Difference Between TRIM() and TRIM_ORACLE() in MariaDB
MariaDB has a TRIM() function and a TRIM_ORACLE() function. Both functions do essentially the same thing. But there is a minor difference.
How TO_CHAR() Works in MariaDB
In MariaDB, TO_CHAR() is a built-in string function that converts a date/time expression to a string.
The expression can be a date, datetime, time, or timestamp value.
This function was introduced in MariaDB 10.6.1 to enhance Oracle compatibility.

SQL Server provides the STUFF() function that enables you to insert a string inside another string.
The function also allows you to specify the number of characters (if any) to delete from the original string in order to fit the new string.
Continue readingHow REGEXP_REPLACE() Works in MariaDB
In MariaDB, the REGEXP_REPLACE() function replaces occurrences of the substring within a string that matches the given regular expression pattern.
The whole string is returned along with the replacements.
If there’s no match (i.e. the input string doesn’t contain the substring), the the whole string is returned unchanged.
Continue readingHow REGEXP_SUBSTR() Works in MariaDB
In MariaDB, the REGEXP_SUBSTR() function returns the substring that matches the given regular expression pattern.
If there’s no match (i.e. the input string doesn’t contain the substring), the result is an empty string.
Continue readingHow REGEXP_INSTR() Works in MariaDB
In MariaDB, the REGEXP_INSTR() function returns the starting index of a substring that matches the regular expression pattern.
The index starts at 1. If there’s no match, the result is 0.
How NOT RLIKE Works in MariaDB
In MariaDB, NOT RLIKE is a negation of the RLIKE operator.
In other words, any time the RLIKE operator would return 1, NOT RLIKE will return 0.
How RLIKE Works in MariaDB
In MariaDB, the RLIKE operator is used to determine whether or not a string matches a regular expression. It’s a synonym for REGEXP.
If the string matches the regular expression provided, the result is 1, otherwise it’s 0.
