Method Detail

getCurrentTimestampCommand

protected String getCurrentTimestampCommand()

Description copied from class: AnsiSQLBeanSession

Get the command representing 'now' in this database. This base implementation returns null, in other words, no now command will be used.

Overrides:

getCurrentTimestampCommand in class AnsiSQLBeanSession

Returns:

the command for now in this database (now(), sysdate, etc)

handleLimit

protected StringBuilder handleLimit(StringBuilder sb,
                        OrderBy orderBy,
                        Limit limit)

PostgreSQL will sort first then apply limit

Overrides:

handleLimit in class AnsiSQLBeanSession

Returns:

A string builder with the the SQL modified for the limit operation

insert

public void insert(Object bean)

Description copied from interface: BeanSession

Insert the bean in the database. Depending on the type of PK, the generation of the PK can and should be taken care by the DB itself. The generated PK should be inserted in the bean by reflection, before the method returns. The default, database-independent implementation of this method, insert all fields in the database not worrying about PK generation strategies.

Specified by:

insert in interface BeanSession

Overrides:

insert in class AnsiSQLBeanSession

Parameters:

bean - The bean to insert

isVarcharUnlimitedSupported

protected boolean isVarcharUnlimitedSupported()

Description copied from class: AnsiSQLBeanSession

Each dialect can override this to return true if the VARCHAR type supports unlimited size

Overrides:

isVarcharUnlimitedSupported in class AnsiSQLBeanSession

Returns:

true if database supports VARCHAR with no limit, false otherwise

getDatabaseType

protected String getDatabaseType(DBType<?> dbType)

Description copied from class: AnsiSQLBeanSession

Each dialect can override this to return the database column type it supports other than the ANSI standard.

Overrides:

getDatabaseType in class AnsiSQLBeanSession

Returns:

The string representation of this database type to be used with create table statement
