Semicolons are typically used in > command line programs but are not needed when using the JDBC API. In this > case, the stray semi-colon breaks rewriteBatchedStatement support. See: > http://forums.mysql.com/read.php?39,271526,271526#msg-271526 for an example. > In my use case, rewriteBatchedStatement is very useful because it increases > the speed of inserts and reduces memory consumption. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
