INSERT() :
This function in MySQL is used for inserting a string within a string, removing a number of characters from the original string.
Syntax :
INSERT(str, pos, len, newstr)
Parameters :
This method accepts four parameter.
- str – Original string in which we want to insert another string.
- pos – The position where we want to insert another string.
- len – The number of characters to replace.
- newstr – The string to be inserted.
Returns :
It returns a newly formed string.
Example-1 :
Inserting the string “mysql” into the string “geeksforgeeks” and replacing five characters, starting from position 9 with the help of INSERT Function.
SELECT INSERT("geeksforgeeks", 9, 5, "MySQL")
AS NewString ;Output :
| NEWSTRING |
|---|
| geeksformysql |
Example-2 :
The following MySQL statement returns Original string, the actual string itself. This happens because the position of insertion, which is specified as -5, is out of range, so no insertion takes place.
SELECT INSERT("geeksforgeeks", -5, 5, "MySQL")
AS NewString ;Output :
| NEWSTRING |
|---|
| geeksforgeeks |
Example-3 :
The following MySQL statement returns a completely new string. This happens because the position of insertion is 1 and length is number of character in previous string.
SELECT INSERT("geeksforgeeks", 1, 13, "stackoverflow")
AS NewString ;Output :
| NEWSTRING |
