In java/src/nl/cwi/monetdb/jdbc/MonetDatabaseMetaData.java the methods getNumericFunctions(), getStringFunctions(), getSystemFunctions(), getTimeDateFunctions() and getSQLKeywords() are NOT correctly implemented. They all return "" which not correct.

In ODBC driver code (clients/odbc/driver/SQLGetInfo.c) these are implemented see: SQLGetInfo() for:
case SQL_NUMERIC_FUNCTIONS:
case SQL_STRING_FUNCTIONS:
case SQL_SYSTEM_FUNCTIONS:
case SQL_TIMEDATE_FUNCTIONS:
case SQL_KEYWORDS:

Step 1: MonetDatabaseMetaData.java needs to be updated for the mentioned methods.

Step 2: Ideally the list of supported functions should be retrieved from the server metadata (such as SYS.FUNCTIONS table). That way we do not need to manually sync the three (and possibly more) hard coded places, but it will become dynamic and in-sync with the SQL database server. This implementation however will require more programming and testing work.
