i want to make a stored procedure for custom search on these two tables with the following fields given to the user as an option to make his choice..
from opportunity table -
OpportunityTypeID,SLABased,AccountID ,
GeographyID,
VerticalID,
BDMID,
Probability

and from skill table
SkillID, Location, GeoLocation

and return all the fields of opportunity table.

Can some make the stored procedure for me..
