Getting Column names from SQL report

I have a SQL report as follows:
select ename, dept, manager
from emp;
I need to be able to dynamically access the column names being displayed inside APEX so I can use in a List of Values. I can't use all_tab_columns. Is there an internal APEX table/view that I can accxess that will give me all of the columns that are eing displayed in a SQL report?

Hi Bob,
Try this -
1) Give your report region a static id
2) Use the following query -
select
heading d,
column_alias r
from
apex_application_page_rpt_cols
where region_id = 'FOO';Obviously change 'FOO' to match your region id, and look at the different columns available in the apex_application_page_rpt_cols view to see what best suits you.
The APEX dictionary rocks ;)
Hope this helps,
John.

Getting column names from SYS_REFCURSOR

Hi everybody, i have a SYS_REFCURSOR in a procedure. And i open it and fetch cursor to a record as follows:
OPEN curgroup FOR vexpr2;
LOOP
FETCH curgroup INTO recType;
END LOOP;
recType is a Record, has two variables. Anyway, the question is can i get the column names from refcursor?
like recType.COLUMN1 (Column1 is not a record variable ) ????
or is there anything else to perform this operation?

Hi,
Despite what Billy states it is very possible to get the column names from a weak ref cursor, or describe a ref cursor with PL/SQL. It has been possible since 8i, it just relies on the little known fact that a ref cursor in PL/SQL translates directly to a ResultSet in Java so we can use a tiny JSP in the DB.
Here is the link to the completely free, Open Source code which allows you to do this: [XUTL_REFCURSOR|http://www.chrispoole.co.uk/apps/xutlrefcursor.htm]

How to suppress column names in SQL-report

What I want is just the data, without any column names.
COLUMN LDATE OFF;
SELECT     SYSDATE LDATE
FROM DUAL;
LDATE
07.11.11
This example doesn't work. There is still LDATE above column. Any idea?

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");
}

Getting column names using EJB3.0

Hi,
Could someone help me how to get column names in EJB3.0.
I am having reference to folloiwng ejb.
@Entity
@Table(name = "users")
@org.hibernate.annotations.Entity(dynamicInsert = true, dynamicUpdate = true)
@SequenceGenerator(name = "users", sequenceName = "users")
public class User {
private Long userId;
private String username;
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "users_seq")
@Column(name = "user_id")
public Long getUserId() {
return userId;
public void setUserId(Long userId) {
this.userId = userId;
@NotNull
@Column(name = "username")
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
Thanks in advance

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.

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.

Hi Guys, I am trying to insert data in an SQL table by executing an Insert Query.
The problem is that I need to get the column name from a cell in the selected gridview Row.
Here's the snippet:
SqlCommand cmd30 = new SqlCommand("insert into mytable ( '"+GridView7.SelectedRow.Cells[0].Text+"' , r_id) values ('"+ GridView7.SelectedRow.Cells[1].Text +"', '"+TextBox1.Text+"')",con30);
cmd30.ExecuteNonQuery();
**r_id is not a Primary Key.
The Error is get is:
Incorrect syntax near 'r_id'.
Any Help will be appreciated.
Thanks,
Shaleen

Hi TheShaleen,
Like your title mentioned.GridView control is a web class.This forum is to discuss problems of C# development. Your question is not related to the topic of this forum.

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

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.

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.

How to pull only column names from a SELECT query without running it

How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.

Maybe something like this is what you are looking for or at least will give you some ideas.
        public static DataSet MaterializeDataSet(string _connectionString, string _sqlSelect, bool _returnProviderSpecificTypes, bool _includeSchema, bool _fillTable)

Getting table name from a query

Hi, I'm trying to get the table name from my sql query
My code is as follows;
ResultSetMetaData metadata = rs.getMetaData();
for (int i = 1; i < metadata.getColumnCount(); i++)
System.out.println(metadata.getTableName(i));
I just get a blank output. Yet my sql query executes and I can pull down the records, and grab the column names from the result sets.
Any ideas on how I can get the table name for the columns. The reason being is on one of my querys I'm using join statements and i need to retrieve the table name for the column i'm displaying, as some tables have similar column names.
Thanks in advance.

Hi,
What db are you using?
I also get a blank output with ResultSetMetaData.getTableName because Oracle doesn't implement this method.
Why do you not know the table name anyway?
