What do you mean by data type in SQLite?
SQLite data type is an attribute that specifies the type of data of any object. Each column, variable and expression has related data type in SQLite. You would use these data types while creating your tables.
How are large files stored in a SQLite database?
FLOAT. There is only one way to store large files into a SQLite database, and it is using the BLOB data type. This data type is used to store large files like images, files (from any type), etc. The file is converted into bytes array and then stored in the same size as the input file. SQLite doesn’t have a separate BOOLEAN storage class.
What’s the default size of a string in SQLite?
2 Answers 2. There is a managable string or blob limit in SQLite. The default is 10^9 bytes. See documentation BTW you don’t need to specify it on column declaration anyway. SQLite does let you write VARCHAR(255) or NVARCHAR(255), but the only relevant part of that is CHAR (which gives the column “text affinity”).
How are data types assigned affinity in SQLite?
Any column declared in an SQLite database is assigned a type affinity depending on it declared data type. Here the lift of type affinities in SQLite: TEXT. NUMERIC. INTEGER. REAL. BLOB. Here’s how SQLite determines the affinity of the column from its declared data type: INTEGER affinity is assigned if the declared type contains the string ” INT “.

Is there a Max character length of a SQLite field?
The maximum number of bytes in a string or BLOB in SQLite is defined by the preprocessor macro SQLITE_MAX_LENGTH. The default value of this macro is 1 billion (1 thousand million or 1,000,000,000). You can raise or lower this value at compile-time using a command-line option like this:
Which is the default column size in SQLite?
The default is 10^9 bytes. See documentation BTW you don’t need to specify it on column declaration anyway. SQLite does let you write VARCHAR (255) or NVARCHAR (255), but the only relevant part of that is CHAR (which gives the column “text affinity”). The number in parentheses is allowed for compatibility with standard SQL, but is ignored.
What is the type affinity of a column in SQLite?
Type affinity of a column is the recommended type for data stored in that column. Note that the data type is recommended, not required, therefore, a column can store any type of data. In this tutorial, you have learned about SQLite data types and some important concepts including storage classes, manifest typing, and type affinity.
