I've just started testing postgreSQL as a backend database for an
NT-based intranet application running on Cold Fusion.
The application will automatically create the database structure if it
does not already exist, by executing a series of CREATE TABLE statements
through the ODBC driver.
However, only the first table is being created.
Each statement is in a separate request, and any one statement will
execute, but only if it is the first. Even more puzzling is the fact
that subsequent calls do not throw an error. The first error I see is
when an attempt is made to insert data into a non-existent table.
The application has tested out fine on both MS Access and MS SQL Server.
The ODBC driver version is 6.40.0002
Code follows:
(For those not familiar with Cold Fusion, the <CFQUERY> tags specify a
distinct database call. #attributes.datasource# is a variable name
containing the DSN)
