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:

转换的 Count SQL:

转换的分页 SQL:
