BaseDatastoreAdapter
The list of key words tested against is defined to contain all SQL/92 keywords, plus any additional
key words reported by the JDBC driver for this adapter via DatabaseMetaData.getSQLKeywords().
In general, use of a SQL key word as an identifier should be avoided. SQL/92 key words are divided into reserved and non-reserved words. If a reserved word is used as an identifier it must be quoted with double quotes. Strictly speaking, the same is not true of non-reserved words. However, as C.J. Date writes in A Guide To The SQL Standard :
The rule by which it is determined within the standard that one key word needs to be reserved while another need not is not clear to this writer. In practice, it is probably wise to treat all key words as reserved.
