I don’t understand the the query parameter
In the session the query data as the below
aws dynamodb query \
–table-name Medicines \
–select SPECIFIC_ATTRIBUTES \
–projection-expression “AvailableBrands” \
where is the SPECIFIC_ATTRIBUTES is from and what does --projection-expression means ?
Hi Prem!
We use the SPECIFIC_ATTRIBUTES keyword to specify the property that we don’t want to get all the data from the table but the specific one and --projection-expression keyword to specify the name of that attribute.
Hope it will clear your confusion. If you still have any queries please let us know.
Thank you.
