左联接-联接表翻倍结果

Question

this is my query with two left joins (tried to join bcompany - main table WITH bpoint, bug):

SELECT cName, sName, uNaslov FROM bcompany c LEFT JOIN bpoint p ON c.companyID = p.companyID LEFT JOIN bug b ON c.companyID = b.companyID WHERE c.companyID='$cID'

First table bcompany is a main one, and there is always exactly one result row.

Both tables bpoint and bug relate to bcompany via the companyID column. These two tables will not necessarily have any records.

My problem are doubled results of those two joined tables. I can understand multiple results for the main table, but not for the joined two.

Table structure:

bcompany:

companyID |       cName         |
---------------------------------
    1     | Mladi Tehnik d.o.o. |

bpoint:

pointID |      sName          | companyID |
-------------------------------------------
   1    |    Mladi Tehnik     |     1     |
   2    |    Pizzerija 5ka    |     1     |
   3    |    Gostilna Kekec   |     1     |
   4    |    Blejski tehnik   |     1     |

bug:

bugID | uNaslov       | companyID |
-----------------------------------
  1   |  Testna 1     |     1     |
  2   |  Testna 2     |     1     |
  3   |  Mickino kolo |     1     |

Answer 1

The result is ok. If there were only one entry in the bpoint column the result would be inconsistent because there is one "Mladi Tehnik doo" with "Mladi Tehnik" and the exact same one without a bpoint entry.
