INSERT INTO `documentcounters`
(`DataChar`,`SeqNum`,`LastSignature`,`DocumentType`,`SalesTerminal`,`Active`)
SELECT Q1.in_headers, -1,NULL, 17,0,0 FROM
(SELECT DISTINCT(DocumentSeries) as in_headers FROM transactionsheaders )AS Q1
LEFT JOIN
(SELECT DISTINCT(DataChar) as in_counters FROM documentcounters)AS Q2
ON Q1.in_headers=Q2.in_counters WHERE Q2.in_counters IS NULL;
Cela fonctionnera si UID
est défini comme auto_increment
