更新表列>甲骨文

這是我迄今爲止更新表列>甲骨文

BEGIN 
      UPDATE t1 
       set t1.LANGUAGE_ID = (case NETWORK.NID 
         when 11 then 10 
         else 7 
         end) 
       FROM PROFILE, NETWORK where 
       PROFILE.STATUS in ('A','U','S','H','I') 
       AND PROFILE.MID = t1.MID 
       AND NETWORK.MID = t1.MID 
       AND t1.IS_DELETED = 'N' 
END;

四處錯誤：

"ORA-06550: line 7, column 21: 
PL/SQL: ORA-00933: SQL command not properly ended 
ORA-06550: line 2, column 18: 
PL/SQL: SQL Statement ignored 
ORA-06550: line 12, column 4: 
PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following: 

    (begin case declare end exception exit for goto if loop mod 
    null pragma raise return select update while with 
    <an identifier> <a double-quoted"

我想更新T1 t1.is_deleted時=」 N'，而同樣位於配置文件中的狀態爲AUSHI。所有的表格都有一箇中間的列。任何想法，爲什麼我得到這個錯誤？

UPDATE聲明在Oracle中沒有FROM子句。

這聽起來像你想有一個相關的更新

UPDATE t1 
    SET t1.language_id = (SELECT (CASE WHEN network.nid = 11 
             THEN 10 
             ELSE 7 
            END) 
          FROM profile, 
           network 
          WHERE profile.status IN ('A','U','S','H','I') 
          AND profile.mid = t1.mid 
          AND network.mid = t1.mid 
          AND t1.is_deleted = 'N');

這會的t1設置language_id每一行更新到NULL如果相關子查詢不返回行。如果你只想在t1更新行，其中有子查詢

UPDATE t1 
    SET t1.language_id = (SELECT (CASE WHEN network.nid = 11 
             THEN 10 
             ELSE 7 
            END) 
          FROM profile, 
           network 
          WHERE profile.status IN ('A','U','S','H','I') 
          AND profile.mid = t1.mid 
          AND network.mid = t1.mid 
          AND t1.is_deleted = 'N') 
    WHERE EXISTS(SELECT 1 
        FROM profile, 
         network 
       WHERE profile.status IN ('A','U','S','H','I') 
        AND profile.mid = t1.mid 
        AND network.mid = t1.mid 
        AND t1.is_deleted = 'N');

非常感謝。雖然現在我得到的ORA-01427：單行子查詢返回多個行 – jgvb 2013-03-19 15:44:21

這只是因爲它是一個複合主鍵，謝謝 – jgvb 2013-03-19 15:58:19

由@Justin提供的解決方案的偉大工程返回匹配行，但如果你的表較大，則可以考慮使用MERGE代替。使用提供的查詢，您爲表t1的每一行運行嵌套SELECT查詢一次。
