17.13. The operator of reading the line on the cursor associated with a dynamically prepared sample statement

  <dynamic fetch statement> :: =
    FETCH [[<<fetch orientation>] FROM]
   <dynamic cursor name> <using clause> 

Comment:

In fact, the read statement on the cursor associated with a dynamically prepared SQL statement differs from the static case only by the possible presence of the using clause, which specifies the location of the values ​​of the current row in the resulting table. In addition, the cursor name can be specified through a variable.
