getting the Query operation to work #5

Open georgedd opened 7 years ago

georgedd commented 7 years ago

I am using the aws-sdk-esp8266 successfully with a ESP 12F with both the "GetItem" & "PutItem" functions, BUT am struggling in getting the Query operation to work. Can anyone please help me.

The difficult section appears to be defining Key_Conditions and/or Conditions.

The following does NOT work:

queryInput.setTableName(TableName); queryInput.setIndexName(HASH_KEY_NAME);

// Condition Represents the selection criteria for a Query or Scan operation: For a Query operation, // Condition is used for specifying the KeyConditions to use when querying a table or an index. // For KeyConditions, only the following comparison operators are supported: EQ | LE | LT | GE | GT | // BEGINS_WITH | BETWEEN

Condition condition; condition.setComparisonOperator(EQ_COMPARISONOPERATOR); hashKey.setS(HASH_KEY_VALUE); AttributeValue AttrV1[] = { hashKey }; condition.setComparisonOperator(BETWEEN_COMPARISONOPERATOR); QueryOutput queryOutput = ddbClient.query(queryInput, actionError); ..

Please help me in getting the Query operation (using both the Primary partition key HASH_KEY_NAME / HASH_KEY_VALUE ("S") & Primary sort key RANGE_KEY_NAME / RANGE_KEY_VALUE ("N")) to work.

Best George.

Have you solved your problem?

Can you show your "GetItem" & "PutItem" functions?

Have you solved your problem?, If so, can you show your "Query" function... As there is no examples of using Query API, me also struggling, please help...
