lib: in variable

hi there,

can i store a connection string in a variable and then use in different load statements just the variable as a path ?

something like this ?:

let vPath='lib://LIBStandardData/';

LOAD

    *

FROM $(vPath)table.qvd

(qvd);

doesnt work. results in:

Cannot open file 'lib://LIBStandardData/table.qvd'

whereas the usage of the connection explicitely in the FROM clause does work...

any ideas ?

thanks,

philipp

Re: lib: in variable

Try with [] around, for me it works fine

let vPath='lib://LIBStandardData/';

LOAD

    *

FROM [$(vPath)table.qvd]

(qvd);

Re: lib: in variable

Hi Philipp - I was working on this exact scenario recently - try this - it works for me. It will give you example of the correct syntax to use when using variables - you need to wrap the variable in single quotes or brackets.

This will also give an idea on how to concatenate variables - for example the path and file name.

let vRootPath = 'lib://QlikSenseDataFolder/';

let vFileName = 'sample_data.qvd';

let vFullFilePath = '$(vRootPath)$(vFileName)';

trace This is the root path: $(vRootPath);

trace This is the file name: $(vFileName);

SampleTable:

Load * Inline [

id,department,budget,actual

1,Sales,200000, 250000

2,Human Resources,150000, 10000

3,Finance,300000,250000

4,IT,245000,100000

];

Store SampleTable INTO '$(vFullFilePath)' (qvd);

Re: lib: in variable

Hi Daniel,

What if the name of the file is the variable?

Can we use :

Load * from [lib://link/folder/fileName_$(variable).qvd](qvd) ?

I am actually trying load data dynamically, but it doesn't work the way I want to
