indizes: automatic use or activate by query?

Hi all,

i want to know if i have to activate each index seperate in query ( iE: with (index(abc))) or if the sql server is intelligent enough to chose the correct/needed index by himself?

Thanks and regards, Sabrina

This forum is for questions about SQL Anywhere (not SQL Server!)... but if the question is about SQL Anywhere then my response is: Why would you want to do that? SQL Anywhere is fairly intelligent and it is best to let it decide what indexes to use.

1	The key phrase in your question is "if i have to" rather than "how do I". For SAP SQL Anywhere the answer is no. For Microsoft SQL Server the answer is no. permanent link answered 20 Jul '15, 13:52 Breck Carter 32.5k●539●724●1050 accept rate: 20% edited 20 Jul '15, 13:53 flat view
