Ok, I got it. The {oj is escape sequence for outer join. But why if it is generated by designer can't load anymore again in designer.

Other problem : isnull() from SQL server is equivalent to NVL() in Fox but when i use this in a remote view to SQL server (isnull() to filter null values from SQL server) again test are ok save and at load get the error 'Too many parameters'. Seems the Fox forget the select phraze is for SQL server not for Fox!
