What is the method for creating a table and assigning values in SQLite?
To create a table and insert values in SQLite, you can follow these steps:
- Connect to the SQLite database by using either the SQLite command-line tool or the SQLite API.
- Create a table. Use the CREATE TABLE statement to create a table and specify the names of the fields and their data types. For example, create a table named “employees” with fields “id” (integer type), “name” (text type), and “age” (integer type).
- The table “employees” is created with columns for id (integer), name (text), and age (integer).
- Insert data. Use the INSERT INTO statement to insert data into a table. You can insert one row at a time or multiple rows at once. For example, insert a row of data into the “employees” table.
- Add the record of an employee named John Doe, aged 30, with an ID of 1, into the employees database table.
- Alternatively, insert multiple rows of data at once.
- Insert the following employees into the database:
– Employee ID: 2, Name: Jane Smith, Age: 25
– Employee ID: 3, Name: Bob Johnson, Age: 35. - Query the data. You can use a SELECT statement to retrieve data from the table to ensure that the data has been successfully inserted.
- Retrieve all information about employees.
- This will return all rows and columns in the “employees” table.
This is the basic method for creating a table and assigning values in SQLite. You can also use other SQL statements and SQLite features to manipulate the table as needed.
