Remove unneeded code to get JDBC level in BrokeredConnection and
BrokeredStatement classes
------------------------------------------------------------------------------------------
Key: DERBY-3525
URL: https://issues.apache.org/jira/browse/DERBY-3525
Project: Derby
Issue Type: Improvement
Components: JDBC, Network Client
Affects Versions: 10.5.0.0
Reporter: Knut Anders Hatlen
Priority: Minor
BrokeredConnection has a method called getJDBCLevel() whose only purpose is to
provide a value that can be stored in BrokeredStatement.jdbcLevel. This field
is only used once, in BrokeredStatement.createDuplicateStatement():
if (jdbcLevel == 2)
newStatement = conn.createStatement(resultSetType,
resultSetConcurrency);
else
newStatement = conn.createStatement(resultSetType,
resultSetConcurrency,
resultSetHoldability);
Since getJDBCLevel() only returns 2 if Java version 1.3 is used, and Derby
doesn't support Java 1.3 any more, BrokeredConnection.getJDBCLevel() and
BrokeredStatement.jdbcLevel could be removed.
