call sys.dm_exec_query_plan for the plan handle of the prepared parameterized query. You can determine whether the query was parameterized by referencing the sql column of thesys.syscacheobjectsview or
of statements or a named PL/SQL block that performs one or more specific functions. It is similar to a procedure in other programming languages. It is stored in the database and can be repeatedly executed. It is stored as a schema object and can be nested, invoked, and parameterized. ...
A static cursor is a cursor whose associated query is fixed at compile time. Declaring a cursor is a prerequisite to using it. Declarations of static cursors using PL/SQL syntax within PL/SQL contexts are supported by the Db2 data server.
As Andrej Pashchenko recently wrote, SQL table macros can get the results we would want from parameterized views (if they existed), but they do not have all the advantages of real views: see https://blog.sqlora.com/en/parameterized-views-with-sql-macros-part-2/ He wants to combine the ...
The query must be a SELECT, or something else that returns rows (such as EXPLAIN). The query is treated in the same way as other SQL commands in PL/pgSQL: PL/pgSQL variable names are substituted, and the query plan is cached for possible reuse. ...

Oracle also determines an execution plan, associates host variables andcursor parameterswith the placeholders in the SQL statement, determines the result set, and sets the cursor to the first row in the result set. More aboutparameterized cursorin the next tutorial. ...
