Concat - script function

Concat() is used to combine string values. The script function returns the aggregated string concatenation of all values of the expression iterated over a number of records as defined by a group by clause.

Syntax:  

Concat ([ distinct ] string [, delimiter [, sort-weight]])

Return data type: string

Arguments:  

The expression or field containing the string to be processed.

Argument Description
string

The expression or field containing the string to be processed.

delimiter Each value may be separated by the string found in delimiter.
sort-weight

The order of concatenation may be determined by the value of the dimension sort-weight, if present, with the string corresponding to the lowest value appearing first in the concatenation.

distinct If the word distinct occurs before the expression, all duplicates are disregarded.

Examples and results:  

Add the example script to your app and run it. Then add, at least, the fields listed in the results column to a sheet in your app to see the result.

Given that the TeamData table is loaded as in the previous example:

LOAD SalesGroup,Concat(distinct Team,'-') as TeamConcat2 Resident TeamData Group By SalesGroup;

Epsilon-Eta-Theta-Zeta

Given that the TeamData table is loaded as in the previous example:

LOAD SalesGroup,Concat(distinct Team,'-',Amount) as TeamConcat2 Resident TeamData Group By SalesGroup;

Because the argument for sort-weight is added, the results are ordered by the value of the dimension Amount.
