22.4.4.1 向表中插入记录
You can use the insert()
method with the values()
method to insert records into an existing relational table. The insert()
method accepts individual columns or all columns in the table. Use one or more values()
methods to specify the values to be inserted.
To insert a complete record, pass to the insert()
method all columns in the table. Then pass to the values()
method one value for each column. For example, to add a new record to the city table in the world_x
database, insert the following record and press Enter twice.
mysql-py> db.city.insert("ID", "Name", "CountryCode", "District", "Info").values(
None, "Olympia", "USA", "Washington", '{"Population": 5000}')
The city table has five columns: ID, Name, CountryCode, District, and Info. Each value must match the data type of the column it represents.
The following example inserts values into the ID, Name, and CountryCode columns of the city table.
mysql-py> db.city.insert("ID", "Name", "CountryCode").values(
None, "Little Falls", "USA").values(None, "Happy Valley", "USA")
When you specify columns using the insert()
method, the number of values must match the number of columns. In the previous example, you must supply three values to match the three columns specified.
