该插件目前支持以下数据库的物理分页:

1. Oracle
2. Mysql
3. MariaDB
4. SQLite
5. Hsqldb
6. PostgreSQL
7. DB2
8. SqlServer(2005,2008)
9. Informix
10. H2
11. SqlServer2012
12. Derby
13. Phoenix

14. 达梦数据库

15. 阿里云PPAS

5.1.10

在 5.1.0 - 2017-08-28 版本中，增加 ReplaceSql 接口用于处理 sqlServer 的 with(nolock) 问题，增加了针对性的 replaceSql 参数， 可选值为 simple 和 regex，或者是实现了ReplaceSql接口的全限定类名。默认值为 simple，仍然使用原来的方式处理， 新的 regex 会将如 table with(nolock) 处理为 table_PAGEWITHNOLOCK。

本次更新仅仅是把默认值从 simple 改为了 regex，使用 regex 方式几乎能 100% 解决 sqlServer 的分页问题。

Starter 升级到了 1.2.12

下面是两个 issue 中的示例。

示例 SQL #76

原始 SQL：

SELECT *
FROM
forum_post_info a with(nolock)
LEFT JOIN forum_carcase_tags as b with(nolock) on a.id = b.carcase_id where b.tag_id = 127

转换的 Count SQL：

SELECT COUNT(0)
FROM forum_post_info a WITH (NOLOCK)
	LEFT JOIN forum_carcase_tags b WITH (NOLOCK) ON a.id = b.carcase_id
WHERE b.tag_id = 127

转换的分页 SQL：

SELECT TOP 10 *
FROM (
	SELECT ROW_NUMBER() OVER (ORDER BY RAND()) AS PAGE_ROW_NUMBER, *
	FROM (
		SELECT *
		FROM forum_post_info a WITH (NOLOCK)
			LEFT JOIN forum_carcase_tags b WITH (NOLOCK) ON a.id = b.carcase_id
		WHERE b.tag_id = 127
	) PAGE_TABLE_ALIAS
) PAGE_TABLE_ALIAS
WHERE PAGE_ROW_NUMBER > 1
ORDER BY PAGE_ROW_NUMBER

示例 SQL #398

原始 SQL：

Select AUS.ScheduleID, AUS.SystemID, AUS.ClinicID, AUS.DoctorID, AUS.ScheduleDate,
	AUS.StartTime, AUS.EndTime, AUS.Status, AUS.BookBy, AUS.Note, AUS.Remark, AUS.SourceType, CM.CompanyName,
	AU.UserName As DoctorName, AU.UserNumber As DoctorNumber, CC.CodeDesc As ClinicName, CD.Lat, CD.Lng,
	CD.ContactTel, CD.Address, CR.ConsultationStatusID, CR.RegisterStatus,A1.CodeDesc as AreaLevel1, A2.CodeDesc as AreaLevel2
	From ACM_User_Schedule AUS with(nolock)
	Left Join Client_Register CR with(nolock) On AUS.BookBy=CR.ClientID And CR.SourceType='F' And AUS.ClientRegisterNum=CR.ClientRegisterNum
	Inner Join ACM_User AU with(nolock) On AU.UserID = AUS.DoctorID
	Inner Join Code_Clinic CC with(nolock) On AUS.ClinicID=CC.CodeID
	Inner Join Clinic_Detail CD with(nolock) On CC.CodeID = CD.ClinicID
	Inner Join Code_Area A1 with(nolock) On CD.AreaLevel1ID=A1.CodeID
	Inner Join Code_Area A2 with(nolock) On CD.AreaLevel2ID=A2.CodeID
	Inner Join Company_Master CM with(nolock) On CC.SystemID = CM.SystemID
	Where BookBy=1

转换的 Count SQL：

SELECT COUNT(0)
FROM ACM_User_Schedule AUS WITH (NOLOCK)
	LEFT JOIN Client_Register CR WITH (NOLOCK)
	ON AUS.BookBy = CR.ClientID
		AND CR.SourceType = 'F'

	INNER JOIN Code_Area A2 WITH (NOLOCK) ON CD.AreaLevel2ID = A2.CodeID
	INNER JOIN Company_Master CM WITH (NOLOCK) ON CC.SystemID = CM.SystemID
WHERE BookBy = 1

转换的分页 SQL：

SELECT TOP 10 ScheduleID, SystemID, ClinicID, DoctorID, ScheduleDate
	, StartTime, EndTime, Status, BookBy, Note
	, Remark, SourceType, CompanyName, DoctorName, DoctorNumber
	, ClinicName, Lat, Lng, ContactTel, Address
