Question

Hello I am trying to test the following mySql query within phpmyadmin before using it within a test enviorment page.

my result should update the donate_Total by adding a value of 2000 to the exsisting value held and storing the total in there where the first_Name and last_Name are matched. I have the user named in the sql code below but this won’t run, any pointers?

UPDATE `donate` SET `donate_Total`=  'donate_Total' + 2000 WHERE first_Name = 'Test'     AND last_Name ='One' ;

table name is donate and column name to update is donate_Total

Answer 1

change ‘donate_total’ to donate_total without the quotes. You are trying to add two intergers together, therefore you cannot put it as a string.

 UPDATE `donate` SET `donate_Total`=  donate_Total + 2000 WHERE first_Name = 'Test'     AND last_Name ='One' ;
