Mysql Union repeating results -

-

I have a selection of the following, but it repeats the results of the second inner selection 3 times.

Can anyone tell me why this is

Besides, when I get results, how will I know when the result comes from a table? Home_content or facilities_table Choose from 

  select (from hm_id, hm_name, hm_summary, match (hm_name, hm_summary) ('test') as a score from home_content where match (hm_name, hm_summary) Against the score (fac_title, fac_summary) ('test')) against the UNION selection fac_id, fac_name, fac_summary, match (fac_title, fac_summary) match (as opposed to 'test_') (score from facilities_table) DESC < / Code against a command>  
 Thank you in advance   
 
 
 can not see it Why are you getting duplicates? Query:  
     
  1.  There are no duplicates in the source table  
  2.  The same data appears in home_content and facilties_table   
     The second part of the question reads easily to decide which table comes from the union's content, that by adding a continuous column for every question of union, you get something like this: / P> 
      SELECT * ('test') union selection 2, FAP_ID, FAP_NA , Against FAP_sUMRI, FAP (AMMANA, HM_samuri) against a command SCORE DSC  FOP_title, FAP_smurry) The initial column should be 1 for Home_ content table and 2 for the Facilities_ table. Clearly, string constants can be used in the same style, if you are better suited.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
