Question

我有员工表，其中包含以下结构和数据。

id       name       empDetails                                                 phone
1        John       phone:7845982563,pinCode:7895645,subCode:22    
2        pitt       phone:7889451524,pinCode:2565479,subCode:24
3        ken        empId:3243,phone:283241524,pinCode:2563479,subCode:25  
4        rancho     empId:3263,phone:454424154,pinCode:5565479,subCode:24  
.         .                 .   

Sometimes phone poistion will be after empId also.

现在我想检查列empDetails

如果是，请使用字符串电话，然后获取电话号码并将其插入同一行的新电话栏中。

我们可以通过这种方式检查记录是否包含字符串电话。

SELECT employee.empDetails FROM employee WHERE  employee.empDetails LIKE '%phone:%'

但我们如何才能将电话号码转换为另一列并将其插入同一记录？

谢谢，雅利安

Answer 1

update  employee.empDetails set phone = cast(replace(empDetails, 'phone:', '') as unsigned) 
where employee.empDetails LIKE '%phone:%'

假设电话号码将始终以'phone：'为前缀
不是一个干净的答案。但是会做到这一点：）

Answer 2

SELECT replace(SUBSTRING_INDEX(empDetails,',',1),'phone:','') as phone 
FROM Table1 
where empDetails REGEXP '[[:<:]]phone[[:>:]]';

请遵循spaceman817的建议，使用单独的列。

希望这会有所帮助。

假设您的手机可以处于任何位置的开始，中间和结束。例如：

(1, 'John', 'phone:7845982563,pinCode:7895645,subCode:22'),
(2, 'pitt', 'pinCode:2565479,subCode:24,phone:7889451524'),
    (3, 'vk', 'pinCode:2565479,phone:7889451524,subCode:24');

使用以下查询：

SELECT  
replace(SUBSTRING_INDEX(SUBSTRING(empDetails,LOCATE('phone:',empDetails)),',',1),'phone:','') as phone
FROM Table1 where empDetails REGEXP '[[:<:]]phone[[:>:]]';

--- --- OUTPUT

Answer 3

尝试

update  employee set 
phone = SUBSTR(SUBSTRING_INDEX(empDetails,'phone:',-1) from 1 for  instr(SUBSTRING_INDEX(empDetails,'phone:',-1),',')-1)
where employee.empDetails LIKE '%phone:%'
