Whats the best SQLite data type for a long string

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?

Answer Source

You should use 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.
