Method Detail

getAlias

EntityAlias<?> getAlias()

Returns:

the EntityAlias to work on (select from, insert into, etc.). For regular Statements this will be EntityAlias<E> but for special queries such as tuple or constructor queries this is not bound to the generic <E>.

getParameters

List<Object> getParameters()

Returns:

an unmodifiable List with the bind variables.

getSql

String getSql()

Specified by:

getSql in interface Command

Returns:

the current SQL String of this Statement. May only be an SQL fragment as the final operation such as FeatureFetch.fetch() will complete the statement. Has to be rebuild after every modification to the Statement.

getDialect

SqlDialect getDialect()

Returns:

the SqlDialect to use.

toString

String toString()

Overrides:

toString in class Object

Returns:

the same as getSql().
