Endigi qilishim kerak bo’lgan ish:

Table A va B.

A table da 50 million atrofida row.
B table da 26 milliard atrofida row.

A tabledagi X columnni B tabledagi X column yordamida to’ldirishim kerak.

A - aID
B - bID

Menda C mapping table bor, yani (aID, bID).

Qiziq task.

Tugatsam qanday qilganimni aytaman.
