A Query is a specific request, given with particular syntax or key word in order to fetch the associated record/ item-row. Syntax must be as: [‘Attribute name’< operator > ’Search value’]. Amazon SimpleDB also supports SQL-like SELECT query. You can use operators like =, ! =, <, > <=, > =, STARTS-WITH, AND, OR, NOT, INTERSECTION AND UNION and the format of query should be [‘Attribute name’< operator > ’Search value’] For eg: [‘Name’ STARTS-WITH ‘T’] (It will return all the records in selected domain that contains name attribute with its value starts from ‘T’.) .
