Simple Sql Conditional Select
I have a table of the following type:
int Linkid
int LinkType
datetime LinkChangeddate
datetime LinkCheckeddate
How can I write a stored procedure which selects rows based on LinkType's Value.
For each row, it is returned if:
a. If Linktype = 1 and Today-LinkCheckeddate > 3 days
b. If Linktype = 2 and Today-LinkCheckeddate > 7 days
b. If Linktype = 3 and LinkChangeddate>LinkChecke
Thanks!

Oops. Error on my sample to execute it. Instead use:
EXEC up_LinkCheckDate 1
EXEC up_LinkCheckDate 2
or
EXEC up_LinkCheckDate 3
EXEC up_LinkCheckDate 1
EXEC up_LinkCheckDate 2
or
EXEC up_LinkCheckDate 3
