Oracle equivalent of Java's Varargs
(2 answers)
Closed 3 years ago.
Can a function in Oracle have an unknown number of parameters?
for example: create function sample(parameters... varchar)
so it can call something like: sample("A") or sample("A","B") or sample("A","B","C")
You can use sys.odcivarchar2list:
function sample(parameters sys.odcivarchar2list)
And then call it by:
sample(sys.odcivarchar2list('A','B','C'))
or
sample(sys.odcivarchar2list('A'))
and so on.

I have a series of datetime variables that need to be referenced, and the key to which variable needs referencing is reached by using substring on another field. I can create the name of the variable as a string using string manipulation, something like this:
'#' + SUBSTRING(field, CHARINDEX(',', field) + 2, LEN(field) - CHARINDEX(',', field) + 1) + 'start'
Is there a way to get SQL to recognize that this is the name of one of my variables? Some kind of function to convert the string?

Like
The LIKE operator is used to search for a specified pattern in a column.
Where
The WHERE clause is used to extract only those records that fulfill a specified criterion.
In your case the first query do not work is because no records match the criteria you are searching.
