Splitting one row into mutiple rows

Hi,

I think this should be relatively simple, but i can't for the life of my figure out how to do this.

I've got 4 Columns

Symbol , Price , Vol , Date
Z , 10 , 1 , 1/1/2015
Y , 5 , 3 , 1/1/2015
X , 7 , 2 , 1/1/2016

I just want to split the rows based on the vol column to get

Symbol Price Vol Date
Z , 10 , 1 , 1/1/2015
Y , 5 , 1 , 1/1/2015
Y , 5 , 1 , 1/1/2015
Y , 5 , 1 , 1/1/2015
X , 7 , 1 , 1/1/2016
X 7 1 1/1/2016


I'm thinking I should use an outer join of sorts on one side but i can't remember how to repeat rows.

Any ideas?

Thanks.

VBA Help to read the recordset of a form and create new record

October 25, 2016, 7:44 am

Hi Basically I'm stuck, and need help please

I am using Access 2007, what I am trying to accomplish is this, when an engineer goes out to a service call, the user will fill in the details of the service call via a form, and set the call status from open to complete

If I add "Add New Record" button, to the form, this will indeed generate a new record for this customer/machine, but I have lost the detail to the original record set, for I need to calculate the next service date, from the completion date of the previous record

What I would like if possible!, When the status field is changed from open to complete, I need to read the current form details, create a new record and calculate the next service date e.g. 6 months in the future, and populate the next service date.

Cheers

Using Nested IIF Statement in Query to bring back only records that match

October 25, 2016, 9:36 am
$

Please excuse me if this is a very basic question.

I am writing a query that will become an append query. The field on the form (used in the expression: [Forms]![frmSynMonthYear]![SyndicationMonth]) is the milestone end date that all the tasks (the query that will become an append query). Most tasks are repeated each month but some tasks are quarterly, semi-annual or annual. I wanted to use the values from the tblTaskFeed field "FrequencyID" to filter what is appended for each month. I.e. We will need monthly, quarterly, semi-annual and annual tasks in January; monthly in February, quarterly and monthly in April and so-on.

Here is the nested IIF statement I wrote. It brings back 0 records so obviously I did not write this correctly:

IIF((Month([Forms]![frmSynMonthYear]![SyndicationMonth])=1),(LIKE ([tblTaskFeed]![FrequencyID]=1) AND ([tblTaskFeed]![FrequencyID]=2) AND ([tblTaskFeed]![FrequencyID]=3) AND ([tblTaskFeed]![FrequencyID]=4)),IIF((Month([Forms]![frmSynMonthYear]![SyndicationMonth])=4),(LIKE ([tblTaskFeed]![FrequencyID]=1) AND ([tblTaskFeed]![FrequencyID]=2) AND ([tblTaskFeed]![FrequencyID]=5)),IIF((Month([Forms]![frmSynMonthYear]![SyndicationMonth])=7), (LIKE ([tblTaskFeed]![FrequencyID]=1) AND ([tblTaskFeed]![FrequencyID]=2) AND ([tblTaskFeed]![FrequencyID]=3)),IIF((Month([Forms]![frmSynMonthYear]![SyndicationMonth])=10), (LIKE ([tblTaskFeed]![FrequencyID]=1) AND ([tblTaskFeed]![FrequencyID]=2)),
(LIKE [tblTaskFeed]![FrequencyID]=1)))))

I tried to write it so that if it was a month not listed it would just bring back the monthly tasks only ([tblTaskFeed]![FrequencyID]=1). I added the "LIKE" after reading some suggestions online but it didn't seem to make a difference whether I included it or not.

I also saw suggestions to write a VBA function but I am not sure how to write one correctly or how to call it in the Build Expression box.

I also tried using the SWITCH function which also brought back 0 records.

FYI The [tblTaskFeed]![FrequencyID] field is joined with another table that lists as follows:
ID Frequency
1 Monthly
2 Quarterly
3 Semi-annual
4 Annual
5 Annual (April Only)

Cannot connect to pgbouncer through psql

October 26, 2016, 12:39 am

I am trying to set up connectional pooling using pgbouncer 1.7.2 for PostgreSQL 9.6 on Windows 10.

Trying to connect to pgbouncer in the cmd

psql -p 6432 -h 127.0.0.1 postgres pgbouncer

gives the error:

psql: server closed the connection unexpectedly Server terminated abnormally before or while processing

The port 6432 is listening and looking in the pg_log there are no errors.

Here is my pgbouncer.ini config file:

[databases]

mydb = host=127.0.0.1 port=5432 dbname=mydb

[pgbouncer]

logfile = pgbouncer.log
pidfile = pgbouncer.pid

listen_addr = *
listen_port = 6432

auth_type = md5
auth_file = C:/Program Files/pgbouncer-1.7.2-win32/etc/pgbouncer/userlist.txt

admin_users = postgres, lisam

stats_users = stats, root

Where userlist.txt contains "postgres" "some_password"

In the pgbouncer guide it says:

"Since PostgreSQL 9.0, the text files are not used anymore. Thus the auth file needs to be generated. See ./etc/mkauth.py for sample script to generate auth file from pg_shadow table. PostgreSQL MD5-hidden password format: "md5" + md5(password + username)"

Does anyone know if this is the root of the connection problem and if so how to manually generate the auth file?

Any help would be much appreciated.

Thanks,

Lisa

Slow array_agg after upgrade from 9.2 to 9.5

October 26, 2016, 6:01 am
$
0

Internally we upgraded from 9.2 to 9.5 en we had defined an median function.
This became about 7 to 8 times slower using the same functions.

They are defined like this:


CREATE OR REPLACE FUNCTION public._final_median(anyarray)
RETURNS double precision
LANGUAGE sql
AS
$body$
WITH q AS
(
SELECT val
FROM unnest($1) val
WHERE VAL IS NOT NULL
ORDER BY 1
),
cnt AS
(
SELECT COUNT(*) AS c FROM q
)
SELECT AVG(val)::float8
FROM
(
SELECT val FROM q
LIMIT 2 - MOD((SELECT c FROM cnt), 2)
OFFSET GREATEST(CEIL((SELECT c FROM cnt) / 2.0) - 1,0)
) q2;
$body$
IMMUTABLE
COST 100;


CREATE AGGREGATE median(anyelement)
(
sfunc = array_append,
stype = anyarray,
finalfunc = _final_median,
initcond = '{}'
);

All SQL still work but a lot slower now. Our tables on which we use this function are between 5.000 and 150.000 rows with between 18 and 800 columns.

We found that the median function that fills an array is the slow part. When we change our SQL from median(fieldname) to _final_median(array_agg(fieldname)) the performance is even 3 times faster than on 9.2.

So it looks like the array_agg function when used in a self-defined function is extremly slow.

As we have a lot of files in our ETL proces where a lot of median functions are used we tried to fix this issue instead of altering the median SQL as mentioned above. But we are not yet succeeding.

Anybody had this issue and knows about a way to solve this gracefully?

Adding Autonumber to exiting database that has a manual ref number

Ok, so I was asked to help out a client with there database. They have 400 records and ref numbers allocated to each record. These reference numbers are not in any particular order - (i.e. 1 wasn't the first record entered to the system) Due to Human Errors when allocating ref numbers I've been asked to add an Autonumber Field as REF No. (but making the sure the number itself of the record stays the same)


Sorted the Database by Ref No in Numerical order .... 1,2,3 (keeping in mind that this is not the order they were inputted)

switched to design view, added new field, Auto Ref No - datatype - Autonumber.
Switched back to Datasheet View and it had rearranged the records into order of age - date entered. Meaning my Auto Ref No and My Ref No field aren't matching up.

Is there anyway of avoiding this? Can I set the autonumber to my ORIGINAL numerical order rather than order of RECORD ENTRY DATE?

User defined search Query for Listbox

October 26, 2016, 7:14 am

I'm building a database for a laboratory setting. The operators perform 20 test, and input the data into a form. The table in which it is entered is roughly as below:

DATE | TIME | Test 1 |Test 2 | ... | Test 20

I'm trying to build a form for the supervisor to search for specific ranges with in the tests. Ideally, I'd like for them to enter a date range (via two unbound text boxes - startDate/endDate), and then have text boxes for them to enter the data range they are searching for via other text boxes (StartTest1/EndTest1, StartTest2/EndTest2, ... StartTest20/EndTest20). I was going to build a query in query design view and use the criteria for each field as Between [startDate] and [endDate], then for the fields would be Between [StartTest1] and [EndTest1] Or [StartTest1] Is Null And [EndTest1] Is Null. Sometimes the supervisor will search ranges for one test, but sometimes he/she may need to refine the search based on serveral test. My assumption (and this has worked on a smaller scale) is that this would search the table for records between the dates and with values between whatever information was inputted, unless they were left blank, then it would simply return the records between the inputted dates. If two fields have a start and end value then it would refine the search to fit those criteria with the others left null, and so on. Is there a better way to creating a query to search for this data? When I use the criteria above for more than 8 fields the query seems to lock up.

