如何在Java中執行SQL插入

-1

我試圖將數據插入到具有自動遞增主鍵的表中。我的表結構是這樣的：如何在Java中執行SQL插入

int:PK 
varchar:Item_ID 
varchar:Item_name 
int:FK_type

當我嘗試了事先準備好的聲明：

prep = conn.prepareStatement("insert into Inventory values (?, ?, ?);");

我得到這個錯誤：

Exception in thread "main" java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (table Inventory has 4 columns but 3 values were supplied) 
    at org.sqlite.DB.newSQLException(DB.java:383) 
    at org.sqlite.DB.newSQLException(DB.java:387)

    at org.checkout.CheckInventory.<init>(CheckInventory.java:58) 
    at org.checkout.main.main(main.java:18)

當我嘗試執行語句：

stat.executeUpdate("insert into Inventory (Item_ID, Item_name, FK_type) values ('TP1', 'NX Tripod 1', 2)");

我得到這個錯誤：

我在做什麼錯了？

編輯：

我得到一個[SQLITE_MISUSE]錯誤，當我嘗試在聲明中添加四列。

這裏是輸入數據

protected static void insertItem() throws Exception { 

    stat.execute("insert into Inventory (Item_ID, Item_name, FK_type) values ('TP1', 'NX Tripod 1', 2)"); 


}

似乎是相同的表現：https://bitbucket.org/xerial/sqlite-jdbc/issue/51/javasqlsqlexception-sqlite_misuse-library –

請發佈您用於插入數據的完整代碼。 –

你的表有四列，你的刀片只插入三個值的方法。嘗試從表格中刪除一列，或者插入一行時插入四個值。
