Raised by: @sevenFH
Steps:

1. Insert data to E-R sub-table: insert into district (d_w_id, number, name) values (001,2,'aaa'),(002,3,'bbb');
2. Got error: ERROR 1064 (HY000): ChildTable multi insert not provided

I have the same problem.
E-R childTable: insert into table ('column1','column2','column3') values (1,1,1),(2,2,2);
error: err: ChildTable multi insert not provided

I would like to be able to provide multi inserts.
