oracle存储过程中if语句
1.完整的存储过程如下：
这个存储过程内容可能有点多，这是我平时的项目用到的存储过程，刚好里面用到了if语句，所以我就拿来了给大家看一下

2.需要注意的地方
在写的时候，如果有多种情况，一定不要使用else if,因为这种用法在oracle存储过程中是错误的，应该使用elsif，第一次使用的时候我就用错了，所以怎么调都会报错，最后才发现是这里出了问题。所以正确的用法是下面这样的：
if p_info101 = '0' then
m_info101_word := '推进中';
elsif p_info101 = '1' then
m_info101_word := '已销号';
elsif p_info101 = '2' then
m_info101_word := '已取消';
end if;
还有一点，存储过程中的判断是否相等使用=，给变量赋值的时候使用:= 。
