public final class TableServiceClient

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

Overview

The client encapsulates the URL for the Tables service endpoint and the credentials for accessing the storage or CosmosDB table API account. It provides methods to create, delete, and list tables within the account. These methods invoke REST API operations to make the requests and obtain the results that are returned.

Getting Started

The building and authenticating of instances of this client are handled by TableServiceClientBuilder instances. The following sample shows how to authenticate and build a TableServiceClient using a connection string.

TableServiceClient tableServiceClient = new TableServiceClientBuilder()
     .connectionString("connectionstring")
     .buildClient();

See TableServiceClientBuilder documentation for more information on constructing and authenticating a client.

The following samples show the various ways you can interact with the tables service using this client.

Create a Table

The createTable(String tableName) method can be used to create a new table within an Azure Storage or Azure Cosmos account. It returns a TableClient for the newly created table.

The following sample creates a table with the name "myTable".

TableClient tableClient = tableServiceClient.createTable("myTable");

 System.out.printf("Table with name '%s' was created.", tableClient.getTableName());

Note: for asynchronous sample, refer to TableServiceAsyncClient.

Delete a Table

The deleteTable(String tableName) method can be used to delete a table within an Azure Storage or Azure Cosmos account.

The following sample deletes the table with the name "myTable".

tableServiceClient.deleteTable("myTable");

 System.out.printf("Table with name '%s' was deleted.", "myTable");

Note: for asynchronous sample, refer to TableServiceAsyncClient.

Get a TableClient

The getTableClient(String tableName) method can be used to retrieve a TableClient for a table within an Azure Storage or Azure Cosmos account.

The following sample gets a TableClient for the table with the name "myTable".

TableClient tableClient = tableServiceClient.getTableClient("myTable");

 System.out.printf("Table with name '%s' was retrieved.", tableClient.getTableName());

Note: for asynchronous sample, refer to TableServiceAsyncClient.

List Tables

The listTables() method can be used to list all the tables in an Azure Storage or Azure Cosmos account.

The following samples lists the tables in the Tables service account.

Without filtering, returning all tables:

PagedIterable<TableItem> tableItems = tableServiceClient.listTables();

 tableItems.forEach(tableItem ->
     System.out.printf("Retrieved table with name '%s'.%n", tableItem.getName()));

With filtering:

ListTablesOptions options = new ListTablesOptions().setFilter("TableName eq 'myTable'");

 PagedIterable<TableItem> retrievedTableItems = tableServiceClient.listTables(options, Duration.ofSeconds(5),
     new Context("key1", "value1"));

 retrievedTableItems.forEach(tableItem ->
     System.out.printf("Retrieved table with name '%s'.%n", tableItem.getName()));

Note: for asynchronous sample, refer to TableServiceAsyncClient.

Get Table Properties

The getProperties() method can be used to get the properties of the account's Table service, including properties for Analytics and CORS (Cross-Origin Resource Sharing) rules. This operation is only supported on Azure Storage endpoints.

The following sample gets the properties of the Tables service account.

TableServiceProperties properties = tableServiceClient.getProperties();

 System.out.print("Retrieved service properties successfully.");

Note: for asynchronous sample, refer to TableServiceAsyncClient.

Set Table Properties

The setProperties(TableServiceProperties tableServiceProperties) method can be used to set the properties of the account's Table service, including properties for Analytics and CORS (Cross-Origin Resource Sharing) rules. This operation is only supported on Azure Storage endpoints.

The following sample sets the properties of the Tables service account.

TableServiceProperties properties = new TableServiceProperties()
     .setHourMetrics(new TableServiceMetrics()
         .setVersion("1.0")
         .setEnabled(true)
         .setIncludeApis(true)
         .setRetentionPolicy(new TableServiceRetentionPolicy()
             .setEnabled(true)
             .setDaysToRetain(5)))
     .setLogging(new TableServiceLogging()
         .setAnalyticsVersion("1.0")
         .setReadLogged(true)
         .setRetentionPolicy(new TableServiceRetentionPolicy()
             .setEnabled(true)
             .setDaysToRetain(5)));

 tableServiceClient.setProperties(properties);

 System.out.printf("Set service properties successfully.");

Note: for asynchronous sample, refer to TableServiceAsyncClient.

Get Table Statistics

The getStatistics() method can be used to retrieve statistics related to replication for the account's Table service. It is only available on the secondary location endpoint when read-access geo-redundant replication is enabled for the account. This operation is only supported on Azure Storage endpoints.

The following sample gets the statistics of the Tables service account.

TableServiceStatistics statistics = tableServiceClient.getStatistics();

 System.out.print("Retrieved service statistics successfully.");

Note: for asynchronous sample, refer to TableServiceAsyncClient.
