tiny_tds row count (affected_rows) not working - ruby

Perhaps I misunderstand how to get a count of rows returned by tiny_tds, which talks to ms sql server.
The following code produces -1 rows
sql = "EXEC [Arrivals] #startDate='#{#startDate}', #endDate='#{#endDate}'"
client = TinyTds::Client.new(...)
result = client.execute(sql)
result.each
p result.affected_rows (always returns -1)
This code, using a loop, counts rows correctly:
sql = "EXEC [Arrivals] #startDate='#{#startDate}', #endDate='#{#endDate}'"
client = TinyTds::Client.new(...)
result = client.execute(sql)
#no_of_arrivals = 0
result.each do |row|
#no_of_arrivals = #no_of_arrivals + 1
end
p #no_of_arrivals (returns correct count)
I did see affected_rows in action earlier today, on a table, and it worked. Could it have something to do with the SP... am I missing something obvious?

GORM hangs with parameter

The below queries hangs exactly after 5 calls every time,

Tried even with named parameter, same result
Can anyone help here

CT_FETCH error in PowerBuilder Program

I'm still learning PowerBuilder and trying to get familiar with it. I'm receiving the following error when I try to run a program against a specific document in my database:

Save yourself a ton of headaches and use datawindows... You'd reduce that entire script to about 10 lines of code.
Paul Horan gave you good advice. This would be simple using DataWindows or DataStores. Terry Voth is on the right track for your problem.
In your code, Variable l_pvds_obj_id needs to be the same type as gx_l_doc_obj_id because if you get a result, it will always be equal to it. From the apparent naming scheme it was intended to be long. This is the kind of stuff we look for in peer reviews.
A few other things:
Most of the time you want SQLCode not SQLDbCode but you didn't say what database you're using.
After you UPDATE crt_script you need to check the result.
I don't see COMMIT or ROLLBACK. Autocommit isn't suitable when you need to update multiple tables.
You aren't using most of the values from the first SELECT. Perhaps you've simplified your code for posting or troubleshooting.

Redis Sorted Set: Bulk ZSCORE

How to get a list of members based on their ID from a sorted set instead of just one member?
I would like to build a subset with a set of IDs from the actual sorted set.
I am using a Ruby client for Redis and do not want to iterate one by one. Because there could more than 3000 members that I want to lookup.
Here is the issue tracker to a new command ZMSCORE to do bulk ZSCORE.
There is no variadic form for ZSCORE, yet - see the discussion at: https://github.com/antirez/redis/issues/2344
That said, and for the time being, what you could do is use a Lua script for that. For example:
local scores = {}
while #ARGV > 0 do
scores[#scores+1] = redis.call('ZSCORE', KEYS[1], table.remove(ARGV, 1))
end
return scores
Running this from the command line would look like:
$ redis-cli ZADD foo 1 a 2 b 3 c 4 d
(integer) 4
$ redis-cli --eval mzscore.lua foo , b d
1) "2"
2) "4"
EDIT: In Ruby, it would probably be something like the following, although you'd be better off using SCRIPT LOAD and EVALSHA and loading the script from an external file (instead of hardcoding it in the app):
require 'redis'
script = <<LUA
local scores = {}
while #ARGV > 0 do
scores[#scores+1] = redis.call('ZSCORE', KEYS[1], table.remove(ARGV, 1))
end
return scores
LUA
redis = ::Redis.new()
reply = redis.eval(script, ["foo"], ["b", "d"])
Lua script to get scores with member IDs:
local scores = {}
while #ARGV > 0 do
local member_id = table.remove(ARGV, 1)
local member_score = {}
member_score[1] = member_id
member_score[2] = redis.call('ZSCORE', KEYS[1], member_id)
scores[#scores + 1] = member_score
end
return scores

1 result set from 3 queries?

