Jakata POI excel: get column name

Hi All
Is there a way I can get column name where a particular cell is: (In excel spreadsheet)
Ex: If I have column number 2: I should get "C" ( given col numbers are 0 based).
Please let me know.
Thanks
bib

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

  • 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.

    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.

    You shouldn't be getting column names from EJBs.
    You need to know the object, the schema, and how to map one to the other.
    So you should look at the SQL table "users" and map this object to it.

  • Getting column names empty from MS Access database

    You're here in a JDBC forum, not a SQL forum. I suggest you to start learning SQL and come back once you have JDBC issues.

    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?

  • Custom field type - get column name in code

    All,

    Greetings,
    1) Is it possible to map datatypes? i.e.
    java.util.Date to the sql timestampThe deploytool creates the mapping based on its introspection of your bean. If your bean is coded to 1.1 then it will create the mapping based on your public field types. If coded to 2.0 then it will be based on your abstract accessors (which should conform to JavaBean conventions). Also, it is better to use java.sql.Timestamp to map to SQL timestamps since most DBEs typically store such data in nanosecond precision which java.util.Date is not equipped to handle. :)
    2) Is it possible to map entity bean names and cmp
    fields to the exact database tables and column names?Yes. After you assemble your bean in the wizard, return to the 'Entity' tab and click on 'Deployment Settings' (the SDK deploytool exemplifies the distinction between Application Assembler and Deployer roles... ;). In the resulting dialog you can: specify the datasource for your bean ('Database Settings...'); edit the EJB QL for your finder/select methods ('Edit...') if not done so during assembly; and generate ('Generate Default SQL...') and edit the SQL for your particular resource. Letting the tool generate the ("default") SQL is not really very useful if your database schema is already created but it may help save some typing ':) To edit the SQL click on the method for which to edit and you can then edit (for it) in the 'SQL Query:' TextArea.
    So far I have seen no evidence of either.I hope this helps.

    If you execute the query in your program using the SqlDataReader.ExecuteReader method, the column names will be available via the GetName method of the returned reader.  But note that your query may return multiple columns with the same name.

  • Simplest way to get column names

    i need to retrieve column names in a rowset, let me explain a bit;
    i can simply retrieve a column name by using IColumnsInfo::GetColumsInfo, but the problem is when i use "AS" keyword in the select statement such like;
    SELECT identification AS  id FROM test_table_a
    i see alias name of that column instead the internal column name.
    as you can guess the qestion is; how can i get both alias and internal name at the same time and of course what is the *usual* way to get it.
