 Question and Answer Database

     FAQ: FAQ4667B - Invalid Field Type when creating ODBC DataSource
Category: Database (ODBC)
Platform: All Windows
 Product: All-CBuilder,   BC++5.x,   C++Builder1.0,   C++Builder3.x,   C++Builder4.x,   Delphi2.x,   Delphi3.x,   Delphi4.x,   VdBase7.x,   

Question:

I'm using BatchMove to create a table in an ODBC DataSource. How come I'm getting the error "Invalid Field Type"?


Answer:

This error occurs  for ODBC drivers where SQLGetTypeInfo(SQL_DOUBLE) returns a result set. In this case, the result is 
float is attempted to be created on the DataSource even though the DataSource does not support floats. A clasic example of
this is Microsoft or Oracle's ODBC driver for Oracle.

There two possible solutions:
1. Use the Native driver (SQL Links) driver for the Database if one exists
2. Create the table yourself and use BatchAppend instead of BatchCopy.
