在postgresql中打印变量的值

Question

我有一个postgresql函数

CREATE OR REPLACE FUNCTION fixMissingFiles() RETURNS VOID AS $$
DECLARE
    deletedContactId integer;
    BEGIN
            SELECT INTO deletedContactId contact_id FROM myContacts WHERE id=206351;

            -- print the value of deletedContactId variable to the console

    END;
$$ LANGUAGE plpgsql;

如何将deletedContactId的值打印到控制台？

Answer 1

提出通知：

raise notice 'Value: %', deletedContactId;
