How to merge tables in a Dataset - Sql Server

DataSet ....

The DataSet contains copy of the data we requested through the SQL statement. The SqlDataAdapter object allows us to populate DataTable in a DataSet. We can use Fill method in the SqlDataAdapter for populating data in a Dataset. We can populate Dataset with more than one table at a time using SqlDataAdapter Object. The DataTableCollection contains zero or more DataTable objects.

In some situation we want to combine the result of multiple SQL query as a single result set. In that case we can use the Dataset's Merge method for doing this. The tables involved in the merge should be identical, that is the columns are similar data types .


Private Sub GetUsersList()

Dim connetionString As String
Dim connection As SqlConnection
Dim command As SqlCommand
Dim adapter As New SqlDataAdapter
Dim ds As New DataSet
Dim dt As DataTable
Dim firstSql As String
Dim secondSql As String
Dim i As Integer
connetionString = "Data Source=.;Initial Catalog=Nafex;User ID=sa;Password=111"
firstSql = "Select * from tblUser"
secondSql = "Select * from tluVrType"
connection = New SqlConnection(connetionString)
Try
connection.Open()
command = New SqlCommand(firstSql, connection)
adapter.SelectCommand = command
adapter.Fill(ds, "Table(0)")
adapter.SelectCommand.CommandText = secondSql
adapter.Fill(ds, "Table(1)")
adapter.Dispose()
command.Dispose()
connection.Close()

ds.Tables(0).Merge(ds.Tables(1))
dt = ds.Tables(0)

For i = 0 To dt.Rows.Count - 1
MsgBox(dt.Rows(i).Item(0) & " -- " & dt.Rows(i).Item(1))
Next
Catch ex As Exception
MsgBox("Can not open connection ! ")
End Try

String Format for Double ( 0.00)

String Format for Double [C#]

The following examples show how to format float numbers to string in C#. You can use static method String.Format or instance methods double.ToString and float.ToString.

Digits after decimal point

This example formats double to string with fixed number of decimal places. For two decimal places use pattern „0.00“. If a float number has less decimal places, the rest digits on the right will be zeroes. If it has more decimal places, the number will be rounded.

[C#]

// just two decimal places
String.Format("{0:0.00}", 123.4567);      // "123.46"
String.Format("{0:0.00}", 123.4);         // "123.40"
String.Format("{0:0.00}", 123.0);         // "123.00"

Next example formats double to string with floating number of decimal places. E.g. for maximal two decimal places use pattern „0.##“.

[C#]

// max. two decimal places
String.Format("{0:0.##}", 123.4567);      // "123.46"
String.Format("{0:0.##}", 123.4);         // "123.4"
String.Format("{0:0.##}", 123.0);         // "123"

Digits before decimal point

If you want a float number to have any minimal number of digits before decimal point use N-times zero before decimal point. E.g. pattern „00.0“ formats a float number to string with at least two digits before decimal point and one digit after that.

[C#]

// at least two digits before decimal point
String.Format("{0:00.0}", 123.4567);      // "123.5"
String.Format("{0:00.0}", 23.4567);       // "23.5"
String.Format("{0:00.0}", 3.4567);        // "03.5"
String.Format("{0:00.0}", -3.4567);       // "-03.5"

Thousands separator

To format double to string with use of thousands separator use zero and comma separator before an usual float formatting pattern, e.g. pattern „0,0.0“ formats the number to use thousands separators and to have one decimal place.

[C#]

String.Format("{0:0,0.0}", 12345.67);     // "12,345.7"
String.Format("{0:0,0}", 12345.67);       // "12,346"

Zero

Float numbers between zero and one can be formatted in two ways, with or without leading zero before decimal point. To format number without a leading zero use # before point. For example „#.0“ formats number to have one decimal place and zero to N digits before decimal point (e.g. „.5“ or „123.5“).

Following code shows how can be formatted a zero (of double type).

