https://docs.oracle.com/en/database/oracle/application-express/19.2/aeapi/GET_SESSION_STATE-Function.html#GUID-8BB0C252-C4DB-4300-The correct way to reference the value of a page item in a SQL statement depends on the context of the SQL statement and the type of page item being referenced. Here are the explanations of each of the given options:
A. &PAGE_ITEM This is the syntax for referencing a substitution string in a SQL statement. When a page is rendered, Oracle Application Express (APEX) substitutes the value of a substitution string with the actual value of the page item. However, this syntax is not secure as it exposes the SQL statement to SQL injection attacks.
B. v("PAGE_ITEM') This is the syntax for referencing a bind variable in a SQL statement. A bind variable is a placeholder for a value that is supplied at runtime. The v() function is used to reference a bind variable. This syntax is secure and recommended for referencing page items in SQL statements.
C. APEX_UTIL.GET_SESSION_STATE(p_item => "PAGE_ITEM) This is a PL/SQL function call to the APEX_UTIL package to get the value of a session state variable. This syntax is not recommended for referencing page items in SQL statements because it involves calling a PL/SQL function, which can affect performance.
D. :PAGE_ITEM. This is the syntax for referencing a bind variable in a SQL statement using a colon notation. This syntax is equivalent to the v() function syntax and is also secure.
Therefore, the correct way to reference the value of a page item in a SQL statement is option B or D, depending on the context of the SQL statement. Option A and C are not recommended.
