The first method is on how to use Standard SQL to split a string by a delimiter. For that, we can use the split() function as shown in the syntax below: SPLIT(value[, delimiter]) The function takes the string and the delimiter as the arguments. Then, it splits the string based on...
1、@String :需要split的字符串 2、@Delimiter:格式化时分隔符 3、@index:返回split后数组的值 ALTERFUNCTION[dbo].[GetCount_Split_StrByDelimiter](@StringVARCHAR(8000),@DelimiterCHAR(1),@indexchar(1))RETURNSvarchar(100)ASBEGINDECLARE@temptableTABLE(itemsVARCHAR(8000))DECLARE@SplitCountvarchar(100)DECLAR...

定义完成后,通过命令:SELECT SPLIT_STR(string, delimiter, position)使用,但该函数只是实现了split,但并为分离所有的,一定程度上仍然不满足。 定义函数中可能会遇到【ERROR 1418 (HY000): This function has none of DETERMINISTIC, NO SQL, xxx】错误,通过set global log_bin_trust_function_creators=1;设置即可...
Real World Example for SQL Split Column by Delimiter Here in the real world, DBA’s are often faced with more complex tables or views and not just a simple two column table as in the above sample. Although the sample above is a great primer for dissecting how to parse a string value,...
引入了一个新的内置表值函数STRING_SPLIT,它将指定的分隔字符拆分提供的输入字符串,并以 table 的形式返回输出分隔值,每个分隔符之间的每个分隔值都有一行。 STRING_SPLIT 函数有两个参数: STRING_SPLIT(字符串,分隔符) 该字符串是具有 char,nchar,varchar 或 nvarchar 数据类型的字符表达式。分隔符是单个字符,用于...
FROMSTRING_SPLIT(@List, @Delimiter) )ASs ); The outer query can thenORDER BY ListPosor, if you're trying to find the nthelement,WHERE ListPos = n. You could also addpointerto the output to determine how far into the string a given entity appears. ...
STRING_SPLIT inputs a string that has delimited substrings and inputs one character to use as the delimiter or separator. Optionally, the function supports a third argument with a value of 0 or 1 that disables or enables, respectively, the ordinal output column.STRING_SPLIT outputs a single-...
