end

@query is your select statement, and you're trying to cast it as a decimal value?


#3

Yes, when i exec @query respose is like 3.00, how to cast it to decimal value?


#4

Ahh I see; you're trying to cast the result of the select. That's not what the code does. I would like to suggest a different way of updating, but before I can do that, I need you to provide:

  • table definitions (of both tables) in the form of create statements
  • sample data in the form of insert statements (so I can validate the code I will be suggesting)
  • expected output from the sample data you provide

If I were to join the two tables, which fields would I use to get a one-to-one relation?


#5

declare @query decimal(18,2) = '2310.45'

select cast(@query as decimal)

hope this is what you are looking for ??
