mySQL UPDATE query returns "0 rows affected" -


I have this query: 

  Call phone calls Set "yes" Where is the phone number = "999 29-4655"

my table is phone call ; I have a column whose name is phone number . The one I want to update is a column that has been named "yes" from called .

Any thoughts that I am doing wrong? When I return my query, it says that 0 rows have been affected.

Amphitamin and Yada have suggested, code> select , if your phone number table Is in.

But keep in mind: If the line in the called is already "yes", Mysql will not change the value and therefore will return "affected 0 rows". So make sure to check the current value of called

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
