TableClient Class

Reference

Package:: com.azure.data.tables

Maven Artifact:: com.azure:azure-data-tables:12.4.6

java.lang.Object
- com.azure.data.tables.TableClient

public final class TableClient

Provides a synchronous service client for accessing a table in the Azure Tables service.

Overview

The client encapsulates the URL for the table within the Tables service endpoint, the name of the table, and the credentials for accessing the storage or CosmosDB table API account. It provides synchronous methods to create and delete the table itself, as well as methods to create, upsert, update, delete, list, and get entities within the table. These methods invoke REST API operations to make the requests and obtain the results that are returned.

Getting Started

Authenticating and building instances of this client are handled by TableClientBuilder. This sample shows how to authenticate and build a TableClient instance using the TableClientBuilder and a connection string.

TableClient tableClient = new TableClientBuilder()
     .connectionString("connectionstring")
     .tableName("myTable")
     .buildClient();

For more information on building and authenticating, see the TableClientBuilder documentation.

The following code samples provide examples of common operations preformed with this client.

Create a TableEntity

The createEntity(TableEntity entity) method can be used to create a table entity within a table in your Azure Storage or Azure Cosmos account.

The sample below creates a TableEntity with a partition key of "partitionKey" and a row key of "rowKey".

TableEntity tableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 tableClient.createEntity(tableEntity);

 System.out.printf("Table entity with partition key '%s' and row key: '%s' was created.", "partitionKey", "rowKey");

Note: for asynchronous sample, refer to TableAsyncClient.

Retrieve a TableEntity

The getEntity(String partitionKey, String rowKey) method can be used to retrieve a table entity within a table in your Azure Storage or Azure Cosmos account.

The sample below retrieves a TableEntity with a partition key of "partitionKey" and a row key of "rowKey".

TableEntity tableEntity = tableClient.getEntity("partitionKey", "rowKey");

 System.out.printf("Retrieved entity with partition key '%s' and row key '%s'.", tableEntity.getPartitionKey(),
     tableEntity.getRowKey());

Note: for asynchronous sample, refer to TableAsyncClient.

Update a TableEntity

The updateEntity(TableEntity entity) method can be used to update a table entity within a table in your Azure Storage or Azure Cosmos account.

The sample below updates a TableEntity with a partition key of "partitionKey" and a row key of "rowKey", adding a new property with a key of "Property" and a value of "Value".

TableEntity myTableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 tableClient.updateEntity(myTableEntity, TableEntityUpdateMode.REPLACE);

 System.out.printf("Table entity with partition key '%s' and row key: '%s' was updated/created.", "partitionKey",
     "rowKey");

Note: for asynchronous sample, refer to TableAsyncClient.

List TableEntity

The listEntities() method can be used to list the entities within a table in your Azure Storage or Azure Cosmos account.

The following sample lists all TableEntity within the table without filtering out any entities.

PagedIterable<TableEntity> tableEntities = tableClient.listEntities();

 tableEntities.forEach(tableEntity ->
     System.out.printf("Retrieved entity with partition key '%s' and row key '%s'.%n",
         tableEntity.getPartitionKey(), tableEntity.getRowKey()));

List TableEntity with filtering and selecting

The following sample lists TableEntity within the table, filtering out any entities that do not have a partition key of "partitionKey" and a row key of "rowKey" and only selects the "name", "lastname", and "age" properties.

List<String> propertiesToSelect = new ArrayList<>();
 propertiesToSelect.add("name");
 propertiesToSelect.add("lastname");
 propertiesToSelect.add("age");

 ListEntitiesOptions listEntitiesOptions = new ListEntitiesOptions()
     .setTop(15)
     .setFilter("PartitionKey eq 'MyPartitionKey' and RowKey eq 'MyRowKey'")
     .setSelect(propertiesToSelect);

 PagedIterable<TableEntity> myTableEntities = tableClient.listEntities(listEntitiesOptions,
     Duration.ofSeconds(5), null);

 myTableEntities.forEach(tableEntity -> {
     System.out.printf("Retrieved entity with partition key '%s', row key '%s' and properties:%n",
         tableEntity.getPartitionKey(), tableEntity.getRowKey());

     tableEntity.getProperties().forEach((key, value) ->
         System.out.printf("Name: '%s'. Value: '%s'.%n", key, value));
 });

Note: for asynchronous sample, refer to TableAsyncClient.

