| hi everybody,I have a table called CENTERS which has only two records and CENTER_ID is the primary key for the table,and also CENTER_ID is used in many other tables as a foreign key.Now my doubt is, is it required to create a non-clustered index on CENTER_ID column in all the other refering tables???? |

| By Default Primary key create a Clustered index if there is no any other clustered index in a table.Indexing depend on the query not on the constraint,check index requirement with the help of query you have developedRegards,Syed Jahanzaib Bin HassanMCTS,MCITP,OCA,OCP,OCE,SCJP,IBMCDBAMy Blogwww.aureus-salah.com |
