Question

我尝试在Clob数据类型中插入超过32k字节的数据，但出现错误：-

语句执行失败：[IBM] [CLI驱动程序] [DB2 / LINUXX8664] SQL0102N以“嗨，早安团队：我们被要求向所有人添加安妮尔”开头的字符串常量太长。 SQLSTATE = 54002 SQLCODE = -102

请找到我的DDL语句：-

CREATE TABLE "DB2IDEV "."CHANGE"  (
      "TICKET_ID" INTEGER NOT NULL ,
      "SHORTDESC" VARCHAR(5000 OCTETS) NOT NULL ,
      "LONGDESC" CLOB(2147483647 OCTETS) LOGGED NOT COMPACT ,
      "RELEASENUM" VARCHAR(12 OCTETS) WITH DEFAULT NULL ,
      "ISSOFTDELETED" INTEGER NOT NULL WITH DEFAULT 0 ,
      "CREATETIMESTAMP" TIMESTAMP NOT NULL WITH DEFAULT CURRENT TIMESTAMP ,
      "LASTUPDATETIMESTAMP" TIMESTAMP WITH DEFAULT NULL )  
     IN "TABLESPACE" 
     ORGANIZE BY ROW  ;

INSERT INTO DB2IDEV.Change ( 
    Ticket_ID,shortDesc,longDesc,releaseNum,isSoftDeleted, 
    createTimeStamp,lastUpdateTimeStamp) 
    VALUES (
        '296129',
        'High Cisco Adaptive Security Appliance Remote Code Execution and Denial of Service Vulnerabilit',
        '<Some long data around 50KB in size>',
        NULL, '0','2018-02-07 02:11:50',NULL
    )

SQL0102N：

说明

发生以下情况之一：

...       以string开头的字符串常量的长度大于32672个字节。长度大于32672的字符串   长度大于16336个字符的字节或图形字符串   只能通过从主机变量赋值来指定。注意   DB2产品家族中的其他服务器可能会指定一个   字符串的大小限制不同。查阅文档   有关适当的数据库产品的详细信息。

对于如此长的常数，必须使用相应的变量。像这样：

ibm_db_conn = ibm_db.connect(...)
sql = """INSERT INTO DB2IDEV.Change ( 
    Ticket_ID,shortDesc,longDesc,releaseNum,isSoftDeleted, 
    createTimeStamp,lastUpdateTimeStamp) 
    VALUES (
        '296129',
        'High Cisco Adaptive Security Appliance Remote Code Execution and Denial of Service Vulnerabilit',
        ?,
        NULL, '0','2018-02-07 02:11:50',NULL
    )"""
stmt = ibm_db.prepare(ibm_db_conn, sql)
clob='<Some long data around 50KB in size>'
ibm_db.bind_param(stmt, 1, clob)
ibm_db.execute(stmt)

如何在DB2的列中插入32KB以上的数据？
