Querying Windows Azure Table Storage with multiple query criteria

Question

I\'m trying to query a table in Windows Azure storage and was initially using the TableQuery.CombineFilters in the TableQuery().Where<

Answer 1

This is what I am using as a quick check for the range of uploaded records.

        .....

        Dictionary retrievedRecords = new Dictionary();
        int i = 0;

        StorageCredentials creds = new StorageCredentials(accountName, accountKey); // table storage name, Azure provided KEY1 string
        CloudStorageAccount storageAccount = new CloudStorageAccount(creds, useHttps: true);
        CloudTableClient tableClient = storageAccount.CreateCloudTableClient();

        CloudTable table = tableClient.GetTableReference(tableName); // your table name

        // filters
        string filter1 = TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, partitionName); // partitionName i.e.: "myTablePartition1"
        string filter2 = TableQuery.GenerateFilterCondition("RowKey", QueryComparisons.GreaterThanOrEqual, recordStart); // recordStart i.e.: "123"
        string filter3 = TableQuery.GenerateFilterCondition("RowKey", QueryComparisons.LessThan, recordEnd); // recordEnd i.e.: "567"

        string filterRange = TableQuery.CombineFilters(filter2, TableOperators.And, filter3);


        // query.
        TableQuery rangeQuery = new TableQuery().Where(

            TableQuery.CombineFilters(filter1, TableOperators.And, filterRange)
        );

        // Loop & store
        foreach (CustomerEntity entityT in table.ExecuteQuery(rangeQuery))
        {
            string PartitionKey = entityT.PartitionKey;
            string RowKey = entityT.RowKey;
            string col1 = entityT.col1;
            string col2  = entityT.col2;
            string col3  = entityT.col3;
            string col4  = entityT.col4;
            string col5  = entityT.col5;
            string col6  = entityT.col6;

            string[] row = new string[] { PartitionKey, RowKey, col1 , col2, col3, col4, col5, col6 };
            retrievedRecords.Add(i, row);

            i++;
        }

        return retrievedRecords;

// function end or else.....
