Reading From A DataSet
May 29, 2008
How do I address specific fields within a Dataset? I have built the DataSet from an SQL SELECT and now need to grab some of the data. I am a bit confused. Here is a code snippet (C#) but the compiler complains about my arrays. Can anyone offer a suggestion or two?
using (SqlConnection config = new SqlConnection(configString))
{
SqlConnection con = new SqlConnection(configString);
String selectString = "SELECT Column, FlowPoint, Label FROM CounterConfigurator";
SqlCommand cmd = con.CreateCommand();
cmd.CommandText = selectString;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataSet ds = new DataSet();
config.Open();
da.Fill(ds, "Labels");
DataTable dt = ds.Tables["Labels"];
config.Close();
/*-----------------------------------------------------------------------------
*At this point, I have filled the data table, "Labels", with the values
*from the CounterConfigurator table in the DB "Logger".
-------------------------------------------------------------------------------*/
//Labels
foreach (DataRow row in dt.Rows)
{
//lblPT1.Text = row[0][0]; The first column is the TOTAL Column.
lblPT10.Text = row[1][2];
lblPT11.Text = row[2][2];
lblPT12.Text = row[3][2];
lblPT13.Text = row[4][2];
lblPT14.Text = row[5][2];
lblPT15.Text = row[2];
lblPT16.Text = row[7][2];
lblPT2.Text = row[2];
lblPT3.Text = row[9][2];
lblPT4.Text = row[10][2];
lblPT5.Text = row[11][2];
lblPT6.Text = row[12][2];
lblPT7.Text = row[13][2];
lblPT8.Text = row[14][2];
lblPT9.Text = row[15][2];
}
//FlowPoints
foreach (DataRow row in dt.Rows)
{
//PT1 = row[0][1]; The first column is the TOTAL Column.
PT10 = row[1][1];
PT11 = row[2][1];
PT12 = row[3][1];
PT13 = row[4][1];
PT14 = row[5][1];
PT15 = row[1];
PT16 = row[7][1];
PT2 = row[1];
PT3 = row[9][1];
PT4 = row[10][1];
PT5 = row[11][1];
PT6 = row[12][1];
PT7 = row[13][1];
PT8 = row[14][1];
PT9 = row[15][1];
}
}
}

I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.

I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1:Â Small table without CLOB, 10 rows.Â
Table 2: Large table with CLOB, 10,000,000 rows
select CLOB
from table2
where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.

Hi,
I have a stored procedure attached below. It returns 2 rows in the SQL Management studio when I execute MyStorProc 0,28. But in my program which uses ADOHelper, it returns a dataset with tables.count=0.
if I comment out the line --If @Status = 0 then it returns the rows. Obviously it does not stop in
if @Status=0 even if I pass @status=0. What am I doing wrong?
Any help is appreciated.
ALTER PROCEDURE [dbo].[MyStorProc]
(
@Status smallint,
@RowCount int = NULL,
@FacilityId numeric(10,0) = NULL,
@QueueID numeric (10,0)= NULL,
@VendorId numeric(10, 0) = NULL
)
AS
SET NOCOUNT ON
SET CONCAT_NULL_YIELDS_NULL OFF
If @Status = 0
BEGIN
SELECT ......
END
If @Status = 1
BEGIN
SELECT......
END

Hi,
I have two datasets in my report, D1 and D2.
D1 is a list of classes with classid and title
D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.
I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.
Is there any way to do this in RS2005?

Using this IIF statement:
=CountDistinct(IIF(Fields!Released_DT.Value = Fields!Date2.Value, Fields!Name.Value,
Nothing))
Released_DT = a date - 09/03/2015 or 09/02/2015
Date2 = returns another date value in this case 09/03/2015
What I'm trying to do is: count distinct number of people (Fields!Name.Value) if the Relased_DT = Date2.My IIF statement is returning a zero value.

Hi experts,
I'm not sure my design is normal or not. Please give me some advice.
I've a dataset and query by a field name 'companyid'.
select * from companyid where companyid = @icompany which @icompany is a input field.
if user select all, i'll send 0 to @icompany then I need to select all records.
question 1. How can I get all records? (i think about this query select * from companyid <> 0)
if user select for example companyid = 1, i'll send 1 to @icompany and the query work fine.
question 2. How can I change the query to adopt this 2 condition?
Thanks a lot,
Jeff

Why won't this dataReader read?
Dim objCon2 As New SqlConnection()
objCon2.ConnectionString = "a standard connection string"
objCon2.Open()
Dim objCommand As SqlCommand
objCommand = New SqlCommand(strSQL, objCon2)
Dim objReader As SqlDataReader
objReader = objCommand.ExecuteReader()
Label1.Text = objReader("email")
strSQL is a select command which I've checked (using SQL Query analyzer) does return data. I know the connection string is valid (and I presume if it wasn't that it'd fail on objCon2.open, which it doesn't).
So why oh why do I get this error on the last line (and yes, there is an "email" field in the contents of the reader)
System.InvalidOperationException: Invalid attempt to read when no data is present.

I have this code that I hacked together from someone else's example. I kind of understand how it works. I just don't know if it will and i am not in a location right now to check. I was wondering if I did this correctly first, second how can it improve and should i do something different. Basically i just want to check the password in a database. I am passing the username and password to this function from another functioprivate bool authUser(string UserName, string Password){ string connectionString = ConfigurationSettings.AppSettings["DBConnectionString"]; SqlConnection DBConnection = new SqlConnection(connectionString); bool result = false; DBConnection.open() SqlCommand checkCommand = new SqlCommand("SELECT password FROM Users WHERE userName='" + Password + "', DBConnection) SqlDataReader checkDataReader = checkCommand.ExecuteReader();
if(checkDataReader.GetString(0) == Password) { result = true; } else { result = false; } checkDataReader.Close(); DBConnection.Close();
return result;}Thank you Buddy Lindsey

Is there a way, in SQL 7.0 to print out or view what's in the Transaction Log? In 6.5 you could view the table syslogs, but I don't see any documentation anywhere on how to do this in 7.0.

I received a SQL Server 6.5 database (.dat file) on a removeable drive. I'm currently running 7.0. Is there any way to read/import/link to this data without installing 6.5. And if I have to install 6.5 how do I get the system to see the database?

Hi. I want to write a function to retrieve all records from a "Parts" table so that I can read these records in .NET.
SqlDataReader reader = sqlCmd.ExecuteReader()
while( reader.Read() )
{
int x = reader["id"];
string partName = reader["name"];
// Do stuff with data here //
}
My question: How should the function be written?
Should I create a PROCEDURE and just call a SELECT statement?
CREATE PROCEDURE getPartsList()
AS
SELECT part_id as 'id', part_name as 'name' FROM parts
Or should I create a FUNCTION that returns a TABLE? If so, is this the correct syntax?
CREATE FUNCTION getPartsList()
RETURNS TABLE
AS
RETURN (SELECT part_id as 'id', part_name as 'name' FROM parts)
Thanks for reading
