OBIEE12c. Count of chosen elements in parameter

Question

Hi

I have dashboard with prompt.

In prompt i chosen some values and i send result to analysis.

I choisen values:

Now, in analysis i want get number of chosen values - 3.

How i can get this?

The number of chosen values i put in a special presentation variable - it string-variable, where values are divided by commas

I see only one solution to the problem: use the function "EVALUATE"

Namely, the following: create store procedure in database, where i split a string-parameter to elements, count it and return result to OBI.

Is there a better way to count the number of values in the prompt?

1+CHAR_LENGTH('10,12,14,16') - CHAR_LENGTH(REPLACE('10,12,14,16', ',', ''))

In this case, the solution is suitable for me. Thanks, Gianni Ceresa

Christian Berg,  thanks too

What Christian said is a clean way of doing things.

If for any reason you can't do that there are other options, EVALUATE and a stored procedure is a bit ... too much ....

If the separator of your values in the variable is a comma and your values are numbers (without the comma) you can easily do it by doing something like:

1+CHAR_LENGTH('10,12,14,16') - CHAR_LENGTH(REPLACE('10,12,14,16', ',', ''))

(I used a string instead of a presentation variable but same business ....)
