I have seen SQL that uses both != and <> for not equal. What is the preferred syntax and why? I like !=, because <> reminds me of. Which of these queries is the faster? NOT EXISTS: SELECT ProductID, ProductName FROM Northwind..Products p WHERE NOT EXISTS. SQL Server 2008,SQLServer2008. El SQL Server configuration manager, generalmente es accesible como complemento de la consola de administracin. Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case. The query.
This question also has the answer, but it mentions DB2 specifically. How do I search for a string using LIKE that already.
