Returns the SQL to get the database key of the last row inserted. SapDB doesn't have this, so it returns null.
Overrides:

Returns:
null.

getSequenceSql

public java.lang.String getSequenceSql(java.lang.Object sequenceName)
Returns the next key from a sequence. Databases like SapDB which support this feature will return a result, others will return null. SapDB does this by returning select sequenceName.nextval from dual
Overrides:
getSequenceSql in class DB
Parameters:
sequenceName, - An object of type String
Returns:
The next database key.
