從db2分區表中分離並重新連接

-2

我創建了一個分區表。但我使用了不正確的引用語法'MAXVALUE'。這需要如下所示爲MAXVALUE。如何解決這個問題？從db2分區表中分離並重新連接

CREATE TABLE RMOBJECTSPAR (
        "OBJ_LIBRARYID" SMALLINT NOT NULL , 
        "OBJ_ITEMID" CHAR(26 OCTETS) NOT NULL , 
        "OBJ_VERSION" SMALLINT NOT NULL WITH DEFAULT 1 , 
        "OBJ_COLLECTIONID" INTEGER NOT NULL , 
        "OBJ_MGTCLASSID" SMALLINT NOT NULL , 
        "OBJ_STGCLASSID" SMALLINT NOT NULL , 
        "OBJ_ATTRIBUTES" SMALLINT NOT NULL WITH DEFAULT 0 , 
        "OBJ_RETENTION" INTEGER NOT NULL WITH DEFAULT 0 , 
        "OBJ_VOLUMEID" INTEGER NOT NULL , 
        "OBJ_STAGEDVOLUMEID" INTEGER NOT NULL WITH DEFAULT -1 , 
        "OBJ_PATH" INTEGER NOT NULL , 
        "OBJ_STATUS" CHAR(1 OCTETS) NOT NULL , 
        "OBJ_SIZE" BIGINT NOT NULL , 
        "OBJ_CREATEDATE" TIMESTAMP NOT NULL WITH DEFAULT CURRENT TIMESTAMP , 
        "OBJ_UPDATEDATE" TIMESTAMP NOT NULL WITH DEFAULT CURRENT TIMESTAMP , 
        "OBJ_REFERENCEDDATE" TIMESTAMP NOT NULL WITH DEFAULT CURRENT TIMESTAMP , 
        "OBJ_ACTIONDATE" DATE NOT NULL , 
        "OBJ_MGTCLASSDATE" DATE NOT NULL , 
        "OBJ_STGCLASSDATE" DATE NOT NULL , 
        "OBJ_PLAYSTATUS" CHAR(1 OCTETS) NOT NULL , 
        "OBJ_VOLSTATUS" CHAR(1 OCTETS) NOT NULL , 
        "OBJ_OBJECTNAME" VARCHAR(128 OCTETS) WITH DEFAULT '' , 
        "OBJ_ORGFILENAME" VARCHAR(1024 OCTETS) WITH DEFAULT '' , 
        "OBJ_FILENAME" VARCHAR(128 OCTETS) WITH DEFAULT '' , 
        "OBJ_MIMETYPE" VARCHAR(128 OCTETS) NOT NULL WITH DEFAULT 'text/html' , 
        "OBJ_OFFSET" BIGINT NOT NULL WITH DEFAULT -1 , 
        "OBJ_SIGNATURE" VARCHAR(514 OCTETS) FOR BIT DATA) 
PARTITION BY RANGE(OBJ_ITEMID) 
    (
    PARTITION par1 STARTING MINVALUE ENDING 'A1001001A14L31C35959J99999' IN OBJECTS, 
    PARTITION par2 STARTING 'A1001001A14A01A00000A00001' ENDING 'A1001001A14L31C35959J99999' IN OBJECTS01, 
    PARTITION par3 STARTING 'A1001001A15A01A00000A00001' ENDING 'A1001001A15F31C35959J99999' IN OBJECTS02, 
    PARTITION par4 STARTING 'A1001001A16G01A00000A00001' ENDING 'A1001001A16L31C35959J99999' IN OBJECTS03, 
    PARTITION par5 STARTING 'A1001001A16G01A00000A00001' ENDING 'A1001001A16L31C35959J99999' IN OBJECTS04,

    PARTITION par9 STARTING 'B0000000000000000000000001' ENDING 'MAXVALUE' IN OBJECTS08 
    );

抱歉，我們沒有安裝我們的iSeries系統上的DB2多系統PTF，所以我無法測試SQL語句，但這裏是我的解決方案重新連接par9：

ALTER TABLE RMOBJECTSPAR DETACH PARTITION par9 
INTO dummy; 

ALTER TABLE RMOBJECTSPAR ATTACH PARTITION par9 
STARTING FROM 'B0000000000000000000000001' ENDING AT MAXVALUE IN OBJECTS08 
FROM dummy;

這應該解決您的問題，但請首先測試以確保。

在一個側面說明，或許定義分區，這樣，而不是：

PARTITION BY RANGE(OBJ_ITEMID) 
    (
    PARTITION par1 STARTING MINVALUE ENDING 'A1001001A14A01A00000A00001' EXCLUSIVE IN OBJECTS, 
    PARTITION par2 STARTING 'A1001001A14A01A00000A00001' IN OBJECTS01, 
    PARTITION par3 STARTING 'A1001001A15A01A00000A00001' IN OBJECTS02, 
    PARTITION par4 STARTING 'A1001001A16G01A00000A00001' IN OBJECTS03, 
    PARTITION par5 STARTING 'A1001001A16G01A00000A00001' IN OBJECTS04, 
    PARTITION par6 STARTING 'A1001001A17G01A00000A00001' IN OBJECTS05, 
    PARTITION par7 STARTING 'A1001001A18G01A00000A00001' IN OBJECTS06, 
    PARTITION par8 STARTING 'A1001001A19G01A00000A00001' IN OBJECTS07, 
    PARTITION par9 STARTING 'B0000000000000000000000001' ENDING MAXVALUE IN OBJECTS08 
    );

引用我用：
