sql server - How to write "Tagging" query in SQL? - Stack Overflow



You will learn how to create a database, view the objects and default tables in a database, use a query editor, activate the database in different ways, and create tables in the database using a load script. This database will be used throughout the rest of the book to learn SQL, how to write sql queries in sql server 2005. sqlto your working directory on your computer, before you start working on the next section. Right-click on the script on the web site, select Save Target As, and save it to your working directory.


In this chapter, you will also learn how to view and modify table definitions; delete a table and a database; type, parse, execute and save a query; display the results in different forms; stop execution of a query; and print the query and results. From the Start menu, go to All Programs, select Microsoft SQL Serverand then SQL Server Management Studio as shown in the Figure You will get the screen shown in Figure This screen allows you to connect to Microsoft SQL Server If the server type and server name are different from the defaults that came up, enter the appropriate server type and server name, and select Windows Authentication.


Then, click Connect. Once connected to the server that you typed in, you will get the Microsoft SQL Server Management Studio screen Figure that we will be using throughout the rest of the book. The Microsoft SQL Server Management Studio screen contains the Object Explorer on the left portion of the screen and, to start with, a Summary tab on the right portion of the screen.


The Object Explorer provides a hierarchical view of objects. For example, you can navigate through a database, table, column, or other types of objects, as we will soon show you. Before we begin to work with Microsoft SQL Serverwe will create a database. To create a database, as shown in Figureright click on Databases in the Object Explorer and select New Database from the context menu. You will get the New Database dialog box, as shown in Figure Click OK. A SQL Server database is a collection of many objects, such as tables, views, and synonyms, defined to support activities performed with data.


A database is a collection of related tables. SQL Server comes with some default System databases-- mastermodelmsdband tempdb. To view these default database nodes, expand the Database node and then System Databases node, as shown in Figure how to write sql queries in sql server 2005, and you will be able to see the default System databases.


master is a database composed of system tables that keeps track of server installation as a whole and all other databases that are subsequently created. The SQL Server Management Studio query window defaults to the master database context. Any queries executed from the query window will execute in the master database unless you change the context.


model is a template database. Every time a new database is created, SQL Server makes a copy of the model database and all of the objects in it to form the basis of the new database. If you want all your new databases to inherit certain properties, you could include these properties and objects in your model database.


msdb is a database that contains the metadata and database objects used by the SQL Server agent that performs scheduled activities such as backups and replication tasks. tempdb is a temporary database or workspace recreated every time SQL Server is restarted. tempdb is used for temporary tables created by users and to hold intermediate results created internally by SQL Server during query processing and sorting.


The most important thing you do in SQL Serveror in any other database for that matter, is query the database. Queries in SQL Server are typed in the query editor. The query editor can be opened in two ways, as discussed in the following subsections: a by right-clicking, and b by using the New Query button.


Select New Query. Figure shows the query editor, which can be used to create queries and other SQL scripts and execute them against SQL Server databases.


The first query will be called SQLQuery1. how to write sql queries in sql server 2005 by default. Later we will show you how to change the name of the query when saving it.


You can also open the query editor by selecting the New Query button from the top menu leftmost iconas shown in Figure Then, click the Execute button it is on the menu bar above the query editor screen. You will get the following message in the results pane as shown in Figure :. A table is used to store data in a database, and, a database is typically composed of many tables. sqlthat you downloaded and saved to your working directory.


Then, select the whole script and copy it. Paste the load script into the query editor, as how to write sql queries in sql server 2005 in the Figure Once the script has been pasted into the query editor, execute this script by clicking the Execute button or the F5 shortcut key.


This script takes only a few seconds to execute. You will get the results shown in Figure --on the bottom part of the screen under the Messages tab. We also present the T-SQL for the load script in Appendix B. Every table how to write sql queries in sql server 2005 SQL Server has a table definition.


The table definition gives us information about a table such as the column names in the table, the data types of the columns in the table and whether the columns allow null missing values. You will be able to view the columns in the Student table.


The columns in the Student table are stnosnamemajorclassand bdate. If you wish to modify any of the column specifications—for example, if you want to insert or delete columns, rename a column, change the data type of a column, or allow or disallow null fields—you need to modify the table definition. The table definition can be modified by modifying the column definition or by modifying the table definition. To modify the column definition, right-click the column that you wish to modify.


For example, if you wish to modify the column definition of the SNAME field of the Student table, as seen in Figureright-click the SNAME field of the Student table as shown in Figureand select one of the following options—New Column, Modify, Rename, Delete, Refresh or Properties. Another way to view or modify the table definition is to right-click the table—for example, Student --and then select Modify, as shown in Figure The table definition of the Student table is now displayed, as shown in Figure You can delete or insert columns from here, change the data types, allow or disallow null values, and more.


Once you have finished making your changes or just viewing the table definition, if that is what you intended to doyou can close this window. You will be asked if you wish to save the changes and you may select Yes or No, depending on whether you made changes to the table definition and you want to save the changes.


To view the data in a table, right click on how to write sql queries in sql server 2005 table, as shown in Figureand select Open Table. For example, to view the data of the Student table, right-click on the Student table, and select Open Table. This will show all 48 rows of the Student table, of which we show the first 14 rows here:. This screen also allows you to insert data, make changes to the data, and save this changed data. To delete a table, how to write sql queries in sql server 2005, right-click on the table that you wish to delete as shown in Figureand then select Delete.


Deleting a table will delete the table, table definition, and all of the data in the table. Once you delete a table, there will be no way to get the table or its data back except by restoring from a backup. Be very careful that you indeed intend to permanently dispose of data before selecting Delete. Do not delete any tables right now.


We provide this information for later reference, should you have to delete tables. To delete a database, right-click on the database that you would like to delete, how to write sql queries in sql server 2005, and select Delete, how to write sql queries in sql server 2005, as shown in Figure Like every computer language, a SQL query or statement is used to give instructions to the computer. A query is a request for data stored in SQL Server. The computer analyzes each instruction and interprets it.


If the computer cannot figure out what the instruction means, it displays an error message. In SQL Serverthe SQL query is typed in the query editor screen, as shown in Figure But, before you type in your query, make sure the database that you wish to work with is active or open. Type the following SQL query how to write sql queries in sql server 2005 the resulting screen:.


So this is a simple SQL query that tells SQL Server to display all the rows and columns all the data in the Student table. Before you execute your query, you may parse your query. The Parse Query button is shown in Figure By parsing the query you can make sure that your query is correctly written, before you execute your query.


To execute a query, click the Execute button, shown in Figure If there are no errors in the query, the Execute button will execute run the query and the results will show on the results pane bottom partition of the screen.


The automatic color coding of SQL code in the query editor will help you type in your SQL query correctly. It will help you prevent and resolve errors. If you are using the default color codes, for example, and you type in a keyword that is not displayed in blue, the keyword is probably misspelled. If your code is displayed in red, you might have omitted a closing quotation mark for a character string.


To save a query, while the query is on the query editor screen, from the top menu, select File and Save SQLQuery1. sql As A dialog box will open up and you will be able to type the name under which you want to save your query, and you will also be able to navigate to the directory to which you want to save your query.


Results in SQL Server are displayed in the Results pane. The Results pane is shown in Figure SQL queries can be executed to view results in grid form or text form, or the results can be saved to a file, as discussed in the following subsections.
