In SQLite3 I am going to be storing a very long string that looks something like this:
string linkList = "www.blah.com,www.meh.com,www.hah.com";
will definitely exceed 255 chars, will probably be over 1000 chars
Should the column linkList
be a varchar
, TEXT
or something else to store a string that will probably be longer than 1000 chars
CREATE TABLE(uId INT PRIMARY KEY, linkList varchar);
What would be the best variable type to use for the column linkList
?
SQLite text and BLOB values are always variable length. The maximum size of a text or BLOB value is limited by a compile-time directive. The default limit is exactly one billion bytes, or slightly less than a full gigabyte.
INTEGER. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value. Since long is 8 byte and INTEGER can also save values of 8 bytes, you can use INTEGER .
(9) What is the maximum size of a VARCHAR in SQLite? SQLite does not enforce the length of a VARCHAR. You can declare a VARCHAR(10) and SQLite will be happy to store a 500-million character string there. And it will keep all 500-million characters intact.
TEXT
.Although, that's the same thing as VARCHAR
:
If the declared type of the column contains any of the strings "CHAR", "CLOB", or "TEXT" then that column has TEXT affinity. Notice that the type VARCHAR contains the string "CHAR" and is thus assigned TEXT affinity
And also:
Note that numeric arguments in parentheses that following the type name (ex: "VARCHAR(255)") are ignored by SQLite - SQLite does not impose any length restrictions (other than the large global SQLITE_MAX_LENGTH limit) on the length of strings, BLOBs or numeric values.
"SQLite does not impose any length restrictions"
Actually, all data types in SQLite is no matter, all data will be stored as strings. You can execute query CREATE TABLE(uId INT PRIMARY KEY, linkList BlahBlahString);
without any error. Data type in SQLite is for sql compability only
