Load field

Anonymous — Fri, 09 Mar 2018 15:04:24 GMT

Hi all,

I'm trying to load a field if it contains certain information.

I know wildmatch loads values that contain certain information but I'm wondering if there is a way of loading a field if it contains certain information.

For example something like

Load

From Data Source

Where wildmatch(*,'Discuss Quote')

This would then load any fields that contain the words 'Discuss Quote' in it's row.

I will then do a crosstable to group these fields together into one field.

Thanks

Gareth

Why not do a crosstable and then check if the field contains Discuss Quote?

Good idea Sunny thanks but what would I use as my where clause?

Re: Load field

Something like this

Table:

CrossTable (Header, Value)

LOAD ....,

....

FROM ...;

FinalTable:

LOAD ...

Resident Table

Where WildMatch(Header, '*Discuss Quote*');

If I understand your question correctly, I think you would need a number of OR statements on the WHERE to check each field in turn for the content you are looking for.

I would agree with stalwar1‌ that doing the CrossTable first and then doing a WHERE on a RESIDENT load of that table may make more sense.

I can't because I don't know what the header is called.

Header 1 Header 2 Header 3

Discuss Quote Discuss Query Stop Payment

Discuss Problem Discuss Quote Hold Payment

So I would only want to crosstable Header 1 and Header 2

I've got loads of fields with very poorly laid out data.

So instead of loading each field in separately and doing a crosstable I was wondering if Qlikview could check if a field contains a string load that field if it doesn't then don't load the field.

Are you looking to get this?

Table:

CrossTable(Header, Value)

LOAD 1 as Temp,

LOAD * INLINE [

Header 1, Header 2, Header 3

Discuss Quote, Discuss Query, Stop Payment

Discuss Problem, Discuss Quote, Hold Payment

];

Right Join (Table)

LOAD Distinct Header

Resident Table

Where WildMatch(Value, '*Discuss Quote*');

When you say the "field contains a string" do you mean the field name, or the contents of that field in any row?

You could do a bit of code that loads the field list for the table and then loads distinct for each column with the where statement to then get the NoOfRows for that temporary table, and then build out the load script (list of fields) into a variable.

This feels like it would be far less efficient than having the AND statements on the WHERE.

If the issue is that you don't know what the fields are then there are ways of approaching this, which will differ depending on the data source.

please post some sample data and your expected result to clarify.

Thanks Steve,

I mean the contents of that field. So if the contents of any field contains 'Discuss Quote' load this. I can then add these fields that meet this criteria into a crosstable to lump them all into one field.

I hope I'm making sense!

Thanks

Hi Gareth,

stalwar1‌ 's solution above is spot on. It makes far more sense to do the cross table first and then exclude the rows. You don't need to know the column headers as you can load with *, so:

// Load all data into crosstable

tmpTable:

CROSSTABLE(Header,Value,1)

LOAD

1 as DummyField, // not sure if you can omit this and have ,0 on the CROSSTABLE statement

FROM [your data source]

;

// Get list of headers you are interested in

tmpHeaders:

LOAD DISTINCT

Header as ExistsHeader

WHERE WildMatch(Value, '*Discuss Quote*');

// Load all the data in any column which you are interested in

Table:

NOCONCATENATE LOAD

Header,

Value

WHERE EXISTS (ExistsHeader, Header)

;

// Clean up

DROP TABLE tmpTable;

DROP TABLE tmpHeaders;

Hope that helps.

Steve

Thanks for all your suggestions guys, I managed to build something that is very similar to stevedark‌ suggestion. So I'm basically creating a new field (Transactions) then only loading data that contains discuss quote/amend policy etc and so long as I drop the original TempTransactions table it will only load the data I want.

See below

TempTransactions:

CrossTable(Temp1,Transactions)

Load

FROM

[\\dcn3pfsh104\home_1\CYDU\Desktop\Webchat\Webchat*.xlsx]

(ooxml, embedded labels, table is [Data])

;

DROP Field Temp1;

Transactions:

NoConcatenate Load

Resident TempTransactions

Where Transactions = 'Discuss Quote' or Transactions = 'Amend/Discuss Policy' or Transactions = 'Cancel Policy' or Transactions = 'Renew Policy' or Transactions = 'Ghost Chat' or Transactions = 'Transfer Chat';

DROP Table TempTransactions;

Thanks again everyone!
