tsql - How to concatenate results in T-SQL into column? -

-

I am working on a query for which I should give results: 

 | --name - - | --name | - | - Language-- | --Date - | | James | Hatfield | N, GB, FR | 2011-01-01 | | Lars | Ulrich | GB, FR, CA. 2011-01-01 |  
 But my selection is set as rows:  
 | James | Hatfield | En | 2011-01-01 | | James | Hatfield | GB 2011-01-01 | | James | Hatfield | Fr | 2011-01-01 | | Lars | Ulrich | GB 2011-01-01 | | Lars | Ulrich | Fr | 2011-01-01 | | Lars | Ulrich | Ca | 2011-01-01 |  
 Which best method advises you to change the set of results in values ​​grouped in comma 'grouped in comma to fly?' I've found that implementing a cross can work but people say that this method is very conservative. An additional DB has too much data. Thank you in advance, Regards, Adrian   
 
 
 Here is the best combination method, This will not extend to other XML methods such as special characters:  
  - Integration for XMLand; Destroy the control / encoded four expansions "& amp; & lt; & gt;" Set NOOcount ON; Put your + your values ​​(yourself 1) into your accessible values ​​(2,2, 'B & L; & amp; B; ) Your Talebl value (3.2, enter the 'AAA') @ your Talebl value (4,3, '& lt; br & gt; Enter') your values ​​(5, 3, A and Z) Insert set Nocount off SELECT t1.HeaderValue, CHILDVALUE for STUFF ((T SELECT ',' + t2.ChildValue fROM @YourTable T 2 WHERE t1.HeaderValue = t2.HeaderValue oRDER 2. XML PATH ( '', TYPE) Kvalue ( 'K', 'Varchar (max)), 1,2' ') your baby hair value through T-1 through T-1 group. T1.HeaderValue   
 Output:  
  Header Value Child Value ----------- --------------- 1 CCC 2 AAA, B & Lt; & gt; b 3 & lt; br & gt;, A & amp; Z (3 row)

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...