Delete a TableEntity

The deleteEntity(String partitionKey, String rowKey) method can be used to delete a table entity within a table in your Azure Storage or Azure Cosmos account.

The sample below deletes a TableEntity with a partition key of "partitionKey" and a row key of "rowKey".

tableClient.deleteEntity("partitionKey", "rowKey");

 System.out.printf("Table entity with partition key '%s' and row key: '%s' was deleted.", "partitionKey", "rowKey");

Note: for asynchronous sample, refer to TableAsyncClient.

Submit a transactional batch

The submitTransaction(List<TableTransactionAction> transactionActions) method can be used to submit a transactional batch of actions to perform on the table in your Azure Storage or Azure Cosmos account.

The following sample shows how to prepare and submit a transactional batch with multiple actions.

List<TableTransactionAction> transactionActions = new ArrayList<>();

 String partitionKey = "markers";
 String firstEntityRowKey = "m001";
 String secondEntityRowKey = "m002";

 TableEntity firstEntity = new TableEntity(partitionKey, firstEntityRowKey)
     .addProperty("Type", "Dry")
     .addProperty("Color", "Red");

 transactionActions.add(new TableTransactionAction(TableTransactionActionType.CREATE, firstEntity));

 System.out.printf("Added create action for entity with partition key '%s', and row key '%s'.%n", partitionKey,
     firstEntityRowKey);

 TableEntity secondEntity = new TableEntity(partitionKey, secondEntityRowKey)
     .addProperty("Type", "Wet")
     .addProperty("Color", "Blue");

 transactionActions.add(new TableTransactionAction(TableTransactionActionType.CREATE, secondEntity));

 System.out.printf("Added create action for entity with partition key '%s', and row key '%s'.%n", partitionKey,
     secondEntityRowKey);

 TableTransactionResult tableTransactionResult = tableClient.submitTransaction(transactionActions);

 System.out.print("Submitted transaction. The ordered response status codes for the actions are:");

 tableTransactionResult.getTransactionActionResponses().forEach(tableTransactionActionResponse ->
     System.out.printf("%n%d", tableTransactionActionResponse.getStatusCode()));

Note: for asynchronous sample, refer to TableAsyncClient.

     .doOnError(TableTransactionFailedException.class, e -> {
         // If the transaction fails, the resulting exception contains the index of the first action that failed.
         int failedActionIndex = e.getFailedTransactionActionIndex();
         // You can use this index to modify the offending action or remove it from the list of actions to send
         // in the transaction, for example.
         transactionActions.remove(failedActionIndex);
         // And then retry submitting the transaction.
     })
     .subscribe(tableTransactionResult -> {
         System.out.print("Submitted transaction. The ordered response status codes for the actions are:");

Shows how to handle a transaction with a failing TableTransactionAction via the provided TableTransactionFailedException, which contains the index of the first failing action in the transaction.

try {
     Response<TableTransactionResult> transactionResultResponse =
         tableClient.submitTransactionWithResponse(myTransactionActions, Duration.ofSeconds(5),
             new Context("key1", "value1"));

     System.out.printf("Response successful with status code: %d. The ordered response status codes of the"

     transactionResultResponse.getValue().getTransactionActionResponses()
         .forEach(tableTransactionActionResponse ->
             System.out.printf("%n%d", tableTransactionActionResponse.getStatusCode()));
 } catch (TableTransactionFailedException e) {
     // If the transaction fails, the resulting exception contains the index of the first action that failed.
     int failedActionIndex = e.getFailedTransactionActionIndex();
     // You can use this index to modify the offending action or remove it from the list of actions to send in
     // the transaction, for example.
     myTransactionActions.remove(failedActionIndex);
     // And then retry submitting the transaction.
 }

Parameters:

transactionActions - A List of TableTransactionAction to perform on TableEntity in a table.

timeout - An optional timeout value beyond which a RuntimeException will be raised.

context - Additional Context that is passed through the HttpPipeline during the service call.

