17.12. The operator to open a cursor associated with a dynamically prepared sample statement

  <dynamic open statement> :: =
    OPEN <dynamic cursor name> [<using clause>] 

Comment:

In fact, the opening statement of the cursor associated with a dynamically prepared SQL statement differs from the static case only by the possible presence of a using clause, in which the actual parameters of the select statement are set. In addition, the cursor name can be specified through a variable.
