FROM STRING_SPLIT('apple,banana,orange', ','); 使用自定义函数:如果需要更复杂的拆分逻辑,可以编写自定义函数来实现。以下是一个简单的示例函数,用于将字符串按照指定的分隔符拆分成多个值: 代码语言:txt 复制 CREATE FUNCTION dbo.SplitValues ( @inputString NVARCHAR(MAX), @delimiter NVARCHAR(10) ) RETUR...

STRING_SPLIT# 说明:将字符串分割为列 STRING_SPLIT(str_val) 实例: SELECTvalueFROMSTRING_SPLIT('1,2,3,4,5,6,7,8,9,10',','); 结果: 实例: SELECTvalueFROMSTRING_SPLIT('dog cat fish bird lizard',' '); 结果: STRING_AGG# 说明:将选中的多个列合并到一个行中 STRING_AGG(ColumnName, Conc...
As you can see, the RIGHT function has expectedly taken the last three characters of the string passed into it, and the LEFT function has taken the first three. Pretty simple! CHARINDEX CHARINDEX is another simple function that accepts two arguments. The first argument is the cha...
I am trying to create a stored procedure that will split 3 text boxes on a webpage that have user input that all have comma delimited strings in it. We have a field called 'combined_name' in our table that we have to search for first and last name and any known errors or nicknames...
标量函数(Scalar Function):接受一个或多个参数,并返回一个标量值。标量函数可以用于计算、转换和处理数据。例如,LEN函数用于返回字符串的长度。 表值函数(Table-Valued Function):接受一个或多个参数,并返回一个表作为结果。表值函数可以用于查询和处理数据。例如,SPLIT_STRING函数用于将字符串拆分为表格形式。 聚合...
怎么样:CREATE FUNCTION dbo.NTH_ELEMENT (@Input NVARCHAR(MAX), @Delim CHAR = '-', @N INT = 0)RETURNS NVARCHAR(MAX)ASBEGINRETURN (SELECT VALUE FROM STRING_SPLIT(@Input, @Delim) ORDER BY (SELECT NULL) OFFSET @N ROWS FETCH NEXT 1 ROW ONLY)END 0 0 0 没找到需要的内容?换个关键词再...
You've tagged this SQL Server 2008 but future visitors to this question (using SQL Server 2016+) will likely want to know about STRING_SPLIT. With this new builtin function you can now just use SELECT TRY_CAST(value AS INT) FROM STRING_SPLIT ('1,2,3,4,5,6,7,8,9,10,11,12,13...
12 STRING_SPLIT is a table-valued function. STRING_AGG Return a string that consists of concatenated string values in row groups. SELECT STRING_AGG(C, ',') FROM VALUES(1, 'a'), (1, 'b'), (2,'c') AS X (ID,C) GROUP BY I 1 'ab' ...
SQL Server 2016 introduced the STRING_SPLIT() function. It has two parameters - the string to be chopped up and the separator. The output is one row per value returned. For the given example SELECT * FROM string_split('one,two,three,four', ','); will return value --- one ...
