MySQL Connector/J 5.1 Release Notes
Backported authentication changes for 4.1.1 and newer from 3.1 branch. (Bug #1247)
Added property to “clobber” streaming results, by
setting the clobberStreamingResults
property
to true
(the default is
false
). This will cause a
“streaming” ResultSet
to be
automatically closed, and any outstanding data still streaming
from the server to be discarded if another query is executed
before all the data has been read from the server.
(Bug #1247)
Added com.mysql.jdbc.util.BaseBugReport
to
help creation of testcases for bug reports.
(Bug #1247)
ResultSet.get/setString
mashing char 127.
(Bug #1247)
Made databaseName
,
portNumber
, and serverName
optional parameters for
MysqlDataSourceFactory
.
(Bug #1246)
Optimized CLOB.setChracterStream()
.
(Bug #1131)
Fixed CLOB.truncate()
.
(Bug #1130)
Faster date handling code in ResultSet
and
PreparedStatement

Fixed deadlock issue with
Statement.setMaxRows()
.
(Bug #1099)
DatabaseMetaData.getColumns()
getting
confused about the keyword “set” in character
columns.
(Bug #1099)
Don't fire connection closed events when closing pooled
connections, or on
PooledConnection.getConnection()
with already
open connections.
(Bug #884)
Clip +/- INF (to smallest and largest representative values for
the type in MySQL) and NaN (to 0) for
setDouble
/setFloat()
, and
issue a warning on the statement when the server does not
support +/- INF or NaN.
(Bug #884)
When emptying input stream of unused rows for
“streaming” result sets, have the current thread
yield()
every 100 rows to not monopolize CPU
time.
(Bug #879)
Double-escaping of '\'
when charset is SJIS
or GBK and '\'
appears in nonescaped input.
(Bug #879)
Issue exception on
ResultSet.get
on empty result set (wasn't caught in some cases).
(Bug #848)XXX
()
Fixed regression in large split-packet handling. (Bug #848)
Don't hide messages from exceptions thrown in I/O layers. (Bug #848)
Better diagnostic error messages in exceptions for “streaming” result sets. (Bug #848)
Don't change timestamp TZ twice if
useTimezone==true
.
(Bug #774)
Fixed test for end of buffer in
Buffer.readString()
.
The insertRow
in an
UpdatableResultSet
is now loaded with the
default column values when moveToInsertRow()
is called.
(Bug #688)
Don't wrap SQLExceptions
in
RowDataDynamic
.
(Bug #688)
Don't try and reset isolation level on reconnect if MySQL doesn't support them. (Bug #688)
Change default statement type/concurrency to
TYPE_FORWARD_ONLY
and
CONCUR_READ_ONLY
(spec compliance).
(Bug #688)
DatabaseMetaData.getColumns()
wasn't
returning NULL
for default values that are
specified as NULL
.
(Bug #688)
Fix UpdatableResultSet
to return values for
get
when on
insert row.
(Bug #675)XXX
()
Support InnoDB
constraint names when
extracting foreign key information in
DatabaseMetaData
(implementing ideas from
Parwinder Sekhon).
(Bug #664, Bug #517)
Backported 4.1 protocol changes from 3.1 branch (server-side SQL states, new field information, larger client capability flags, connect-with-database, and so forth). (Bug #664, Bug #517)
refreshRow
didn't work when primary key
values contained values that needed to be escaped (they ended up
being doubly escaped).
(Bug #661)
Fixed Statement
and
PreparedStatement
issuing bogus queries when
setMaxRows()
had been used and a
LIMIT
clause was present in the query.
(Bug #496)
Fixed ResultSet.previous()
behavior to move
current position to before result set when on first row of
result set.
