If your string always contain A as character then you can try this Select replace ( 'A1' , 'A' , '' ) Select replace ( 'A10' , 'A' , '' ) Select replace ( 'A100' , 'A' , '' ) After getting the values you can cast it as integer as shown below. Select Cast ( replace ( 'A1000' , 'A' , '' ) as Integer ) You can also try the following query. SELECT LEFT ( SUBSTRING ( 'A100' , PATINDEX( '%[0-9.-]%' , 'A100' ), 8000), PATINDEX( '%[^0-9.-]%' , SUBSTRING ( 'A100' , PATINDEX( '%[0-9.-]%' , 'A100' ), 8000) + 'X' ) -1) SELECT Cast ( LEFT ( SUBSTRING ( 'A100' , PATINDEX( '%[0-9.-]%' , 'A100' ), 8000), PATINDEX( '%[^0-9.-]%' , SUBSTRING ( 'A100' , PATINDEX( '%[0-9.-]%' , 'A100' ), 8000) + 'X' ) -1) as Integer ) as OnlyNumbers If you want to get the maximum value with added one then you can write the following query. SELECT Cast ( LEFT ( SUBSTRING ( 'A100' , PATINDEX( '%[0-9.-]%' , 'A100' ), 8000), PATINDEX( '%[^0-9.-]%' , SUBSTRING ( 'A100' , PATINDEX( '%[0-9.-]%' , 'A100' ), 8000) + 'X' ) -1) + 1 as Integer ) as OnlyNumbers You can pass the column name also in place of the hardcode values. create table YourTable ( Col varchar (100) ); insert into YourTable values ( 'AB ABCDE # 123' ), ( 'ABCDE# 123' ), ( 'AB: ABC# 123' ), ( 'A1005' ) Select stuff(Col, 1, patindex( '%[0-9]%' , Col)-1, '' ) from YourTable Hope this will help you.
