@ -2603,22 +2603,13 @@ void ha_partition::unlock_row()
ha_berkeley.cc has a variant of how to store it intact by "packing" it
for ha_berkeley's own native storage type.
See the note for update_row() on auto_increments and timestamps. This
case also applied to write_row().
Called from item_sum.cc, item_sum.cc, sql_acl.cc, sql_insert.cc,
sql_insert.cc, sql_select.cc, sql_table.cc, sql_udf.cc, and sql_update.cc.
ADDITIONAL INFO:
Most handlers set timestamp when calling write row if any such fields
exists. Since we are calling an underlying handler we assume the´
underlying handler will assume this responsibility.
Underlying handlers will also call update_auto_increment to calculate
the new auto increment value. We will catch the call to
get_auto_increment and ensure this increment value is maintained by
only one of the underlying handlers.
We have to set timestamp fields and auto_increment fields, because those
may be used in determining which partition the row should be written to.
