mysql - Selecting a GROUP BY statement only when a predicate is true on all grouped fields -

-

I have a table like this: 

  -------- ------ | ID | A. ------------- | 1 | 2 | | 1 | 5 | | 1 | 6 | | 2 | 6 | | 2 | 9 | -------------   
 How can I select all those IDs which have the values ​​of A, which do not include certain numbers, such as I do not want any id for example (9, -1, 20) ID?  
 Thank you!   
 
 
 Believe that you only want id1 because the value of id for id2 is IN (9, -1.20) is what you want:  
  SELECT T1.id, t1.A from my_table t1 join the left my_table t2 at t2.id = t1.id and Select t2.A IN (9, -1, 20) where t2.id is Null   
 or  
  my_table T1 ID where not exist ( Choose from my_table T2 WHERE t2.id = t1.id and t2.A IN (9, -1, 20)) / code>

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...
