Changing databases in jdbc sql server connection

Question

How to change the default database to which access connects? For example, im trying to get a list of each table on sql server connected to:

List list = new ArrayList();
for (String db: dbList) {
    conn.prepareStatement("use ["+db+"]").executeQuery();//THIS LINE ISNT WORKING D:
    DatabaseMetaData md = conn.getMetaData();
    rs = md.getTables(null, null, "%", null);
    while (rs.next())
        list.add(rs.getString(3));
}
return list;

A line that does not work causes this error:

com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.

Creating a new connection for each db is not an option.

You cannot use executeQuery()for this, you need to use execute()(and the error message gives you good advice). Use PreparedStatementalso does not make sense here.

Statement, :

Statement stmt = conn.createStatement();
stmt.execute("use [" + db + "]");
stmt.close();

() Connection.setCatalog() , 100%, Microsoft
