You should use cursors on T-SQL. Please see this link:

Keep foodtypes  ID as PRIMARY key. Refer this ID in the table pretoria as a REFERENCE key.

Search can be done using JOIN.

SELECT [col]
from foodtypes  ft
INNER JOIN pretoria  P
ON ft.ID = P.foodtypeid
where [your search condition].

Hi,

I recommend you never use cursors, they are slow and inefficient. There are almost always other ways to retrieve the information you need.

Do you want to search for more than one value in the foodtypes column, or just one?
