The WITH clause in SQL allows us to provide a sub-query block, a name that can be referenced in several places within the main query. It is used for defining a temporary relation whose definition is available by the query in which the WITH clause is associated.

The correct answer is IN

The IN operator easily tests the expression if it matches any value in a specified list of values. It reduces the use of multiple OR conditions.

The WHERE or HAVING clause uses the ANY and ALL operators. ANY gives the result when any subquery value matches the specified condition. The ALL give the result when all subquery values match the specified condition.

The BETWEEN operator selects values only in the given range.

A view is also known as a virtual table because it contains rows and columns similar to a real table. It shows the table interface but cannot be stored in a database.

The correct answer is COMMIT and ROLLBACK

TCL stands for Transaction Control Commands used for managing the changes made by DML commands like INSERT, DELETE, and UPDATE. The TCL commands are automatically committed in the database; that’s why we cannot use them directly while creating tables or dropping them.

The correct answer is DECIMAL

DECIMAL is not a valid SQL type because it is nothing but numeric only in SQL.

NUMERIC has fixed precision, and scale numbers range from -10^38+1 to 10^38-1.

FLOAT has floating precision number ranges from -1.79E + 308 to 1.79E + 308.

CHARACTER is a fixed-width character string data type that can be up to 8000 characters.

The main MySQL program that does all the data handling is called mysqld

The correct answer is A Client Program That Lets You Send SQL Commands To The Database Engine

The REVOKE statement can be used to undo the action of a GRANT statement. It revokes a privilege from a grantee, but only if that exact privilege was granted to the same grantee before.

Create Database. Because MySQL is an open-sourced RDBMS or Relational Database Management System. So, in MySQL, you could create a Database

The correct answer is DROP TABLE XXX

The correct answer is the Structured Query Language

The correct answer is Some sort of client program to access the databases

The Relay Log has the data changes received from a replication master server written in it. The problems encountered during the starting, running, or stopping of ‘mysqld’ are written in the error log.

The function ‘fetchrow_hashref()’ returns a reference to a hash of row values, keyed by the column name.

The utility program ‘mysqldbcopy’ is capable of copying databases from one server to another server. It can also prepare copies to make transfers on the same servers.
