SQL Server / TSQL Tutorial Scenario: How to Get Identity Column Values without mentioning Identity Column Name in Select You took a quick look on Table and Columns in SQL Server but could not find if Identity Property is enabled on one of the column. You don't want to use system tables to find out the column name if identity is enabled or not but want to get the column name with data. How would you do that?

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

Best Way to Write Basic SQL Queries
 
13:33
SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: http://www.joes2pros.com/joes2pros/Course/Introduction_To_Microsoft_SQL_Server Enroll Today & Get the First Month for only $1!

SQL Tutorial 5: SELECT statement
 
07:29
Use SELECT statement to display the content of column/s in an instance of a row or record in tables. SELECT [set of column names] FROM statement is one of a powerful data manipulation language (DML) commands that makes SQL. The syntax of this statement is standardized either you are using DB2, MySQL, Informix, Oracle, or SQL Server. Issue asterisk (*) or star if you want to display all data inside a table. A table may contain a thousand or millions of record. In order to display specific criterion that you search, issue a WHERE clause that specifies the filter condition. WHERE clause works effectively with comparison operators such as greater than, less than, equal to, greater than equal, less than equal, or NOT EQUAL operators. Use BETWEEN-AND if you a filtering amount or date ranges. The IN operator filters only specific string of column data that you may want in your listing. Logical operators such as AND, OR, NOT may be used if you have a compound filtering conditions. To understand fully on how this is formed to may a powerful SELECT statement, the video shows specific problems with solutions on how to solve a given selection criteria. Included in the examples are filtering using specific data with IN operator, filtering a set of range amount with BETWEEN AND combination, and with comparison operators. Link for the ebook will be announced later.

There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

SQL Tutorial 6: SELECT with LIKE clause and ALIAS to column
 
06:48
In addition with clauses that you could combine with SELECT statement, the video shows examples using LIKE, BETWEEN AND in filtering dates, setting an ALIAS name for a column, and deriving a column as a result of a computation. YEAR function is used to derive the year of date column. Use LIKE clause in filtering string pattern in a column. Use may filter rows or records with a last name that starts with SM or ends with TH or an ER pattern in between. This is use either with a percent sign (%) or underscore (_). BETWEEN AND clause is not limited in amount ranges. You may use this powerful clause when limiting specific date range. On most occasions, you may opt to use a different column name or an ALIAS when displaying the column. Use AS operator in column name together with its new name. Experienced SQL users usually drop the AS and specify immediately the alias name. Alias name is enclosed with quotation marks when used. Working with dates may be simplified if you use specific functions. The given example uses the YEAR () function that derives the year of specific date. YEAR () function is not limited with WHERE condition but works perfectly when used in performing computation with other dates. The given example shows the 10% increase on salary as you compute it. Combine this with an alias name in order to present your data in a clear manner. Most of thethese functions and clauses perfectly work with MySQL, Oracle, Informix, MS SQL Server other than DB2. Link for the ebook will be announced later.

Learn Python: Intro to SQL Queries
 
03:20
Learn all about SQL Queries in Python: https://www.datacamp.com/courses/introduction-to-relational-databases-in-python Introduction to SQL The SQL query language can be used to do anything within the database. It can select data, insert new data, update existing data, and delete it. It can also be used to create, alter and delete tables and columns. The first SQL statement we'll learn is the select statement, which provides the basic method of extracting information from your database. The general syntax of a select statement is select COLUMNS from TABLE CONDITIONS. For Example, we can select the pop2008 column from the people table. We can also select all the columns from the people table with a '*'. Let's execute this last query. We'll begin by importing create_engine and creating an engine. Next, we will establish a connection by using the connect method on the engine. Then we can define our select statement and pass it to the execute method on the connection. This gives us an object we can use to fetch the results, which we assign to the variable results_proxy. Then we tell results_proxy to fetch all the results via the fetchall method. Now results will contain all of our data from the people table. Let's pause for just a moment and look at that object that the execute method gave us. That object is called a ResultProxy and it can be used in a variety of different ways to get the data returned by our query. When we use a fetch method, such as fetchall, on the ResultProxy, we get a ResultSet that contains the actual data we asked for in the query. This separation between the ResultProxy and the ResultSet allows us to fetch as much or as little data as we desire. We'll explore this more in a later section. Let's learn how to work with a ResultSet. In this example we are using the results from the prior query. We'll start by getting the first_row of the results using an index of 0. By printing the first row, we can see the data it contains. If we want to know what columns are in the row, we can find out by using the keys method. Finally, we print the value of the state column from the first row, by using the column name as an attribute on the row object. In the prior query example, we wrote a normal SQL statement as a string; however, manipulating a string to build more complex statements can be very overwhelming. The beauty of SQLAlchemy is that it allows us to assemble these complex statements in a Pythonic way. Pythonic refers to code that adheres to the idioms of Python's common guidelines and express its intent in a highly readable way. SQLAlchemy also hides the difference between database types so we can focus on the data we want to work with instead of the differences we might encounter in each database type. Let's rebuild the same query using SQLAlchemy. The first three steps of creating an engine and establishing a connection will be the same. After that, we will need to initialize our metadata and reflect the table as we did previously. Then in line 7, we build our select statement. Hang tight we'll talk more about this in a second. Finally, we execute the statement and fetch all the results. The SQLAlchemy select statement works the same as a SQL select statement, and in its most basic form takes a list of Column or Table objects. For example, stmt = select([census]) will select all the columns of all the rows in the census table. SQLAlchemy generates the same SQL statement we wrote by hand. We can see that by using the print() function on the statement which outputs SELECT * FROM census. Now it's your turn write several SQL queries, both as raw SQL and in the more Pythonic way using SQLAlchemy. We'll be continuing to use the US Census database. Let's practice.
