My Join in Sql is not working

[Marc Venken]

Hello,

Normaly this should be easy, but I didn't find it yet... I have looked at samples Maria02 and 05 but still ...

Here is the code

Code: Select all  Expand view

function Main()

  local oRs, cSql

  Public cServer     := ""
  Public cDataBase   := ""
  Public cUser       := ""
  Public cPassWord   := ""
  Public oCn, oRsATT, oRsVolgorde

  FWCONNECT oCn HOST cServer USER cUser PASSWORD cPassword DATABASE cDatabase

  if oCn == nil
     ? "Failed to connect"
     return nil
  endif

  cZoekProduct := "77"

  oRsProduct := oCn:RowSet( "SELECT * FROM ps_product_lang where id_lang = ? ", { "1" } )

  oRsGroepen:= oCn:RowSet( "SELECT * FROM `ps_category_lang` where `id_lang` = ? ", { "1" } )

  oRsvolgorde:= oCn:RowSet( "SELECT * FROM `ps_category_product` where `id_category` = ? ", { cZoekProduct } )

//  oRsvolgorde:= oCn:RowSet( "SELECT * FROM, P.description_short as PName from ps_category_product C LEFT JOIN ps_product_lang P on C.id_product where id_category = ? " )

In the second browse, the name is not changed, because It need to come from ps_products_lang

I am not sure about your problem, the only join i see is :

Code: Select all  Expand view

SELECT * FROM, P.description_short AS PName FROM ps_category_product C LEFT JOIN ps_product_lang P ON C.id_product WHERE id_category = ?

and here I think there it was a "paste" in the wrong place, maybe you want write:

Code: Select all  Expand view

SELECT *,P.description_short AS PName FROM ps_category_product C LEFT JOIN ps_product_lang P ON C.id_product WHERE id_category = ?

PS. I see 12:37 am maybe you need to sleep

Mar:

Code: Select all  Expand view

oRsvolgorde:= oCn:RowSet( "SELECT * FROM, P.description_short as PName from ps_category_product C LEFT JOIN ps_product_lang P on C.id_product where id_category = ? " )
 

I can see the other side in ON clause

Code: Select all  Expand view

 Rsvolgorde:= oCn:RowSet( "SELECT * FROM, P.description_short as PName from ps_category_product C LEFT JOIN ps_product_lang P on C.id_product = ??????  where id_category = ? " )
 

Pls, look at the blue questions mark

Hello,
There is still a comma after the FROM that I am not sure is valid. But the query

Code: Select all  Expand view

SELECT * FROM Table1,Table2

is valid, then maybe the comma does not influence your query...

I think the correct query for you is:

Code: Select all  Expand view

SELECT P.description_short AS PName FROM ps_category_product C LEFT JOIN ps_product_lang P ON C.id_product = P.id_product WHERE id_category = ?

or is

Code: Select all  Expand view

SELECT C.*,P.description_short AS PName FROM ps_category_product C LEFT JOIN ps_product_lang P ON C.id_product = P.id_product WHERE id_category = ?

The sample Maria02 and 05 works and is showing 2 tables linked togetter, so that the xbrowse is showing 2 table informations

In the sample Xbrowser is used as function, not as command Xbrowse.

Do you have a sample where xbrowse is used not as function ?
