sql

public BaseQuery sql(String sql)

追加sql，注意顺序，查询中存在 orderByAsc 或者 orderByAsc 时，
orderByAsc 或者 orderByAsc 将会生成到sql最后面
例如 new Query().orderByAsc("id").sql(" name=#{name}") 报错
将会输出错误sql：select * from my_table order by id asc name=#{name}

参数:

sql - 要追加的sql，例如 limit 1，输出sql：select id from t_user where 1=1 limit 1

返回:

追加sql

sql

public BaseQuery sql(String sql,
 Map<String,Object> param)

追加sql，注意顺序，查询中存在 orderByAsc 或者 orderByAsc 时，
orderByAsc 或者 orderByAsc 将会生成到sql最后面
例如 new Query().orderByAsc("id").sql(" name=#{name}") 报错
将会输出错误sql：select * from my_table order by id asc name=#{name}

参数:

sql - id = #{id} and type= #{type}

param - new MapParam().add("id","1").add("type","user")

返回:
