I have a query, when I try to run it commenting a logic defined below, it runs fine.

But I need to include this logic and run the query, the query is taking hell lot of time. 2 hours for 1 lakh record.

Hello,

In my following code, I am getting the error 'Invalid number of arguments':

with Combined as(
      Select staff_name Staff, Status
      from rpt_scheduled_activities
      where trunc(service_date) between '01 aug 2017' and '31 aug 2017'
      and staff_id in (39882, 41116, 45723, 19395, 19365, 63898, 48071,
      55352, 36065, 60240, 62247, 33570, 60693, 61025)
      order by 1)

select
      Staff,
      "'Kept'" as NumKept,
      "'CBT'" as NumCBT,
      "'CBC'" as NumCBC,
      "'DNS'" as NumDNS,
      cast(round((("'Kept'" / NULLIF( ("'Kept'" + "'CBT'" + "'CBC'" + "'DNS'"))*100),2), 0) as varchar(10)) || ' %' as PercentKept
from
(Select * from Combined
PIVOT(count(*) for (Status)
      IN ('Kept', 'CBT', 'CBC', 'DNS')
      ))

I figure the error is somewhere in the 'cast(round...' statement.

Hello,

I have the below search field in my HTML file.

This is connected to a PHP file on Submit.

If the User clicks on 'Search' only, without entering any data, I want all data to be displayed.
Currently, it will only display data it you enter at least one character.

Here is my SQL Select Query within my PHP file.

$query = "SELECT * FROM Products WHERE regexp_like(Title,'$book_name','i')";

i have a asp.net mvc application.

I'm using the Employees table of the SQL Server Northwind database

My table looks like this:

table
Right now my dropdownlist displays  the EmployeeID

My razor code on my view looks like this:

@Html.DropDownListFor(model => model.EmployeeID, "Please Select an Employee: ", new { @class = "employeeclass1", @id = "EmployeeDDL" })


How do i set the default value on page load for my DDL to be 0?
How do I add a "ALL" text to my DDL so if someone selects that then the selected value for that is -2.

So then the only options my DDL would have are:
"Please Select an Employee:"  and the default selected value for this would be 0
"All" and the selected value for this would be -2
The other choices they would have are EmployeeID 1 through 9 which I already have and come from my model.

Is the positioning of the begin try and begin transaction and end try and commit transaction correct? I ask because I sometimes get a message about transaction count being wrong with previous count being 0 and current count being 1.

I am trying to use a query in VBA Access. There is a criteria that involves a Form. As I understand it I have to use Eval for the DAO to understand the query. I have tried but I keep getting errors.

Below is the query, The Normal SQL VBA query, and what I have tried with Eval.  Thanks for the help.

Query:
SELECT SKUs.SKU, SKUs.SkuNm, Assemblies.Quantity
FROM SKUs INNER JOIN Assemblies ON SKUs.SkuID = Assemblies.ChildSkuID
WHERE (((Assemblies.SkuID)=[Forms]![frmPrintChildrenLabels]![txtParent].[value]));

Open in new window


VBA String:
sSQL = "SELECT SKUs.SKU, SKUs.SkuNm, Assemblies.Quantity" _
& " FROM SKUs INNER JOIN Assemblies ON SKUs.SkuID = Assemblies.ChildSkuID" _
& " WHERE (((Assemblies.SkuID)=[Forms]![frmPrintChildrenLabels]![txtParent].[value]));"

Open in new window


What I have tried but compile error expected end of statement:
VBA String:
sSQL = "SELECT SKUs.SKU, SKUs.SkuNm, Assemblies.Quantity" _
& " FROM SKUs INNER JOIN Assemblies ON SKUs.SkuID = Assemblies.ChildSkuID" _
& " WHERE ((([Assemblies].[SkuID])= Eval("[Forms]![frmPrintChildrenLabels]![txtParent].[value]")));"

We are having an issue on our SQL server where jobs that send out a lot of emails send some emails but not all of the them.  In going through the logs the emails are sending fine and report 'Mail successfully sent' and then all of a sudden the error comes up with 'The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 1 (2017-09-18T12:16:43). Exception Message: Cannot send mails to mail server. (The operation has timed out.).).  It seems to fail at different intervals.

On the failure emails, the last_mod_user in the sysmail_event_log is 'sa' and the account_id is NULL.  However, on the successfully sent emails, the last_mod_user is 'DOMAIN\Administrator' and the account_id is 1.  It almost appears as if the Administrator looses connection and then the mail starts failing thereafter.

The same activity seems to happen regardless of running the proc manually or having the agent job initiate it.

The mail settings are (we use AuthSMTP.com to send):

Server Name: mail.authsmtp.com
Port: 2525
SSL: required
Basic Authentication with our AuthSMTP credentials.

Database Mail Executable Minimum Lifetime (seconds) = 600

Does anyone know why this would occur?  

Thank you.

