I have know idea where to start I can select all the rows which have a , in Field A but I don't know where to start when trying to remove it.

Answer 1

If you'd rather not care about the length, STUFF is the right candidate :

UPDATE YourTable
SET    YourCol = STUFF(YourCol, 1, 1, '')
WHERE YourCol LIKE ',%'

Answer 2

UPDATE YourTable
SET    YourCol = SUBSTRING(YourCol, 2, 0+0x7fffffff) 
WHERE YourCol LIKE ',%'

Answer 3

You could use the RIGHT , LEN and RTRIM functions

UPDATE TableA
SET FieldA = RIGHT(RTRIM(FieldA), LEN(FieldA) - 1)
WHERE FieldA LIKE ',%'

Example

Answer 4

You can use TSQL SUBSTRING function

Use LEN to get the length of the field.

SUBSTRING(FieldA, 2, LEN(FieldA) - 1)
