17.15. The positional delete operator on the cursor associated with a dynamically prepared sample operator

Lecture



  <dynamic delete statement: positioned> :: =
    DELETE FROM <table name>
    WHERE CURRENT OF <dynamic cursor name> 

Comment:

In fact, the positional delete operator on the cursor associated with a dynamically prepared SQL statement differs from the static case only in that the name of the cursor can be specified through a variable.
