Here I think that I found a bug with=
PostGreSQL / PostGIS.
PostgreSQL 7.1.3/ PostGIS 0.6.2
There is a function called "Astext" in PostGIS, defined as below.
-- Function: astext(geometry)
CREATE FUNCTION "astext"("geometry") RETURNS "text" AS 'astext_geometry=
' LANGUAGE 'C' WITH (ISSTRICT);
When I used this function to return a geometry column, everything is OK if =
the result was less than 8190.
I used the ODBC to get the ADO RecordSet. The DefinedSize of the field "as=
text" is 8190.=20=20
Does this the PostgreSQL's ODBC problem? If the ODBC can not get the field=
's size, would it give the size of 8190?
Or this is the PostGIS's problem?
Best regards,
Tony
