Ignore_Ucase_Support
The Embedded Database supports case insensitive index segments. This is a feature that other databases do not support. Some databases support case insensitive columns (by using a case insensitive collating sequence for a column). When converting a table that uses case insensitive index segments, extra columns will be created that store the uppercased value of the original column. This extra column is used in index definitions as a segment to achieve the case insensitive index segment functionality. In order to be able to generate the correct find statements, the driver uses the back end’s uppercase scalar function in the WHERE clause of the SELECT statement generated to implement a find.
This attribute will switch the case insensitive index segment logic on or off. When ignored (true) it is switched off, when not ignored (false) it is switched on.
This default value is copied to database level when logging in to the database. The actual value in use for an active connection is that on database level. This attribute merely reflects a default.
