SQL Reference

SPACE(N)

n: The number of spaces to be returned by the “SPACE(N)” function. It is a required parameter where N represents an integer value indicating the count of spaces. The function then returns a string that consists of N number of spaces. It is important to know that N must be a positive integer, otherwise, the function will return an error.

Example

SELECT CONCAT('Hello', SPACE(5), 'World') AS SpacedString;

Output

+-----------------+
| SpacedString    |
+-----------------+
| Hello     World |
+-----------------+

Explanation

The example showcases the usage of the SPACE() function in MySQL. This function takes an integer as an argument and generates a string of spaces equal to the integer value. In this case, SPACE(5) generates a string of 5 spaces. CONCAT() function is used to join ‘Hello’, 5 spaces, and ‘World’ into a single string. As a result, it returns a string with ‘Hello’ and ‘World’ separated by 5 spaces.

SPACE( integer_expression )

integer_expression: This parameter determines the number of spaces to be returned by the SQL Server SPACE function. It should be an integer. If a negative number or a value larger than 255 is specified, NULL is returned.

Example

SELECT SPACE(5) + 'SQL';

Output

SQL

Explanation

In the given code example, the SPACE function in SQL is used to insert five spaces before the string ‘SQL’. The result is thus the string ‘SQL’ preceded by five spaces.

SPACE(n)

n: Integer value that specifies the number of spaces to be returned. The SPACE function will output a string consisting of ‘n’ number of space characters.

Example

SELECT SPACE(10) || 'Hello' FROM dual;

Output

          Hello

Explanation

The SPACE function in Oracle SQL creates a string of specified length filled with spaces. In this example, SPACE(10) creates a 10-character string filled with spaces. It’s followed by the string ‘Hello’, resulting in ‘Hello’ preceded by 10 spaces.

SPACE(n)

n: This parameter specifies the number of space characters to be returned by the function. Its value can be any positive integer.

Example

SELECT LENGTH(SPACE(5)) as Space_length;

Output

Space_length
------------
5

Explanation

The SPACE function in SQL is used to generate a string of spaces. In this example, SPACE(5) returns a string with 5 spaces. The LENGTH function then calculates the number of characters in this string, which is 5. This means that 5 spaces were created.
