Hi,

i have one column called jobcode. this should be unique but based on branchid. i mean if branchid is different in that table it should allow same jobcode to be entered again but it should block for same branchid. if i apply unique key directly it will not allow to enter same number again even if branchid is different.

please suggest me something

thanks in advanced.

Hello,

If you are using sql server then just open table design then select Both column press right click and Choose "Set Primary Key".

Then both column will behave as you required.
