請教TABLE LOCK MODE的問題 2007/06/08 14:39

各位前輩，你們好，小弟有個有關TABLE LOCK MODE的問題想請教，目前使用IDS 10.x版本，程式開發工具使用4GL。
日前新建立了一個table，於是呢當然要利用alter table modify lock mode (row)來修正該table的lock模式，也去systables和studio je工具裡面去查核，確定lock mode為row lock，但是當程式寫完之後，user上線使用的狀況一點都不像row lock，感覺就是page lock，明明不同筆資料，改A筆，B筆也不能改，程式的寫法都一直是這樣也沒� ��過，實在想不出來，故來跟各位前輩求救，感恩...
程式寫法列於下方
DECLARE t100_cl CURSOR FOR
SELECT * FROM xia_file
WHERE ROWID = g_xia_rowid FOR UPDATE

OPEN t100_cl
FETCH t100_cl INTO g_xia.*

How many records will be updated in your "select..for update" TRANSACTION? This is nothing to do with table lock mode. All the locking records will only be released once you have committed. 文章曾經由此用戶編輯: Eric Lam, 於: 2007/06/13 03:35

不好意思可能是我描述不清楚我一次是根據g_xia_rowid來lock一筆資料 A user如果正在修改ROWID=2350這筆 B usre叫出ROWID-2365這筆資料要進行修改的動作系統就會出現-244的錯誤訊息別的程式都不會這樣唯讀這支程式搭配xia_file table就會這樣我程式寫法都沒變過
