+ * Note about foreign keys constraints: for Dolibarr, since there are a lot of constraints and when imported the tables will be inserted in the dumped order, not in constraints order, then we ABSOLUTELY need to use SET FOREIGN_KEY_CHECKS=0; when importing the sql dump.
+ * Note2: db2SQL by Howard Yeend can be an alternative, by using SHOW FIELDS FROM and SHOW KEYS FROM we could generate a more precise dump (eg: by getting the type of the field and then precisely outputting the right formatting - in quotes, numeric or null - instead of trying to guess like we are doing now).

* @param string $outputfile Output file name
* @param string $tables Table name or '*' for all
* @return int <0 if KO, >0 if OK
