Changes in MySQL Connector/J 5.1.26 (2013-08-01)

Functionality Added or Changed

  • Added a toString() method to the PreparedStatementWrapper class to help debug prepared statements. (Bug #42267, Bug #11751418)

Bugs Fixed

  • An out of memory error occurred when the compression protocol was enabled with the connection option useCompression=true. This fix stops the memory leak that caused the error by making sure that CompressedInputStream releases its reference to the connection object when the input stream closes. (Bug #68400, Bug #16478043)

  • The results returned by the method DatabaseMetaData.getIndexInfo() were not sorted in the order described in the JDBC specification (NON_UNIQUE, TYPE, INDEX_NAME, and ORDINAL_POSITION). (Bug #68098, Bug #16224299)

  • DatabaseMetaData.getColumns() threw an MySQLSyntaxErrorException if the schema contains tables with ANSI quoted names with leading and trailing back quotes (`). When those names were passed as parameters in unquoted form, Connector/J treated them as quoted because of the back quotes, and thus the error. This fix adds the behavior that when the connection property pedantic was set to true, methods like DatabaseMetaData.getColumns() treat all parameters as unquoted. (Bug #65871, Bug #14598704)

  • Connector/J silently ignored calls to ResultSet.updateRow when the cursor was on the insert row. This fix ensures that an SQLException is thrown with those calls, as described in the JDBC specification. (Bug #45757, Bug #11754192)
