=============
Query Tabular
=============

**Inputs**

  Loads tabular datasets into a SQLite_ data base.  

  An existing SQLite_ data base can be used as input, and any selected tabular datasets will be added as new tables in that data base.


**Outputs**

  The results of a SQL query are output to the history as a tabular file.

  The SQLite_ data base can also be saved and output as a dataset in the history.  

    *(The* **SQLite to tabular** *tool can run additional queries on this database.)*


For help in using SQLite_ see:  http://www.sqlite.org/docs.html

**NOTE:** input for SQLite dates input field must be in the format: *YYYY-MM-DD* for example: 2015-09-30

See: http://www.sqlite.org/lang_datefunc.html

**Example** 

  Given 2 tabular datasets: *customers* and *sales*
  
   Dataset *customers*
  
    Table name: "customers"
  
    Column names: "CustomerID,FirstName,LastName,Email,DOB,Phone"

  The query
  
  ::
  
    SELECT FirstName,LastName,sum(SaleAmount) as "TotalSales" 
    FROM customers join sales on customers.CustomerID = sales.CustomerID 
    GROUP BY customers.CustomerID ORDER BY TotalSales DESC;
  
  Produces this tabular output:
  
    ========== ======== ==========
    #FirstName LastName TotalSales
    ========== ======== ==========
    James      Smith    555.55
    Paula      Brown    222.95
    Steven     Goldfish 100.22
    John       Smith    99.95
    ========== ======== ==========
  
  
  If the optional Table name and Column names inputs are not used, the query would be:
  
  ::
  
    SELECT t1.c2 as "FirstName", t1.c3 as "LastName", sum(t2.c3) as "TotalSales" 
    FROM t1 join t2 on t1.c1 = t2.c1 
    GROUP BY t1.c1 ORDER BY TotalSales DESC;
  
  You can selectively name columns, e.g. on the customers input you could just name columns 2,3, and 5: 
  
    Column names: ,FirstName,LastName,,BirthDate
  
    Results in the following data base table
  
    =========== ========== ========== ===================== ========== ============
    #c1         FirstName  LastName   c4                    BirthDate  c6

    SELECT t1.FirstName, t1.LastName
    FROM t1
    WHERE re_match('^.*\.(net|org)$',c4)

  Results:
