mysql - After I Join with same table twice then how to call value with same column name in WHERE clause? -
i'll start example:
*table1* id phonenumber1 phonenumber2 *table2* phonenumber someotherfield select * table1 t1 inner join table2 t2 on t2.phonenumber = t1.phonenumber1 inner join table2 t3 on t3.phonenumber = t1.phonenumber2 -- here question how call same column have same name? -- want clause below: someotherfield(from first table2) = someotherfield(from second table2)
the example below question, asking different things: what's best way join on same table twice?
where t2.someotherfield = t1.someotherfield
