In summary, the PARSENAME function is a handy addition to your T-SQL toolkit for writing queries involving delimited data. It allows for parsing out and returning individual segments of a string value into separate columns. Since the PARSENAME function breaks down the string, you are not oblig...
INSERT INTO语句用于插入一些示例数据,DataString列包含了用逗号分隔的名字。 步骤2: 编写用于拆分字符串的函数 接下来,我们需要编写一个函数来拆分字符串并将结果以表格形式返回。这里我们可以创建一个名为SplitString的函数。 CREATEFUNCTIONdbo.SplitString(@InputStringVARCHAR(100),@DelimiterCHAR(1))RETURNS@OutputTa...
As seen in above SQL query, concatenated string data in database table columns can be splitted using the sample split string function and Cross Apply. The output of the query is as follows. In this T-SQL split sample code, SQL programmers can see how easy is to use the XML in split s...

result, you'll need to use a different function which does. Personally, I recommendDelimitedSplit...
split 特别注意split(string,delimiter) 在presto delimiter是 分隔符 但是hive中的这个函数,第二个参数是正则表达式。这也是为什么某些特殊字符需要用\转义字符的原因,加上hive里面转义字符有需要双反斜线\\ 容易困惑,提醒一下大家 split_apart select split_part('192.1.1.2','.',1) as result ...

QUOTENAME returns a Unicode string with the delimiters added to make the input string a valid identifier. The QUOTENAME function uses this syntax: 複製 QUOTENAME ( 'string' [ , 'delimiter' ] ) You pass QUOTENAME a string to be delimited and a one-character string...
