sql - Oracle database subquery results in multiple rows -

-

Hi there is a SQL problem, and I hope the answer is very simple.

I have the database with the following structure. 

  State gender birth name calculation ----- --------------- --------- --- --- AC F1923 Helen 15 AKF1926 Helen 35 AKF1927 Susan 25 AKF 1920 Helen has 15 thousand records and I want to see that the output is like this:   < Code> birth name 1910-1911-1912 - & gt; 2012 ----- ------ --------- -------- ------ Helen 5 6 12 800   
 Using MS Access I was able to get some results with it:  
  SELECT DISTINCT as1 birthname AS XP1, (Select the total number from AC AS, where as 1 Birth name = as2.birthname and as1.gender = as2.gender and as1.state = as2.state and as1.birthyear = as2.birthyear and at birth = 1910) as of 1910, (AC Select the total number from AS2 where as1.birthname = as2.birthname and as1.gender = as2.gender and as1.state = as2.state and as1.birthyear = as2.birthyear and at birth = 1911) 1 9 1In the form, select the total number of 2 (from AK), where as1.birthname = as2.birthname and as1.gender = as2.gender and as1.state = as2.state and as1.birthyear = as2.birthyear And birthyear = 2012) as of 2012. AS 1    
 
 
 You should use conditional aggregation:  
  SELECT as1.birthname AS Expr1, SUM (when birthdays = 1910 then `calculation 'and 0 end) as yr_1910, SUM (case when birthdays = 1911 then' calculation 'and 0 end) yr_1911 As, SUM (case when birth time = 1912 then 'counting' and 0 end) yr_1912 to A.K. As AS ASP Group B1 birth place;   
 I'm not sure where  gender  and  state  come from. These are not included in external queries, which are likely to cause your syntax error to include them in aggregation:  
  as1.birthname, as1.gender, as1 State, SUM (case when birthdays = 1910 then 'calculation' and 0 end) as yr_1910, SUM (case when birth = 1911 then 'count' and 0 end) as yr_1911, SUM ( Case when Birthday = 1912 then 'Count' and 0 End) from yr_1912 A.K. AS ASP Group B1 At birth, as1.gender, as1.state;

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...
