![]() Consider the following statement to do the same. Consider the following example, which removes more than one space that occurred in a string. Remove multiple occurrences of the spaces. ']'Īlso, we have used the replacement string as ‘’ and the flag ‘g’ we have used to instruct the PostgreSQL REGEXP_REPLACE function to replace all of the occurrences of the matched string and not just the first occurrence. In the above examples, we have used the following regular expressions. Now, we will remove all digits from the above string by using the following statement: SELECT REGEXP_REPLACE('xyz54321ABC', Now, we will remove all alphabets characters from the above string by using the following statement: SELECT REGEXP_REPLACE('xyz54321ABC', Illustrate the result of the above statement by using the following snapshot.Įxample, to remove the string, consider we have a string in the following as follows: "xyz54321ABC" So, we can use the PostgreSQL REGEXP_REPLACE() function to do this as follows: SELECT REGEXP_REPLACE('Jacob David', Suppose we want to re-arrange the last name and the first name for purposes like the last name and then the first name. Here are the following examples of implementing the PostgreSQL REGEXP_REPLACE function Example #1 – Example to arrange the nameĬonsider the following name format like the first name and then last name: Replace_string: This string defines a string that replaces the substring, which matches the POSIX regular expression pattern.flags: This flag is used to control the behavior of the REGEXP_REPLACE() function, This can have the value of one or more characters. ![]() regex_pattern: This defines the POSIX regular expression to match the string.input_string: This defines the input string in which replacement should be taken place for a specified pattern, a POSIX regular expression.REGEXP_REPLACE(input_string, regex_pattern, replace_string,)
