一、什么是PL/SQL?
PL/SQL(Procedural Language/SQL)是对SQL的扩充,它吸收了近年来编程语言的许多最高设计特点:如数据封装性、信息隐蔽性、重载和例外处理等。它允许SQL的数据操纵语言和查询语句包含在块结构(block_structured)和代码过程语言中,使PL/SQL成为一个功能强大的事务处理语言。

1.查询表空间的使用情况，以M为单位
select f.tablespace_name,a.total,u.used,f.free,round((u.used/a.total)*100) "% used",
round((f.free/a.total)*100) "% Free"

INSTR方法的格式为
INSTR(源字符串, 目标字符串, 起始位置, 匹配序号)
例如：INSTR('CORPORATE FLOOR','OR', 3, 2)中，源字符串为'CORPORATE FLOOR', 目标字符串为'OR'，起始位置为3，取第2个匹配项的位置。
默认查找顺序为从左到右。当起始位置为负数的时候，从右边开始查找。
所以SELECT INSTR('CORPORATE FLOOR' ......
