setSqlSelect	SELECT 查询字段	举例
where	WHERE 语句，拼接 + WHERE 条件
and	AND 语句，拼接 + AND 字段=值
andNew	AND 语句，拼接 + AND (字段=值)
or	OR 语句，拼接 + OR 字段=值	.eq(" name “,” 木子 “). or ( ). eq (” id ", 1 ) => name=“木子” or id=1 注意事项：主动调用or表示下一个方法不是and连接，不调用默认为使用and连接
orNew	OR 语句，拼接 + OR (字段=值)
eq	等于=	.eq(“name”,“木子”) => name=“木子”
allEq	基于 map 内容等于=
ne	不等于<>
gt	大于>
ge	大于等于>=
lt	小于<
le	小于等于<=
like	模糊查询 LIKE	.like(“name”,“木子”) => name like ‘%木子%’
notLike	NOT LIKE模糊查询
in	IN 查询	.in(“age”,{1,2,3}) => age in (1,2,3)
notIn	NOT IN 查询
isNull	NULL 值查询
isNotNull	IS NOT NULL
groupBy	分组 GROUP BY
having	HAVING 关键词
orderBy	排序 ORDER BY
orderAsc	Asc 排序 ORDER BY
orderDesc	DESC 排序 ORDER BY
exists	EXISTS 条件语句
notExists	NOT EXISTS 条件语句
between	BETWEEN 条件语句	.between (“age”,1,2) => age between 1 and 2
notBetween	NOT BETWEEN 条件语句
addFilter	自由拼接 SQL
last	拼接在最后，例如：last(“LIMIT 1”)
