Range variable <variable> hides a variable in an enclosing block or a range variable previously defined in the query expression.
A range variable in a query has the same name as a variable previously defined within the same scope, or a range variable previously defined within the query.
Error ID: BC30978
To correct this error
Ensure that all range variables in your query have unique names that do not duplicate existing variable names in the same scope.
Enclose nested queries with duplicate control variable names in parentheses, separating the scope for each range variable.
