Question

我试图创建以下触发器（DB2 / LINUXX8664 9.7.2在Ubuntu 10.04.2 LTS上运行），但我总是这样：

Error report:
DB2 SQL error: SQLCODE: -1424, SQLSTATE: 54040, SQLERRMC: 2

根据IBM DB2文档：

Too many references to transition variables and transition table columns or the row length for these references is too long. Reason code=rc.

http://www-01.ibm.com/support/knowledgecenter/SSEPGG_9.5.0/com.ibm.db2.luw.messages.sql.doc/doc/msql01424n.html

我真的不明白这个解释。这里存储过程和触发器：

CREATE PROCEDURE SP_INSERT_UPDATE_REPNUM (
   IN RECNUM           INTEGER,
   IN CUSTOMER_ID      INTEGER,
   IN Q_CODE           VARCHAR(14),
   IN S_CODE           VARCHAR(14),
     IN REP_STATUS       INTEGER,
     IN P_CODE           INTEGER,
     IN REPNUMRG_ID      INTEGER,
     IN VOLG_LET         VARCHAR(1),
     IN REP_DATUM        DATE,
     IN REP_INI          VARCHAR(2),

     IN OMSCR_MAT        VARCHAR(5),
     IN REP_TIJD         FLOAT,
     IN REP_GEDAAN       CHAR(1),
     IN ACTION           CHAR(1)

这里是触发器：

CREATE TRIGGER INSERT_REPNUM
  AFTER INSERT ON REPNUM
  REFERENCING NEW ROW AS NROW
    FOR EACH ROW MODE DB2SQL
BEGIN 
  CALL SP_INSERT_UPDATE_REPNUM(
    NROW.RECNUM,
    NROW.CUSTOMER_ID,
    NROW.Q_CODE,
    NROW.S_CODE,
    NROW.REP_STATUS,
    NROW.P_CODE,
    NROW.REPNUMRG_ID,
    NROW.VOLG_LET,
    NROW.REP_DATUM,

    NROW.OMSCR_MAT,
    NROW.REP_TIJD,
    NROW.REP_GEDAAN,

  );
END

尝试执行触发器后，我收到错误消息。我该如何解决这个问题？

更新

看起来我需要创建一个临时表空间。列出我的所有表空间，我得到了一些超过4k的表空间，例如这个：

 Tablespace ID                        = 7
 Name                                 = TEMPSPACE1234
 Type                                 = Database managed space
 Contents                             = All permanent data. Regular table space.
 State                                = 0x0000
   Detailed explanation:
     Normal
 Total pages                          = 1024
 Useable pages                        = 1008
 Used pages                           = 432
 Free pages                           = 576
 High water mark (pages)              = 528
 Page size (bytes)                    = 32768
 Extent size (pages)                  = 16
 Prefetch size (pages)                = 16
 Number of containers                 = 1

Answer 1

1）创建32K缓冲池

示例：

CREATE BUFFERPOOL "BUFFERPOOLLARGE" IMMEDIATE
ALL DBPARTITIONNUMS  SIZE AUTOMATIC
NUMBLOCKPAGES 0
PAGESIZE 32 K;

2）创建一个32K SYSTEM TEMPORARY TABLESPACE

示例：

CREATE SYSTEM TEMPORARY TABLESPACE "TEMPSPACELARGE"
IN DATABASE PARTITION GROUP "IBMTEMPGROUP"
PAGESIZE 32 K
MANAGED BY AUTOMATIC STORAGE
EXTENTSIZE 32
BUFFERPOOL "BUFFERPOOLLARGE"
OVERHEAD INHERIT
TRANSFERRATE INHERIT
USING STOGROUP "IBMSTOGROUP"
FILE SYSTEM CACHING;

3）再次运行CREATE PROCEDURE Script。

OBS：在示例中，我使用了DB2 automatic TABLESPACE。

尝试创建触发器时，IBM DB2 SQLCODE -1424，SQLSTATE 54040
