wordpress - Based on the following MYSQL query how can I write an UPDATE statement to update a value? -

-

I am using the following SQL query to get a record from a WordPress database. 

  select p.id, p.post_title, m.meta_key, m.meta_value, t.slug wp_posts p at p.id = m.post_id and m.meta_key = wp_postmeta meter Join '_ subscription_sign_up_fee' internally as wp_term_relationships p.id = tr.object_id on TR included in the form of TT tr.term_taxonomy_id = tt.term_taxonomy_id on the inside wp_terms tt tt.term_id = t.term_id t on t wp_term_taxonomy. Slug = 'bundle' is included in the form   
 My problem is that I need to increase the value of _subscription_sign_up_fee to 100.  
 I tried the following  
  wp_postmeta set up wp_postmeta.meta_value = wp_postmeta.meta_value + 100 INNER JOIN wp_postmeta wp_posts.id = m.post_id and m.meta_key = Join '_lib_sign_up_fee' inner wp_posts.id = tr.object_id as tr in inner wp_term_taxonomy Join tr.term_taxonomy_id = tt.term_taxonomy_id as tn.term_id = t.term_id at t as ASNER JOIN wp_terms t.slug = ' The bundle is saying 'column' meta_value 'is obscure in the field list.' I am very sorry to get an error that I do not understand surnames, is there any issues Can you point in the right direction?   
 
 
 To add a MySQL update, SET is finished on the right syntax. . You also have some problems in that you are joining wp_postmeta twice, but lost to join wp_posts  
 should work like this; Add wp_posts.id = m.post_id and m.meta_key = '_subscription_sign_up_fee' on the basis of the updated wp_postmeta meter wp_posts add wp_posts.id = tr.object_id as tr as wp_term_taxonomy form TT at TR.term_taxonomy_id Ttm.tm_taxonomy_id JT wp_terms TT as T. Tm_id = t term_id set m.meta_value = m.meta_value + 100 ou t.slug = 'bundle'   
 ... and always before randomly running potentially devastating operations from your data Remember to take a backup of the Internet :)

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
