INSERT INTO Database Explained

The insert statement in a database is used to insert new records into a table. The basic syntax is as follows:

INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);

In this case, table_name is the name of the table where the records should be inserted, (column1, column2, column3, …) are the column names to be inserted, and (value1, value2, value3, …) are the values to be inserted.

If you want to insert values for all columns, you can omit the column names, like this:

INSERT INTO table_name
VALUES (value1, value2, value3, ...);

Additionally, you can use the SELECT statement to insert data, as shown below:

INSERT INTO table_name (column1, column2, column3, ...)
SELECT value1, value2, value3, ...
FROM another_table_name;

This method allows for selecting data from another table and inserting it into the current table.

It is important to note that the values being inserted must match the column definition of the table, otherwise the insertion will fail.
