Error description

  • If the following Objects are created in the order below :
    
    CREATE TABLE "DB2INST1"."TAB1" ( "COLA" TIMESTAMP NOT NULL WITH
    DEFAULT CURRENT TIMESTAMP , "COLB" CHAR(10) NOT NULL WITH
    DEFAULT '' ) IN USERSPACE1 ORGANIZE BY ROW
    DB20000I The SQL command completed successfully.
    
    CREATE INDEX "DB2INST1"."TAB1_PRIM" ON "DB2INST1"."TAB1" ("COLA"
    ASC) COMPRESS NO INCLUDE NULL KEYS ALLOW REVERSE SCANS
    DB20000I The SQL command completed successfully.
    
    ALTER TABLE "DB2INST1"."TAB1" ADD CONSTRAINT "TAB1_CPRIM"
    PRIMARY KEY ("COLA")
    SQL0598W Existing index "DB2INST1.TAB1_PRIM" is used as the
    index for the primary key or a unique key. SQLSTATE=01550
    
    DB2LOOK with the -CT option will generate the following DDL :
    
    CREATE TABLE "DB2INST1"."TAB1" ( "COLA" TIMESTAMP NOT NULL WITH
    DEFAULT CURRENT TIMESTAMP , "COLB" CHAR(10) NOT NULL WITH
    DEFAULT '' ) IN USERSPACE1 ORGANIZE BY ROW;
    
    ALTER TABLE "DB2INST1"."TAB1" ADD CONSTRAINT "TAB1_CPRIM"
    PRIMARY KEY ("COLA");
    
    CREATE INDEX "DB2INST1"."TAB1_PRIM" ON "DB2INST1"."TAB1" ("COLA"
    ASC) COMPRESS NO INCLUDE NULL KEYS ALLOW REVERSE SCANS;
    
    
    Where the INDEX and the PRIMARY KEY are not in the same order.
    
    
    As a consequence, the Index is not created when the DDL is
    replayed :
    
    CREATE TABLE "DB2INST1"."TAB1" ( "COLA" TIMESTAMP NOT NULL WITH
    DEFAULT CURRENT TIMESTAMP , "COLB" CHAR(10) NOT NULL WITH
    DEFAULT '' ) IN USERSPACE1 ORGANIZE BY ROW
    DB20000I The SQL command completed successfully.
    
    ALTER TABLE "DB2INST1"."TAB1" ADD CONSTRAINT "TAB1_CPRIM"
    PRIMARY KEY ("COLA")
    DB20000I The SQL command completed successfully.
    
    CREATE INDEX "DB2INST1"."TAB1_PRIM" ON "DB2INST1"."TAB1" ("COLA"
    ASC) COMPRESS NO INCLUDE NULL KEYS ALLOW REVERSE SCANS;
    SQL0605W The index was not created because an index
    "DB2INST1.TAB1_CPRIM" with a matching definition already exists.
    SQLSTATE=01550
