SQL Server – How to kill a stored procedure that is in open transaction?

Download SP_WhoisActive from here: http://whoisactive.com/
run it with this query: SP_who is active

the result will show everything that is running at the moment, you will be able to identify your stored procedure being executed.

then execute: kill [request_id of the query above]
the transaction will be canceled.

SQL Server – How to use SQL Profiler to capture a single stored procedure

With the help of SQL Server SQL Profiler, which configuration can be used to monitor a single stored procedure? I would like to capture everything EXEC sprocName include the list of parameters. I would like to capture this procedure to be able to test it using realistic parameter data.

I have tried the following in a new SQL Profiler trace:

Events Selection > Column Filters > Text Data > LIKE: 'exec sprocName%'
Events Selection > Column Filters > Text Data > LIKE: 'exec sprocName'

None of the above configurations capture my procedure. I have also tried to delete the name of the procedure with the following configurations:

Events Selection > Column Filters > Text Data > LIKE: 'exec%'
Events Selection > Column Filters > Text Data > LIKE: 'exec'

The above configurations do not capture any procedure.

Finally, I tried to run the same profile without all column filters and I can confirm that it captures all SQL queries sent to SQL Server.

I envisioned a workaround consisting of capturing ALL of the stored procedure executables and performing a post filter on my sproc of interest, using SQL queries or Excel. Power Query. However, the high frequency of sproc executions in the environment that I want to model makes this operation impractical.

Storing multiple sets of records in a stored procedure

I have already written a store procedure that returns multiple sets of records. I want to call this stored procedure in another storage procedure and store the recordsets for manipulation purposes.

Can any one give me an example on how to declare a variable in a storage procedure that would be suitable for storing 5 sets of records, each set of records containing a different number of columns and recordings with different fields.

openstack – The devstack install procedure on Ubuntu 18.04 LTS fails

this page: https://docs.openstack.org/devstack/latest/

says do the following on a new installation of Ubuntu 18.04LTS (I configure a linode with 4 GB of RAM, 2 core.

  1. sudo useradd -s / bin / bash -d / opt / stack -m stack
  2. echo "stack ALL = (ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
  3. sudo su – stack
  4. git clone https://opendev.org/openstack/devstack
  5. devstack cd
  6. cp samples / local.conf.
  7. ./stack.sh

This lasts a long time, and then ends with the output of the error.

Unfortunately, the article does not show how to see if the system works, nor how to access the user interface. If I hit the IP address of the servers, I see only the default Apache web page, which was not there before the devstack installation.

actual analysis – Evaluate $ lim_ {n rightarrow infty} int_ {0} ^ { pi} frac { sin (nx)} {nx} $. Explanation of some steps of the procedure.

I have been asked to broaden $$ lim_ {n rightarrow infty} int_ {0} ^ { pi} enac { sin (nx)} {nx} dx $$

I have some questions about particular things with the proof, I will write them in bold to differentiate them from the rest of the text.

So we take $ epsilon> $ 0.

We divide the integral as such: $$ lim_ {n rightarrow infty} int_ {0} ^ { pi} frac { sin (nx)} {nx} dx = <l_ {n rightarrow infty} Bigg ( int_ { 0} ^ { epsilon} frac { sin (nx)} {nx} dx + int _ { epsilon} ^ { pi} frac { sin (nx)} {nx} dx Bigg $ $

Treat with $ int _ { epsilon} ^ { pi} enac { sin (nx)} {nx} dx $ first:

We must examine $ frac { sin (nx)} {nx} $. For $ x in ( epsilon, pi) $ we have:

$$ Bigg | frac { sin (nx)} {nx} – 0 Bigg | leq frac {1} {n epsilon} $$

Question 1: Why are we trying to establish this limit? Is it because we want to show that $ frac { sin (nx)} {nx} $ converges uniformly towards $ 0 and as such, be able to apply integral or dominant convergence? if so, how did we get zero? Because I tried to use The Hospital to get a limit and I ended up with a value of $ 1 $ if we differentiate with respect $ x $, the same thing would happen if I differentiated with respect $ n $.

From there, the next step would be:

$$ lim_ {n rightarrow infty} int _ { epsilon} ^ { pi} frac { sin (nx)} {nx} dx leq lim_ { rightarrow infty} int _ { epsilon} ^ { pi} frac {1} {n epsilon} = lim_ {n rightarrow infty} frac { pi – epsilon} {n epsilon} = 0 $$

Question 2: We have established that the upper limit is 0. I suppose that implies that our integral is also going to zero? Is this what we have to accept because it is extremely difficult to explicitly calculate our integral?

From there, a similar procedure would occur with the other part of the integral. The same questions I have about these two steps appear here.

Question 3: What is the purpose of this procedure? Is it because it is an integral difficult to compute explicitly and that as such, we have to find approximate ways to establish what is the integral? Why are we taking the limit to an annoying end point of the internal function?

Note: I am aware that there is a solution to this problem in another article, but I wanted to clarify some of the subtleties that make me dizzy.

Here is the original solution: prove that $ lim_ {n rightarrow infty} int_ {0} ^ { pi} frac { sin (nx)} {nx} dx = 0 $

t sql – Errors when trying to run a stored procedure with a local file output
