Create parameterize with Snowflake as like MySQL and SQL Server. Need to pass the values from .NET Snowflake .NET Connector.

https://www.mssqltips.com/sqlservertip/2981/using-parameters-for-sql-server-queries-and-stored-procedures/

Query with value:

select * 
from "SNOWFLAKE_SAMPLE_DATA"."TPCDS_SF100TCL"."WEB_SITE" 
where ((Web_REC_START_DATE is null and IFF('2000-08-16' is null,true,false))    
       or Web_REC_START_DATE > '2000-08-16')

How to use SqlDataReader with a parametrized query in c#?

Query with names of parameters:

select * 
from "SNOWFLAKE_SAMPLE_DATA"."TPCDS_SF100TCL"."WEB_SITE" 
where ((Web_REC_START_DATE is null and IFF(@StartDate is null,true,false)) 
       or Web_REC_START_DATE > @StartDate)

the snowflake .net connector, is hosted in github, and it's read me describes how to in the bind-parameter section

so looking at the tests in the code, specifically the BindTest line 75

it shows named parameters being used. thus:

command.CommandText = "insert into TEST_TBL values(:p0)";
var param = command.CreateParameter();
param.ParameterName = "p0";
param.DbType = System.Data.DbType.Int32;
param.Value = DBNull.Value;
command.Parameters.Add(param);
