Get column names into a VB program, for an SQL query that joins tables

use [mydatabase]
select * from InvNum inum
left join _btblInvoiceLines ilin
on inum.autoindex = ilin.iinvoiceid
left join stkitem s
on ilin.istockcodeid = s.stocklink where InvNumber = 'IVQ0834' or InvNumber = 'IVQ0835'
I need to get out the column names in a VB program in the same order they would appear in the SQL query above...
I want to use something like:
select column_name from information_schema.columns where TABLE_NAME = ....
except there are several tables involved above so I dont know the format!

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.
Dim reader As SqlDataReader = command.ExecuteReader()
For x = 0 To reader.FieldCount - 1
Console.WriteLine(reader.GetName(x))
Next x

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");
}

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.

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.

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.

Ex: If I have column number 2: I should get "C" ( given col numbers are 0 based).
Please let me know.

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

Why is Mail asking me for the name of an smtp server for an email address that doesn't exist?

I've migrated from Snow Leopard to Mountain Lion on a new Mac, but in trying to use Mail on ML, it keeps asking me for the name of an smtp server for an email address that's never existed. The addy has my user name correct, but the server part of the address doesn't exist, or at least I've never used an email address with that provider. On ML there's no plist file for Mail, so nothing to delete there. What else can I do to get Mail working? The only other option I have is to abandon Mail as being crippled and useless, and use Postbox, which for it's price (US$9.95) is an attractive option. OTOH, I've paid for Mail after all, so it really ought to work. Any clues as to what I can do to stop its nonsensical behaviour? How do I file a bug report?
TIA.

How to pass a variable for a SQL query in OLEDB source?

Hi All,
I am new to SSIS and working on it past few days. Can anyone please help me getting through a scenario where I need to pass a variable in the SQL statement in OLEDB source connection. Please find below for the details.
eg:
1) I have a SQL table with the columns SerialNumber, Name, IsValid, FileName with multiple rows.
2) I have the file Name in a variable called Variable1.
3) I want to read the data from my SQL table filtering based on the FileName (Variable1) within a data flow task and pull that data to the destination table.
Question: In the data flow task, added source and destination DB connection with a script component in between to perform my validations. When trying to retrieve the data from source using the variable (i.e. SQL Query with variable), I am not able to add
the query as the SQL statement box is disabled. How to filter the data based on the variable in the source DB ?
Any help/suggestions would be of great help.
Thanks,
Sri

Just to add with Vaibhav comment .
SQL Command : SQL query either with SQL variable or any condition or simple Sql statement
Like ;
Select * from dimcustomer
SQL Command using Varible :
Sometimes we design our dynamic query in variable and directly use that variable name in oledb source.
If you Sql query needs a condition based on SSIS variable .
you can find a Example here :

How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?

1. How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?
When multiple tables are involved , and the actual number of rows returned is more than what the explain plan tells. How can I find out what change is needed in the stat plan ?
2. Does rowsource statistics gives some kind of understanding of Extended stats ?

You can get Row Source Statistics only *after* the SQL has been executed. An Explain Plan midway cannot give you row source statistics.
To get row source statistics either set STATISTICS_LEVEL='ALL' in the session that executes theSQL OR use the Hint "gather_plan_statistics" in the SQL being executed.
Then use dbms_xplan.display_cursor

Looking for and SQL query to match CTI OS agent login ID with the Directory Number (instrument)

Hi All,
I am looking for an SQL query to request the HDS database to find out which Directory Number / instrument was associated with a specific CTI OS agent login ID.
Has anyone done such a query before ?
Thanks and Regards
Nick

Hi,
this should work in 8.0 and 8.5:
SELECT
ag.PeripheralNumber AS [LoginID],
al.Extension,
al.LogoutDateTime
FROM [instance]_hds.dbo.Agent_Logout al
JOIN [instance]_awdb.dbo.Agent ag ON al.SkillTargetID = ag.SkillTargetID
Of course, replace [instance] with the ICM instance.
The query returns a table with three columns, first is the login ID aka PeripheralNumber, Extension is... well, the agent's extension, and LogoutDateTime is the timestamp when the agent logged out.