Returns:

An Response<T> produced for the transaction itself. The response's value will contain a List of TableTransactionActionResponse that correspond to each TableTransactionAction in the transaction.

updateEntity

public void updateEntity(TableEntity entity)

Updates an existing TableEntity by merging the provided TableEntity with the existing TableEntity.

Code Samples

Updates a TableEntity on the table. Prints out the details of the updated TableEntity.

TableEntity tableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 tableClient.updateEntity(tableEntity);

 System.out.printf("Table entity with partition key '%s' and row key: '%s' was updated/created.", "partitionKey",
     "rowKey");

Parameters:

entity - The TableEntity to update.

updateEntity

public void updateEntity(TableEntity entity, TableEntityUpdateMode updateMode)

Updates an existing TableEntity using the specified TableEntityUpdateMode. The default TableEntityUpdateMode is MERGE.

When the TableEntityUpdateMode is MERGE, the provided TableEntity's properties will be merged into the existing TableEntity. When the TableEntityUpdateMode is REPLACE, the provided TableEntity's properties will completely replace those in the existing TableEntity.

Code Samples

Updates a TableEntity on the table with the specified TableEntityUpdateMode. Prints out the details of the updated TableEntity.

TableEntity myTableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 tableClient.updateEntity(myTableEntity, TableEntityUpdateMode.REPLACE);

 System.out.printf("Table entity with partition key '%s' and row key: '%s' was updated/created.", "partitionKey",
     "rowKey");

Parameters:

entity - The TableEntity to update.

updateMode - The type of update to perform.

updateEntityWithResponse

public Response updateEntityWithResponse(TableEntity entity, TableEntityUpdateMode updateMode, boolean ifUnchanged, Duration timeout, Context context)

Updates an existing TableEntity using the specified TableEntityUpdateMode. The default TableEntityUpdateMode is MERGE.

Code Samples

Updates a TableEntity on the table with the specified update mode if the ETags on both TableEntity match. Prints out the details of the Response<T> updated TableEntity.

TableEntity someTableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 Response<Void> response = tableClient.updateEntityWithResponse(someTableEntity, TableEntityUpdateMode.REPLACE,
     true, Duration.ofSeconds(5), new Context("key1", "value1"));

 System.out.printf("Response successful with status code: %d. Table entity with partition key '%s' and row key"
     + " '%s' was updated.", response.getStatusCode(), "partitionKey", "rowKey");

Parameters:

entity - The TableEntity to update.

updateMode - The type of update to perform.

timeout - An optional timeout value beyond which a RuntimeException will be raised.

context - Additional Context that is passed through the HttpPipeline during the service call.

Returns:

The Response<T>.

upsertEntity

public void upsertEntity(TableEntity entity)

Inserts an TableEntity into the table if it does not exist, or merges the TableEntity with the existing TableEntity otherwise.

Code Samples

Upserts an TableEntity into the table. Prints out the details of the upserted TableEntity.

TableEntity tableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 tableClient.upsertEntity(tableEntity);

 System.out.printf("Table entity with partition key '%s' and row key: '%s' was updated/created.", "partitionKey",
     "rowKey");

Parameters:

entity - The TableEntity to upsert.

upsertEntityWithResponse

public Response upsertEntityWithResponse(TableEntity entity, TableEntityUpdateMode updateMode, Duration timeout, Context context)

Inserts an TableEntity into the table if it does not exist, or updates the existing TableEntity using the specified TableEntityUpdateMode otherwise. The default TableEntityUpdateMode is MERGE.

Code Samples

Upserts an TableEntity into the table with the specified TableEntityUpdateMode if said TableEntity already exists. Prints out the details of the Response<T> and the upserted TableEntity.

TableEntity myTableEntity = new TableEntity("partitionKey", "rowKey")
     .addProperty("Property", "Value");

 Response<Void> response = tableClient.upsertEntityWithResponse(myTableEntity, TableEntityUpdateMode.REPLACE,
     Duration.ofSeconds(5), new Context("key1", "value1"));

 System.out.printf("Response successful with status code: %d. Table entity with partition key '%s' and row key"
     + " '%s' was updated/created.", response.getStatusCode(), "partitionKey", "rowKey");

Parameters:

entity - The TableEntity to upsert.

updateMode - The type of update to perform if the TableEntity already exits.
