How can I do the same in mysql.

I have tried like this

select reject_remarks,regexp_substr(reject_remarks,"[0-9]+")  from table; 

but have anything like I want

I have tried like this

select reject_remarks,regexp_substr(reject_remarks,"[0-9]+")  from table ;

>Solution :

you can use REGEXP_REPLACE where ou negate all possible allowed characters

CREATE Table mytable(reject_remarks varchar(100))

INSERT INTO mytable VALUES ('Will0017,Will0018, Kind0045 , DGRG0012')

SELECT  REGEXP_REPLACE(reject_remarks, '[^0-9,[:space:]]+', '') AS numbers 
FROM mytable;
