In my case I have a table name "friends" which has two attributes:
- account_id
- fb_id
I try to get all the account_id based on fb_id, and for this wrote the query as below:
$response = $dynamoClient->getItem ( array(
"TableName" => "facebook_friendlist",
"ConsistentRead" => true,
"Key" => array(
"fb_id" => array(
"S" => "171092723281123"//$fbId
)
),
"ProjectionExpression" => "account_id"
) );
But its not getting executed. I also tried to write the same query using getItem(),scan(),getIterator() but no result.
Help me out with the right way. Thanks in advance.
