Question

I’ve question to ask.

Let’s say I ‘ve 2 database table.

Table1          Table2
------          ------

id(PK)          id(FK)

column2         column2

column3         column3

What I need is to write 1 query so I can take Table1’s column2 using Table2’s id(FK).
How can I do this with just one query?

Thank you

You just need to JOIN the tables.

select t1.column2
from table1 t1
left join table2 t2
   on t1.id = t2.id
