Description

« Hide

The current TCK test (carried over from JDO 1.0) for NotEquals, uses != operator on floating point numbers. This is not a good practice, and is unreliable. Its probably the case that the Equals test uses == on the same content, which also is not a good idea (as noted in the latest spec). These tests need reviewing and a reliable alternate strategy adopting

ASF	#358029	Tue Dec 20 16:21:23 UTC 2005	mbo	~~JDO-206~~: change the derby schema by using the column type REAL for all float fields. This also fixes a bug in the table PrimitiveTypes: the type of columns doubleNull and doubleNotNull should be DOUBLE instead of FLOAT.
