Ms sql updating one table from another

How to insert data from one table to another table by using SQL Server There are various ways to insert data from one table to another table. Using INSERT INTO This method is used when the table is already existing in the database.

Data will be inserted into this table from another table.

- El cuadro o cuadros para copiar de la tabla de origen - La tabla de origen o las tablas que forman parte de una subconsulta.

- El orden de las clases, si desea copiar las filas en un orden determinado.

- Group By opción, si desea copiar una síntesis de la información.

You don't have to list the columns If columns listed in insert clause and select clause are egual and with the same type.

But to avoid any mistake, I recommand you to list each column.
