Check that insert/update fields are from the same single table of a view.
SYNOPSIS
check_view_single_update()
fields The insert/update fields to be checked.
view The view for insert.
map [in/out] The insert table map.
DESCRIPTION
This function is called in 2 cases:
1. to check insert fields. In this case *map will be set to 0.
Insert fields are checked to be all from the same single underlying
table of the given view. Otherwise the error is thrown. Found table
map is returned in the map parameter.
2. to check update fields of the ON DUPLICATE KEY UPDATE clause.
In this case *map contains table_map found on the previous call of
the function to check insert fields. Update fields are checked to be
from the same table as the insert fields.
RETURN
0 OK
1 Error
