I am trying to insert data in to a table with an auto increment primary key.
My table structure is like this:
int:PK
varchar:Item_ID
varchar:Item_name
int:FK_type
When I try the prepared statement:
prep = conn.prepareStatement("insert into Inventory values (?, ?, ?);");
I get this Error:
Exception in thread "main" java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (table Inventory has 4 columns but 3 values were supplied)

When I try executing the statement:
stat.executeUpdate("insert into Inventory (Item_ID, Item_name, FK_type ) values ('TP1', 'NX Tripod 1', 2)");
I get this error:

What am I doing wrong?
Edit:
I get a [SQLITE_MISUSE] error when I try to add four columns in the statement.
Here is the method that inputs the data
protected static void insertItem() throws Exception {
stat.execute("insert into Inventory (Item_ID, Item_name, FK_type ) values ('TP1', 'NX Tripod 1', 2)");
}

Your table has four columns and your inserts are only inserting three values. Try removing a column from the table, or alternatively inserting four values when inserting a row.
