1. 使用V$LOCK視圖

V$LOCK是Oracle系統(tǒng)視圖之一，用于顯示當(dāng)前會(huì)話持有的鎖信息，通過查詢V$LOCK視圖，可以獲取到鎖的ID、會(huì)話ID、鎖類型、鎖模式、對象ID等信息。

SELECT
    SID,
    SERIAL#,
    BLOCK,
    ID1,
    ID2,
    LMODE,
    TYPE,
    OBJID1,
    OBJID2,
    OBJNAME1,
    OBJNAME2
FROM
    V$LOCK;

2. 使用DBA_BLOCKERS和DBA_WAITERS視圖

DBA_BLOCKERS和DBA_WAITERS是兩個(gè)DBA級別的視圖，分別用于顯示阻塞會(huì)話和等待會(huì)話的信息，通過查詢這兩個(gè)視圖，可以獲取到會(huì)話ID、鎖模式、對象ID等信息。

查詢阻塞會(huì)話
SELECT
    B.SID AS BLOCKING_SESSION,
    B.SERIAL# AS BLOCKING_SERIAL#,
    B.MACHINE AS BLOCKING_MACHINE,
    B.PROGRAM AS BLOCKING_PROGRAM,
    B.USERNAME AS BLOCKING_USERNAME,
    B.OSUSER AS BLOCKING_OSUSER,
    B.OBJID AS BLOCKING_OBJECT_ID,
    B.OBJNAME AS BLOCKING_OBJECT_NAME,
    B.LMODE AS BLOCKING_LOCK_MODE
FROM
    DBA_BLOCKERS B;
查詢等待會(huì)話
SELECT
    W.SID AS WAITING_SESSION,
    W.SERIAL# AS WAITING_SERIAL#,
    W.MACHINE AS WAITING_MACHINE,
    W.PROGRAM AS WAITING_PROGRAM,
    W.USERNAME AS WAITING_USERNAME,
    W.OSUSER AS WAITING_OSUSER,
    W.OBJID AS WAITING_OBJECT_ID,
    W.OBJNAME AS WAITING_OBJECT_NAME,
    W.LMODE AS WAITING_LOCK_MODE
FROM
    DBA_WAITERS W;

3. 使用DBMS_UTILITY.FORMAT_LOCK_INFO函數(shù)

DBMS_UTILITY.FORMAT_LOCK_INFO是一個(gè)Oracle提供的實(shí)用函數(shù)，用于格式化鎖信息，通過調(diào)用這個(gè)函數(shù)，可以將鎖信息以字符串的形式返回，便于查看和分析。

SELECT
    DBMS_UTILITY.FORMAT_LOCK_INFO(B.SID) AS LOCK_INFO
FROM
    DBA_BLOCKERS B;

以上三種方法都可以用于查看Oracle數(shù)據(jù)庫中的表鎖信息，根據(jù)實(shí)際需求選擇合適的方法進(jìn)行查詢。