[C#]

String.Format("{0:0.0}", 0.0);            // "0.0"
String.Format("{0:0.#}", 0.0);            // "0"
String.Format("{0:#.0}", 0.0);            // ".0"
String.Format("{0:#.#}", 0.0);            // ""

Align numbers with spaces

To align float number to the right use comma „,“ option before the colon. Type comma followed by a number of spaces, e.g. „0,10:0.0“ (this can be used only in String.Format method, not in double.ToString method). To align numbers to the left use negative number of spaces.

[C#]

String.Format("{0,10:0.0}", 123.4567);    // "     123.5"
String.Format("{0,-10:0.0}", 123.4567);   // "123.5     "
String.Format("{0,10:0.0}", -123.4567);   // "    -123.5"
String.Format("{0,-10:0.0}", -123.4567);  // "-123.5    "

Custom formatting for negative numbers and zero

If you need to use custom format for negative float numbers or zero, use semicolon separator „;“ to split pattern to three sections. The first section formats positive numbers, the second section formats negative numbers and the third section formats zero. If you omit the last section, zero will be formatted using the first section.

[C#]

String.Format("{0:0.00;minus 0.00;zero}", 123.4567);   // "123.46"
String.Format("{0:0.00;minus 0.00;zero}", -123.4567);  // "minus 123.46"
String.Format("{0:0.00;minus 0.00;zero}", 0.0);        // "zero"

Some funny examples

As you could notice in the previous example, you can put any text into formatting pattern, e.g. before an usual pattern „my text 0.0“. You can even put any text between the zeroes, e.g. „0aaa.bbb0“.

[C#]

String.Format("{0:my number is 0.0}", 12.3);   // "my number is 12.3"
String.Format("{0:0aaa.bbb0}", 12.3);          // "12aaa.bbb3"

Adding Row Number to SQL SELECT result

ntroduction This article will explain how we can add sequence row number to a SQL select query starting from 1 onwards. This can be achieved by using built in SQL function ?ROW_NUMBER()?. This function simply generates row number for each row in the result. You can specify the partition and order by criteria. This is how it works:

e.g. Suppose we have a table ?Employees?.

SELECT EmployeeId, EmployeeName, Salary
   FROM Employees

EmployeeId   EmployeeName     Salary
-------------------------------------
1002         Alden            4000
2343         Lawson           4500
2004         Barbra           4800
1105         Marsden          4500
3116         Mac              5000

Use of ROW_NUMBER() will assign sequence number to rows as:

SELECT ROW_NUMBER()
       OVER (ORDER BY EmployeeName) AS Row,
   EmployeeId, EmployeeName, Salary
FROM Employees

Row   EmployeeId   EmployeeName     Salary
-------------------------------------------
1     1002         Alden            4000
2     2343         Lawson           4500
3     2004         Barbra           4800
4     1105         Marsden          4500
5     3116         Mac              5000

Using ROW_NUMBER() for calculating Nth highest salary

We can utilize this function for calculating Nth highest salary of a employee. Suppose we want to find employee with 4th highest salary. This can be done as:

SELECT * FROM
   (SELECT ROW_NUMBER()
       OVER (ORDER BY Salary) AS Row,
       EmployeeId, EmployeeName, Salary
   FROM Employees) AS EMP
WHERE Row = 4

Row   EmployeeId   EmployeeName     Salary
-------------------------------------------
4     1105         Marsden          4500

Using ROW_NUMBER() in case of pagination

This can also be used for getting rows which belongs to a particular page only. This is very common scenario of a business application where we have lots of rows in database and we want to filter based on page number.

SELECT * FROM
   (SELECT ROW_NUMBER()
       OVER (ORDER BY EmployeeName) AS Row,
       EmployeeId, EmployeeName, Salary
   FROM Employees) AS EMP
WHERE Row BETWEEN 2 AND 4

Row   EmployeeId   EmployeeName     Salary
-------------------------------------------
2     2343         Lawson           4500
3     2004         Barbra           4800
4     1105         Marsden          4500

Using the CASE expression instead of dynamic SQL in SQL Server

Problem
I have a lot of SQL update queries where I need to make IF/ELSE types of decisions. I am using a cursor in some cases but looping through thousands of rows for update takes a long time. I also use some dynamic SQL to handle some query parameter decision making. Is there a better alternative?

