In my previous post I explained how can we fetch data from Azure Storage Table. Now I am going to explain how can we fetch filtered data:
Please visit previous post to start from scratch:
static void Main(string[] args)
{
int counter = 0;
StringBuilder sb = new StringBuilder();
//
Retrieve the storage account from the connection string.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("StorageConnectionString"));
//
Create the table client.
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
//
Create the CloudTable object that represents the "TableName1" table.
CloudTable table = tableClient.GetTableReference("TableName1");
//
Construct the query operation for all customer entities where
PartitionKey!="nitin".
string FilterCounterName = TableQuery.GenerateFilterCondition("ColumnName1", QueryComparisons.Equal, "nitin
dhiman");
string FilterTimeStamp = TableQuery.GenerateFilterConditionForDate("TIMESTAMP", QueryComparisons.GreaterThan,
DateTimeOffset.Now.AddDays(-1).Date);
string FinalFilter = TableQuery.CombineFilters(FilterCounterName, TableOperators.And,
FilterTimeStamp);
TableQuery<TableName1> query = new TableQuery<TableName1>().Where(FinalFilter);
// Print
the fields for each customer.
foreach (TableName1 entity in table.ExecuteQuery(query))
{
if (counter > 500) break;
counter++;
Console.WriteLine("{0}, {1},
{2}, {3}, {4}, {5}, {6}",
entity.PartitionKey,
entity.RowKey,
entity.CustomCloumn1,
entity.CustomCloumn2,
entity.CustomCloumn3,
entity.CustomCloumnN,
entity.TIMESTAMP);
sb.AppendFormat("{0}, {1}, {2}, {3}, {4}, {5}, {6}",
entity.PartitionKey,
entity.RowKey,
entity.CustomCloumn1,
entity.CustomCloumn2,
entity.CustomCloumn3,
entity.CustomCloumnN,
entity.TIMESTAMP);
}
Console.WriteLine(counter);
Console.WriteLine(sb.ToString());
Console.WriteLine("Done...
press a key to end.");
Console.ReadKey();
}
Congrats All Done. Run and check. Let me know if you face
any issue.
