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
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, ...
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...

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.
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. ...
RazorSQL also offers many other Oracle tools such as a Oracle database browser, a Oracle table editor, an SQL query builder, GUI tools for managing Oracle objects and structures, and much more. See the mainOracle Features Pagefor more information. ...
You can also use TEMPLATE plan guides together with SQL plan guides. For example, you can create a TEMPLATE plan guide to make sure that a class of queries is parameterized. You can then create a SQL plan guide on the parameterized form of that query. ...
