Implementations

impl<'a> Wrapper<'a>

pub fn new() -> Self

pub fn eq<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

等于

pub fn not_eq<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

不等于

pub fn is_null<T>(self, column: &dyn ColumnExt) -> Self

where T: ToSql + Sync,

空值

pub fn is_not_null<T>(self, column: &dyn ColumnExt) -> Self

where T: ToSql + Sync,

非空值

pub fn between<T>(self, column: &dyn ColumnExt, min: &'a T, max: &'a T) -> Self

where T: ToSql + Sync,

在范围

pub fn not_between<T>( self, column: &dyn ColumnExt, min: &'a T, max: &'a T ) -> Self

where T: ToSql + Sync,

不在范围

pub fn like<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

like 向前匹配还是向后匹配由前端进行控制

pub fn set_in<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

in

pub fn gt<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

大于

pub fn ge<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

大于等于

pub fn lt<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

小于

pub fn le<T>(self, column: &dyn ColumnExt, obj: &'a T) -> Self

where T: ToSql + Sync,

小于等于

设置排序

pub fn set_order_by_column_ext( self, order_by: &dyn ColumnExt, desc: bool ) -> Self

设置排序参数是ColumnExt 类型

pub fn get_order_by(self) -> Option<String>

pub fn get_page_info(self) -> (String, u64, u64, u64)

pub fn build( self, args_number: u32 ) -> Result<(String, Vec<&'a (dyn ToSql + Sync)>), String>

@description: @param {} self @param {u32} args_number 从1开始 @param {} Vec @return {*}
