SQL script!

$(QVDatabaseTable_1):

LOAD * ;

SQL SELECT count(*) as NoOf_Rows

 

FROM $(DatabaseName).$(DatabaseUser).$(DatabaseTable_1)

$(INCREMENTAL_EXP);

Store $(QVDatabaseTable_1) into $(vQVDFileName_1)(qvd);

Drop Table $(QVDatabaseTable_1);

This just will not run... do anybody have an idea?

i have also tried just

SQL SELECT count(*)

also.


please let me know if I am doing anything wrong.


Thank you!!

With aggregation, you need to use Group by the statement.

Something like:

SELECT somecolumn,someothercolumn, COUNT(*)
  
FROM my_table
GROUP BY somecolumn,someothercolumn

Hi,

Check whether your variables are populating with expected values.

^^ I agree, Variables are most probably the issue. the rest look fine imo.

You can add some TRACE before the LOAD statement, something like

TRACE  QVDatabaseTable_1=$(QVDatabaseTable_1);

TRACE DatabaseName=$(DatabaseName);

.....

to check you vars

Also you can post the error you get

Are your problem with sql query? (SELECT count(*) as NoOf_Rows ... )

Please, post error,which you get, when document is reloading.

OUTER JOIN worked perfectly for me!! I have a followup question.

is it possible to make another column by adding or subtracting other two columns?

for example, let's say by Outer Joining I got three columns col1, col2, col3

Can I make col4 by col1 - col2?

Yes, you can do that in the preceeding load

Table1:

Load

*,

col1 - col2 as col4;

sql....;

if you have a table (Table) with a logical primary key (Id) with a join

left join (Table)

load

    Id,

    col1 - col2 as col4

resident Table;

or you can always do a resident load

NewTable:

Noconcatenate    

Load

    *,

    col1 - col2 as col4

resident Table;

drop table Table;
