seung hoon yoo added a comment - 2015-05-07 10:18 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.

Whether MariaDBs driver should introduce a new feature with that parameter is a good question.

seung hoon yoo added a comment - 2015-06-15 10:02 - edited 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; }
