mysql - Count only unique terms based on inner SELECT JOIN -

-

I'm just trying to calculate unique words as a total number.

This is the original query and it works fine 

  - & gt; Select ('DISTINCT search_tags.term AS t_name, nbr', FALSE) - & gt; From ('search_tags LEFT JOIN (SELECT term as tk, COUNT (search_tags .term) AS NBR FRI search_tag_tag_groups Search_TagTerms) Search_tag on SR SearchTROM = TR.TK') - & gt; Where ('search_tags.dt_added & gt; =', '2011-08-01 09:48:54') - & gt; Where ('search_tags.dt_added & lt; =', '2011-09-02 09:48:54'); // Returns: [Twitter, 12], [Facebook, 6] .....   
 The thing is that this code runs a datatylet (datatable.net) so that the data labels are removed Go to the selected line and change it to:  
  select COUNT (*) LEFT JOIN (from search_tags as numrows (word T, COUNT) (select as search_tags.term) As SR by search_tags.term from the search_tags group) as SR on search_tag.TRM = TR.kk) where `search_tag`.` `Dt_dad``> gt; '2011-08-01 09:48:54' and `search_tag` `Dt_dad``   
 So data formats can count the rows and it can be used as page rotation as the ultimate.  
 But when it takes out the selection, it gets all the rows because DISTINCT is not there anymore.  
 I'm deprived of gold, so I'm stuck trying and error forever. Please help lol: p   
 
 
 resolve  
  -> Selection ('DISTINCT st5.term as T_name, n_ocurrences', FALSE) - & gt; (From "ST4" as the search_tags, select the correct external JOIN (DISTINCT st.term, as the n_ocurrences from search_tags, ST JOIN (duration n_term, COUNT), as st2.term by ST2 Group As search_tags) as st3.n_term = st.term on st3.n_term = st.term where st_t_added> = '$ min' and st.dt_added & lt; = '$ max') on n_ocurrences st3 as st5 on st5.term In = 1 ");   
 Some installation was selected to get the right amount to add. Now I need to count the unique n_ocurrences under $ min, returning the max number as the n_ocurrences only the entire number.

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...

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...
