Table not found Left Join ([Flight Data]) error after modifying a script in QV for Devs 11 p. 435

[happyjoshua777]

Hello,

I tried removing an INNER JOIN in the following script:

[Carrier Decode]:

IntervalMatch (Date, [%Unique Carrier Entity Code])

LOAD

[Start Date],

      If(Len([End Date]) < 1, Today(1), [End Date]) as [End Date],

      [Unique Carrier Entity] as [%Unique Carrier Entity Code],

FROM

[..\3.QVD\Source\Carrier Decode.qvd]

(qvd);

Inner Join ([Carrier Decode])

LOAD

[Start Date],

     If(Len([End Date]) < 1, Today(1), [End Date]) as [End Date],

     [Unique Carrier Entity] as [%Unique Carrier Entity Code],

     [Carrier Group ID] as [%Carrier Group ID]

FROM

[..\3.QVD\Source\Carrier Decode.qvd]

(qvd);

Left Join ([Flight Data])

Load

Date,

[%Unique Carrier Entity Code],

[%Carrier Group ID]

Resident [Carrier Decode];

Drop Table [Carrier Decode];

Drop Field Date;

Store [Flight Data] into [..\3.QVD\Transformed\'Transformed - Flight Data.qvd'];

Drop Table [Flight Data];

as follows:

[Carrier Decode]:

IntervalMatch (Date, [%Unique Carrier Entity Code])

LOAD

[Start Date],

      If(Len([End Date]) < 1, Today(1), [End Date]) as [End Date],

      [Unique Carrier Entity] as [%Unique Carrier Entity Code],

           [Carrier Group ID] as [%Carrier Group ID] //inserted this line

FROM

[..\3.QVD\Source\Carrier Decode.qvd]

(qvd);

/*Inner Join ([Carrier Decode])

LOAD

...

[..\3.QVD\Source\Carrier Decode.qvd]

(qvd);

*/

Left Join ([Flight Data])

Load

Date,

[%Unique Carrier Entity Code],

[%Carrier Group ID]

Resident [Carrier Decode];

Drop Table [Carrier Decode];

Drop Field Date;

Store [Flight Data] into [..\3.QVD\Transformed\'Transformed - Flight Data.qvd'];

Drop Table [Flight Data];

now I am  getting the following error:

Table not found

Left Join ([Flight Data])

                Load

                                 Date,

                                 [%Unique Carrier Entity Code],

                                 [%Carrier Group ID]

                Resident [Carrier Decode]

I do not understand how bypassing an INNER JOIN command has removed access to the Flight Date table in the Facts data tab (see below)?

thanks

Do you have Flight Data table with you?

Not sure, Which pattern is first and which is next and next-next. So, Can you help us to make it clear in      QVS for full script? So, then we may dispense better

[happyjoshua777]

     [Flight Data]:

     ...

is traversed first (happens to be the Fact table in this case)

then

     [Carrier Decode]:

     IntervalMatch (Date, [%Unique Carrier Entity Code])

     LOAD

     [Start Date],

...

code is traversed in the next sheet.

thanks

True, When we do in script with Left Join () it should be places to the left part of the script. So, You cannot with Right join and using Left join to the Fact table.

PFA of your script and sample QVW attached with same schema
