Getting column names for a particular Table from Connection object.

Hi,
Can any one suggests me a way to get column names from a particular table of a database from the java.sql.Connection object. ?
Thanks in advance.

Connection connection;
DatabaseMetaData metadata = connection.getMetaData();
String[] names = {"TABLE"};
ResultSet tables = metadata.getTables(null,"%", "%", names);
while (tables.next()) {
String tableName = tables.getString("TABLE_NAME");
ResultSet columns = metadata.getColumns(null, "%", tableName, "%");
while (columns.next()) {
String columnName = columns.getString("COLUMN_NAME");
}

How do you get the column names for a given table from an SQL LocalDB programmatically in Visual Basic.

Just new to this and unable to find answers

My solution
    Public Function GetTableColumnNames() As Boolean
        Form1.ListBox1.Items.Clear()
        _MDFFileName = String.Format("{0}.mdf", _DatabaseName)
        _sqlConnectionString = String.Format("Data Source=(LocalDB)\v11.0;AttachDBFileName={1};Initial Catalog={0};Integrated Security=True;", _DatabaseName, Path.Combine(_DatabaseDirectory, _MDFFileName))
        Dim cn As New SqlConnection(_sqlConnectionString)
        'put the table name in brackets in case it has spaces in it
        Dim SQLString As String = "SELECT * FROM [" & _TableName & "]"
        Try
            cn.Open()
            Dim cmd As New SqlCommand(SQLString, cn)
            Dim rdr As SqlDataReader =
            cmd.ExecuteReader(CommandBehavior.KeyInfo)
            Dim tbl As DataTable = rdr.GetSchemaTable
            'This shows all of the information you can access about each column.
            For Each col As DataColumn In tbl.Columns
                Form1.ListBox1.Items.Add(col.ColumnName)
                Debug.Print("col name = " & col.ColumnName & ", type = " & col.DataType.ToString)
            Next
            'Get each column.
            For Each row As DataRow In tbl.Rows
                Form1.ListBox1.Items.Add(row("ColumnName"))
            Next
            rdr.Close()
        Catch
            MessageBox.Show("Error opening the connection to the database.")
        Finally
            cn.Close()
        End Try
        Return _Success

In The Same way Hw We Get the Relation ship for All other columns In the Controller Cllass ..
Can Any One Reply as It is urgent Req...
Thanks ,,
Jithen

Instead of using the VO attribute names to set and get values, best to go to the VO definition, click on Java, and generate the View Row Class with the accessors.
In the class where you're trying to set attributes, instead of a Row class, use the View Row class of your VO (eg ViewObjectName's class would be ViewObjectNameRowImpl), and when retrieving a row from the VO, cast the row to the previously mentioned View Row Class.
At that point you can use the View Row Class's methods that would perform sets and gets of each column.
To get attribute names, I don't know off the top of my head, but there might be a method mentioned in the Javadoc for the ViewRowImpl or ViewObject or ViewObjectDefinition classes to get the attribute/column mapping, or perhaps you can somehow read the XML definition of the VO which has that mapping.
Assuming business components were built automatically and no attribute names were overridden, intuitively the attribute name is a camelcase version of the column name, removing understores and capitalizing the character following the removed underscore - but that's not a fool proof approach. Just a general observation.
Hope this helps.

Getting column names for a Query resultList?

For a Query created via EntityManager.createQuery("some qlString here"), where the query language string picks out individual properties (so select p.firstName, p.lastName from Person p), is there any way to get the property names of the things retrieved?
I'm trying to allow an end user to define JPA queries by storing the query language string persistently, and then (after some rudimentary checking) create a Query from it, hosted (at this point) in a JTable. It would be nice if there were a way to wire up the items returned by the query such that the JTable columns were "titled" with something appropriate.
Otherwise I have to either (a) parse the QL string (yuck yuck yuck) or (b) somewhat redundantly have the user specify the columns/properties/related objects that they think they're retrieving.
Thanks,
Laird

Why do I get a class conflict between the Prepare SQL.vi and the Get Column Name.vi with the SQL Toolkit compatibility vis from the Database Connectivity Toolkit?

