I want to write this kind of a MySQL query.
select image_path, replace(replace(replace(description,\'/images/\',image_path),\'<![CDATA[\',\'\'),\']]>\',\'\') description from test_image_master where ...
If I echo this query from php it is showing like this
select image_path, replace(replace(replace(description,'/images/',image_path),'','') description from test_image_master where ...
Missing <![CDATA[ and ]]>. So the query is not working properly.
I am using php and mysql.
How can I solve this?
It won't miss. You just can't see from browser, you can check the source of html.

I have tried it in several ways but it doesn't work (seems like ignoring it). So what I tried:
$user->notes()->groupBy('title')->get();
Above way completely ignores groupBy and just returns collection of notes.
Note::where('user_id', $user->id)->groupBy('title')->get();
Exactly same output with this one too.
In my database.php, the database is set to 'strict' => false
I have also tried using raw db query, it returns it in a weird format (returns 1 row for each title when I use groupBy)
DB::table('notes')->where('user_id', $user->id)->groupBy('title')->get();
I have seen many people facing this issue however none of the suggested ways (above) solved the issue.
I can achieve what I want with using collection->each(function ($note) {...} ), however while there is groupBy to make achieve this easily with 1 line, why the heavy work..
Does anyone has any idea why it doesn't work?
you just need to call first the ->get() then the ->groupBy() method.
Thats because in a SQL Query you need to select first the elements, then group.
So your code need to be like:
DB::table('notes')->where('user_id', $user->id)->get()->groupBy('title');
Heres an example of a Group By Query:
SELECT column_name(s)
FROM table_name
WHERE condition
GROUP BY column_name(s)
ORDER BY column_name(s);
go with select() and please add your group by field in select
e.g DB::table('notes')->select('title','Other_field')->where('user_id', $user->id)->groupBy('title')->get();
I have already gone through part of the process to convert my text to a proper date:
7-jan -> 7-1 -> 7-1-2014
(note: dd-mm-yyyy)
However, I am now required to change the 7-1-2014 format to 07-01-2014 in order to change the text to a date.
Is there an easy way to do this?
Am not too experienced but have a basic understanding of queries and functions.
you're looking for something like this :
select STR_TO_DATE('7-1-2017', '%d-%m-%Y')
Try this:
SELECT STR_TO_DATE('7-1-2014', '%e-%m-%Y');
SELECT STR_TO_DATE('7-Jan-2014', '%e-%M-%Y');
I have the following query:
INSERT INTO insertlog (Inforamtion) VALUES (
concat("Row Was Inserted",curdate());
MySQL is returning an error, but I cannot figure out why. My google searches do not show examples on how to perform something like this.
use it simpler like that
INSERT INTO insertlog (Inforamtion)
SELECT concat("Row Was Inserted ",curdate()) ;
be sure if your column is Information or Inforamtion
your query also works but you missed ) in the end . here demo with both solutions :

I think you are missing one closing )
Moreover as Bill pointed, you may have spelled your column name incorrectly - information
I'm using Rails 3 with a MySQL database, and I need to programmatically create a query like this:
select * from table where category_name like '%category_name_1%'
OR category_name like '%category_name_2%'
(...snip...)
OR category_name like '%category_name_n%'
Given the table size and the project scope (500 rows at most, I think), I feel that using something like thinking sphinx would be overkill.
I know I could simply do this by writing the query string directly, but wanted to know if there's an ActiveRecord way to do this. There's no mention of this on the official guide, and I've been googling for a long while now, just to end empty-handed :(
Also, is there a reason (maybe a Rails reason?) to not to include the OR clause?
Thanks!
Assuming you have an array names with category names:
Model.where( names.map{"category_name LIKE ?"}.join(" OR "),
*names.map{|n| "%#{n}%" } )
you should google first, there is already an answer.
Look here and then here
and you'll get something like this:
accounts = Account.arel_table
Account.where(accounts[:name].matches("%#{user_name}%").or(accounts[:name].matches("%#{user_name2}%")))
If you look at the guide, they have examples that can easily be modified to this:
Client.where("orders_count = ? OR locked = ?", params[:orders], false)
Mysql has a regexp function now that can clean things up a bit, assuming there's no regex metachars in your category names:
Table.where "category_name regexp '#{names.join('|')}'"
I have a query in mySQL that's meant to return search terms that are used on our site. Yes, this is for a tag cloud, and yes, I know it's a mullet :)
We've got an admin page where administrators can view search terms and choose to exclude them from showing up in the cloud. These words go into the "badWords" table. We've gotten some terms like "foo%2525252525252520bar", and we're having trouble getting those excluded.
In pseudocode, the query to get the search terms for the cloud is:
SELECT * FROM `searchTerms` WHERE `word` NOT IN ( SELECT `word` FROM `badWords` )
This works fine, unless one of the terms returned from the subquery has a % in it. Is there a way to escape the entire subquery? I've tried doing a
replace( SELECT `word` FROM `badWords`, '%', '\%' )
... but that's apparently not syntactically correct.
I can do two queries if need be, but wondered if there's a way to get it done as is.
Thanks!
==============================
UPDATE: closing this for now, as I think the error lies elsewhere. Will report back once I know for sure, but don't want folks wasting time answering the question here if it's not the correct question...
Upvoted both of the replies received so far. Thanks, guys.
==============================
UPDATE 2: sigh Nevermind... can't close it :\
==============================
FINAL UPDATE: Well, looks like escaping the value isn't the problem. The admin page passes the value in the URL before it's added to the badWords table. In passing the value via the URL, it changes. So what's added to badWords is actually "foo%25252525252520bar" (there's one less "25" sequence). If I manually update the value in badWords and add back the missing "25" it works as expected. So no need to replace or escape anything. I just need to fix those URL values properly.
==============================
I don't think the % is your problem here. I think that you're trying to use REPLACE() on the subquery itself (SELECT ...), and not on a column value (word). Try this instead:
SELECT * FROM `searchTerms`
WHERE `word` NOT IN (
SELECT REPLACE(`word`, '%', '\%') AS word FROM `badWords`
);
Good luck!
I'm not very good with MySQL syntax, but SQL Server let's you do it this way:
SELECT * FROM `searchTerms` WHERE `word` NOT IN ( SELECT REPLACE(`word`, '%', '\%') FROM `badWords` )
NOTE: Basically all I did was move your REPLACE over some =) Hope this helps.
