The jdbc driver does not support positioned updates or deletes Jdbc驅(qū)動程序不支持定位更新或定位刪除。
Positioned updates use the current of clause to specify a cursor 定位更新使用current of子句指定游標(biāo)。
If the row was modified , the attempted positioned update or delete fails 如果已修改該行,則嘗試進行的定位更新或刪除將失敗。
Specifies that positioned updates or deletes made through the cursor are guaranteed to succeed 指定通過游標(biāo)進行的定位更新或刪除保證會成功。
A positioned update using a where current of clause updates the single row at the current position of the cursor 使用where current of子句的定位更新將在游標(biāo)的當(dāng)前位置更新單行。
