@TableName
VARCHAR
(
200
),
--
表名
@FieldList
VARCHAR
(
2000
),
--
显示列名，如果是全部字段则为*
@PrimaryKey
VARCHAR
(
100
),
--
单一主键或唯一值键
@Where
VARCHAR
(
2000
),
--
查询条件 不含'where'字符，如id>10 and len(userid)>9
@Order
VARCHAR
(
1000
),
--
排序 不含'order by'字符，如id asc,userid desc，必须指定asc或desc
--
注意当@SortType=3时生效，记住一定要在最后加上主键，否则会让你比较郁闷
@SortType
INT
,
--
排序规则 1:正序asc 2:倒序desc 3:多列排序方法
@RecorderCount
INT
,
--
记录总数 0:会返回总记录
@PageSize
INT
,
--
每页输出的记录数
@PageIndex
INT
,
--
当前页数
@TotalCount
INT
OUTPUT,
--
记返回总记录
@TotalPageCount
INT
OUTPUT
--
返回总页数
