And if you want to stick to the Match() function:

Test:

Load * Inline [

ID,  Net

1, 200

2, 300

3, 400

4, 500 ];

//****Assuming below  ID data is coming from external file and they keep changing****

Check:

LOAD Concat( chr(39) & ID & chr(39), ',') as Check;

Load ID inline [

ID

1,

3];

Let vCheck = Peek('Check',0);

DROP TABLE Check;

Result:

NoConcatenate

Load *

Resident Test

where match(ID,$(vCheck));

drop table Test;

It might be easier to use the Exists() function to check against your field loaded from Excel:

Test:

Load * Inline [

ID,  Net

1, 200

2, 300

3, 400

4, 500 ];

//****Assuming below  ID data is coming from external file and they keep changing****

Load ID as IDCheck inline [

ID

1,

3];

NoConcatenate

Load *

Resident Test

where Exists(IDCheck, ID); //match(ID,'1','3');

drop table Test;  // instead of harcoding ID values 1 and 3 is there any way get them inside match function using varibale?? like mentioned above ID's will be maintined in external file and will be chnaging and we cant hardcode them everyday

DROP FIELD IDCheck;

Alternatively if you load the ID to check first:

Load ID  inline [

ID

1,

3];

Test:

Load * Inline [

ID,  Net

1, 200

2, 300

3, 400

4, 500 ]

WHERE Exists(ID);

Hi @swuehl ,

I am getting that values, but want to use them in Match() in expression,

// monthCombo gives 'y','o','u'

=count(DISTINCT(if(match(status,monthCombo),sale)))

But it is not working.

Please help.

 

Regards.

What about

 

=count(DISTINCT if( status = monthCombo,sale))

 

?

Used this one and worked fine,
=count(DISTINCT(if(WildMatch(status,'*$(monthCombo)*'),sale)))
Thanks.
