因此，在過去的幾個小時裏，我一直在嘗試建立一個數據庫，然後在Java Servlet中使用數據庫作爲DataSource（我正在使用Netbeans）。出於某種原因，當我嘗試執行「Insert into Accounts（Email，Hash，Salt）values（xyz，xyz，xyz）」語句時，我不斷收到錯誤「Invalid object name'Accounts' ，因爲我絕對有表在我的數據庫jdbc：「無效的對象名'[table name]'。」
我使用SQL Server 2016
我context.xml文件設置如下：
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/opdracht2">
<Resource auth="Container"
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
logAbandoned="true"
maxActive="8"
maxIdle="4"
name="jdbc/H4O"
password="secret"
removeAbandoned="true"
removeAbandonedTimeout="60"
type="javax.sql.DataSource"
url="jdbc:sqlserver://DESKTOP-PS13CKQ;integratedSecurity=true"
username="DESKTOP-PS13CKQ\MemeMeister"/>
</Context>
當我運行下面的代碼看看有什麼表格：
Connection connection;
connection = dataSource.getConnection();
DatabaseMetaData md = connection.getMetaData();
ResultSet rs = md.getTables(null, null, "%", null);
ResultSet rs2 = md.getSchemas();
while (rs.next()) {
System.out.println("rs.getString(3));
}
System.out.println("------Schemas-----");
while (rs2.next()) {
System.out.println(
rs2.getString("TABLE_SCHEM")
+ ", "+rs2.getString("TABLE_CATALOG"));
}
我得到以下輸出：

的架構DBO就在那裏，但沒有我的表似乎是在列表中。這裏有幾個SSMS截圖：
如果有人可以幫助我解決問題，這將是偉大的！
--edit-- 在SQL服務器配置管理器中，我有以下錯誤; 
它只是一個提示，但您可能必須在表名稱前添加數據庫名稱。例如：H40。帳戶 –
@BalázsNemes感謝您的提示！但是，這給出了同樣的錯誤，但它現在說'H4O.Accounts'，而不是對象'賬戶'。 – ImJustACowLol
它看起來像Accounts是在dbo模式下。你能查詢H40.dbo.Accounts嗎？ – phatfingers
