            Similar to Other SQL dialects such as TOP() or a LIMIT clause, U-SQL currently offers the FETCH clause.

            The OFFSET/FETCH clause is the ANSI SQL-conformant way to specify getting the first number of rows. If the OFFSET x ROWS clause is not specified, it defaults to OFFSET 0 ROWS. If the FETCH clause is not specified, then all the rows starting after the skipped rows are being returned.

            I have a main form that has buttons on it, and a subform object set to a dynamic sql statement. I set up a private sub for the on_exit of the subform object to grab the seltop and selheight.

            U-SQL random sample of rows
            Asked 2021-Mar-22 at 10:31

            I hope you all can help me.

            What I'm trying to do

            I'm trying to take a random sample from a large Azure database so that I can run the files locally before deploying on Azure cloud. The steps are to first create a pseudorandom number, then just take the first X rows or first X% of rows.

            What I've tried

            I've read several posts including stack overflow SQL, stack overflow SQL 2, SQL select, and USQL Order By Fetch, but still have not figured the syntax out.

            U-SQL has a SAMPLE operator so just add it to the bottom of your statement. For example, this code generates a 10% uniform sample:



            Database locked in when trying to update data in
            Asked 2020-Dec-26 at 19:48

            Hello I have a simple method to update customer details in one of my database tables however when i try to update it an error occurs saying the database is locked. I have no idea how to fix this because my add and delete queries work just fine. This is the error message: System.Data.SQLite.SQLiteException: 'database is locked database is locked'

            You made a good start on keeping your database code separate from you user interface code. However, any message boxes should be shown in the user interface and any sql statements should be written in the data access code.

            I used Using...End Using blocks to ensure that database objects are closed and disposed. I used parameters to protect against sql injection. I am not too sure of the mapping of DbType types to Sqlite types. You might have to fool with that a bit. In you original Update statement you had the ID value in quotes. This would pass a string. When you use parameters, you don't have to worry about that or ampersands and double quotes. Just one clean string.



            How to find unit test dll in Azure Devops when copying test artifact to run on multiple agents (YAML)
            Asked 2020-Jul-08 at 08:07

            I am using Azure Devops YAML build pipeline for the build and test of my SQL SSDT project. I am trying to amend my YAML code so that the test part will run on multiple Microsoft hosted agents (I have purchased 2). When I run the VSTest task as part of the first job that is run on the single agent, it runs no problems. However, when I run it as part of the second job, the unit tests do not run, with an error saying it cannot find the requisite test files. Is there something I need to add to my second job to make this work?

            Many thanks.

            How to find unit test dll in Azure Devops when copying test artifact to run on multiple agents (YAML)

            That because the default Destination directory for the task DownloadBuildArtifacts is $(System.ArtifactsDirectory), however, the default Search folder for Visual Studio Test task is $(System.DefaultWorkingDirectory).

            When you use the those two task in the build pipeline, the value of those two predefined variables are not same:

            The value of $(System.ArtifactsDirectory) should be C:\agent\_work\r1\a.

            The value of $(System.DefaultWorkingDirectory) should be c:\agent_work\1\s.

            So, it will cause this issue, could not found the requisite test files.

            To resolve this issue, we just need to change the default value of those two predefined variables to use same value:



            Join files from different pathes in USQL
            Asked 2020-Jan-30 at 14:24

            My data is saved on a daily basis in the following path: "/Data/{year}/{month}/{day}/mydata.json" So, e.g. "/Data/2018/10/1/mydata.json" , "/Data/2018/10/2/mydata.json", "/Data/2018/11/1/mydata.json", "/Data/2018/12/5/mydata.json", etc.

            I would like to combine all the months and days in one file using USQL. Is it possible to do it in an easy way without mentioning each path separately (otherwise it's crazy to do it for all the days of the year)?
