本文整理了Java中net.sf.jsqlparser.statement.select.Limit类的一些代码示例，展示了Limit类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Limit类的具体详情如下：
包路径：net.sf.jsqlparser.statement.select.Limit
类名称：Limit

Limit介绍

[英]A limit clause in the form [LIMIT {[offset,] row_count) | (row_count | ALL) OFFSET offset}]
[中]格式为[limit{[offset，]row_count）|（row_count | ALL）offset}]的limit子句
