I have a problem greatest!! I guess that really want Array, look my console when I checked just one:
{"value_solve"=>["", "", "333", ""], "contract_number"=>["33"]}
-----
SQL (317.5ms) UPDATE "authorizations" SET "value_solve" = '', "situation" = 2 WHERE "authorizations"."contract_number" = ? [["contract_number", "33"]]
After, when I checked just one, the first:
{"value_solve"=>["111", "", "", ""], "contract_number"=>["11"]}
-----
SQL (317.5ms) UPDATE "authorizations" SET "value_solve" = '111 ', "situation" = 2 WHERE "authorizations"."contract_number" = ? [["contract_number", "11"]]
And, for last, when I just more then one:
{"contract_number"=>["11", "44"], "value_solve"=>["111", "", "", "444"]}
-----
SQL (297.7ms) UPDATE "authorizations" SET "value_solve" = '111', "situation" = 2 WHERE "authorizations"."contract_number" = ? [["contract_number", "11"]]
SQL (121.9ms) UPDATE "authorizations" SET "value_solve" = '', "situation" = 2 WHERE "authorizations"."contract_number" = ? [["contract_number", "44"]]
And this is my controller:
#selected_ids = params[:authorization][:contract_number]
#authorizations = Authorization.where("contract_number in (?)", #selected_ids)
auth_params = params[:authorization]
auth_params[:contract_number].zip(auth_params[:value_solve]).each do |contract_number, value_solve|
Authorization.where(contract_number: contract_number).update_all(value_solve: value_solve, situation: 2)
end
Just save the first value on DB, how I can save more then one value? Thanks!
As I understood, you want the contract_number with id 44 to be “associated” with value_solve == "444". If this is correct, you should remove blanks from your value_solve array:
auth_params[:contract_number].zip(auth_params[:value_solve].reject(&:blank?))...
Now 44 is being updated with the second element of value_solve, which is apparently an empty string.
See Array#zip for more details.

Running into an odd issue here that I hope you may be able to help me with.
I have a query as part of a set that I want to have update however when I run the query I always get
ERROR: invalid input syntax for type json
DETAIL: The input string ended unexpectedly.
CONTEXT: JSON data, line 1:
SQL state: 22P02
update attendee_data as t set
fname = c.attendee_fname,
lname = c.attendee_lname,
title = c.attendee_title,
email = c.attendee_email,
phone = c.attendee_phone,
company = c.attendee_company,
description = c.attendee_des,
links = CAST(c.attendee_links AS json),
grouplistid = c.attendee_groups,
attendeeonly = c.attendee_atonly
from (values (' Sandy1', 'Abbot', 'Sales Rep', '', '', '', '', '', '', '[{"test":"test"}]', '')) as c(attendee_fname,attendee_lname,attendee_title,attendee_email,attendee_phone,attendee_company,attendee_des,attendee_links,attendee_groups,attendee_atonly,attendee_id)
where CAST (c.attendee_id AS bigint) = CAST (t.sid AS bigint) AND aid = 91848 AND cid= 84616
The above query is test data running directly in PG admin, not sure what I'm doing wrong here but any help would be apreciated!
Thanks.
Is there a way in Erlang to create a select query on ets table, which will get all the elements that contains the searched text?
ets:select(Table,
[{ %% Match spec for select query
{'_', #movie_data{genre = "Drama" ++ '_' , _ = '_'}}, % Match pattern
[], % Guard
['$_'] % Result
}]) ;
This code gives me only the data that started (=prefix) with the required text (text = "Drama"), but the problem is I need also the the results that contain the data, like this example:
#movie_data{genre = "Action, Drama" }
I tried to change the guard to something like that -
{'_', #movie_data{genre = '$1', _='_'}}, [string:str('$1', "Drama") > 0] ...
But the problem is that it isn't a qualified guard expression.
Thanks for the help!!
It's not possible. You need to design your data structure to be searchable by the guard expressions, for example:
-record(movie_data, {genre, name}).
-record(genre, {comedy, drama, action}).
example() ->
Table = ets:new('test', [{keypos,2}]),
ets:insert(Table, #movie_data{name = "Bean",
genre = #genre{comedy = true}}),
ets:insert(Table, #movie_data{name = "Magnolia",
genre = #genre{drama = true}}),
ets:insert(Table, #movie_data{name = "Fight Club",
genre = #genre{drama = true, action = true}}),
ets:select(Table,
[{#movie_data{genre = #genre{drama = true, _ = '_'}, _ = '_'},
[],
['$_']
}]).