I am trying to add new link server to oracle db in SSMS. I've installed oracle client 12c 64 bit.
I can connect to the oracle db via SQL developer when I enter the tnsnames directory but not mgt studio, when adding a new linked server. This confirms all service names passwords and firewall rules, content of tnsname.ora are correct. I get "ORA-12154 tns could not resolve the connect identifier specified" immediately so its not finding the tnsnames.ora file.

So I have also checked the following:
I have amended the provider options to allow inprocess.

My tnanames.ora and sqlnet.ora files are in c:\oracle\product\12.2.0\client_1\network\admin\

I have names.directory_path= (Tnsnames) in my sqlnet.ora file.

If I do a tnsping tnsentry it uses the above sqlnet.ora as parameter file bit I get
tns-03505: failed to resolve name error

Ive check the path in environment variables. In regedit, the path of Inprocserver32 of the oracle clsid is c:\oracle\product\12.2.0\client_1\bin\oraOlEDB12.dll

Ive restarted SQL services.

How can I get SQL mgt studio to point.to my tnsnames file.?  Is there anywhere in regedit that tells SQL of the file location

I've just run a SQL command something like this and discovered  I have trailing white space in  file.path  how do I remove it?

select m.id ,m.title,m.tmdbid,m.imdbid,mlf.fileid,f.path from movie m,movielinkfile mlf,file f where m.id=mlf.movieid and mlf.fileid=f.id and  f.path like '%My Film Name%' order by m.title

Open in new window


Resulting in
--m.id ,m.title,m.tmdbid,m.imdbid,mlf.fileid,f.path
"2407","My Film Name","","","2569","Path1/to/My Film Name.mp4"
"2407","My Film Name","","","4850","Path2/to/My Film Name.mp4
" -- trailing white space
"3837","My Film Name","1234","tt123456","5318","Path2/to/My Film Name.mp4"

Open in new window


This means movie.id 3837 is a duplicate of movie.id2407 but wasn't picked up because of the trailing white space  not sure if '\n,CR or LF'

if possible before removing 3837 I'd like to grab the m.tmdbid,m.imdbid values and update 2407 if NULL  the only thing that links the 2 is "path2/to/My Film Name.mp4"

I think there is over 500 duplicates with  trailing white space every thing with a f.id >= 5216 maybe duplicate and have entries for  m.tmdbid,m.imdbid and <= 5216 may or may not have  m.tmdbid,m.imdbid values

Primarily after Removing the duplicate 3837 I then need to remove the trailing white space from f.path I can't do it before because it's indexed and won't allow duplication

Hello everyone!

I am running with TFS 2015.3, and SQL Server 2016 SP1, in separate servers.

Recently, I change our production TFS Database from 32 bit to 64 bit (for updating purposes), and I believe we loose some database configuration and permissions.

This week (after the change), we are having some issues with some Jobs, related to Warehouse and Coverage Analysis:

-Work Item Tracking Warehouse Sync
-Test Management Warehouse Sync
-Team Foundation Server Coverage Analysis

The error that is shown is:

Microsoft.TeamFoundation.Framework.Server.DatabaseOperationTimeoutException: TF246018: The database operation exceeded the timeout limit and has been cancelled. Verify that the parameters of the operation are correct. ---> System.Data.SqlClient.SqlException: Execution Timeout Expired.

So if that list generates a list of 10 names and John Doe appears twice, I only want that name to appear once. Is it Group BY and how do you add that into a Wordpress Query?

Good Afternoon

I am using an Oracle Form (10g) and I would like to return multiple records in a field rather than just returning one row.  I tried Bulk Collection but I received a client side error.

Hello - need assistance with writing a nested IIF statement in a MSACCESS query

Here is what I am trying to do:

If COMPONENT = MED, then I need to look at the difference between REFILLS ALLOWED and REFILLS REMAINING.  If they are equal numbers the result will be START. If they are not equal, then result should be "REFILL"

If COMPONENT IS NOT "MED", then need to look at the difference between REFILLS ALLOWED and REFILLS REMAINING.  If the difference between  REFILLS ALLOWED and REFILLS REMAINING is -1, Then  the result will be START. If the difference is more than 2, then result should be "REFILL".  

Note: REFILLS ALLOWED will always have a bigger number than Refills Remaining.

I tried.... but this does not work....
STATUS: IIf([COMPONENT]= "MED"& [REFILLS_ALLOWED] = [REFILLS_REMAINING], "START",REFILL",IIf([COMPONENT] NOT "MED" & [REFILLS_ALLOWED] = [REFILLS_REMAINING] -1, "START", IIf([COMPONENT] NOT "MED" & [REFILLS_ALLOWED] = [REFILLS_REMAINING] >-2, "REFILL",

EXAMPLE
Component    Refills Allowed         Refills Remaining             Status
   MED                    3                                    3                                START
    SOL                     3                                    2                                START
    MED                   3                                     1                                 REFILL
    MED                   2                                     0                                REFILL…