Solution
The CASE expression is a really powerful tool that can you use to solve your SQL Server query problems. You're probably familiar with its use in mimicking if/else processing when issuing SELECT statements. However, its use is not confined strictly to this kind of processing.

Among the ways I've leveraged the CASE expression in my code:

• To eliminate a cursor loop when updating rows
• To perform specialized processing when using aggregate functions
• To create dynamic ORDER BY and WHERE clauses without using dynamic SQL

Let's look at some examples

We'll first create a new table called Customer and insert some rows

CREATE TABLE dbo.Customer ( customerid INT IDENTITY PRIMARY KEY, firstname VARCHAR(40) NOT NULL, lastname VARCHAR(40) NOT NULL, statecode VARCHAR(2) NOT NULL, totalsales money NOT NULL DEFAULT 0.00 ) INSERT INTO dbo.Customer (firstname, lastname, statecode, totalsales) SELECT 'Thomas', 'Jefferson', 'VA', 100.00 INSERT INTO dbo.Customer (firstname, lastname, statecode, totalsales) SELECT 'John', 'Adams', 'MA', 200.00 INSERT INTO dbo.Customer (firstname, lastname, statecode, totalsales) SELECT 'Paul', 'Revere', 'MA', 300.00 INSERT INTO dbo.Customer (firstname, lastname, statecode, totalsales) SELECT 'Ben', 'Franklin', 'PA', 400.00 GO

Example 1
A requirement has come in to denormalize the table for reporting purposes by adding a state description column. Now, you could use a cursor and loop through the table, updating each row, but cursors can be performance killers. You could also create multiple UPDATE statements, but that would be unwieldly. Instead, you can use an UPDATE statement with CASE to efficiently update the table with one SET operation.

ALTER TABLE dbo.Customer ADD statedescription VARCHAR(50) NULL GO UPDATE dbo.Customer SET stateDescription = CASE WHEN statecode = 'MA' THEN 'Massachusetts' WHEN statecode = 'VA' THEN 'Virginia' WHEN statecode = 'PA' THEN 'Pennsylvania' ELSE NULL END

Example 2
A second requirement has come in where we need to report on the total number of all customers, the total number of all Massachusetts customers, and an average of all sales made by all Massachusetts customers. We could limit the query to just Massachusetts customers but that would make it cumbersome to get our count of total customers. To solve this problem, you can write the query to use a CASE expression within the aggregate functions to get Massachusetts specific information:

SELECT COUNT(*) AS TotalCustomers, SUM(CASE WHEN statecode = 'MA' THEN 1 ELSE NULL END) AS TotalMassCustomers, AVG(CASE WHEN statecode = 'MA' THEN totalsales ELSE NULL END) AS TotalMassSales FROM dbo.Customer

Since NULL values are discarded when performing aggregate functions, we can easily get the required totals.

Windows Live multi Messenger 2009

The support for multi-WLM is not enabled by default, but can be easily turned on and enable with registry hack.

1. Run Registry Editor (regedit).

2. Navigate to the following registry key :
KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Live\Messenge

For 64-bit (x64) OS, go to following registry branch instead:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows Live\Messenger

3. In the right pane, right click on any blank space, select New on context menu, and then click on DWORD (32-bit) Value.

4. Name the new registry value entry as MultipleInstances.

5. Modify the MultipleInstances and set its value data as 1.

6. Start as many Windows Live Messenger windows as you want from Start Menu.

Note that you need a different Windows Live account (MSN Passport user name) and password in order to run two or more instances of Windows Live Messenger. If you have set automatically login upon running WLMessenger, an error may pop up when additional instance is run if your login is still signed in when new instance opening. Just change to your second WL Messenger login.
