Summary
Sometimes you want to know where the database column types values are obtained when looking at the database results auto-generated code, but there is no easy way of determining that information by looking at the database results code. This is because the database column types are defined as field types in the database definition. This blog lists those definitions.
More Information
There are two different places where the column/field types will be listed:
- In the ASP code =
fp_sColTypes
- In the WEBBOT code =
s-columntypes
Below is a list of the column/field types in an Access database:
