Found solution, the right syntax is:
SELECT hl7incom.id
FROM hl7incom, pid_segment
LEFT JOIN pid_segment
ON hl7incom.id = pid_segment.id
WHERE hl7incom.msg LIKE '%PID%'
AND pid_segment.id IS NULL;
Cheers for try of help,

Same result, also if I do not define unique index.
Just a
I have two tables
CREATE TABLE pid_segment (
id INT NOT NULL UNIQUE PRIMARY KEY,
msg TEXT)
TYPE=INNODB
CREATE TABLE hl7incom(
id INT NOT NULL AUTO_INCREMENT UNIQUE PRIMARY KEY REFERENCES pid_segment
(id).
msg TEXT,
time TIMESTAMP NOT NULL)
TYPE=INNODB

Just a suggestion:
SELECT hl7incom.id
FROM hl7incom, pid_segment

AND not(pid_segment.id = hl7incom.id)
GROUP BY hl7incom.id;
Otherwise my only other suggestion would involve using the 'NOT IN'
logic, but I
