java - 数据库管理 | SQL Server 连接错误

Question

我正在尝试使用 Jasper 报告向我的系统生成一些报告。我正在使用基本的 JDBC 连接方法来建立与 SQL Server 2000 的连接。这是我的代码片段:

public static Connection getConnection()throws ClassNotFoundException, SQLException 
{
    Class.forName(driver);
    Connection conn = DriverManager.getConnection(connectString, user, password);
    return conn;
}

但是我收到 SQL 语法错误异常。

Caused by: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Line 2: Incorrect syntax near '|'.

谢谢。

Answer 1

您收到的异常的第一行显示:

 Line 2: Incorrect syntax near '|'.

检查“|”的位置在你的来源中。如有疑问，请尝试以下操作:

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); 
conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433", user, password);

还要确保您的 jar 位于正确的位置。
