SQL SERVER – Simple Example of Recursive CTE

http://blog.sqlauthority.com/2008/07/28/sql-server-simple-example-of-recursive-cte/

Recursive is the process in which the query executes itself. It is used to get results based on the output of base query. We can use CTE as Recursive CTE (Common Table Expression). You can read my previous articles about CTE by searching at http://search.SQLAuthority.com .

Here, the result of CTE is repeatedly used to get the final resultset. The following example will explain in detail where I am using AdventureWorks database and try to find hierarchy of Managers and Employees.

USE AdventureWorks
GOWITH Emp_CTE AS (SELECT EmployeeID, ContactID, LoginID, ManagerID, Title, BirthDateFROM HumanResources.EmployeeWHERE ManagerID IS NULLUNION ALLSELECT e.EmployeeID, e.ContactID, e.LoginID, e.ManagerID, e.Title,e.BirthDateFROM HumanResources.Employee eINNER JOIN Emp_CTE ecte ON ecte.EmployeeID = e.ManagerID)SELECT *FROM Emp_CTE
GO

In the above example Emp_CTE is a Common Expression Table, the base record for the CTE is derived by the first sql query before UNION ALL. The result of the query gives you the EmployeeID which don’t have ManagerID.

Second query after UNION ALL is executed repeatedly to get results and it will continue until it returns no rows. For above e.g. Result will have EmployeeIDs which have ManagerID (ie, EmployeeID of the first result).  This is obtained by joining CTE result with Employee table on columns EmployeeID of CTE with ManagerID of table Employee.

This process is recursive and will continue till there is no ManagerID who doesn’t have EmployeeID

Add Identity Column to Table Based on Order of Another Column

http://blog.sqlauthority.com/2013/05/30/sql-server-add-identity-column-to-table-based-on-order-of-another-column/

I already have existing table and the table already have fewer columns. The table does not have identity column and I would like to add an identity column to this table. The problem is that every time when I try to add an identity column to the table, it adds the value based on the default order of the table. I would like to add the identity value based on the order sequence of another column from the table. Do you have any alternative to it. To illustrate my problem here is the simple script based on my table schema. My table also do not have any index as of now.

USE tempdb
GO-- Create TableCREATE TABLE TestTable (Col1 INT, Col2 VARCHAR(100))GO-- Insert DataINSERT INTO TestTable (Col1, Col2)VALUES (33, 'Pinal');INSERT INTO TestTable (Col1, Col2)VALUES (22, 'Nupur');INSERT INTO TestTable (Col1, Col2)VALUES (11, 'Shaivi');GO-- Select DataSELECT *FROM TestTable
GO-- Add Identity ColumnALTER TABLE TestTableADD ID INT IDENTITY(1, 1)GO-- Select DataSELECT *FROM TestTable
GO-- Clean upDROP TABLE TestTable
GO

Here is the result set of the query above. Currently the result is ordered by the column Col1 DESC but ideally I would like to get the result ordered by Col1 but in ASC order.

Is there any workaround to do the same?”

As I said I find this question very interesting and I was able to come up with the solution as well fairly quickly as the user had not created an index on the table. I quickly created clustered index in ASC order on Col1 and it ordered the table as expected and later added the identity column there. Let us see the script to get the desired result.

USE tempdb
GO-- Create TableCREATE TABLE TestTable (Col1 INT, Col2 VARCHAR(100))GO-- Insert DataINSERT INTO TestTable (Col1, Col2)VALUES (33, 'Pinal');INSERT INTO TestTable (Col1, Col2)VALUES (22, 'Nupur');INSERT INTO TestTable (Col1, Col2)VALUES (11, 'Shaivi');GO-- Select DataSELECT *FROM TestTable
GO-- Create Clustered Index on Column IDCREATE CLUSTERED INDEX IX_TestTable ON dbo.TestTable(Col1 ASC)GO-- Add Identity ColumnALTER TABLE TestTableADD ID INT IDENTITY(1, 1)GO-- Select DataSELECT *FROM TestTable
GO-- Clean upDROP TABLE TestTable
GO

Above script will produce following answer which user is expecting:

Now here is my question back to, this was fairly simple for me to do as there was no index created on the table. I was able to create clustered index on the column and get the desired result. However, what will be the alternative solution to this question if the clustered index is already created on the table and there was no option to modify the same. Another alternative solution would be to drop the table and do processing but that is never a good solution as well, it is not possible if there are foreign keys exists on the table

Reporting Services

17-2 Introduction to SQL Server 2008 Copyright © 2009 Accelebrate, Inc

For many years, SQL Server did not have a good answer for creating attractive

reports that summarize information in ways that make sense to business users.

Finally, Microsoft shipped SQL Server Reporting Services. Like Notification

Services, Reporting Services was originally an add-on for SQL Server 2000, and now

it’s a part of the core product. In this chapter, you’ll learn how to use Reporting

Services to produce your own reports.

