Hi,

Is it possible to remove the first two characters from a table column and place those characters in another separate field.
The fields are both VARCHAR.
Any help would be appreciated.
Thanks

Select myField, substring(myField,3,len(myField)-2) as FromCharacter3, substring(myField,1,2) as FirstTwoCharacters
from MyTable

Sure:
UPDATE TableName
SET ColTwo = LEFT(ColOne,2),
   ColOne = RIGHT(ColOne,LEN(ColOne)-2),

ColOne is the field to remove the first two characters.
ColTwo is the field where those two characters will be placed.

If the data has leading or trailing spaces, you may want to trim and you can avoid the rows that have no data in the field.

update mytable
set mycol2 = left(ltrim(rtrim(mycol1)), 2),
   mycol1 = right(ltrim(rtrim(mycol1)), len(ltrim(rtrim(mycol1))) - 2)
where ltrim(rtrim(isnull(mycol1, ''))) <> ''

FYI, the separate column with only two characters would be more efficient as:
char(2)
rather than varchar(2).

be aware that len will result in you losing trailing spaces from the column if that could be important to you.

you might want to use datalength instead which deals with numbers of bytes (which need to be divided by 2 if it is an NVARCHAR column)
