Dao.update介绍

[英]Update all rows in the table according to the prepared statement parameter. To use this, the UpdateBuilder must have set-columns applied to it using the UpdateBuilder#updateColumnValue(String,Object) or UpdateBuilder#updateColumnExpression(String,String) methods.
[中]根据prepared statement参数更新表中的所有行。要使用此方法，UpdateBuilder必须使用UpdateBuilder#updateColumnValue（String，Object）或UpdateBuilder#updateColumnExpression（String，String）方法对其应用set列。
