> SUBSTRING function in SQL Server behaves almost like what in Calcite.
> The only slight difference is the number of arguments. For example, the 
> following expression will throw "The substring function requires 3 
> argument(s)." in SQL Server, but succeed in Calcite, which means 
> substringLength argument is required for SQL Server.
> {code:java}
> SELECT substring('abcdef', 1)
> {code}
