Trennen und erneut anhängen von db2 partitionierten Tabellen

Question

Ich erstellte eine partitionierte Tabelle. Aber ich habe falsche Syntax verwendet 'MAXVALUE'. Dies muss MAXVALUE wie folgt sein. Wie kann dieses Problem behoben werden?

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 par6 STARTING 'A1001001A17G01A00000A00001' ENDING 'A1001001A17L31C35959J99999' IN OBJECTS05, 
    PARTITION par7 STARTING 'A1001001A18G01A00000A00001' ENDING 'A1001001A18L31C35959J99999' IN OBJECTS06, 
    PARTITION par8 STARTING 'A1001001A19G01A00000A00001' ENDING 'A1001001A19L31C35959J99999' IN OBJECTS07, 
    PARTITION par9 STARTING 'B0000000000000000000000001' ENDING 'MAXVALUE' IN OBJECTS08 
    ); 

Answer 1

traurig, dass wir die DB2 Multisystem PTF haben uns nicht auf unseren iSeries-System installiert, so kann ich die SQL-Anweisungen nicht testen, aber hier wäre meine Lösung neu befestigen Par9 sein:

ALTER TABLE RMOBJECTSPAR DETACH PARTITION par9 
INTO dummy; 

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

Dies sollte Ihr Problem lösen, aber bitte zuerst testen, um sicherzustellen, dass.

Auf einer Seite zur Kenntnis, vielleicht Ihre Partitionen wie diese stattdessen definieren:

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 
    );
