Data Types

Let's go through each data type in SQLite along with code examples for creating tables using these data types.

INTEGER (Whole Numbers)

The INTEGER data type is used for storing whole numbers. Here's an example of creating a table with this data type:

In this example, a table "integers" is created with columns "id" and "value," both having the INTEGER data type.

REAL (Floating-Point Numbers)

The REAL data type is used for storing floating-point numbers, including decimal and scientific notation. Here's an example of creating a table with this data type:

In this example, a table "real_numbers" is created with columns "id" and "price," where "price" has the REAL data type.

TEXT (Text Strings)

The TEXT data type is used for storing text strings. Here's an example of creating a table with this data type:

In this example, a table "text_data" is created with columns "id" and "name," where "name" has the TEXT data type.

BLOB (Binary Objects)

The BLOB data type is used for storing binary data, such as images, audio, or other binary files. Here's an example of creating a table with this data type:

In this example, a table "binary_data" is created with columns "id" and "content," where "content" has the BLOB data type.

These examples demonstrate how to define data types when creating a table in SQLite using Python. Each data type defines how data will be stored and processed within the table.
