How to realize SQL's function TO_NVARCHAR with Column Engine's functions?

Former Member — Tue, 14 Feb 2017 08:43:04 GMT

In HANA STUDIO, I used SQL function TO_NVARCHAR(''BLDAT'','YYYY/MM/DD') in Calculated Columns to convert the YYYYMMDD date in BLDAT into YYYY/MM/DD and made it.

But according to project's request, this conversion should be realized with Column Engine, not SQL. Please answer this question, if you have some good ideas, Thank u so much.

You can use a combination of the DATE and FORMAT function. The DATE function to convert the BLDAT date string to a date which then can be used by the FORMAT function to create a NVARCHAR typed result in your format.

The expression for the column engine calculated column looks like following:

format(date("BLDAT"),'YYYY/MM/DD')
