I thought full-text search would let me do exact phrase searching in a more optimized way than a LIKE predicate, but I'm reading that it doesn't do that exactly. Is "LIKE" the most efficient way to search thousands of rows of TEXT fields in a table for a literal string? It's got to be exact matching... ...

I find this quite odd on Microsoft SQL Server: SELECT * FROM deliveries WHERE code LIKE '01999195000%' -- 9 rows returned. Works. DECLARE @a VARCHAR(10) SET @a='01999195000%' SELECT * FROM deliveries WHERE code LIKE @a -- 0 rows returned? Why not? SET @a = '01999195000' SELECT * FROM deliveries WHERE code LIKE @a + '%' -- 9 rows retur...
