Case sensitivity

Case sensitivity in databases refers to:

Case sensitivity of data

You decide the case-sensitivity of Sybase IQ data in comparisons when you create the database. By default, Sybase IQ databases are case-sensitive in comparisons, although data is always held in the case in which you enter it.

Adaptive Server Enterprise's sensitivity to case depends on the sort order installed on the Adaptive Server Enterprise system. Case sensitivity can be changed for single-byte character sets by reconfiguring the Adaptive Server Enterprise sort order.

Case sensitivity of identifiers

Sybase IQ does not support case-sensitive identifiers. In Adaptive Server Enterprise, the case sensitivity of identifiers follows the case sensitivity of the data.

In Adaptive Server Enterprise, user-defined data type names are case sensitive. In Sybase IQ, they are case insensitive.

User IDs and passwords

In Sybase IQ, passwords follow the case sensitivity of the data by default; however, you can also specify password case sensitivity independently of data case sensitivity. The default password for case-sensitive databases is uppercase SQL. The default user ID is DBA, but it is not case sensitive.

In Adaptive Server Enterprise, the case sensitivity of user IDs and passwords follows the case sensitivity of the server.
