http://www.sqltrainingonline.com SQL Null or Empty - How to Check for Null or Empty Column in SQL Server - SQL Training Online You can download the sample table script at http://www.sqltrainingonline.com/how-to-filter-for-sql-null-or-empty-string/. In this video, I show you how to filter for a SQL null or empty string. It can be difficult to filter a null because you can't simply compare with an equal sign. You have to use a special IS NULL clause to make the filter work. I also show you how to combine both the SQL Null and Empty String together in a special trick with the isnull SQL Server function. I use SQL Server 2012 to demonstrate the technique.

IS NULL Operator in SQL Query with Example
 
02:24
SQL IS NULL Operator: A column value is NULL if it does not exist. The IS NULL operator is used to display all the rows for columns that do not have a value. For Example: If you want to find the emp names who do not get any commision, the query would be as given below: select * from emp where COMM IS NULL; In the opposite way, NOT NULL also works here: select * from emp where COMM IS NOT NULL; Thanks for watching..:)

Oracle LENGTH Function
 
01:23
https://www.databasestar.com/oracle-length/ The Oracle LENGTH function allows you to find the length of a string, also known as the number of characters in a string. It’s a common feature in different languages, and SQL is no different. The LENGTH function only has one parameter: LENGTH ( string_value ) The parameter is the string_value which is the value to check the length of. The function returns a number that represents the number of characters in the function. Some points to remember about the Oracle LENGTH function: If string_value is NULL, then LENGTH will return NULL. If string_value is an empty string, the LENGTH will return NULL. The string_value can be any of the character data types - CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, NCLOB. If the string_value is a CHAR data type, then the LENGTH will include any trailing spaces in the value. For more information about the Oracle LENGTH function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-length/

Please watch: "Be Technical..!! Please Subscribe to my Channel...!!!! " https://www.youtube.com/watch?v=ISg0o8A575E --~-- After watching this video you will be able to know that how can we replace null value with any other value. There are three different ways to replace null with any other statement. 1 is ISNULL() function in which we just have to specify the two parameters one parameter is for expression and and the second is for the value you want to input instead of null. 2nd method is COALESCE() function in this function you can put more then one expressions and replacement values. and like the ISNULL() function you will see that the null value will be replaced with the value you provide for replacement. 3rd and the last one is CASE. in Case statement there is condition like " case when Expression is null then replacement value else the column name or the expression.

SQL Tutorial 7: CONCAT function, ORDER BY, NULL value
 
09:21
How do you concatenate or combine columns and place it on a derived column? How do you check if a column contains NULL value? How do your arrange rows or records in descending or ascending order? The video presents sample problems with solution as you work with a SELECT statement. CONCAT () function combines data among columns. It is not limited with two columns but may work with multiple columns as you combine it with another CONCAT function. Use two double-pipe symbols (||) instead if you opt not to use CONCAT function. Not all columns are filled up or has values on it in a given table. When a column contains no data even a single space, it has a NULL value. In using DB2 command line, a NULL column is represented by a single dash. When generating a SELECT statement output it has no general sorting order on its result. To specify the correct sorting order, use ORDER BY clause after FROM. Ascending is the default order when sorting a particular column. If you want to sort in descending order, use DESC. Sort order is not limited with one column. You may combine with multiple columns by specifying which column to sort first followed by the next column order to sort. CONCAT, ORDER BY, and NULL are universal in all dbms SQL products. It is the same if you use MS SQL Server, MySQl, Informix, Oracle, and DB2. Link for the ebook will be announced later.

Dynamic SQL in Stored Procedure
 
09:32
In this video we will discuss, using dynamic sql in a stored procedure and it's implications from sql injection perspective. We will discuss performance implications of using dynamic sql in a stored procedure in a later video. Text version of the video http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html Slides http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure_11.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All SQL Server Tutorial Videos https://www.youtube.com/playlist?list=PL08903FB7ACA1C2FB All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists Consider the following stored procedure "spSearchEmployees". We implemented this procedure in Part 139 of SQL Server tutorial. This stored procedure does not have any dynamic sql in it. It is all static sql and is immune to sql injection. Create Procedure spSearchEmployees @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Select * from Employees where (FirstName = @FirstName OR @FirstName IS NULL) AND (LastName = @LastName OR @LastName IS NULL) AND (Gender = @Gender OR @Gender IS NULL) AND (Salary = @Salary OR @Salary IS NULL) End Go Whether you are creating your dynamic sql queries in a client application like ASP.NET web application or in a stored procedure, you should never ever concatenate user input values. Instead you should be using parameters. Notice in the following example, we are creating dynamic sql queries by concatenating parameter values, instead of using parameterized queries. This stored procedure is prone to SQL injection. Let's prove this by creating a "Search Page" that calls this procedure. Create Procedure spSearchEmployeesBadDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and FirstName=''' + @FirstName + '''' if(@LastName is not null) Set @sql = @sql + ' and LastName=''' + @LastName + '''' if(@Gender is not null) Set @sql = @sql + ' and Gender=''' + @Gender + '''' if(@Salary is not null) Set @sql = @sql + ' and Salary=''' + @Salary + '''' Execute sp_executesql @sql End Go Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicSQLInStoredProcedure.aspx". Copy and paste the HTML and code available on my blog at the following link http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html At this point, run the application and type the following text in the "Firsname" text and click "Search" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. ' Drop database SalesDB -- In the following stored procedure we have implemented dynamic sql by using parameters, so this is not prone to sql injecttion. This is an example for good dynamic sql implementation. Create Procedure spSearchEmployeesGoodDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Declare @sqlParams nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and [email protected]' if(@LastName is not null) Set @sql = @sql + ' and [email protected]' if(@Gender is not null) Set @sql = @sql + ' and [email protected]' if(@Salary is not null) Set @sql = @sql + ' and [email protected]' Execute sp_executesql @sql, N'@FN nvarchar(50), @LN nvarchar(50), @Gen nvarchar(50), @sal int', @[email protected], @[email protected], @[email protected], @[email protected] End Go On the code-behind page, use stored procedure spSearchEmployeesGoodDynamicSQL instead of spSearchEmployeesBadDynamicSQL. We do not have to change any other code. At this point run the application one more time and type the following text in the "Firstname" textbox and click the "Search" button. ' Drop database SalesDB -- Notice "SalesDB" database is not dropped, So in this case our application is not succeptible to SQL injection attack. Summary : Whether you are creating dynamic sql in a client application (like a web application) or in a stored procedure always use parameters instead of concatnating strings. Using parameters to create dynamic sql statements prevents sql injection.

