kamal213 Posted August 2, 2011 Share Posted August 2, 2011 Hi guys, I was wondering if there is a way or if its possible to check the database if the field has already been updated..just like you would if data has already been inserted into the field. Please let me know if you need more info Thanks Quote Link to comment Share on other sites More sharing options...
kickstart Posted August 2, 2011 Share Posted August 2, 2011 Hi Depends on the situation. If you were inserting a record that has some unique key field then you use ON DUPLICATE KEY UPDATE syntax to catch it and instead update the row. All the best Keith Quote Link to comment Share on other sites More sharing options...
Muddy_Funster Posted August 2, 2011 Share Posted August 2, 2011 You posted this exact same question in PHP support. Don't duplicate your posts (against the rulles) and if you hadn't wasted time typing the same thing twice you could have used it to post some relevent information regarding the scenrio that you are describing.

Muddy_Funster Posted August 2, 2011 Share Posted August 2, 2011 You've made over 60 posts so your not that new, also you agreed to the Rules when you created your account. I was giving you advice and so in a way trying to help you, but OK, some more direct help for you then: Forum Rules Failure to comply with any of the following rules is breach of contract and as such, administrators and moderators can take appropriate action as they see fit.

Do not use one of the public forums for this. And you still need to provide more information about what it is you are trying to do, to what, and what data is already there if any, for you to get the help that you are looking for.

trq Posted August 2, 2011 Share Posted August 2, 2011 Muddy_Funster, you might want to read the rule right under the one you highlighted. Quote Link to comment Share on other sites More sharing options...
kamal213 Posted August 2, 2011 Author Share Posted August 2, 2011 I havent been here long enough to know all the rules you have listed Muddy_Funster..you obviously have that why you do. I did what I did because I wanted the perspective of someone good with PHP and someone good with SQL..i simple copied n paste to save time obviously the mistake - Again I wasnt aware of the rules.. I know now. The code below checks to see if there is a duplicate sales record for a customer when inserting into the table and if there is it redirect to an error page. I want to know if you can do the same for when you are updating a table. // See if that customers sale has already been recorded $sql = mysql_query("SELECT * FROM salesrecord WHERE customer ='$customer' AND value='$value "); $customerMatch = mysql_num_rows($sql); // count the output amount if ($customerMatch > 0) { while($row = mysql_fetch_array($sql)){ $customer = $row["customer"] header("location: sale_error.php?id=$c_id"); exit(); } } Quote Link to comment Share on other sites More sharing options...

kamal213 Posted August 2, 2011 Author Share Posted August 2, 2011 Never mind my code its not really important..I just wanted to know if it was possible. Seen it is possible.. How would you do it. Is it another SELECT sql query? Quote Link to comment Share on other sites More sharing options...
Muddy_Funster Posted August 2, 2011 Share Posted August 2, 2011 @ thorpe :- I was, as was stated previously, simply proffering advice - at no time did I elude to being a member of the forum staff, or atempt to influence an opinion to that nature, I felt that the OP should be aware of the rules. I then so thought to save the OP the trouble of looking these rulles up and included them in thread for their perusal. I do not generaly feel that there is sufficient cause to report an individual for every flaunting of the rules, when normaly an infomative comment is sufficient. If there is something specific that you would like to draw to my attention that has not been covered here in then do please PM me, I was not intending to cause any problems. @kamal213 :- You would run a select on the fields that you want to update, and then compare any result set information that is returned (that which you get back from the database SELECT query) with the variables that you are looking to use in the update. If it is an exact match then you can then decline to run the update. Quote Link to comment Share on other sites More sharing options...

Muddy_Funster Posted August 2, 2011 Share Posted August 2, 2011 No problem, although I'm confident "genius" is a bit strong. I wasn't trying to make you feel bad, just wanted to make you aware was all. No harm no foul. Good luck Quote Link to comment Share on other sites More sharing options...