I'm at my wits end attempting to make this happen. Currently I have 3 separate queries. For automation purposes I need to get the results of these three queries in one output, I cannot seem to join them properly to get the expected results.
QUERY 1:
SELECT OH.EXTN_HOST_ORDER_REF,
OL.EXTN_HOST_ORDER_LINE_REF,
OL.ORIGINAL_ORDERED_QTY,
OL.EXTN_TENDER_QUANTITY,
OL.EXTN_CUM_PICK_QTY,
OL.SHIPPED_QUANTITY,
OL.EXTN_REFUND_QTY
FROM YFS_ORDER_HEADER OH,
YFS_ORDER_LINE OL
WHERE OH.ORDER_HEADER_KEY = OL.ORDER_HEADER_KEY
AND OH.DOCUMENT_TYPE = '0001'
AND OH.EXTN_HOST_ORDER_REF = 'xxxxxxxxxxx'
ORDER BY PL.EXTN_HOST_ORDER_LINE_REF ASC;
QUERY 2:
SELECT RS.STATUS_QUANTITY AS RETURNED_QTY
FROM YFS_ORDER_HEADER OH,
YFS_ORDER_LINE OL,
YFS_ORDER_RELEASE_STATUS RS
WHERE OH.ORDER_HEADER_KEY = OL.ORDER_HEADER_KEY
AND OL.ORDER_LINE_KEY = RS.ORDER_LINE_KEY
AND RS.STATUS = '3700.02'
AND OH.EXTN_HOST_ORDER_REF = 'xxxxxxxxxxx';
QUERY 3
SELECT RS.STATUS_QUANTITY AS CANCELLED_QTY
FROM YFS_ORDER_HEADER OH,
YFS_ORDER_LINE OL,
YFS_ORDER_RELEASE_STATUS RS
WHERE OH.ORDER_HEADER_KEY = OL.ORDER_HEADER_KEY
AND OL.ORDER_LINE_KEY = RS.ORDER_LINE_KEY
AND RS.STATUS = '9000'
AND OH.EXTN_HOST_ORDER_REF = 'xxxxxxxxxxx';
The query should show NULL values where no data exists from query 2 & 3.
Thanks in advance for your help and advice!
If you are allowed to show both returned and cancelled quantities, the following simple edit should work. Hope this helps.
SELECT oh.extn_host_order_ref,
ol.extn_host_order_line_ref,
ol.original_ordered_qty,
ol.extn_tender_quantity,
ol.extn_cum_pick_qty,
ol.shipped_quantity,
ol.extn_refund_qty,
DECODE (rs.status, '3700.02', rs.status_quantity) AS returned_qty,
DECODE (rs.status, '9000', rs.status_quantity) AS cancelled_qty
FROM yfs_order_header oh
INNER JOIN yfs_order_line ol
ON oh.order_header_key = ol.order_header_key
LEFT OUTER JOIN yfs_order_release_status rs
ON ol.order_line_key = rs.order_line_key
WHERE oh.document_type = '0001' AND oh.extn_host_order_ref = 'xxxxxxxxxxx'
ORDER BY pl.extn_host_order_line_ref ASC;

Radix sort not working in Lua

Firstly I should mention I've not been coding very long at all, although that much is probably obvious from my code :P
I'm having two problems, firstly the sort isn't functioning correctly but does sort the numbers by their length. Any help here would be appreciated.
Secondly it's changing both the table it grabs and the table it returns (not sure why). How do I prevent it changing the table it grabs?
I'd prefer if people didn't post a fully optisimised premade code as I'm not going to learn or understand anything that way.
function radix_sort(x)
pass, bucket, maxstring = 0, x, 2
while true do
pass = pass + 1
queue = {}
for n=#bucket,1,-1 do
key_length = string.len(bucket[n])
key = bucket[n]
if pass == 1 and key_length > maxstring then
maxstring = key_length
end
if key_length == pass then
pool = string.sub(key, 1,1)
if queue[pool + 1] == nil then
queue[pool + 1] = {}
end
table.insert(queue[pool + 1], key)
table.remove(bucket, n)
end
end
for k,v in pairs(queue) do
for n=1,#v do
table.insert(bucket, v[n])
end
end
if pass == maxstring then
break
end
end
return bucket
end
There's a lot of changes I made to get this working, so hopefully you can look through and pickup on them. I tried to comment as best I could.
function radix_sort(x)
pass, maxstring = 0, 0
-- to avoid overwriting x, copy into bucket like this
-- it also gives the chance to init maxstring
bucket={}
for n=1,#x,1 do
-- since we can, convert all entries to strings for string functions below
bucket[n]=tostring(x[n])
key_length = string.len(bucket[n])
if key_length > maxstring then
maxstring = key_length
end
end
-- not a fan of "while true ... break" when we can set a condition here
while pass <= maxstring do
pass = pass + 1
-- init both queue and all queue entries so ipairs doesn't skip anything below
queue = {}
for n=1,10,1 do
queue[n] = {}
end
-- go through bucket entries in order for an LSD radix sort
for n=1,#bucket,1 do
key_length = string.len(bucket[n])
key = bucket[n]
-- for string.sub, start at end of string (LSD sort) with -pass
if key_length >= pass then
pool = tonumber(string.sub(key, pass*-1, pass*-1))
else
pool = 0
end
-- add to appropriate queue, but no need to remove from bucket, reset it below
table.insert(queue[pool + 1], key)
end
-- empty out the bucket and reset, use ipairs to call queues in order
bucket={}
for k,v in ipairs(queue) do
for n=1,#v do
table.insert(bucket, v[n])
end
end
end
return bucket
end
Here's a test run:
> input={55,2,123,1,42,9999,6,666,999,543,13}
> output=radix_sort(input)
> for k,v in pairs(output) do
> print (k , " = " , v)
> end
1 = 1
2 = 2
3 = 6
4 = 13
5 = 42
6 = 55
7 = 123
8 = 543
9 = 666
10 = 999
11 = 9999
pool = string.sub(key, 1,1)
always looks at the first character; perhaps you meant string.sub(key, pass, 1)
