Remove part of string in table

Question

I have a table where one field named "version" contains the string "MyProgram nnnnnn". I now wish to replace these strings so that they are only "nnnnnn", thereby remove the prepending "MyProgram ".

Is this possible, and if so, how would I do this?

Answer 1

If the pattern is "MyProgram nnnnnn" maning string like VB 1.3, Mysql 5.6, PHP 5.4 etc then you can do the following

update tablename 
set col = substring_index(col,' ',-1)

Answer 2

Use Replace function,

SELECT VERSION,  
REPLACE(VERSION,'MyProgram nnnnnn','nnnnnn')   
FROM FROM tablename 

Answer 3

您可以对MySQL使用Replace（）函数

update table set columnname = REPLACE(columnname, 'MyProgram ', '');

Answer 4

Check this Manual

SELECT REPLACE(VERSION, 'MyProgram ', '')
FROM tablename
