Only load relevant records (Exists?)

All,

I have the below script. The first part loads Email records. The second part loads interactions with those emails. So 1 email can have 100 interactions for example.

I only want to load interactions from existing email records. Otherwise the dataset would be to large. I tried the below script with an exists function but that doesn't work.

Any help to get this working would be appreciated!

Regards, Paul

TempEmailSend:
SQL SELECT
`cdi_campaignid_Name`,
    `cdi_fromname`,
    `cdi_openscount`,
    `cdi_senton`,
    `cdi_subject`,
    statuscode,
    `Id`
FROM .....`_emailsend`

EmailSend:
Load
`cdi_campaignid_Name`         as Campaign_Name,
    `cdi_fromname`                    as ES_From,
    `cdi_openscount`                  as ES_OpenCount,
    Date(`cdi_senton`)                as Datum,
    `cdi_subject`                         as ES_Subject,
    `Id`                                          as `cdi_emailsendid_Id`
Resident TempEmailSend
Where statuscode = 'Sent';


Drop Table TempEmailSend;

TempEE:
SQL SELECT
`cdi_emailsendid_Id`,
`cdi_type`                                as EE_Type,
`cdi_url`                                as EE_URL,
"cdi_time"                           as EE_Date    
FROM .....`_emailevent`
Where Exists (cdi_emailsendid_Id);

Hi Paul,

don't use "exists" in your SQL select. The Exists in SQL has different entry. Try this:

EmailSend:

LOAD *;


SQL SELECT
`cdi_campaignid_Name`,
    `cdi_fromname`,
    `cdi_openscount`,
    `cdi_senton`,
    `cdi_subject`,
    statuscode,
    `Id`
FROM .....`_emailsend`

WHERE statuscode = 'Sent';

TempEE:

LOAD *

WHERE Exists (Id,cdi_emailsendid_Id);


SQL SELECT
`cdi_emailsendid_Id`,
`cdi_type`                                as EE_Type,
`cdi_url`                                as EE_URL,
"cdi_time"                           as EE_Date    
FROM .....`_emailevent`;

Thanks.

try

WHERE EXISTS(Id, cdi_emailsendid_Id) ;

The first parameter should be a previously existing field, and the second a field or expression in the current load.

Nope got the following error:

Connector reply error: SQL##f - SqlState: 42000, ErrorCode: 4294967295, ErrorMsg: Malformed SQL Statement: Expected token 'FROM' but found 0 with value 'Id' instead at position 222.

try a presceding load like this:

TempEE:

Load cdi_emailsendid_Id,

EE_Type

EE_URL,

EE_Date

Where Exists (cdi_emailsendid_Id);

;

SQL SELECT

`cdi_emailsendid_Id`,

`cdi_type`                                as EE_Type,

`cdi_url`                                as EE_URL,

"cdi_time"                           as EE_Date    

FROM .....`_emailevent`

Great that worked!

Question; I hoped it would speed up my load process but it seems to cost even more time. Is there a way that I can make my load faster?

Hi zhadrakas,

on the EmailSend Table, the field Id is renamed as `cdi_emailsendid_Id`.. so he can't use the Id no more on the where exists

Hi Paul,

exists itself is quite memory consuming. In other hand you can put your Exists into SQL and leave the job to be done by DB, but I am not sure whether that would decrease reload time or not. Maybe use 64bit connector instead of 32bit (if you do not so and if it is possible), try to reduce number of fields to minimum...but this is more like general advice you are probably aware of...

Thanks.

what about combining the queries into one SQL:

somethink like this

TempEmailSend:

SQL SELECT

    SEND.`cdi_campaignid_Name` as Campaign_Name,

    SEND.`cdi_fromname` as ES_From,

    SEND. `cdi_openscount` as ES_OpenCount,

    SEND.`cdi_senton`, as Datum,

    SEND.`cdi_subject` as ES_Subject,

    SEND.statuscode ,

    SEND.`Id` as `cdi_emailsendid_Id`,

    EVENT.`cdi_type` as EE_Type,

    EVENT.`cdi_url` as EE_URL,

    EVENT.`cdi_time`  as EE_Date   

FROM `_emailsend` SEND,   

     `_emailevent` EVENT

Where SEND.statuscode = 'Sent'

  AND EVENT.`cdi_emailsendid_Id = SEND.`Id`
