  || <<Icon(checkmark.png)>> ||'''Connection.setNetworkTimeout(Executor)'''||Optional
new method. Sets the client timeout.||Throw SQLFeatureNotSupportedException.||Small||Rick||
  || <<Icon(checkmark.png)>> ||'''Connection.setSchema(String)'''||Mandatory new
method. Sets the name of the session's schema.||Add to JSR 169 implementation.||Small||Rick||
  || <<Icon(checkmark.png)>> ||'''Connection.setTypeMap(Map)'''||Spec clarification.||No
action needed.||None||-||
- || <<Icon(angry.png)>> ||'''DBMD.generatedKeyAlwaysReturned()'''||Mandatory
new method. Reports whether Statement.getGeneratedKeys() always returns a ResultSet even after
Statement.execute(String query, String[] columnNames) is called with columnNames that are
not identity columns.||Embedded Derby throws an exception if you call execute(String,String[])
with columnNames that are not identity columns, so the return value of getGeneracase, getGeneratedKeys()
returns a ResultSet with generated values. Note that Derby only allows you to define one identity
column per table. Because of the network behavior, I think that DBMD.generatedKeyAlwaysReturned()
should return true.||Small||Rick||

method. New field reports whether a column is generated as defined by the SQL Standard, part
2, section 4.14.8. These are columns defined by generation clauses built out of deterministic
expressions involving other columns in the row. These are what Derby call generaated colmns||Add
this field to the metadata query.||Small||Rick||

can throw SQLFeatureNotSupportedException.||Small||-||
