What is the default sort ORDER BY clause?

By default, SQL Server sorts out results using ORDER BY clause in ascending order. Specifying ASC in order by clause is optional.

What does sorted order mean?

Sorting is any process of arranging items systematically, and has two common, yet distinct meanings: ordering: arranging items in a sequence ordered by some criterion; categorizing: grouping items with similar properties.

What is the default sort order for a SQL query?

ascending order
The ORDER BY keyword sorts the records in ascending order by default. To sort the records in descending order, use the DESC keyword.

What is the default behavior when sorting a query?

ASC sorts the result set in ascending order by expression. This is the default behavior, if no modifier is provider. Optional.

What is the default order of ORDER BY clause Mcq?

The ORDER BY keyword sorts the records in ascending order by default.

What does SQL stand for?

Structured Query Language
SQL/Full name
SQL (pronounced “ess-que-el”) stands for Structured Query Language. SQL is used to communicate with a database. According to ANSI (American National Standards Institute), it is the standard language for relational database management systems.

Does SQL query automatically remove duplicates?

Explanation: An SQL does not remove duplicates like relational algebra projection, we have to remove it using distinct. … An SQL does not permit 2 attributes of same name in a relation.

How do I get alphabetical order in SQL?

If you want to sort based on two columns, separate them by commas. For example, ORDER BY LAST_NAME ASC, FIRST_NAME DESC; would display results sorted alphabetically by last name. If the same LAST_NAME matches multiple FIRST_NAME entries, the results of FIRST_NAME will also display in descending order.

What does NoSQL stand for?

not only SQL
When people use the term “NoSQL database,” they typically use it to refer to any non-relational database. Some say the term “NoSQL” stands for “non SQL” while others say it stands for “not only SQL.” Either way, most agree that NoSQL databases are databases that store data in a format other than relational tables.

What is SQL and HTML?

You can produce HTML from SQL because SQL Server has built-in support for outputting XML, and HTML is best understood as a slightly odd dialect of XML that imparts meaning to predefined tags. There are plenty of edge cases where an HTML structure is the most obvious way of communicating tables, lists and directories.

What is DDL in SQL?

In the context of SQL, data definition or data description language (DDL) is a syntax for creating and modifying database objects such as tables, indices, and users.

What is RDBMS?

The software used to store, manage, query, and retrieve data stored in a relational database is called a relational database management system (RDBMS). The RDBMS provides an interface between users and applications and the database, as well as administrative functions for managing data storage, access, and performance.

What does MySQL stand for?

Structured Query Language
MySQL (/ˌmaɪˌɛsˌkjuːˈɛl/) is an open-source relational database management system (RDBMS). Its name is a combination of “My”, the name of co-founder Michael Widenius’s daughter, and “SQL”, the abbreviation for Structured Query Language.

Is SQL deceased?

No, SQL isn’t dying. There are many very capable NoSQL stores that do their jobs very well, supporting massive scale out with low costs. … One day, SQL might be a thing of the past. A new system might be designed that completely replaces the traditional RDBMS.

What is Normalisation?

What Does Normalization Mean? Normalization is the process of reorganizing data in a database so that it meets two basic requirements: There is no redundancy of data, all data is stored in only one place. Data dependencies are logical,all related data items are stored together.

Is ms access a Rdbms?

MS Access is a Relational Database Management System so therefore RDBMS , however you can use it in a non-relational fashion if you so wish so it can be used as a DBMS .

What is the full form of DBMS?

A database management system (DBMS) that incorporates the relational-data model, normally including a Structured Query Language (SQL) application programming interface.

What is 1NF 2NF 3NF?

Types of Normal Forms

A relation is in 1NF if it contains an atomic value. 2NF. A relation will be in 2NF if it is in 1NF and all non-key attributes are fully functional dependent on the primary key. 3NF. A relation will be in 3NF if it is in 2NF and no transition dependency exists.

What is the difference between Normalising and annealing?

The main difference between annealing and normalizing is that annealing allows the material to cool at a controlled rate in a furnace. Normalizing allows the material to cool by placing it in a room temperature environment and exposing it to the air in that environment.

What is 1NF 2NF 3NF and BCNF?

1NF (First Normal Form) 2NF (Second Normal Form) 3NF (Third Normal Form) BCNF (Boyce-Codd Normal Form)

What is SQL 1NF?

First normal form (1NF) is a property of a relation in a relational database. A relation is in first normal form if and only if no attribute domain has relations as elements. … SQL does not support creating or using table-valued columns, which means most relational databases will be in first normal form by necessity.

How do you do second normal form?

A relation is in the second normal form if it fulfills the following two requirements: It is in first normal form. It does not have any non-prime attribute that is functionally dependent on any proper subset of any candidate key of the relation.

2NF and candidate keys.

Do you think Bcnf is better than 2NF & 3NF Why?

This relation is in 3NF as it is already in 2NF and has no transitive dependency. Also there is no non prime attribute that is deriving a non prime attribute.

Difference between 3NF and BCNF :
2.It is less stronger than BCNF.It is comparatively more stronger than 3NF.

Can one trigger initiate another trigger?

Both DML and DDL triggers are nested when a trigger performs an action that initiates another trigger. These actions can initiate other triggers, and so on. DML and DDL triggers can be nested up to 32 levels. You can control whether AFTER triggers can be nested through the nested triggers server configuration option.

How do you normalize?

First normal form (1NF) sets the fundamental rules for an organized database:
  1. Eliminate duplicative columns from the same table.
  2. Create separate tables for each group of related data and identify each row with a unique column or set of columns (the primary key).
