在 getTables() 方法中的何处指定数据库名称。

Where do I specify the database name in the getTables() method.

getTables() 方法未返回数据库中存在的 table 的任何结果。我认为问题在于不知道在 ip 上查看哪个数据库。当我有多个具有相同 table 的数据库时,如何指定 getTables() 方法应该查找的数据库?

         //concatinating strings for IP to hit
        String ArchiveDB_URL = "jdbc:sqlserver://" + getArchiveIPaddress();


        //  Database credentials
        String USER = "Removed";
        String PASS = "Removed";

        Connection archiveConn = null;
        Statement archiveStmt = null;

        try {

            // Register JDBC driver
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

            // Open a connection   

            archiveConn = DriverManager.getConnection(ArchiveDB_URL, USER, PASS);

            DatabaseMetaData dbm = archiveConn.getMetaData();
            ResultSet rsTBmd = dbm.getTables(null,null, "[myDatabase].[dbo].[myTable]", new String[] {"TABLE"});

            System.out.println(rsTBmd.getString("TABLE_NAME"));

             if (rsTBmd.next()){
               //result sets start at 1 not 0
               int rsTBmdi = 1;  
               while(rsTBmd.next()){
                   System.out.println(rsTBmd.getString(rsTBmdi));
                   rsTBmdi++;
               }
           }

尝试在 ArchiveDB_URL

中添加数据库名称
String ArchiveDB_URL = "jdbc:sqlserver://" + getArchiveIPaddress() + "/yourDatabaseNameHere";

getTables 的前两个参数是 catalogschemaPattern。 "Catalog" 是 "Database" 的另一个名称,因此只需提供数据库名称作为第一个参数:

ResultSet rsTBmd = dbm.getTables("myDatabase", "dbo", "myTable", new String[] {"TABLE"});

请注意,在这种情况下,您 不会 将名称括在方括号中,即使它们包含空格或 "funny characters".

根据 Microsoft,你的 JDBC URL 看起来像 "jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks;user=UserName;password=*****";,使你的代码:

    //  Database credentials
    String USER = "Removed";
    String PASS = "Removed";

    Connection archiveConn = null;
    Statement archiveStmt = null;

    try {

        // Register JDBC driver
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

        // Open a connection   
     //concatinating strings for IP to hit
    String ArchiveDB_URL = "jdbc:sqlserver://" + getArchiveIPaddress() + ";database=myDatabase;username="+USER+";password="+PASS;

        archiveConn = DriverManager.getConnection(ArchiveDB_URL);

        DatabaseMetaData dbm = archiveConn.getMetaData();
        ResultSet rsTBmd = dbm.getTables(null,null, "[myDatabase].[dbo].[myTable]", new String[] {"TABLE"});

        System.out.println(rsTBmd.getString("TABLE_NAME"));

         if (rsTBmd.next()){
           //result sets start at 1 not 0
           int rsTBmdi = 1;  
           while(rsTBmd.next()){
               System.out.println(rsTBmd.getString(rsTBmdi));
               rsTBmdi++;
           }
       }

我希望这对您有所帮助...
