[jira] Resolved: (DERBY-3212) isNullable columns in ResultSet from
DatabaseMetaData.getColumnPrivileges() and getTablePrivileges() are off
[ https://issues.apache.org/jira/browse/DERBY-3212?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Myrna van Lunteren resolved DERBY-3212.
---------------------------------------
Resolution: Invalid
I'm rethinking how the isNullable column is supposed to work. I now think it needs to be correct for Derby - and in Derby, TABLE_SCHEM cannot be null.
Marking as invalid.

> Key: DERBY-3212
> URL: https://issues.apache.org/jira/browse/DERBY-3212
> Project: Derby
> Issue Type: Bug
> Reporter: Myrna van Lunteren
>
> Consider code like the following:
> DatabaseMetaData dmd = conn.getMetaData();
> ResultSet rs = dmd.getTablePrivileges(null,null,null);
> // or :
> // ResultSet rs = dmd.getColumnPrivileges(null, null, "", null);
> ResultSetMetaData rsmd = rs.getMetaData();
> int actualCols = rsmd.getColumnCount();
> for (int i = 0; i < actualCols; i++)
> {
> System.out.print("getColumnName: " + rsmd.getColumnName(i+1) + ", isNullable: ");
> System.out.println(rsmd.isNullable(i+1));
> }
> With Derby versions before 10.2.1.6, this would return true for all columns, presumably, because lacking support for grant/revoke.
> As of Derby 10.2.1.6, the following is returned:
> getTablePrivileges:
> TABLE_CAT: true, TABLE_SCHEM: false,TABLE_NAME: false,
> GRANTOR: true, GRANTEE: true,PRIVILEGE: true,IS_GRANTABLE: true
> getColumnPrivileges:
> TABLE_CAT: true, TABLE_SCHEM: false,TABLE_NAME: false,COLUMN_NAME:false,
> GRANTOR: true, GRANTEE: true,PRIVILEGE: true,IS_GRANTABLE: true
> However, the API suggests that TABLE_NAME is allowed to be null.
> Also, it suggests by not mentioning null, that GRANTEE and PRIVILEGE may not be null.
