Could you please explain a bit more? List out the seperate steps you are taking(planning on taking) to accomplish this.
Do you intend to retreive something from mongoldb and the result will have an array that you want to update an occurrence of that array then update the database with that result
OR do you want to send a value that, in an update statement, you want to change a particular occurance of a column in the database? How will you know what occurance to change?
(NOTE: not being a mongodb user, the 'terms' misght be incorrect - forgive me for that)
