Hi andrus,
The type of data that i use in a ref cursor is NUMBER(8)(but NUMBER(x) where x is any number or NUMBER without precision definition... give the same problem).
here the info:
- Oracle is 8.1.7.4:
ResultSetMetadata.getColumnClassName(int) --> java.math.BigDecimal
ResultSetMetadata.getScale(int) --> 0
ResultSetMetadata.getPrecision(int) --> 0
ResultSetMetadata.getColumnTypeName(int) --> NUMBER
ResultSetMetadata.getColumnType(int) --> 2
- Oralce 9:
ResultSetMetadata.getColumnClassName(int) --> java.math.BigDecimal
ResultSetMetadata.getScale(int) --> -127
ResultSetMetadata.getPrecision(int) --> 0
ResultSetMetadata.getColumnTypeName(int) --> NUMBER
ResultSetMetadata.getColumnType(int) --> 2
Thank's
Davide

Davide,
Unfortunately I don't have Oracle 8i to test it (only 9i), so could
you obtain the following information from ResultSetMetadata for the
ref cursor (via debugger or good old System.out.println()) and send
it to me:
ResultSetMetadata.getColumnClassName(int)
ResultSetMetadata.getScale(int) // this one you posted already
ResultSetMetadata.getPrecision(int)
This information should help us to patch it in the Oracle adapter.
