the syntax below. I looked around and saw AUTOINCREMENT on this page http://www.sqlite.org/syntaxdiagrams.html#column-constraint but that did not work either. Without AUTO_INCREMENT my table can be created. An error occurred: near "AUTO_INCREMENT": syntax error CREATE TABLE fileInfo ( fileId int NOT NULL AUTO_INCREMENT, name varchar(255), status int NOT NULL, PRIMARY KEY (fileId) ); python sqlite share|improve this question asked Feb 3 '09 at 19:49 acidzombie24 42.6k136454813 add a comment| 3 Answers 3 active oldest votes up vote 33 down vote accepted This is addressed in the SQLite FAQ. Question #1. Which states: How do I create an AUTOINCREMENT field? Short answer: A column declared INTEGER PRIMARY KEY will autoincrement. Here is the long answer: If you declare a column of a table to be INTEGER PRIMARY KEY, then whenever you insert a NULL into that column of the table, the NULL is automatically converted into an integer which is one greater than the largest value of that column over all other rows in the table, or 1 if the table is empty. (If the largest possible integer key, 9223372036854775807, then an unused key value is chosen at random.) For example, suppose you have a table like this: CREATE TABLE t1( a INTEGER PRIMARY KEY, b INTEGER ); With this table, the statement INSERT INTO t1 VALUES(NULL,123); is logically equivalent to saying: INSERT INTO t1 VALUES((SELECT max(a) FROM t1)+1,123); There is a function named sqlite3_last_insert_rowid() which will return the integer key for the most recent insert operation. Note that the integer key is one greater than the largest key that was in the table just prior to the insert. The new key will be unique over all keys currently in the table, but it might overlap with keys that have been previously deleted from the table. To create keys that are unique over the lifet
