toString() method to the
PreparedStatementWrapper class to help debug
(Bug #42267, Bug #11751418)
An out of memory error occured 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
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.
