With NOWAIT, the statement reports an error, rather than waiting, if a selected row cannot be locked immediately.

Returns:

the current object

of

FOR UPDATE / FOR SHARE OF tables

Parameters:

paths - tables

Returns:

the current object

clone

public PostgreSQLQuery<T> clone(Connection conn)

Specified by:

clone in class AbstractSQLQuery<T,PostgreSQLQuery<T>>

select

public <U> PostgreSQLQuery<U> select(Expression<U> expr)

select

public PostgreSQLQuery<Tuple> select(Expression<?>... exprs)
