Question

My trigger code not working when I added it to my program, it's giving error and will not connect to database.

The following code I suspected to be causing the problem because, other insertion queries were working fine before I added the trigger query.

public class Connect_db {

    Connection con;
    public static Statement st = null;

    public static Connection connectdb(){
       try{

           Class.forName("org.sqlite.JDBC");
           Connection con= DriverManager.getConnection("jdbc:sqlite:eGiftCard.db","","");
           st=con.createStatement();
           st.executeUpdate("CREATE TABLE IF NOT EXISTS SetUpReward(Number INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, \n"
                   + "min_Value DOUBLE (18, 2), \n"
                   + "max_Value DOUBLE (18, 2), \n"
                   + "reward_Point FLOAT, \n"
                   + "card_Length INTEGER, \n"
                   + "PayPal_Email TEXT, \n"
                   + "Bank_Name TEXT, \n"
                   + "Bank_Account TEXT)");

}

I am getting the following error.

java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database ()

Answer 1

CREATE TRIGGER IF NOT EXISTS eGiftCard.audit_log ...
INSERT INTO eGiftCard.ActivateAudit ...

数据库名称不是eGiftCard，而是main。数据库名称不与文件名相同。

这里没有理由使用数据库名称;只需删除eGiftCard.。

此外，缺少触发器END;。
