mysql - Concatenating two tables with same column number and name -
i have 2 tables:
table_a
head1 head2 foo case1 bar case2 and table_b
head1 head2 hux case1 pix case2 ilf case1 what want create table:
head1 head2 foo case1 bar case2 hux case1 pix case2 ilf case3 namely combine them, without removing redundancy.
what's right command it? tried didn't give the desired result.
create table table_ab(head1 text, head2 text) (select * table_a) union (select * table_b)
you can omit parenthesis around union parts. also, create table ... select, don't have specify column definitons.
create table table3 select * table1 union select * table2 example @ sql fiddle.
