sql - Get specified number of rows in Oracle 11g -

-

I want to get the number of rows in the SQL. I use 

  by selecting ROWNUM, FULL_NAME from the command OSQS_INSTITUTION FULL_NAME where between 10 and 20  between ROWNUM  
 and  
 Try the code> ROWNUM, FULL_NAME selections OSQS_INSTITUTION command FULL_NAME limits 10,20   
 and both return the same error  
 
 SQL command properly Not finished   
  edit:   
  stringbilder sqlStatement = new stringbilder (); SqlStatement.append ("SELECT USER_NO, FULL_NAME, active"); SqlStatement.append ("("); sqlStatement.append (Select "USER_NO, FULL_NAME, Active, ROW_NUMBER () Order (FULL_NAME Order) RN"); sqlStatement.append ("from osqs_institution"); sqlStatement Append (") where between rn? And?"); Prepared position pstmt = null; Pstmt = con.prepareStatement (sqlStatement.toString ()); Pstmt.setInt (1, from); Pstmt.setInt (2, from); Rs = pstmt.executeQuery ();   
 Try and hold the necessary.   
 
 
 In the first version, you  the syntax for your query is wrong  After the command, the  where  section is specified.  
 The second version works in MySQL, but not in Oracle  
  
 In any case you can not use it with any rows.  
 Try it instead:  
  with qry AS qry where between 10 and 20 rn   
 you do not use Wish to ROW_NUMBER from the function (select FULL_NAME, ROW_NUMBER (more than the command by FULL_NAME) from the osqs_institute, select RN), FULL_NAME, then try:  
  Select FNL from FULL_NAME (FULL_NAME, from ROWNUM to RN (by selecting the osqs_institution command * by FULL_NAME) where 10 and 20

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...
