How to remove ASCII Characters from a string using function

Here is how you can remove ASCII characters from a string in SQL

CREATE FUNCTION [dbo].RemoveASCIICharactersInRange(@InputString VARCHAR(MAX))
RETURNS VARCHAR(MAX)
AS
BEGIN
    IF @InputString IS NOT NULL
    BEGIN
      DECLARE @Counter INT, @TestString NVARCHAR(40)

      SET @TestString = '%[' + NCHAR(0) + NCHAR(1) + NCHAR(2) + NCHAR(3) 
      + NCHAR(4) + NCHAR(5) + NCHAR(6) + NCHAR(7) + NCHAR(8) + NCHAR(11) 
      + NCHAR(12) + NCHAR(14) + NCHAR(15) + NCHAR(16) + NCHAR(17) 
      + NCHAR(18) + NCHAR(19) + NCHAR(20) + NCHAR(21) + NCHAR(22) 
      + NCHAR(23) + NCHAR(24) + NCHAR(25) + NCHAR(26) + NCHAR(27) 
      + NCHAR(28) + NCHAR(29) + NCHAR(30) + NCHAR(31) 
      + NCHAR(127)+ NCHAR(160)+ ']%'

      SELECT @Counter = PATINDEX (@TestString, @InputString COLLATE Latin1_General_BIN)

      WHILE @Counter <> 0
      BEGIN
        SELECT @InputString = STUFF(@InputString, @Counter, 1, '')
        SELECT @Counter = PATINDEX (@TestString, @InputString COLLATE Latin1_General_BIN)
      END
    END
    RETURN(@InputString)
END

Hope this helps 😀

How to omit methods from Swagger documentation on using Swashbuckle

You can add the following attribute to Controllers and Actions to exclude them from the generated documentation

[ApiExplorerSettings(IgnoreApi = true)]

Here is how you can add this on to a controller.

[ApiExplorerSettings(IgnoreApi = true)]
[Produces("application/json")]
[Consumes("application/json")]
[NSAuthorize("Permission", "CanReadResource")]
public class CommonController : BaseController

"There is already an open DataReader associated with this Command which must be closed first."

This can happen if you execute a query while iterating over the results from another query. I ran into this issue when I called another async call while I was executing one result.

public async Task<IActionResult> GetTicketsInventory(int customerID, int accountID)
        {
            var service_response = await this.ticketsService.GetTicketsInventory(customerID, accountID);
            List<TicketsInventoryCO> items = service_response.Response.ToConvert();

               // this is my second call where i am trying to get results based on some condition
               // to get customer names
                var customer_response = await this.customerService.GetAllMobilityCustomers();

            return ProcessServiceResponse(
                apiContext,
                service_response,
                items,
                null);

        }

This can be easily solved by allowing MARS in your connection string. Add MultipleActiveResultSets=true to the provider part of your connection string (where Data Source, Initial Catalog, etc. are specified). Sample connection string

 "CoreCS": "Data Source=xxx.xxx.xxx.xxx;Initial Catalog=Mobility;Integrated Security=False;User Id=sa; Password=xxxxxx;Max Pool Size=20; Connection Timeout=10;MultipleActiveResultSets=true;",

SQL SERVER – How to find table rows count?

At some point in time we’ve all had to find out how many rows are in a table. The first answer you’ll usually get when you ask someone how to do it is select count(*) from table.

Here is the simple and accurate query to get this information from SQL Server

SELECT SCHEMA_NAME(schema_id) AS [SchemaName],
[Tables].name AS [TableName],
SUM([Partitions].[rows]) AS [TotalRowCount]
FROM sys.tables AS [Tables]
JOIN sys.partitions AS [Partitions]
ON [Tables].[object_id] = [Partitions].[object_id]
AND [Partitions].index_id IN ( 0, 1 )
-- WHERE [Tables].name = N'name of the table'
GROUP BY SCHEMA_NAME(schema_id), [Tables].name
order by  [TotalRowCount] desc

How to determine if .NET Core is installed

Here is the info command which includes this information in its output. It will print out the installed runtimes and SDKs, as well as some other info:

dotnet --info

If you only want to see the SDKs: dotnet --list-sdks

If you only want to see installed runtimes: dotnet --list-runtimes
