返回MPJLambdaQueryWrapper的com.github.yulichang.query中的方法

限定符和类型	方法和说明
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.disableLogicDel() 关闭主表逻辑删除
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.distinct() sql去重 select distinct
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.enableLogicDel() 启用主表逻辑删除
protected MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.instance() 用于生成嵌套 sql 故 sqlSelect selectColumn ignoreColumns from不向下传递
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.join(String keyWord, boolean condition, String joinSql)
MPJLambdaQueryWrapper<T>	MPJQueryWrapper.lambda() 返回一个支持 lambda 函数写法的 wrapper
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.select(boolean condition, List<com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>> columns)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.select(Class<T> entityClass, java.util.function.Predicate<com.baomidou.mybatisplus.core.metadata.TableFieldInfo> predicate) 只针对主表 过滤查询的字段信息(主键除外!)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.select(com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>... columns) SELECT 部分 SQL 设置
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.select(String... columns)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.selectAll(Class<?> clazz, String as) 查询表全部字段
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.selectAll(Class<T> clazz) 查询主表全部字段
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.selectIgnore(com.baomidou.mybatisplus.core.toolkit.support.SFunction<T,?>... columns) 忽略查询字段 用法: selectIgnore("t.id","t.sex","a.area")
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.selectIgnore(String... columns) 忽略查询字段 用法: selectIgnore("t.id","t.sex","a.area")
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.setAlias(String alias)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.setEntityClass(Class<T> entityClass)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.setIfAbsent(java.util.function.BiPredicate<Object,IfAbsentSqlKeyWordEnum> ifAbsent)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.setIfAbsent(java.util.function.Predicate<Object> ifAbsent)
MPJLambdaQueryWrapper<T>	MPJLambdaQueryWrapper.setTableName(java.util.function.Function<String,String> func) 动态表名 如果主表需要动态表名,主表实体必须添加 @DynamicTableName 注解 关联表则不需要 加不加注解都会生效
