Question

I am performing SQL prefix search in my ASP.NET application.For this purpose I have written a stored procedure in which i am writing following query:

SELECT Description, ProductDescriptionID
FROM Production.ProductDescription
WHERE CONTAINS (Description, ' "top*" ' );

I have parameter as @pvchProductName in my procedure.How can i replace top word with parameter value in above query?I am facing syntax problems with single and double quotations.

Answer 1

DECLARE @searchTerm nvarchar(60) = N' "' + @pvchProductName + N'*" ';
// where the "60" above should be adjusted to account for the length
// of pvchProductName, plus 5. So if pvchProductName is [n]varchar(30),
// then nvarchar(35) would be fine.

SELECT Description, ProductDescriptionID
FROM Production.ProductDescription
WHERE CONTAINS (Description, @searchTerm);

?

It is unclear, however, how much of the quotes / asterisks / whitespace you want to include in the filter condition – you may want to check that a bit.