The query created is to be used to create value in a listbox, which when selected would find that record and allow for the supervisor to edit the record, and also used to create a graph and report.

Any help, or resources to help with this problem would be greatly appreciated.

Thank you

EDIT: I could possibly get this to work by making separate queries to perform the date range, then a query based on the date range query for test 1-5, then another query based on the test 1-5 for test 6-10... etc... but I assume this would be inefficient

T-SQL to strip HTML tags from string without using a function...need straight SQL

Can someone assist me with straight t-sql to strip HTML tags from a string in a column field. will need all variations of HTML tags stripped before exporting to a flat file.
The application sql window does not allow me to create functions since it was created by a third party vendor, but I have access to pull raw data using Putty.

here's an example of a record with HTML tabs:
"<P class=MsoNormal style=""MARGIN: 0in 0in 0pt""><FONT size=3><FONT face=""Times New Roman""><I><U>Watch Hit Information:</U></I><U> </U><?xml:namespace prefix = ""o"" ns = ""urn:schemas-microsoft-com:office:office"" /><o:p></o:p></FONT></FONT></P>
<TABLE class=MsoNormalTable style=""mso-cellspacing: 1.5pt; mso-yfti-tbllook: 1184"" cellPadding=0 border=0>
<TBODY>
<TR style=""mso-yfti-irow: 0; mso-yfti-firstrow: yes"">
<TD style=""BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0; BORDER-BOTTOM: #f0f0f0; PADDIN"

If this data was all in SQL Server I'd have no problems stripping HTML tags with a function, but since its DB2...its a whole new ball game.

Thanks in advance for your assistance

To reduce the impact on the servers and other customer accounts, we had to temporarily disable website and CGI services for your hosting account 'blah'.

I have uploaded sample SQL query which was causing the issue in the file 'sqlquery.txt' in stats folder.

Please administrate your database and address the large queries. These types of queries are often generated by plugins and set to re-occur at regular intervals.
As far as I know, everything has been running smoothly up until this point and I've never had an issue. The problem is, I literally know nothing.... so trying to diagnose the issue seems almost impossible. If I at least knew what was causing the issue, I could repair it.

Here is a dropbox link to the SQL query... if anyone can help shed some light or point me in the right direction it would be greatly appreciated. https://www.dropbox.com/s/00sr7o0869...query.txt?dl=0

Hello,
In PostgreSQL 9.3 I wrote function returnig data from pd_product_comment table + 1 joined field username :
Quote:
CREATE FUNCTION get_new_product_comments() RETURNS SETOF pd_product_comment
LANGUAGE plpgsql
AS $$
declare
r pd_product_comment%rowtype;
begin
for r in
SELECT pd_product_comment.*, pd_ion_users.username as username, pd_ion_users.username as username
FROM pd_product_comment
LEFT JOIN pd_ion_users ON pd_ion_users.id = pd_product_comment.user_id
WHERE pd_product_comment.approved_status = 'N'
GROUP by pd_product_comment.id, pd_product_comment.product_id, username
ORDER BY pd_product_comment.product_id, pd_product_comment.created_at asc
loop
return next r;
end loop;
return;
end
$$;
But I got only fileds of pd_product_comment table, not username field...

So first I want to create a report which displaying all the drivers expenses and gross.
This are the column names examples:

Plate No. | Driver's Name | Gross | 2% | FUEL | FUEL %tage | NET | 11%/12% | Cash Advance | Over

So I already done working with this column but my problem is the Cash advances and Over because this fields are in JDT1 or in Journal Entry Modules in SAP.

My Problem is how can I join the JDT1 table so that I can create formula to get the Over. Or what should I do to create this reports .

Please kindly help me with this problem.
Thanks and Regards in advances.

PostgreSQL states Maximum Columns per Table is 250 - 1600 depending on column types.

Does anyone know the specifics of these limits for each data type? And how it works for tables with multiple column types?
