for ALTER TABLE, LOAD DATA).
ROW_COUNT is now assigned according to the following rules:
- In my_ok():
- for DML statements: to the number of affected rows;
- for DDL statements: to 0.
- In my_eof(): to -1 to indicate that there was a result set.
We derive this semantics from the JDBC specification, where int
java.sql.Statement.getUpdateCount() is defined to (sic) "return the
current result as an update count; if the result is a ResultSet
object or there are no more results, -1 is returned".
- In my_error(): to -1 to be compatible with the MySQL C API and
MySQL ODBC driver.
- For SIGNAL statements: to 0 per WL#2110 specification. Zero is used
since that's the "default" value of ROW_COUNT in the diagnostics area.

Fix a typo.
