注释:在这段代码中,我们使用CHARINDEX查找字符'['和']'在Data字段中的位置,并将它们存储在StartIndex和EndIndex列中。 步骤3:使用SUBSTRING函数提取内容 现在,我们已经得到了符号的位置,接下来可以使用SUBSTRING函数提取这两个符号之间的内容。SUBSTRING函数通常用于从特定位置提取字符串。 以下是提取两者之间内容的代码:...
37--2、字符串中存在分隔符号,跳出while循环后,@location为0,那默认为字符串后边有一个分隔符号。3839RETURNSUBSTRING(@originalStr,@start,@location-@start);40END 调用函数:select dbo.Fun_GetStrArrayStrOfIndex('978-7-5007-7234-7','-',4) 结果:7234 三、像数组一样遍历字符串中的元素 代码语言:javas...

前面几种方式都是在 string 上做文章,要么 substring,要么 LastIndexOf,要么 EndsWith,其实也可以跳出这个定势思维,转换成数组进行处理,用union all作为分隔符切割字符串,如果数组的最后一个元素为 string.Empty,那就表明 sql 尾巴就是 keyword, 对吧,代码修改如下: ...

SQLGetSubString() is used to retrieve a portion of a large object value referenced by a large object locator. The large object locator has been returned from the data source (returned by a fetch or a previous SQLGetSubString() call) during the current tr
