How to delete a record in a table using SQL?

The SQL DELETE Query is used to delete the existing records from a table.

You can use WHERE clause with DELETE query to delete selected rows, otherwise all the records would be deleted.

Syntax:
The basic syntax of DELETE query with WHERE clause is as follows:

DELETE FROM table_name
WHERE [condition];

Example:
Consider the CUSTOMERS table having the following records:
+—-+———-+—–+———–+———-+
| ID | NAME | AGE | ADDRESS | SALARY |
+—-+———-+—–+———–+———-+
| 1 | Ramesh | 32 | Ahmedabad | 2000.00 |
| 2 | Khilan | 25 | Delhi | 1500.00 |
| 3 | kaushik | 23 | Kota | 2000.00 |
| 4 | Chaitali | 25 | Mumbai | 6500.00 |
| 5 | Hardik | 27 | Bhopal | 8500.00 |
| 6 | Komal | 22 | MP | 4500.00 |
| 7 | Muffy | 24 | Indore | 10000.00 |

Following is an example, which would DELETE a customer, whose ID is 6:

DELETE FROM CUSTOMERS
WHERE ID = 6;

If you want to DELETE all the records from CUSTOMERS table, you do not need to use WHERE clause and DELETE query would be as follows:

DELETE FROM CUSTOMERS;

SQL Server next version CTP 1.4

Microsoft is excited to announce a new preview for the next version of SQL Server (SQL Server v.Next). Community Technology Preview (CTP) 1.4 is available on both Windows and Linux. In this preview, they added the ability to schedule jobs using SQL Server Agent on Linux. We can try the preview in your choice of development and test environments now: www.sqlserveronlinux.com.

Key CTP 1.4 enhancements
The primary enhancement to SQL Server v.Next on Linux in this release is the ability to schedule jobs using SQL Server Agent. This functionality helps administrators automate maintenance jobs and other tasks, or run them in response to an event. Some SQL Server Agent functionality is not yet enabled for SQL Server on Linux. To learn more and see sample SQL Server Agent jobs, you can read detailed blog titled “SQL Server on Linux: Running scheduled jobs with SQL Server Agent” or attend an Engineering Town Hall about “SQL Server Agent and Full Text Search in SQL Server on Linux.”

The mssql-server-linux container image on Docker Hub now includes the sqlcmd and bcp command line utilities to make it easier to create and attach databases and automate other actions when working with containers. For additional detail on CTP 1.4, please visit What’s New in SQL Server v.Next, Release Notes and Linux
documentation.

In addition, SQL Server Analysis Services and SQL Server Reporting Services developer tools now support Visual Studio 2017. They are available for installation from the Visual Studio Marketplace providing the option for automatic updates going forward.

Difference Between SQL & SQL Server

SQL Server is an RDBMS just like oracle,DB2 from Microsoft

Structured Query Language (SQL), pronounced “sequel”, is a language that provides an interface to relational database systems. It is an open, vendor-independentIt was developed by IBM in the 1970s for use in System R. SQL is a de facto standard, as well as an ISO and ANSI standard. SQL is used to perform various operations on RDBMS

SQL is the basic ANSI standard for accessing data in a relational database. When you see “MSSQL” it is referring to Microsoft SQL Server, which is the entire database architecture and not a language. T-SQL is the proprietary form of SQL used by Microsoft SQL Server. It includes special functions like cast, convert, date(), etc. that are not part of the ANSI standard.

You will also see things like plSQL, which is Oracle’s version of SQL, and there are others as well (mySQL has its own version, for example, and Microsoft Access uses Jet SQL.)

It is important to note the the ANSI standard for SQL has different releases (for example, 92 or 99, representing the year it was released.). Different database engines will advertise themselves as “mostly ANSI-92” compliant or “fully ANSI-99” compliant, etc, and any exceptions will usually be documented.

So although “SQL is SQL”, every engine uses its own “flavor” of it, and you do have to do a little reading on the particular platform before you just dive in.

A further note – the SQL extensions, like T-SQL, are generally considered full-fledged programming languages, complete with looping, if/then, case statements, etc. SQL itself is limited to simply querying and updating data and is not considered a true programming language.
