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
PL/SQL parameterized cursor with default values A parameterized cursor can have default values for its parameters as shown below: CURSOR cursor_name ( parameter_name datatype := default_value, parameter_name datatype := default_value, ... ) IS cursor_query;Code language: SQL (Structured Query...

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. When a PL/pgSQL variable is substitute...

With the macro, we have a parameterized query but we have lost the information about the dependency chain in USER_DEPENDENCIES, so the second advantage of views is lost. Not only that, but the first advantage is limited as well: currently SQL macros inside WITH clauses are not permitted, ...
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 data server.

Best and Worst Practices ABSTRACT The PL/SQL developer has many constructs for executing SQL statements, and the space of possibilities has several dimensions: embedded SQL versus native dynamic SQL versus the DBMS_Sql API; bulk versus non-bulk; implicit cursor versus parameterized explicit cursor ve...
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. ...
