db2“描述”控制台表输出不可读

Question

我不知道如何称呼这个“混乱的控制台输出”，所以我不能用谷歌寻求解决方案。

我运行db2 describe indexes for table TABLENAME show detail

我如何以人类可读的格式读取此命令的输出？

Answer 1

db2 describe indexes for table TABLENAME | vim

没有一种方法可以告诉DB2命令行处理器以不同的格式输出数据。

Answer 2

$ db2 -f myfile.sql

--#SET TERMINATOR @

SET SERVEROUTPUT ON@
