Value#Project#Lastupdate Here it doesn't matter what the delimiter is. But given that Value can have ANY value present in there,I can't just use a very complicated separator which MIGHT cover 99.999999 % of all cases but in 1 case out of 100 of millions it wont. So what I did was ...
除了使用Oracle内置的函数外,还可以创建自定义函数来拆分逗号分隔的字符串。 示例: CREATEORREPLACEFUNCTIONsplit_string(p_stringINVARCHAR2,p_delimiterINVARCHAR2)RETURNsys.OdciVarchar2ListPIPELINEDASl_start PLS_INTEGER:=1;l_end PLS_INTEGER;BEGINLOOPl_end:=INSTR(p_string,p_delimiter,l_start);IFl_...
Oracle SQL使用重复的分隔符拆分字符串 ,可以使用CONNECT BY LEVEL和SUBSTR函数的组合来实现。 具体操作步骤如下: 首先,创建一个可以用作分隔符的字符: 代码语言:txt 复制 SELECT ',' AS delimiter FROM dual; 使用CONNECT BY LEVEL生成与字符串中分隔符的数量相等的行数。假设要拆分的字符串为'1,2,3,4,5'...
例如,PostgreSQL提供了函数regexp_split_to_table,它可以根据正则表达式拆分字符串并返回一个表。示例代码如下: 其中,column_name是包含多个值的字段名,delimiter是用于分隔值的正则表达式。 使用递归查询:对于一些不支持内置函数或正则表达式的数据库管理系统,可以使用递归查询来实现数据拆分。递归查询是一种通过递归调用...

使用STRING_SPLIT函数拆分字符串(适用于SQL Server 2016及以上版本): SELECT value FROM STRING_SPLIT('apple,banana,orange', ','); 复制代码 使用REGEXP_SUBSTR函数拆分字符串(适用于Oracle): SELECT REGEXP_SUBSTR('apple,banana,orange', '[^,]+', 1, LEVEL) AS part FROM DUAL CONNECT BY REGEXP...
If you have Oracle APEX 5.1 or later installed, you can use the convenient APEX_STRING.split function, e.g.: select q.Name, q.Project, s.column_value as Error from mytable q, APEX_STRING.split(q.Error, ',') s The second parameter is the delimiter string. It also accepts a 3rd...
SELECT value FROM STRING_SPLIT('hello,world', ','); 输出: | value | |---| | hello | | world | 该函数是SQL Server 2016引入的,在MySQL和Oracle中暂无该函数。 4. 自定义函数 以下是一个MySQL中自定义的拆分函数示例: DELIMITER // CREATE FUNCTION split_str(str VARCHAR(255), delimiter...
