Class TableDef

java.lang.Object

org.melati.poem.prepro.TableDef

public class TableDef
extends Object

A Table Definition holding information from a DSD. The SQL table naming convention is enforced here: the name given in the DSD is forced to lowercase. This could be changed to enable mixed case names in jdbc names by simply not forcing to lowercase, but the JavaName has first letter capitalised. The way around this is to have a separate jdbc name, but this would be a lot of redundancy for a small use case. The use case is actually broken: MySQL allows significant table name case, but only on operating systems where file name case is significant, and the manual advises against. The solution is to add the following to /etc/mysqld/my.cnf [mysqld] lower_case_table_names=1
