To import a dataset into a relational table in SQLite, do the following:
Create a CSV file for your dataset in which the first row is a row containing the attribute names.
If you don’t already have the necessary CSV file, one way to createit is to open/import your dataset in Excel, add a row with theattribute names at the top of the file if there isn’t already onethere, and then use File->Save As to save the data as a CSV file.
Start up DB Browser for SQLite, which you installed as part of Problem Set 2.
Click the New Database button to create a database file for your data. Choose an appropriate name for the database file (e.g., project) and put it in the folder that you’re using for your work on the project.
After creating the database file, an Edit table definition dialog box may open. Click the Cancel button to close it.
Choose the File -> Import -> Table from CSV file menu option, which will open a dialog box. Use it to find your CSV file and choose Open.
If necessary, modify the default name listed for the table. This is the name that you will use in the FROM clause of your SQL commands.
Click the checkbox next to the words Column names in first line, which will cause SQLite Manager to use the names in the first line of the CSV file as the names of the attributes in the table.
Click the OK button at the bottom of the tab to create the table.
By default, all of the columns will be given the type Text, which is SQLite’s version of CHAR/VARCHAR.
If you want to change the type of any of the columns, click on the name of the table in the list of tables, and then click the Modify Table button. In the resulting dialog box, use the drop-down menus in the Type column to change the types of the columns as needed. You can also click the checkbox in the PK column for the attribute that is your primary key.
Once you have chosen data types for all of the columns, click the OK button.
You should now be ready to work with your data in SQLite Manager by entering SQL commands in the Execute SQL tab. You can also browse through the contents of the table using the Browse Data tab.
