How SQL Server saves the contents of a query to a new SQL table

I'm using a statement to save the queried data to a new table

1) using the into table statement, the new table that needs to be saved does not need to be created in advance

Select *    to from table-Insert new Table statement into TableName        

2) using the Insert Table statement, the new table that needs to be saved does not need to be created in advance

CREATE TABLE [dbo].[newtable](    [Fdsequenceid][bigint]  not NULL,    [Fdinnertime][Date]  not NULL,    [Fdtime][Date]  not NULL,    [Fddata][float] NULL,    [fdstate][int]  not NULL,    [Fdupdatetime][datetime]  not NULL,    [fdrate] [float] NULL,    [Fdcreatetime][datetime]  not NULL)InsertNewTableSelect *  from Table
