java.sql.SQLException [Microsoft] [ODBC SQL Server驱动程序] [SQL Server]无效的对象名“表名”

Question

When I connect Java to Mssql using JDBC ODBC driver

try 
{
    ps=conn.prepareStatement("UPDATE products SET stock=? WHERE id=?");

    ps.setInt(1, prods.getStock());
    ps.setInt(2, prods.getId());

    int b = ps.executeUpdate();

    if(b!=0)
    {
        System.out.println("success");
    }
    else
    {
        System.out.println("Fail");
    } 
}
catch(SQLException e)
{
    System.out.println(e);
}

This catch block rises this exception

java.sql.SQLException [Microsoft] [ODBC SQL Server Driver]
  [SQL Server] Invalid object name 'products'

I am working on this part from last 2 days. How I will solve this exception?

Answer 1

This error message is thrown when the table can't be found. That can have several reasons:

• you are connecting to a different DB
• the table was deleted
• the table is in another DB schema
• your user does not have read permissions on that table any more

Answer 2

I'd imagine that your connection string has no default database - you are probably connecting to 'master' in which case the above won't work

You can test this by qualifying your query with the database and schema name:

eg

ps=conn.prepareStatement("UPDATE [YourDatabaseName].[schema].products SET stock=? WHERE id=?"); 

put your values in where needed (standard default schema is 'dbo' eg. ProductsDatabase.dbo.products)

If this works then your connection string is incorrect

Answer 3

Normally this exception is thrown if the table does not exist, or that there is an error with the connection string. Maybe not connecting to the correct database?

Answer 4

I ran into similar issue. Cause of the issue in my case was the user running the report has the DEFAULT_DATABASE pointing to the master database, after changing it to the right database it was able to locate the object.
