REGEXP_LIKE 函数的一般语法是: 其中match_parameter 可以包括以下几种: 'c':表示大小写敏感(Case sensitive)。 'i':表示大小写不敏感(Case insensitive)。 'n':允许模式匹配符号 "." 匹配换行符。 'm':将源字符串视为多行,其中 ^ 和 $ 分别匹配每行的开始和结束,而不是整个字符串的开始和结束。 如果...
select h.froomnumber from t_broker_house h where REGEXP_LIKE(froomnumber,'^([a-z0-9A-Z]|-)*$') 字符串’^198[0-9]$’可以匹配‘1980-1989’,如果希望统计出公司那些员工是80年～89年入职的,就可以使用如下的SQL语句: select * fromempe whereregexp_like(to_char( e.hiredate,'yyyy'),'^...

Use uppercase and lowercase to improve the readability of your code (PL/SQL is case-insensitive). As a guideline, use uppercase for reserved words and lowercase for everything else. Avoid deeply nested IF-THEN-ELSE condition control. Use IF-THEN-ELSIF instead. ...
This element is case-insensitive. The default is TM9, which returns the number in fixed notation unless the output exceeds 64 characters. If output exceeds 64 characters, Oracle automatically returns the number in scientific notation. Restrictions: You cannot precede this element with any other...
User names should be created in upper case if possible, to remove the need to quote them if used in client-side PL/SQL. If it is not possible or feasible to configure the data source to be case insensitive, or to create objects with upper case names, you can still use Forms Developer...
We've already seen the most common workaround – converting all the characters to a standard case. You can also do case-insensitive comparisons usingregexp_like. But what if you want this to happen transparently, like with column-level collation? Or need accent-insensitive searches?
SKIPJOINS are like PRINTJOINS, but they do not become part of the word. Declaring SKIPJOINS of "*" lets SQL*Plus be lexed as "SQLPlus". STARTJOINS are like PRINTJOINS, but they only come at the start of the word. If they occur in the middle of a word, a new word is started...
