Well I think it's a simple question but I could not found the solution.

Well I have three Tables:

T开发者_StackOverflow社区able 1

id(AS t1id)    Name  LASTNAME Value 

1              a     z         50

2              b     e         60 

3              c     k         70

4              d     u         60

Table2

id   idTable1   Name(AS t2me)   Value(AS t2ve)

1     1          er             50

2     1          zx             150

3     2          zc             300

Table 3

id   idTable1   Name(AS t3me)   Value(AS t3ve)

1     2         erxc   50

2     2         zvvx   150

3     2         zcz    300

How to get this result with SQL

t1id    Name      LASTNAME   t2me    t2ve     t3me     t3ve

1       a         z           er      50      erdxc    150

1       a         z           zx      150           

2       b         e           zc      300      erxc    50

2       b         e                            zvvx    150

2       b         e                            zcz     300

Is that possible? If not what could I do?


SELECT t1.id as t1id, t1.Name, t1.LASTNAME, 
    t2.Name as t2me, t2.Value as t2ve, t3.Name as t3me, 
    t3.Value as t3ve from Table1 t1 
LEFT JOIN Table2 t2 on t1.id = t2.idTable1 
LEFT JOIN Table3 on t3.idTable1 = t1.id
