What are the data types supported by SQLite?

Question

Aryan Kumar · Answer

SQLite supports the following data types:

INTEGER: An integer is a whole number without a decimal point.
REAL: A real number is a number with a decimal point.
TEXT: A text is a string of characters.
BLOB: A BLOB is a binary large object, which can store any type of data, including images, audio, and video.

In addition to these basic data types, SQLite also supports a number of other data types, such as:

DATETIME: A DATETIME is a date and time value.
TIME: A TIME is a time value.
DATE: A DATE is a date value.
NUMERIC: A NUMERIC is a number with a fixed precision.
CHAR: A CHAR is a fixed-length string.
VARCHAR: A VARCHAR is a variable-length string.
REALM: A REALM is a secure data type that can be used to store sensitive data.

The data type of a column is specified when the column is created. For example, the following statement creates a column called id of type INTEGER:

Code snippet

CREATE TABLE employees (
  id INTEGER PRIMARY KEY
);

Once a column has been created, its data type cannot be changed.

The data type of a column determines the range of values that can be stored in the column. For example, an INTEGER column can store any whole number, while a TEXT column can store any string of characters.

The data type of a column also affects the performance of queries that are performed on the column. For example, queries on INTEGER columns are typically faster than queries on TEXT columns.

When choosing a data type for a column, it is important to consider the range of values that will be stored in the column and the performance requirements of the queries that will be performed on the column.
