let Source = Json.Document(Web.Contents("https://CLUSTER/rest/query?db=MYDATABASE0&csl=.show version",[Query=[#"csl"="let startTime = datetime(2020-06-20); XXXXTable1 | where EventInfo_Time >=startTime | where Environment == 'Prod' | where Hint == ""LeftNav"" and Value in (""True"",""False"") | extend scenario = iff(Value=='True','Treatment','Control') | summarize eventCount=count(),userCount=dcount(Puid) by bin(EventInfo_Time,1d),scenario",#"x-ms-app"="PowerQuery",#"properties"="{""Options"":{""servertimeout"":""00:12:00"",""query_language"":""csl""},""Parameters"":{},""ClientRequestId"":null,""Application"":null,""User"":null,""PrincipalIdentity"":null,""SecurityToken"":null,""AuthorizationScheme"":null,""RequestHostName"":null,""LocalClusterName"":null,""OriginClusterName"":null}"], Timeout=#duration(0,0,12,0)])),

TypeMap = #table(
{ "DataType", "Type" },

Hi @MokaSatya 

 

You can use " & parameterName & ", this parameter needs to return text or you can use Text.From() function around it.

db=MYDATABASE0&csl=.show version",[Query=[#"csl"="let startTime = datetime(" & ParamiterName & ");