I have done extensive programming with the SQL Toolkit with LabVIEW versions through 6.1. My customer now wants to upgrade to Windows 7, so I am trying to upgrade to LabVIEW 2009 (my latest purchased version) using the Database Connectivity Toolkit, and the SQL Toolkit Compatibility vis. Everything seemed to be going okay with the higher level SQL operations, but I ran into trouble with the Get Column Name.vi.
The pictures below show the problem. The original SQL Toolkit connected the Prepare SQL.vi with the Get Column Name.vi with a cluster of two references, one for connection, and one for sql. The new compatibility vis have a class conflict in the wire because the Prepare SQL.vi contains a cluster with connection, and command references, but the Get Column Name.vi expects a cluster with connection and recordset references.
How do I resolve this conflict?
Thank You.
Dan

I've never worked with the old version of the toolkit, so I don't know how it did things, but looking inside the SQL prep VI, it only generates a command, and the the column name VI wants a recordset. I'm not super familiar with all the internals of ADO, but my understanding is that is standard - you only have the columns after you execute the command and get the recordset back. What you can apparently do here is insert the Execute Prepared SQL VI in the middle and that will return what you need.
I'm not sure why it worked before. Maybe the execute was hidden inside the prep VI or maybe you can get the column names out of the command object before execution. In general, I would recommend considering switching to the newer VIs.
Try to take over the world!

Return the column names for which the row values are not null.

Hi i m a new guy to db admin, and i need a sql script which should return column names of the particular table. and the returned column should have value (fyi - if the column has null value column name should not come in the sql o/p).
Exmple:
table name - A
s.no name mark status fee
1 aa 45 p null
2 bb 30 null paid
3 cc 35 p paid
fyi -1) if i give the table name(A) and s.no (2) the o/p should be -- name,mark.
2) if i give the tablename(A) and s.no (1) the o/p should be --- name,mark,status.
Thanks
Krishna.

BTW,
The previous solution is for all values of the column, if you want a specific row, you can add it in where clause.
I mean in your example, it you look like:
SET serveroutput on;
DECLARE
   l_cnt          NUMBER;
   l_str          VARCHAR2 (255) := '';
   l_table_name   VARCHAR2 (255) := 'YOUR_TABLE_NAME';
   l_col_cond     VARCHAR2 (255) := 'S_NO';
   l_val          NUMBER         := 1;
   CURSOR c_col
   IS
      SELECT column_name
        FROM user_tab_columns
       WHERE table_name = l_table_name;
BEGIN
   FOR i IN c_col
   LOOP
      EXECUTE IMMEDIATE    'SELECT COUNT ('
                        || i.column_name
                        || ') FROM '
                        || l_table_name
                        || ' WHERE '
                        || l_col_cond
                        || ' = '
                        || l_val
                   INTO l_cnt;
      l_str := l_str || CASE
                  WHEN l_cnt = 0
                     THEN ''
                  ELSE i.column_name
               END || ',';
   END LOOP;
   l_str := SUBSTR (l_str, 1, LENGTH (l_str) - 1);
   DBMS_OUTPUT.put_line (l_str);
END;Saad,

How to use get column name.vi in SQL toolkit 2.0?

Due to the vi "get column name.vi" paremeters,no table name has connected to the vi. So, I want to ask how to use this vi for gain one column name of a table. Maybe there are some other ways to solve column name getting.
Thanks.

Thanks!
Error 4101 Description:
Execute SQL - The connection, statement, or query handle you provided is not valid.
I don't just used the toolkit in a while,now, I am developing a irrigation system. For the table field names defined by users,column names must be known before any select operations. Do you have any other good idea about drawing out the columnname parameters?
As you know, a valid DSN and table have been also available. The database I used is Access. The bad thing to me is that there is no any text information gotten. And I think, it may be some problems in connection way which I don't find out.
Really appreciated by your reply.
Could you give me some example in the aspect?
Thank you again.

It's not as easy as it might seem, since the letter sequence system is not compatible with common numeric sequence system.
