Hello, A new question has been asked in "Client Libraries" by tommy_pham_g. Please answer it at http://mariadb.com/kb/en/resultsetmetadata-getcolumnclassname-accuracy-for-j... as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi folks, I'm having problems getting the getColumnClassName to return the correct information. I have a sample table: CREATE TABLE `datatypes` ( `mariadb_binary` binary(8) NULL, `mariadb_blob` blob NULL, `mariadb_boolean` tinyint(1) NULL, `mariadb_varbinary` varbinary(16) NULL, `mariadb_varchar` varchar(5) CHARACTER SET utf8 NULL, UNIQUE KEY `mariadb_serial` (`mariadb_serial`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; The ResultSetMetaData is not returning accurate GetColumnClassName information for some of the above columns: [INFO ] 2015-03-02 09:26:52.905 [main] c.d.d.AppDbTest.main - getColumnName mariadb_binary | getColumnLabel mariadb_binary. getColumnClassName [B. getColumnDisplaySize 8. getColumnType -2. getColumnTypeName BINARY. [INFO ] 2015-03-02 09:26:52.905 [main] c.d.d.AppDbTest.main - getColumnName mariadb_blob | getColumnLabel mariadb_blob. getColumnClassName [B. getColumnDisplaySize 65535. getColumnType -4. getColumnTypeName BLOB. [INFO ] 2015-03-02 09:26:52.905 [main] c.d.d.AppDbTest.main - getColumnName mariadb_boolean | getColumnLabel mariadb_boolean. getColumnClassName java.lang.Boolean. getColumnDisplaySize 1. getColumnType -7. getColumnTypeName TINYINT. getPrecision 1. [INFO ] 2015-03-02 09:26:52.998 [main] c.d.d.AppDbTest.main - getColumnName mariadb_varbinary | getColumnLabel mariadb_varbinary. getColumnClassName [B. getColumnDisplaySize 16. getColumnType -3. getColumnTypeName VARBINARY. getPrecision 16. [INFO ] 2015-03-02 09:26:53.014 [main] c.d.d.AppDbTest.main - getColumnName mariadb_varchar | getColumnLabel mariadb_varchar. getColumnClassName java.lang.String. getColumnDisplaySize 5. getColumnType 12. getColumnTypeName VARCHAR. getPrecision 5. Is the above by design? Is it bug within JDBC spec? I'm using MariaDB JDBC version 1.1.8.
