MariaDB 10.11
Description
According to JDBC document:
_If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
A value of EXECUTE_FAILED – indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails_
In the test case below, MariaDB connector insert '2006-04-01', '2010-10-02', '2019-04-11' into table t1, however, e.getUpdateCounts() returns 1, 1, -2(SUCCESS_NO_INFO).
I think the expected returned results are 1, -3(EXECUTE_FAILED), 1, because the second batch insert failed and the third insert executed successfully and MySQL connector returns 1, -3, 1 as I expected.
