If you are looking for a proper SQL query to insert all rows from one table into another table, the INSERT INTO SELECT statement can come in handy.

The values for each row need to be separated by parenthesis for the correct execution. In the query above, we are adding 3 rows with 3 columns each to a single table. Therefore, it would not be possible to add values to different tables even within one database using this syntax. However, INSERT can only operate within a single table. The syntax of SQL Server allows inserting data into multiple rows of a table. VALUES (ColumnValue3) Using INSERT statement to insert multiple rows The query will look somewhat like this: INSERT INTO Employees (Column3) In case you are going to add only one record into a table, you will need to specify only the values you are willing to change.
