I have Adaptive Server Anywhere version 6.
I have discovered in ISQL that, with the very same SQL statement, the engine doe not always choose the same index to retrieve the records. There must me some smart mechanism that tries to find out what the optimal index will be.
Sometimes I do not agree with the index chosen, so i would like to know I there is a way to force a specific index.