Oracle SQL Tutorial 10 - Whitespace, Case Sensitivity, and Comments
 
07:48
SELECT "Hello World" FROM DUAL The first thing you should know about writing queries is that this SQL is not whitespace sensitive. That means we can space this out however we wish. The only requirement is that you do not separate keywords out with spaces. They must be as one entity. Another gotcha is that when you are inside of quotes, whitespace becomes very important. That means if inside of a string you put a character and then 10 spaces, every single one of those spaces is going to part of that string: SELECT "Hello World" FROM DUAL The next thing you should notice is the capitalization. When we type SQL, by convention we capitalize all keywords. I personally really like this because you can easily see the difference between keywords and words that we created or use. But obviously we could capitalize the letters in the quotes. Keep in mind that this is a convention, meaning you do not have to follow this. Oracle is also case insensitive in that SELECT and select both do the same thing. Strings, once again, care about casing. Take this, for example: SELECT 'true' FROM DUALWHERE 'Hello' = 'Hello' And compare the results to this: SELECT 'true' FROM DUALWHERE 'Hello' = 'hello' Only the first one outputs the value true. Once we get into creating database objects such as tables with columns, those are not case sensitive either. That means instead of selecting from DUAL, you can select from DuAl Finally, I shall introduce you to comments. Comments allow you to tell the database engine that you want it to ignore a certain part of your code and not execute it. This is helpful if you want to document your code. It is also useful if you want to have multiple SQL statements open in one tab, but don't want to hover over the one you want to execute. You can comment out the ones you are not using and uncomment them when you are done. Using – will comment out the rest of the line, Using /* */ will comment everything between. This can even be used over multiple lines.

We have already discussed the intro of SQL character function in Video 10. You can find link of this video in description below. Ok let's go ahead. SQL Concat () function concatenates two separate character string into one character string. Let's see the syntax Concat (string_1 , String_2) Note here that SQL Concat function takes only two arguments at a time. This SQL Concat function will return string_1 concatenated with string_2. This also means that it will return a single string which is a combined string of parameter String_1 and String_2. Both the parameters of SQL Concat function String_1 and string_2 can be of any data-type. You can even specify the columns of the table here. SQL Concat function is equivalent to the concatenation operator (||). SQL concatenation operator is represented by double solid vertical bars or we can say double pipe signs. Question: How to concatenate more than two strings as SQL Concat that can have only 2 parameters and what is the difference between SQL Concat Function and SQL concatenation operator? The one answer for the second Question What is the Difference between SQL Concat Function and SQL concatenation operator? Is While SQL Concat function takes only two parameters, The Concat operator can be repeated as often as is necessary. Meaning, by the help of SQL Concat operator you can combine as many strings as you want. And Concatenation operator is also not supported by several databases such as SQL server so this might cause problem. To answer the first question How to concatenate more than two strings as SQL Concat that can have only 2 parameters? We will have to jump over SQL developer. Let's see some examples. Say we want to retrieve the full name of an employee from Employees table. Let's try it using SQL Concat function. SELECT Concat (first_name, last_name) AS "Full Name" FROM employees; Here in this query we use two column names - first_name and last_name as arguments of our Concat function Execute. As you can see here, we get full name of our employee but there is no space in between first name and last name. We will see how to format this string using SQL Concat function in a few seconds But before that, let's see how to do the same task using SQL concatenation operator. SELECT first_name ||last_name AS "Full name" FROM employees; As you can see this query also produces the same result. Now we will see how to format full name of employees First we will do this using SQL concatenation Operator. SELECT first_name||' '||last_name AS "Full name" FROM employees; Now you can see we get space between first name and last name of the employee. Again, let's do it using SQL Concat function. Here we will see the nested function concept where we will be using nested Concat function to achieve this formatted string. SELECT Concat (Concat (first_name, ' '), last_name) FROM employees; Inner Concat function has two parameters. These are our first column name first_name and an empty string which will be a space between first name and second name. This Concat will now return a string which is the first name with space. This returning string will be the first input of our Outer Concat and column last_name will be the second input. All together this will give us the desired output. As you can see this method is complex than the first one where we use SQL concatenation operator.
