Maria,
You mean your array has a variable size, which you need to know in order to properly construct a query?
Dunno much about arrays, but here http://www.postgresql.org/docs/8.3/static/arrays.html is said that array_upper( your_array, 1 ) returns the upper bound of the array...
Can this be what you need...?
Best,
Oliveiros

Subject: [SQL] Accessing array datatype
Hi All,
I have an array column in a table.
How can I fetch the elements separately( ie, select arr[1],arr[2]...arr[n]) as a column,
when I don't know how many elements are there in the array?
Thanks for your help.
Maria
