SQLite Reset Primary Key Field

Solution 1:

Try this:

delete from your_table;    
delete from sqlite_sequence where name='your_table';

SQLite Autoincrement

SQLite keeps track of the largest ROWID that a table has ever held using the special SQLITE_SEQUENCE table. The SQLITE_SEQUENCE table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.

Solution 2:

You can reset by update sequence after deleted rows in your-table

UPDATE SQLITE_SEQUENCE SET SEQ=0 WHERE NAME='table_name';

Solution 3:

As an alternate option, if you have the Sqlite Database Browser and are more inclined to a GUI solution, you can edit the sqlite_sequence table where field name is the name of your table. Double click the cell for the field seq and change the value to 0 in the dialogue box that pops up.