MyTable
id | data
___________
1 |[{"Session1": "", "DeviceId1": ""}, {"Session2": "", "DeviceId2": ""}]
I want update data and set Session1 equal to xxx and DevicceId1 eaqual to yyy
I write this query but this not worked
update MyTable data=jsonb_set(data, '{Session1}', 'xxx',true)
How can update value of array of json in PostgreSQL?
data is a json array, so the path to Session1 needs to be {0,Session1}, similarly {0,DeviceId1} for DeviceId1
Which would make the update statement:
UPDATE "MyTable"
SET "data" = jsonb_set(jsonb_set(data, '{0,Session1}', '"xxx"', true), '{0,DeviceId1}', '"yyy"', true)
WHERE id = 1
You can use a json array index (starting from 0) as a path:
update my_table
set data = jsonb_set(data, '{0}', '{"Session1": "xxx", "DeviceId1": "yyy"}')
where id = 1
returning *;
id | data
----+------------------------------------------------------------------------------
1 | [{"Session1": "xxx", "DeviceId1": "yyy"}, {"Session2": "", "DeviceId2": ""}]
(1 row)
I need help designing a query via Active Record & Postgresql.
• The query must search across all of the following columns...
The Model looks like this:
Collection
item_id1: String
item_id2: String
item_id3: String
item_id4: String
item_id5: String
item_id6: String
• The query needs to pass in an array of strings that need to be searched across all of the item_id fields.
• The query must also only return results of Records containing all of the strings within the array.
Note: I also have the Textacular Full Text Search gem installed. However, I tested a search that I believe is supposed to search and return matches only if the records include all of the passed in strings, and the search came up with nothing, despite records with those strings existing in my database. Like this: Collection.advanced_search('B0066AJ5TK&B0041KJSL2')
Just to clarify: You want records where each of the strings in the array are found somewhere within the six item_id fields?
There's probably a more elegant way to do this, but here's what I've got off the top of my head:
terms = ['foo', 'bar', 'baz']
conditions = []
values = {}
terms.each_with_index do |t,i|
arg_id = "term#{i}".to_sym
conditions << "(item_id1 = :#{arg_id} OR item_id2 = :#{arg_id} OR item_id3 = :#{arg_id} OR item_id4 = :#{arg_id} OR item_id5 = :#{arg_id} OR item_id6 = :#{arg_id})"
values[arg_id] = t
end
Collection.where(conditions.join(' AND '), values)
This should produce a query like this:
SELECT "collections".* FROM "collections" WHERE ((item_id1 = 'foo' OR item_id2 = 'foo' OR item_id3 = 'foo' OR item_id4 = 'foo' OR item_id5 = 'foo' OR item_id6 = 'foo') AND (item_id1 = 'bar' OR item_id2 = 'bar' OR item_id3 = 'bar' OR item_id4 = 'bar' OR item_id5 = 'bar' OR item_id6 = 'bar') AND (item_id1 = 'baz' OR item_id2 = 'baz' OR item_id3 = 'baz' OR item_id4 = 'baz' OR item_id5 = 'baz' OR item_id6 = 'baz'))
Which is long and ugly, but should get the results you want.
If you meant that the fields might contain the strings to be searched for, rather than be equal to them, you could instead use
item_id1 LIKE #{arg_id}
and
values[arg_id] = "%#{t}%"
I ran a query as follows:
rs = conn.execute("SELECT * FROM fruits WHERE name = 'apple' AND type = 'sweet'" )
puts "Results = #{rs.inspect}"
this gives me something like
Results = [{"fruitId"=> 123, "name"=>"apple", "type"=>"sweet" }]
How do I get the fruitId out from this?
I tried this:
puts "Retrieved fruitId = #{rs['fruitId'] }"
But that results in an error:
[] no implicit conversion of string to integer
How can I get the fruitId out?
Thanks
You're getting back an array, but you want a hash to be able to use rs['fruitId']. That's what its complaining about.
Try doing this:
db = SQLite3::Database.open "test.db"
db.results_as_hash = true
Source:
http://zetcode.com/db/sqliteruby/queries/
http://www.ruby-doc.org/core-2.0/Hash.html
Its an Array of Hashes. You can access fruitId of the first item in the Array like this
Results[0]["fruitId"]
#=> 123
