php - Possible to order an SQL query that matches with a REGEX by the number of matches found? -

-

I am using a SQL query such as WHERE name REGEXP '[[: & lt ;:] ] Some [[:: & gt ;:]] '.

Now all this works very well, but orders are not ordered based on the number of matches of my results, which is what I see.

Thanks

Full Query 

  Select Item.  
 `` `` `` `` `` `` `` `` `` ] '' Or (`item` .`name` regxp '[[:: & lt ;:]] world [[: & gt;:]]')   
 The user is prepared on the basis of input, in each place it divides into a different part that is searched. I would like to order results based on the number of matches of all parts, thus the most relevant results are on top   
 
 < P> I got an UDF sometime back to do this. I'm really sorry I can not quote though the source.  
  DELIMITER // CREATE DEFINER = `Route` @ 'localhost' function 'substrate number' (SVARAR (255), SS VAARAR (255)) Return tint (3) unsigned SQL data The redirection starts is calculated from the tinnitus (3), DECLARE offset TINYINT (3) Uncredited; DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET s = NULL; Set count = 0; Set offset = 1; Repeat if ISNULL (s) and offset & gt; 0 then offset = location (ss, s, offset); If Offset & gt; 0 set count = count + 1; Set offset = offset + 1; end if; end if; ISNULL (s) or offset = 0 until repeat the end; Return calculation; END DELIMITER;   
 There was also a solution to the Nifty.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
