sql - Selecting all with a length of less than 8 characters, and not null, and not empty -


How do I select all the values ​​that are in length less than 8 characters, and not a zero value and not empty Is value?

This is what I have, but it is still pulling in empty values ​​ 

  select different alphax, case when LAN (termdatex) 8 then the termdatex end termdatex as the table where the termetax is zero and the termdatex is not! = ''    
 
 
 Your problem is in your  case  expression Clearly, when  is not returned as  null  in any of the  sections, then nothing is handled. Here, since you do not filter them in  where , return any string with 8 or more characters as  null  as  case  Expression To correct this, you can move all of your logic to the  where  section:  
  select alphabetically, some decad termetaxes, Where the termdatex is not and nor the wording! = '' And LAN (termdatex) & lt; 8