The Reporting Services Architecture

Reporting Services has a quite a few components that work together seamlessly to

provide a complete reporting solution. The full Reporting Services architecture

includes development tools, administration tools, and report viewers. There are a

number of ways to get to Reporting Services programmatically, including URL,

SOAP and WMI interfaces.

Figure 17-1 shows a simplified diagram of the main Reporting Services components

that we’ll be using in this chapter.

Figure 17-1: Report Server architecture

In this chapter you’ll learn about these components:

•

Report Server is the core engine that drives Reporting Services.

•

Report Manager is a Web-based administrative interface for Reporting

Services.

•

Report Designer is a developer tool for building complex reports.

•

Report Builder is a simplified end-user tool for building reports.

Using

Report Designer

Copyright © 2009 Accelebrate, Inc. Introduction to SQL Server 2008 17-3

•

The Report Server database stores report definitions. Reports themselves can

make use of data from many different data sources.

Using Report Designer

Reporting Services includes two tools for creating reports:

•

Report Designer can create reports of any complexity that Reporting Services

supports, but requires you to understand the structure of your data and to be

able to navigate the Visual Studio user interface.

•

Report Builder provides a simpler user interface for creating ad hoc reports,

directed primarily at business users rather than developers. Report Builder

requires a developer or administrator to set up a data model before end users

can create reports.

We’ll start our tour of Reporting Services with Report Designer. Report Designer

runs inside the Business Intelligence Development Studio shell, and offers several

ways to create reports. You can either use the Report Wizard to quickly create a

report, or you can use a set of design tools to build a report from scratch. You can

also use the design tools to modify a report created with the wizard.

Using the Report Wizard

The easiest way to create a report in Report Designer is to use the Report Wizard.

Like all wizards, the Report Wizard walks you through the process in step-by-step

fashion. You can make the following choices in the wizard:

•

The data source to use

•

The query to use to retrieve data

•

Whether to use a tabular or matrix layout for the report

•

How to group the retrieved data

•

What visual style to use

•

Where to deploy the finished report

Try It!

To create a simple report using the Report Wizard, follow these steps:

1. Launch Business Intelligence Development Studio.

2. Select File

􀁦 New 􀁦 Project.

3. Select the Business Intelligence Projects project type.

4. Select the Report Server Project Wizard template.

•

The main design window lets you view the report itself. You can see a

preview of the report, work with the report in a layout designer, or work with

the query that returns the data for the report.

•

The Solution Explorer, Output, and Properties windows are the standard

Visual Studio windows.

Modifying a Report

Now that you’ve created a report with the Report Wizard, you can modify it with

the Report Designer. If you’ve used any sort of visual report design tool in the past,

you should have no problem making changes here. Among the possibilities here:

•

You can change the available data or the sort order for the report by

modifying the query.

•

You can resize or rearrange controls on the Design tab.

•

You can use the Properties window to change properties of individual

controls including their font, alignment, colors, and so on.

Try It!

To modify the report that you just created, follow these steps:

1. Click the Design tab to make the report editable.

2. In the Report Data window, right-click on DataSet1 and select Dataset

Properties.

3. In the Dataset Properties window, click the Query Designer button.

4. Select a Descending sort type for the

ListPrice column and click OK.

5. Click OK.

6. Click in the textbox at the top of the report, where the report name is displayed.

of this control to

Products By Color.

8. Click on the header for the

Product column.

9. Place the cursor between the column selectors above the

Name and Product

Number

columns to display a double-headed arrow. Hold down the mouse

button and drag the cursor to the right to widen the

Name column.

Publishing a Report

Creating reports in Business Intelligence Development Studio is good for

developers, but it doesn’t help users at all. In order for the reports you build to be

available to others, you must publish them to your Reporting Services server. To

publish a report, you can use the Build and Deploy menu items in Business

Intelligence Development Studio. Before you do this, you need to check the project’s

configuration to make sure that you’ve selected an appropriate server for the

deployment.

Publishing

You can publish any report, but the first report you created is probably more

visually interesting at this point. To publish the first report, follow these steps:

1. Select File

􀁦 Recent Projects and choose your ProductReport1 project.

2. Select Project

􀁦 ProductReport1 Properties.

3. Click the Configuration Manager button.

Using Report Builder

Report Designer gives you one way to create reports for Reporting Services, but it’s

not the only way. SQL Server 2008 also includes a tool directed at end users named

Report Builder. Unlike Report Designer, which is aimed at Developers, Report

Builder presents a simplified view of the report-building process and is intended for

business analysts and other end users.

Building a Data Model

Report Builder doesn’t let end users explore all of a SQL Server database. Instead, it

depends on a data model: a preselected group of tables and relationships that a

developer has identified as suitable for end-user reporting. To build a data model,

you use Business Intelligence Development Studio. Data models contain three

things:

•

Data Sources connect the data model to actual data.

