- All Implemented Interfaces:
java.sql.DatabaseMetaData
,java.sql.Wrapper
public class JtdsDatabaseMetaData extends java.lang.Object implements java.sql.DatabaseMetaData
jTDS implementation of the java.sql.DatabaseMetaData interface.Implementation note:
This is basically the code from the original jTDS driver. Main changes relate to the need to support the new ResultSet implementation.
TODO: Many of the system limits need to be revised to more accurately reflect the target database constraints. In many cases limits are soft and determined by bytes per column for example. Probably more of these functions should be altered to return 0 but for now the original jTDS values are returned.
