MySQL TRIM Function: Remove Spaces

The TRIM() function in MySQL is used to remove unwanted characters (usually whitespace) from a string. This can be from the beginning (leading), the end (trailing), or both ends of the string (both).

Here is the syntax for the TRIM() function:

TRIM([{BOTH | LEADING | TRAILING} [remove_string] FROM] string)

Where:

BOTH, LEADING, TRAILING: This specifies where to trim characters from. If you omit this, BOTH is used by default.
remove_string: This is the string of characters that should be removed. If you omit this, spaces are removed by default.
string: This is the string from which the remove_string should be removed.

Examples:

Using TRIM with default parameters:

SELECT TRIM('   Hello World   ');

This will output 'Hello World', as the leading and trailing spaces are removed.

Using TRIM with LEADING:

SELECT TRIM(LEADING ' ' FROM '   Hello World   ');

This will output 'Hello World ', as only the leading spaces are removed.

Using TRIM with TRAILING:

SELECT TRIM(TRAILING ' ' FROM '   Hello World   ');

This will output ' Hello World', as only the trailing spaces are removed.

Using TRIM with a specific string to remove:

SELECT TRIM(BOTH 'H' FROM 'Hello WorldH');

This will output 'ello World', as the leading and trailing 'H' characters are removed.

Remember, the TRIM() function is case-sensitive. For example, TRIM('h' FROM 'hello') will return 'ello', but TRIM('H' FROM 'hello') will return 'hello', because 'H' does not exist in 'hello'.
