Question

My table structure in the database;

Table “System_t”

id         |    Owner     |    System
===========================================
1          |    Joe       |    Registration
           |              |    Event             //contains new line
           |              |    Aims
-------------------------------------------
2          |    Rose      |    Ticket
           |              |    Elearning

NOTE : The data field “System” were saved from a Textarea box.

My problem is how am I going to delete only the “Event” data from the field “System”?

My table should be look like this when it is deleted;

id         |    Owner     |    System
===========================================
1          |    Joe       |    Registration
           |              |    Aims
-------------------------------------------
2          |    Rose      |    Ticket
           |              |    Elearning 

Any idea how to do it without changing the table structure?

Answer 1

An UPDATE statement with a REPLACE should be better in this case.
