3.4 查看sp使用了哪些表
select bname from syscat.packagedep where btype="T" and pkgname in(select bname from sysibm.sysdependencies where dname in (select specificname from syscat.procedures where procname="PR_CLEAR_MATCH_DIVIDE_SHA"))
3.5 查看function被哪些sp使用
select PROCNAME from SYSCAT.PROCEDURES where SPECIFICNAME in(select dname from sysibm.sysdependencies where bname in ( select PKGNAME from syscat.packagedep where bname in (select SPECIFICNAME from SYSCAT.functions where funcname="GET_CURRENT_DATE")))
使用function时要注意，如果想drop 掉该function必须要先将调用该function的其它存储过程全部drop掉。 数据挖掘论坛
必须先创建function，调用该function的sp才可以创建成功。
3.6 修改表结构
一次给一个表增加多个字段
db2 "alter table tb_test add column t1 char(1) add column t2 char(2) add column t3 int"
4 DB2系统管理
4.1 DB2安装
在Windows 98 下安装db2 7.1 或其他版本，如果有Jdbc错误或者是Windwos 98不能启动，则将autoexec.bat 中的内容用如下内容替换：
C:PROGRA~1TRENDP~1PCSCAN.EXE C: C:WINDOWSCOMMAND /NS /WIN95
rem C:WINDOWSCOMMAND.COM /E:32768
REM [Header]
REM [CD-ROM Drive]
