construct a URL within an SQL statement using the APEX_UTIL.PREPARE_URL function

In Oracle APEX, you can construct a URL within an SQL statement using the APEX_UTIL.PREPARE_URL function. This function helps you generate a valid URL with the necessary session information for APEX applications.

Here's an example of how you can use the PREPARE_URL function in an SQL statement:

1SELECT APEX_UTIL.PREPARE_URL(
2           p_url => 'f?p=' || :APP_ID || ':' || :PAGE_ID || ':' || :SESSION_ID,
3           p_clear_cache => 'YES',
4           p_items => 'P1_ITEM1:' || MY_TABLE.COLUMN1 || ',P1_ITEM2:' || MY_TABLE.COLUMN2) AS generated_url
5FROM MY_TABLE;
6

In the above example, :APP_ID, :PAGE_ID, and :SESSION_ID are bind variables that represent the APEX application ID, page ID, and session ID, respectively. You can replace them with the appropriate values according to your scenario.

The p_clear_cache parameter is optional and specifies whether the APEX session cache should be cleared before generating the URL.

The p_items parameter is optional as well and allows you to pass item values dynamically to the target page. In the example, we concatenate the values from MY_TABLE.COLUMN1 and MY_TABLE.COLUMN2 into the URL parameters P1_ITEM1 and P1_ITEM2, respectively. Adjust the column names and parameters as needed for your case.

The PREPARE_URL function will return the generated URL as the result of the SQL statement. You can include additional columns or conditions in the statement as required.

Remember that this SQL statement must be executed within an APEX application context, either in a PL/SQL process or a SQL report region, for example.
