In the second example the variable is NUMBER OF HOURS, the constant is 100, and the comparison operator is >. You need to know about two more elements SQL Server DBA online training videos before you can write conditional queries: the WHERE clause and operators. Operators are the elements you use inside an expression to articulate how you want specified conditions to retrieve data. Operators fall into six groups: arithmetic, comparison, character, logical, set, and miscellaneous. What is this last column with the unattractive column heading WHOLESALE+0.15? It’s not in the original table. SQL videos allow you to create a virtual or derived column by combining or modifying existing columns. To understand how you could get an Unknown, you need to know a little about the concept of NULL. In database terms, NULL is the absence of data in a field. It does not mean a column has a zero or a blank in it.

SQL Server DBA online training videos have tried to keep the language of the SQL server training videos as plain-English and matter-of-fact as possible because that is the way I teach. I have supplied you with substantial technical background, while also supplying numerous examples. This SQL learning online can be used as a tutorial or desktop reference to help you get Microsoft SQL Server to fulfill your organization’s needs.

SQL Server online training has been through many classes as a student and as an instructor about topics ranging from adult learning principles to Microsoft sql server Administration. From these classes, I have acquired a great deal of knowledge that can be applied to creating a solid production data server with Microsoft sql server training.

SQL Server DBA online training videos want to share that with you and help you head off the problems that you may encounter configuring your servers. Conditions enable you to make selective queries. In their most common form, conditions comprise a variable, a constant, and a comparison operator. In the first example, the variable is NAME, the constant is ‘BROWN’, and the comparison operator is=.

SQL Server DBA online training videos are really very beneficial as you can learn at your leisure time. You can pick and choose SQL online videos course out of this vast library of oracle sql training videos. Watch over the shoulder simply explains and demonstrates each important function, feature, and shortcut with SQL screenshots, demos, and practical theory. A zero or a blank is a value.

NULL means nothing is in that field. If you make a comparison like Field = 9 and the only value for Field is NULL, the comparison will come back Unknown. Because Unknown is an uncomfortable condition, most flavors of SQL change Unknown to FALSE and provides a special operator, IS NULL, to test for a NULL condition. Notice that nothing is printed out in the WHOLESALE field position for oranges.

The value for the field WHOLESALE for oranges is NULL. The NULL is noticeable in this case because it is in a numeric column. However, if the NULL appeared in the ITEM column, it would be impossible to tell the difference between NULL and a blank.

You didn’t find anything because the comparison WHOLESALE = NULL returned a FALSE–the result was unknown. It would be more appropriate to use an IS NULL instead of =, changing the WHERE statement to WHERE WHOLESALE IS NULL. In this case, you would get all the rows where a NULL existed. This example also illustrates both the use of the most common comparison operator, the equal sign (=), and the playground of all comparison operators, the WHERE clause.

You already know about the WHERE clause, so here’s a brief look at the equal sign. Earlier today you saw how some implementations of SQL use the equal sign in the SELECT clause to assign an alias. In the WHERE clause, the equal sign is the most commonly used comparison operator. do not need to have any previous experience (oracle training) with SQL Server DBA online training videos as it will take you through from Beginner or Basic and make you highly comfortable with inner workings of SQL online training to increase your proficiency.
