In SQL, SMALLINT is a numeric data type that stores integer values ranging from -32,768 to 32,767. The SQL SMALLINT data type takes up 2 bytes of storage space and is commonly used for columns that store small numbers. The main advantage of using the SMALLINT data type is that it requires less storage space…(Continue Reading)

In SQL, the INTEGER data type is used to represent a whole number value that does not have any fractional part. It is a commonly used data type for storing numerical data in databases, particularly when dealing with data that involves counting or measuring. Syntax INTEGER | INT The INTEGER data type can be specified…(Continue Reading)

One of the key features of SQL language is its support for different data types, which allows developers to store and work with different kinds of data in a database. When creating tables or declaring variables in SQL, it’s important to specify the data type for each column or variable. The data type determines the…(Continue Reading)

The SQL EXP() function is a mathematical function that calculates the exponential value of a given number. It is commonly used in SQL queries to calculate exponential values of numbers stored in a database table. Syntax The syntax of the SQL EXP() function is: EXP(number) Where number is the input value for which the exponential…(Continue Reading)

The SQL LOG function is used to calculate the natural logarithm of a given numeric expression. The natural logarithm of a number is the logarithm to the base e, where e is a mathematical constant that is approximately equal to 2.71828. Syntax The syntax of the LOG function in SQL is as follows: LOG(numeric_expression) Here,…(Continue Reading)

The SQL SIGN function is a mathematical function that is used to determine the sign of a numeric expression. The function returns a value of -1, 0, or 1, depending on whether the input expression is negative, zero, or positive, respectively. Syntax The syntax of the SIGN function is as follows: SIGN(numeric_expression) Here, numeric_expression is…(Continue Reading)

The SQL POWER function is a built-in mathematical function in SQL that returns the value of a number raised to a specified power. The function takes two arguments: the base number and the exponent, and returns the result of the base number raised to the exponent. Syntax The syntax for using the POWER function in…(Continue Reading)

SQL Math functions are a set of built-in functions that allow performing mathematical calculations and operations on numerical data stored in a database. These functions provide a convenient way to manipulate and transform data within a database, without the need for external tools or programming languages. Benefits of SQL Math Functions Efficiency: SQL Math functions…(Continue Reading)

The SQL SQRT function is a built-in mathematical function in SQL that returns the square root of a given numeric value. It is used to calculate the square root of a numeric value in a SQL statement. Syntax The syntax for the SQRT function in SQL is as follows: SQRT(value) Here, the value parameter is…(Continue Reading)

The SQL FLOOR function is used to return the largest integer that is less than or equal to a given numeric expression. In other words, it rounds down the input value to the nearest integer value. The syntax of the FLOOR function is as follows: FLOOR(numeric_expression) where numeric_expression is the value that needs to be…(Continue Reading)
