I am trying to replace a table in a SQL query dynamically in ADF pipeline. I tried these queries to get it:

select * 
from c 
where timestampToDateTime("@{concat(variables('lastUpdatedColumn'),'*1000')}") < 
"@{formatDateTime(utcnow(),'yyyy-MM-ddTHH:mm:ss.fffffffZ')}"

select * 
from c 
where TimestampToDateTime(variables('lastUpdatedColumn')*1000) < 
"@{formatDateTime(utcnow(),'yyyy-MM-ddTHH:mm:ss.fffffffZ')}"
 

But both queries are returning the same output – shown here:

 "select * from c where TimestampToDateTime("c._ts*1000") < "2024-07- 
  24T13:03:24.6140044Z"",

It is being replaced with “c._ts*1000” . But I want to remove those slashes(,/). How could we remove those? Thanks in advance
