In MariaDB, you can use SOUNDS LIKE in a query to match words that sound alike.
string functions
How SOUNDEX() Works in MariaDB
In MariaDB, SOUNDEX() is a built-in string function that returns the Soundex string from a given string.
Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. If two words sound the same, they should have the same Soundex string. If two words sound similar, but not exactly the same, their Soundex string might look similar but not exactly the same.
The function accepts one argument: the string for which to return the Soundex string from.
How REVERSE() Works in MariaDB
In MariaDB, REVERSE() is a built-in string function that returns a string with the characters in reverse order.
The function accepts one argument: the string to reverse.
How REPLACE() Works in MariaDB
In MariaDB, REPLACE() is a built-in string function that allows you to replace a part of a string with another string.
The function accepts three arguments: the string, the substring to replace, and the string to replace the substring with.
How POSITION() Works in MariaDB
In MariaDB, POSITION() is a built-in string function that returns the position of the first occurrence of a substring within another string. It’s part of ODBC 3.0.
POSITION(substr IN str) is a synonym for LOCATE(substr,str).
POSITION() is also similar to the INSTR() function, except that POSITION() uses the IN syntax, and that the argument order is reversed between these two functions.
How SUBSTRING_INDEX() Works in MariaDB
In MariaDB, SUBSTRING_INDEX() is a built-in string function. It returns a substring from a string before a certain number of occurrences of the specified delimiter.
SUBSTRING_INDEX() requires at three arguments; the string, the delimiter, and the count (i.e. number of occurrences of that delimiter).
How REPEAT() Works in MariaDB
In MariaDB, REPEAT() is a built-in string function that returns a string repeated a certain number of times.
You pass the string, as well as the number of times you want it repeated when you call the function.
How QUOTE() Works in MariaDB
In MariaDB, QUOTE() is a built-in string function that allows you to escape a string so that it’s suitable for inclusion in an SQL statement.
The string is returned enclosed by single quotes, and a backslash is prepended to each instance of single quote ('), backslash (\), ASCII NUL, and Control-Z characters.
How MID() Works in MariaDB
In MariaDB, MID() is a synonym for SUBSTRING(). It returns a substring from a given string.
According to the MariaDB documentation it’s a synonym for the SUBSTRING(str,pos,len) syntax of SUBSTRING(), however, my tests show that it works with all of the various forms.
MariaDB SUBSTR() Explained
In MariaDB, SUBSTR() is a synonym for SUBSTRING().
It’s a built-in string function that returns a substring from a given string.
It requires at least two arguments; the string, and the position for which to extract the substring from. It also accepts an optional third argument that allows you to specify how long the substring should be.
