I have a program connecting to DB but when I call the table it says the tables does not exist. I have deleted table and remade it a few times. I am using the sqlite manager plugin for firefox, there is a sqlite_master table.
When I select that table it does not give me any errors...
I think it has to do with it adding main when I create the table and add data to it.
is it adding main as a prefix?
INSERT INTO "main"."contacts" ("Business_Name","First_Name","Last_Name","Phone","Email","Address_Line_1","Address_Line_2","Website") VALUES (?1,?2,?3,?4,?5,?6,?7,?8)
Parameters:
param 1 (text): Texcom
param 2 (text): Jesse
param 3 (text): Lovelace
param 4 (text): 817-555-9999
param 5 (text): jlove@gmail.com
param 6 (text): 852 hemming way
param 7 (text): Colleyville, TX 76034
param 8 (text): www.texcom.com
Anyone have any ideas here?

请检查您的连接字符串,检查完整路径:
DriverManager.getConnection("jdbc:sqlite:YOUR_DATABASE_PATH");
