Joining tables in powerapps

[asafweis]

Hi,

I'm trying to join tables together as in the SQL querie below, but can't get my head around the sytax in powerapps.

ShipmentLines Left Outer Join Jobs on smljobid = jmpjobid Left Outer Join MfgReceipts on rmmJobID = JMPJOBID

Any help would be really appreciated.

You can find an example of how to join two Power Apps collections at the link below.  It does the same thing as a SQL LEFT JOIN.

Hi @asafweis ,

Do you want to combine three tables into one in Power Apps app?

If you do, you may use the collection by two steps for easy understanding:

Step 1: Join MfgReceipts to Jobs with below formula:

ClearCollect(
             NewTable,
             Ungroup(
                     AddColumns(
                                Jobs,
                                "GroupColumn1",
                                Filter(
                                       MfgReceipts,
                                       rmmjobid=jmpjobid
                                )
                     ),
                     "GroupColumn1"
             )
)

Step 2: Join the collection to ShipmentLines and drop the columns of ids:

ClearCollect(NewTable2,
             DropColumns(
                         Ungroup(
                                 DropColumns(
                                             AddColumns(
                                                        shipmentlines,
                                                        "GroupColumn2",
                                                        Filter(
                                                               NewTable,
                                                               jmpjobid=smljobid
                                                        )
                                             ),
                                             "smljobid"
                                 ),
                                 "GroupColumn2"
                         ),
                         "rmmjobid",
                         "jmpjobid"
             )
)
