com.github.yulichang.wrapper中BaseFuncEnum的使用

参数类型为BaseFuncEnum的com.github.yulichang.wrapper中的方法

限定符和类型	方法和说明
MPJLambdaWrapper<T>	MPJLambdaWrapper.selectFunc(boolean condition, BaseFuncEnum funcEnum, Object column, String alias)
MPJLambdaWrapper<T>	MPJLambdaWrapper.selectFunc(boolean condition, BaseFuncEnum funcEnum, Object column, String alias)
<S> MPJLambdaWrapper<T>	MPJLambdaWrapper.selectFunc(boolean condition, BaseFuncEnum funcEnum, com.baomidou.mybatisplus.core.toolkit.support.SFunction<S,?> column, String alias)
<S> MPJLambdaWrapper<T>	MPJLambdaWrapper.selectFunc(boolean condition, BaseFuncEnum funcEnum, com.baomidou.mybatisplus.core.toolkit.support.SFunction<S,?> column, String alias)

com.github.yulichang.wrapper.enums中BaseFuncEnum的使用

实现BaseFuncEnum的com.github.yulichang.wrapper.enums中的类

限定符和类型	类和说明
class	DefaultFuncEnum 常用的sql函数枚举 默认实现 可以自己实现接口 BaseFuncEnum 自定义函数 目前支持一个占位符,不支持多个%s 只例举几个通用的,其他函数 first() last() len() ucase() lcase() 等 或者数据库自定义函数请自行扩展 mpj的初衷是只针对简单的连表查询,而非相对复杂的查询, 建议慎用,复杂的查询还是推荐写sql
