sql server 2008 - How to make a SQL table bigger -

-

I have a table with data as 100 rows 

  a1 a2 a3 .. --------- 1 2 3 23 55 4 2 3 7 I use the  UNION ALL  to enlarge that table I'm planning to do  
  a1 a2 a3 ... --------- 1 2 3 23 55 4 2 3 7 1 2 3 23 55 4 2 3 7 1 2 3 23 55 4 2 3 7   
 This is for testing purposes, so what do you suggest, what would be the most effective way to do this?  
 
 
 This will increase the size of your table faster ... earlier this X record, 2x, 4x, 8x Inserts ... If you want to add the same number of records only if you select  different  or  top n , etc.  
  DECLARE @ counts int DECLARE @max int SET @ count int = 1 SET @max = 10 WHILE @ country & lt; Insert in the max @ myTable (a1, a2, a3) select myTable SET @count = @count + 1 END   
 Select A1, A2, A3 from BTW - Not sure what you are trying to test, but you can add anything other than the entire numbers in your data set - like, 1.01, .99, 55.7, 60, etc.  
  Edit   
 For your comment - if you want  actually  to use  union All  then ...  
  enter in myTABLE (a1, a2, a3) to choose from a1, a2, a3 (SELECT a1, a2, a3, myTable UNION Select a1, a2, a3 to myTable UNION ALL select a1, a2, a3 to myTable ...) a

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. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

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...
