Multiple inserts against single insert from temp table

Hi,

I have table (AttributeID INT NOT NULL, ValueID INT NOT NULL), both of them are foreign keys. I need replace several rows which have same AttributeID and various ValueID with new values. So I must delete all rows WHERE AttributeID=@.AttributeID and then insert new values. What is better,

for every row make one call to SP which will do single INSERT;

or supplies all ValueIDs as single parameter to SP and then extracts ValueIDs them to temp table and then do INSERT MyTable SELECT * FROM #TempTable.

Which solution will be faster ? Or do you have idea for other solution which will outperform those two ?

Much thanks for your replies.

In general, a set base solution (i.e. single dml that affects more than one row at a time) is faster and better than row-per-row. So, if you have lots of rows to be processed, putting the data into a temp table (i.e. staging table) then invoking a single dml command would give you the most bang for your buck.

Multiple Contain Statements

I need some help with this syntax
Select * FROM PROJECTS
WHERE CONTAINS(Problem_Description, '"Invalid use of null"') And WHERE
CONTAINS(Problem_Status, '"Open"')
Can you have multiple CONTAINS Statements?
I am getting a syntax error with the above code snippet. What am I missing?
Thanks!You have an extra WHERE clause. CONTAINS is a predicate, and you can
logically combine predicates using AND or OR; you only need one WHERE
clause:
WHERE CONTAINS(x, 'abc') AND CONTAINS(y, 'def')
But in your case, I'm wondering if you really want to use full-text search
for your problem status column? Will the status really be more than one
word? You'd probably have much better luck using:
WHERE CONTAINS(Problem_Description, '"Invalid use of null"')
AND Problem_Status = 'Open'