•

Data Source Views draw data from data sources.

•

Report Models contain entities that end users can use on reports.

Try It!

To create a data model, follow these steps:

1. If it’s not already open, launch Business Intelligence Development Studio

2. Select File

􀁦 New 􀁦 Project.

3. Select the Business Intelligence Projects project type.

4. Select the Report Model Project template.

Building a Report

Report Builder itself is a ClickOnce Windows Forms application. That means that it’s

a Windows application that end users launch from their web browser, but it never

gets installed on their computer, so they don’t need any local administrator rights on

their computer to run it. To get started with Report Builder, browse to your

Reporting Services home page. Typically, this will have a URL such as

Reporting Services

17-16 Introduction to SQL Server 2008 Copyright © 2009 Accelebrate, Inc

http://

ServerName/Reports (or http://localhost/Reports if you're

running the browser on the same box with SQL Server 2008 itself). Figure 17-11

shows the Reporting Services home page.

Copyright © 2009 Accelebrate, Inc. Introduction to SQL Server 2008 17-19

Using Report Manager

The Web home page for Reporting Services provides a complete interface for

managing reports (as well as other objects such as data sources and models) after

they are created. This interface, known as Report Manager, is intended primarily for

database administrators, but as a developer you should know about its capabilities

for managing and modifying reports.

When you click on a report in Report Manager, you’ll see the report’s data, as shown

in Figure 17-14.

Figure 17-14: Report in Report Manager

Note that reports in Report Manager open in a tabbed interface. The four tabs allow

you to perform various functions:

•

View allows you to see the current data in the report.

Reporting Services

17-20 Introduction to SQL Server 2008 Copyright © 2009 Accelebrate, Inc

•

Properties lets you adjust such things as the report’s name, data source,

security credentials, caching, and end-user security.

•

History shows you saved snapshots of the report.

•

Subscriptions lets you create subscriptions to the report. Subscriptions allow

you to set up periodic delivery of reports to end users by e-mail or file share.

Printing and Exporting Reports

When viewing reports in the Report Manager, users can print the reports directly

from their browser. The print button in the report toolbar utilizes an ActiveX control

for client-side printing. The first time this button is clicked on a given computer, the

user is prompted to install the ActiveX control, as in Figure 17-15. After that, the

standard Windows print dialog box is displayed for the user to select a printer and

paper size, etc.

Figure 17-15: ActiveX install prompt.

Users can also export the report into any of several handy formats. Table 17-1 lists

the available export formats.

Export Format Handles

XML Creates a data file in XML format.

CSV Creates a comma-delimited text file of report data.

PDF Creates an Adobe Acrobat file with the formatted report.

MHTML Creates a Web Archive file with the formatted report.

EXCEL Creates a MS Excel spreadsheet with the formatted

report.

TIFF Creates a TIFF graphic of the formatted report.

INSERT data from Stored Procedure to Table

http://blog.sqlauthority.com/2013/05/27/sql-server-how-to-insert-data-from-stored-procedure-to-table-2-different-methods/

“How do I insert the results of the stored procedure in my table?”

This question has two fold answers – 1) When the table is already created and 2) When the table is to be created run time. In this blog post we will explore both the scenarios together.

However, first let us create a stored procedure which we will use for our example.

CREATE PROCEDURE GetDBNamesAS
SELECT name, database_idFROM sys.databases
GO

We can execute this stored procedure using the following script.

EXEC GetDBNames

Now let us see two different scenarios where we will insert the data of the stored procedure directly into the table.

1) Schema Known – Table Created Beforehand

If we know the schema of the stored procedure resultset we can build a table beforehand and execute following code.

CREATE TABLE #TestTable ([name] NVARCHAR(256), [database_ID] INT);INSERT INTO #TestTableEXEC GetDBNames-- Select TableSELECT *FROM #TestTable;

The disadvantage of this code is that if due to any reason the stored procedure returns more or less columns it will throw an error.

2) Unknown Schema – Table Created at Runtime

There are cases when we do know the resultset of the stored procedure and we want to populate the table based of it. We can execute following code.

SELECT * INTO #TestTableT FROM OPENROWSET('SQLNCLI', 'Server=localhost;Trusted_Connection=yes;','EXEC tempdb.dbo.GetDBNames')-- Select TableSELECT *FROM #TestTableT;

The disadvantage of this code is that it bit complicated but it usually works well in the case of the column names are not known.

Just note that if you are getting error in this method enable ad hoc distributed queries by executing following query in SSMS.

sp_configure 'Show Advanced Options', 1
GORECONFIGUREGOsp_configure 'Ad Hoc Distributed Queries', 1
GORECONFIGUREGO
