[jira] Resolved: (DERBY-4255) DatabaseMetaData
getDatabaseMajorVersion() and getDatabaseMinorVersion() return software
version rather than database version
[ https://issues.apache.org/jira/browse/DERBY-4255?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kathey Marsden resolved DERBY-4255.
-----------------------------------
Resolution: Invalid
Closing Invalid. Discussion concluded that getDatabaseMajorVersion and getDatabaseMinorVersion should continue to return the product version, not the database format version. DERBY-4259 has been logged to achieve this functionality with a database property.

> Key: DERBY-4255
> URL: https://issues.apache.org/jira/browse/DERBY-4255
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.1.3.1, 10.2.2.0, 10.3.3.0, 10.4.2.0, 10.5.1.1, 10.6.0.0
> Reporter: Kathey Marsden
>
> The javadoc for
> DatabaseMetaData.getDatabaseMajorVersion() and getDatabaseMinorVersion() says they should retrieve the version number of the underlying database, so for soft upgraded databases this should be the database format version not the current software version which it currently does. getDatabaseProductVersion should continue to return the current software version.
> To reproduce create a database wombat with 10.1 with ij and then run the program below with 10.5.
> import java.sql.*;
> public class TestDBMetaDatabaseVersion {
> public static void main(String[] args) throws Exception{
> Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
> Connection conn = DriverManager.getConnection("jdbc:derby:wombat");
> DatabaseMetaData dmd = conn.getMetaData();
> System.out.println("getDatabaseMajorVersion():" + dmd.getDatabaseMajorVersion());
> System.out.println("getDatabaseMinorVersion():" + dmd.getDatabaseMinorVersion());
> System.out.println("getDatabseProductVersion():" + dmd.getDatabaseProductVersion());
>
> }
> }
> The output shows:
> getDatabaseMajorVersion():10
> getDatabaseMinorVersion():5
> getDatabseProductVersion():10.5.1.2 - (777744M)
> The first two are incorrect and should show 10.1
