How to load multiple dynamic fields

marcel_olmo — Mon, 22 Oct 2018 21:41:33 GMT

Hi guys,

I have a table with dynamic structured data like this :

ID	Field1	Field2	Field3	Field4
1	2 rooms	1 bath
2	terrace	3 rooms	2 baths
3	garden	2 rooms	1 bath	terrace

And I'd like to have this desired result :

ID	Rooms	Baths	Terrace	Garden
1	2	1
2	3	2	1
3	2	1	1	1

How could I get that if the field1,field2, fieldN could be filled with any possible value which later will be my desired dimension?

Regards, Marcel.

Maybe using a crosstable load to get all informations into a single field, then separate numbers from text and map text type. Finally use a Generic load to create fields from type (if needed at all, you can do most analysis using the count & type field structure).

INPUT:

LOAD * INLINE [

ID Field1 Field2 Field3 Field4

1 2 rooms 1 bath

2 terrace 3 rooms 2 baths

3 garden 2 rooms 1 bath terrace

] (delimiter is '\t');

TMP:

CrossTable (Field, Value)

LOAD * Resident INPUT;

Generic

LOAD ID, Type, Count

WHERE Len(Trim(Type));

LOAD ID,

Value,

If(Len(Trim(Keepchar(Value,'0123456789'))),Keepchar(Value,'0123456789'),1) as Count,

Pick(WildMatch(lower(Value),'*garden*','*terrace*','*room*','*bath*'),'Garden','Terrace','Room','Bath') as Type

Resident TMP;

DROP TABLE TMP;

Thanks Stefan! It's just what I want. The only point I miss here is how can I join the desired final table from the generic load point.

For example ordering by namefield.

you can do it like Henric

The Generic Load

Thanks Stefan! I've just took the version of Rob, because It adds a wildmatch check for the name of the table to match.

Here's my final result fine :

ID	Room	Bath	Terrace	Garden
1	2	1
2	3	2	1
3	2	1	1	1

And the code to make it work :

GenericLabel :

Generic

LOAD ID, Type, Count

WHERE Len(Trim(Type));

LOAD ID,

Value,

If(Len(Trim(Keepchar(Value,'0123456789'))),Keepchar(Value,'0123456789'),1) as Count,

Pick(WildMatch(lower(Value),'*garden*','*terrace*','*room*','*bath*'),'Garden','Terrace','Room','Bath') as Type

Resident TMP;

CombinedGenericTable :

LOAD ID Resident TMP;

FOR i = NoOfTables()-1 to 0 STEP -1

LET vTable=TableName($(i));

IF WildMatch('$(vTable)', 'GenericLabel.*') THEN

LEFT JOIN ([CombinedGenericTable]) LOAD * RESIDENT [$(vTable)];

DROP TABLE [$(vTable)];

ENDIF

NEXT i

DROP TABLE TMP;
