见表报如下错误：
DB21034E The command was processed as an SQL statement because it was not a
valid Command Line Processor command. During SQL processing it returned:
SQL1024N A database connection does not exist. SQLSTATE=08003
见表语句如下：

------解决方案--------------------------------------------------------
示例：
创建用的脚本testTRI.sql：
create trigger testTRIGGER after update on test
referencing old as OR new as NR
for each row
mode DB2SQL
when (OR.id<>NR.id)
BEGIN ATOMIC
update test set CODE = '3' WHERE ID = NR.ID;
END@
创建用的命令：db2 -td@ -f /workspace/test/testTRI.sql
将你上述代码存为SQL文件，再用db2 -td@ -f /workspace/test/testTRI.sql导入
------解决方案--------------------------------------------------------
你先连接数据库
db2 connect to 数据库名 user 用户名 using 密码
------解决方案--------------------------------------------------------
你是在命令行下输入代码 ？连接数据库没有？
------解决方案--------------------------------------------------------
SQL1024N A database connection does not exist --这个错误，就是你没有先链接数据库
可以先链接一次，然后执行你的sql文件，或者把链接数据库的语句放到sql文件中一起执行。
