Bootstrap 4 Alert Box

Bootstrap 4 supports a variety of responsive alert messages using predefined contextual classes.
The list of contextual classes are,

Primary (.alert-primary)
Secondary (.alert-secondary)
Success (.alert-success)
Danger (.alert-danger)
Warning (.alert-warning)
Info (.alert-info)
Light (.alert-light) and
Dark (.alert-dark)

The Bootstrap 4 provides an optional dismiss button as well as it also supports the large length of text without breaking the flexibility.

To create an alert box, include the .alert class in your element followed by any of the contextual classes that are mentioned above.
Let's look into an example,

<div class="alert alert-info" role="alert">
  <strong><i class="fa fa-info-circle" aria-hidden="true"></i></strong> 
Use this alert box when you need to highlight the <b>info</b> message!
</div>

Alert Box (Links)

Include .alert-link class to any of your alert box to create best colored links.

Let's put this together into practice,

Alert Box (Dismissible)

The .alert-dismissible class is used to close the alert box with the help of an inline close button.

<div class="alert alert-primary alert-dismissible" role="alert">
  <strong><i class="fa fa-info-circle" aria-hidden="true"></i></strong> 
Use this alert box when you need to highlight the <b>primary</b> message!
    <button type="button" class="close" data-dismiss="alert" aria-label="Close">
    <span aria-hidden="true">&times;</span>
  </button>
</div>

FORCE ORDER in SQL Server

The FORCE ORDER is a query hint it executes the order of the tables exactly specified in a statement. When we use this query hint in a statement it will tell SQL server not to change the order of the joins in the query. Basically, the SQL server rearrange your joins to be in the order that it thinks it will be optimal for your query to execute. Now, Lets see the execution plan without the FORCE ORDER: The above execution plan demonstrates the optimal order of the joins returned by the SQL server. As you can see the order starts from the sales details and goes by bank details to employee details. Suppose if you don't want the SQL server to change the order of the joins in a query you can use FORCE ORDER to stop the default ordering. The syntax for FORCE ORDER query hint is, OPTION ( FORCE ORDER ); Now, Lets see the execution plan with the FORCE ORDER: select * from tbl_EmployeeDetails as e inner join tbl_BankDetails as b on e.Id=b.EmpID inner join tbl_S...

OPTION (MERGE JOIN) in SQL Server

OPTION (MERGE JOIN) in SQL Server The MERGE JOIN query hint is a best available join algorithm in SQL server. It is based on first sorting both data sets according to the join conditions and then traversing through the sorted data sets and finding matches. The MERGE JOIN itself is very fast, but it can be an expensive choice if sort operations are required. This produces the best optimal execution plan. The syntax is, OPTION ( MERGE JOIN ); Now, Lets see how to use MERGE JOIN with SELECT statement.? select * from tbl_EmployeeDetails as e inner join tbl_BankDetails as b on b.EmpId=e.Id OPTION(MERGE JOIN); The statement returned optimal execution plan is, The MERGE JOIN operator gets a row from each input and compares them. In above statement, it merges all joins and first sorting data sets and then traversing through the sorted data sets and finding matches, if they are equal the rows are returned. If they are not equal, the lower-value row is rem...

How to manipulate JSON data in SQL server?

OPTION Loop Join in SQL Server

The OPTION ( LOOP JOIN ) would enforce LOOP JOIN across all joins in the query. Using the OPTION ( LOOP JOIN ) appears to allows the query optimizer to join the tables using the nested loops in which ever order SQL server decides it is optimal. The OPTION clause must be a last clause in a statement. The syntax is, OPTION ( LOOP JOIN ); Now, Lets see how to use LOOP JOIN with SELECT statement.? select *from tbl_EmployeeDetails as e inner join tbl_BankDetails as b on b.EmpID=e.Id inner join tbl_SalesDetails as s on s.BankId=b.Id OPTION(LOOP JOIN); The statement returned execution plan is, The above statement loops through all the joins that starts from sales details and goes by bank details to employee details in which the order that SQL server thinks it is optimal. This does not follow the order of joins that we specify. Suppose, if you want the SQL server to follow the order of joins that you specify you have to use FORCE ORDER in OPTION clause. Howe...
