3/20/2023 0 Comments Sqlite boolean![]() SQLite does not have a separate Boolean storage class. This column may contain values using all five storage classes.īehaves the same as a column with NUMERIC affinity, with an exception in a CAST expression.īehaves like a column with NUMERIC affinity except that it forces integer values into floating point representation.Ī column with affinity NONE does not prefer one storage class over another and no attempt is made to coerce data from one storage class into another.įollowing table lists down various data type names which can be used while creating SQLite3 tables with the corresponding applied affinity. This column stores all data using storage classes NULL, TEXT or BLOB. Each table column in an SQLite3 database is assigned one of the following type affinities − Sr.No. ![]() Any column can still store any type of data but the preferred storage class for a column is called its affinity. SQLite supports the concept of type affinity on columns. The INTEGER storage class, for example, includes 6 different integer datatypes of different lengths. SQLite storage class is slightly more general than a datatype. The value is a blob of data, stored exactly as it was input. The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16LE) The value is a floating point value, stored as an 8-byte IEEE floating point number. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value. SQLite Storage ClassesĮach value stored in an SQLite database has one of the following storage classes − Sr.No. In SQLite, the datatype of a value is associated with the value itself, not with its container. SQLite uses a more general dynamic type system. You would use these data types while creating your tables. Each column, variable and expression has related data type in SQLite. SQLite data type is an attribute that specifies the type of data of any object.
