hello,
i find the mistake when i have this error message:
"Objects in this class cannot be updated outside an edit session [TOP10_SIG.DBO.RHAXECEL]".
So i edit the session with arcpy.da.Editor and the script run successfully.
There is th good script:

try:
    axeceau = "RHAXECEL"
    fields = ['CODHYDRO', 'TYPECEAU']
    edit = arcpy.da.Editor(arcpy.env.workspace)
    with arcpy.da.Editor(arcpy.env.workspace) as edit:
        cursor8 = arcpy.da.UpdateCursor(axeceau, fields)
#rows = arcpy.UpdateCursor(axeceau, fields)
        for row in cursor8:
            if row[0] == 3:
                row[1] = 4
            elif row[0] == 4:
                row[1] = 1
            elif row[0] == 5:
                row[1] = 1
            else:
                row[1] = 1
            cursor8.updateRow(row)
except arcpy.ExecuteError:
    print(arcpy.GetMessages(2))
