Hello~

i think additional fix need about alias thing of column

please read : http://dev.mysql.com/doc/connector-j/en/connector-j-installing-upgrading-5-1.html

ResultSetMetaData.getColumnName() is display real column (mariadb connector/j 1.1.8ver) so
if attach parameter ( useOldAliasMetadataBehavior=true)
then ResultSetMetaData.getColumnName() need display alias column name as getColumnLabel().

(mysql connector done, mariadb connector not yet)

Like table, column alias need old behaviour

Thanks.

useOldAliasMetadataBehavior=true was backward compatibility fix for own non-JDBC compliant ConnectorJ behavior w.r.t column names, among other things. Whether MariaDBs driver should introduce a new feature with that parameter is a good question.

hi~ I just 2 row add in 1.1.9 connector gihub script u contribute
that make column label name display instead column name when useOldAliasMetadataBehavior option true

how about my idea,
and would u add this source (2 line in MySQLResultSetMetaData.java) next release 1.1.9 ver??

MySQLResultSetMetaData.java

 public String getColumnName(final int column) throws SQLException {

        String s =  getColumnInformation(column).getOriginalName();      

+        if (returnTableAlias == true)    // if useOldAliasMetadataBehavior=true then getColumnName return getCoulmnLabel

+         s =  getColumnLabel(column); 

        if ("".equals(s))  // odd things that are no columns, e.g count(*)

            s =  getColumnLabel(column);

        return s;

    }
