Re: Use of %p(1)

%SQL is used as a SQL construct - SQL block of a SQL statement. Basically, building blocks of SQL statements, like common where clauses, common selects used within the IN clause, etc

Simple example:

(SELECT 'X' FROM PS_STDNT_ENRL WHERE EMPLID = %P(1)) - saved as ENROLMENT_ROW_EXISTS SQL definition.

This SQL definition can now be used when building other SQL definition and SQL statements. For example, in PeopleCode:

SQLExec("SELECT FIRST_NAME FROM PS_PERSON_NAME WHERE EMPLID IN %SQL(ENROLMENT_ROW_EXISTS, :1)",PERSON.EMPLID, &FIRST_NAME)

Hope this helps!

Use of %p(1)

Hi,

I am trying to use the %p(n) functionality in SQL objects from within a PeopleCode program.

Can you give some examples of how this is used please and how I might be able to use it to dynamically construct the SQL statement conditionally?

I specifically wanted to see if I could use this to pass different clauses to a SQL object, e.g.

SELECT * FROM PS_RECA A
WHERE A.STATUS = 'A'
AND %SQL(%P(1))

Where %P1 can be replaced with something like A.EMPLID IN (SELECT B.EMPLID FROM PS_RECB B).

Any help appreciated.
