Litebase, starting from version 2.0, has reserved words. So, you can not use these words as identifiers.

In the table below you have the reserved words from SQL2003 standard and from Litebase. Many words from SQL2003 standard are not in Litebase reserved words list, but we strongly recommend that you do not use these words, because in a near future they may become a Litebase reserved word.
