In this example, we have used the we used the (?-i) pattern to force the REGEXP_REPLACE function to perform case-sensitive pattern matching. This can be done using the (?-i) pattern. If we wanted to perform a case-sensitive search, we need to modify our REGEXP_REPLACE function to use a binary string. The REGEXP_REPLACE function performs a case-insensitive search so it doesn't matter whether "a", "e", "i" or "o" values are uppercase or lowercase. These REGEXP_REPLACE examples will replace all occurrences of the letters "a", "e", "i" or "o" in the string "TechOnTheNet" with "8".

Let's start by looking how to use the | pattern with the REGEXP_REPLACE function in MariaDB.įor example: SELECT REGEXP_REPLACE ('TechOnTheNet','a|e|i', '8') All occurrences of pattern found within string are replaced with replacement.Įxample - Match on more than one alternative Matches the preceding pattern at least n times, but not more than m times. Matches the preceding pattern at least n times. Matches the preceding pattern zero or one occurrence. Matches the preceding pattern one or more occurrences. Matches the preceding pattern zero or more occurrences. Matches one collation element that can be more than one character. Matches the nth subexpression found within ( ) before encountering \n. Matches at least m times, but no more than n times. Used to group expressions as a subexpression. Used to specify a nonmatching list where you are trying to match any character except for the ones in the list.
Used to specify a matching list where you are trying to match any one of the characters in the list. Used like an "OR" to specify more than one alternative. If used with a match_parameter of 'm', it matches the end of a line anywhere within expression. If used with a match_parameter of 'm', it matches the start of a line anywhere within expression. It can be a combination of the following: Value The regular expression matching information. The syntax for the REGEXP_REPLACE function in MariaDB is: REGEXP_REPLACE( string, pattern, replacement ) Parameters or Arguments string The string to search.
