What is the T-SQL equivalent for ANSI-SQL substr?

[Don ISOE]

The field "AccountNum" is 21 characters long. The department number is
imbedded in the "AccountNum" field beginning in position 8 for 4 characters.
In an Access SQL view I am trying to use the SQL substring function but
Access query does not recognize it. substr([tablename.AccountNum],8,4) as
DeptNum
Does Access query have an equivalent expression to create the same results
as a substr function?

Mid()

The arguments are identical to Substring().

.... and BTW, the default SQL flavour in Access is JET SQL, not T-SQL. T-SQL
is the name of Microsoft SQL Server SQL.
