Updating Arrays

Hi

 

I exploring the use of arrays.

 

So far I have created a table and inserted a row and updated the row with an array

Update library.compare

  set _base =

  '{2, 0.764149497122068, 4.8886}'

  where process_id = 2;

– successfully.

 

However when I attempt to update a specific element of the array

 

Update library.compare

set _base[2] =

'{2}'

where process_id = 2;

I get an error “invalid input syntax for type numeric: "{2}"”

Create table library.compare (

id serial UNIQUE,

process_id int4,

device_id int4,

_base decimal[]

);

Insert into library.compare (process_id)

values ('2');
