# apex_plugin_util.is_component_used
I asked to have APEX\_PLUGIN\_UTIL.IS\_COMPONENT\_USED officially documented. So, it happened, sort of:
[https://docs.oracle.com/en/database/oracle/apex/22.2/aeapi/IS\_COMPONENT\_USED-Function.html#GUID-7BE7EA7C-DCBA-4940-8FC8-8F6EB849E3AE](https://docs.oracle.com/en/database/oracle/apex/22.2/aeapi/IS_COMPONENT_USED-Function.html#GUID-7BE7EA7C-DCBA-4940-8FC8-8F6EB849E3AE)
The documentation is essentially this:
```sql
APEX_PLUGIN_UTIL.IS_COMPONENT_USED (
p_build_option_id IN NUMBER DEFAULT NULL,
p_authorization_scheme_id IN VARCHAR2,
p_condition_type IN VARCHAR2,
p_condition_expression1 IN VARCHAR2,
p_condition_expression2 IN VARCHAR2,
p_component IN VARCHAR2 DEFAULT NULL )
RETURN BOOLEAN;
```
What does it do?
Essentially, this is the function that is used for APEX server side conditions. If you pass in the same kinds of things you pass in for a server side condition, you get a TRUE or FALSE response. You never get null. You get TRUE if it is true, and FALSE if it is not true.
You might want a wrapper function that returns a Y or N:
```sql
create or replace function is_component_used_yn (
p_build_option_id IN NUMBER DEFAULT NULL,
p_authorization_scheme_id IN VARCHAR2,
p_condition_type IN VARCHAR2,
p_condition_expression1 IN VARCHAR2,
p_condition_expression2 IN VARCHAR2,
p_component IN VARCHAR2 DEFAULT NULL )
return varchar2 is
begin
return case when
apex_plugin_util.is_component_used (
p_build_option_id => p_build_option_id,
p_authorization_scheme_id => p_authorization_scheme_id,
p_condition_type => p_condition_type,
p_condition_expression1 => p_condition_expression1,
p_condition_expression2 => p_condition_expression2,
p_component => p_component)
then 'Y'
else 'N'
end;
end is_component_used_yn;
```
As you can see, the documentation leaves a little to be desired. Most importantly, what are the allowable values for p\_condition\_type? Well, you asked (or I did) so here is the answer:
```xml
```
Yep, I just inspected a page from the builder and grabbed the HTML behind select list.
Just to put everything in one place, here is the associated help:
