Give us full part numbers for both chips, or better yet give us links to their data sheets.

Also use a meaningful title for you posts.

The L293 has four push-pull output so it can sink (provide gnd) or source current (provide positive supply) so it can be used for unipolar or bipolar motors
ULN2003 (if this is what you are referring to) can only sink current (provide gnd) because the outputs are open collector, it can only drive unipolar motors.
