Package:
com.microsoft.azure.functions.annotation
Maven Artifact:
com.microsoft.azure.functions:azure-functions-java-library:1.3.1

Implements

java.lang.annotation.Annotation

public interface TableInput
implements java.lang.annotation.Annotation

Place this on a parameter whose value would come from storage table. The parameter type can be one of the following:

  • Any native Java types such as int, String, byte[]
  • Nullable values using Optional<T>
  • Any POJO type

The following example shows an HTTP trigger which returned the total count of the items in a table storage:

@FunctionName("getallcount")
 public int run(
    @HttpTrigger(name = "req",
                  methods = {"get"},
                  authLevel = AuthorizationLevel.ANONYMOUS) Object dummyShouldNotBeUsed,
    @TableInput(name = "items",
                 tableName = "mytablename",
                 partitionKey = "myparkey",
                 connection = "myconnvarname") MyItem[] items
 ) {
     return items.length;
 }

partitionKey

public abstract String partitionKey()

Defines the partition key of the storage table to which to bind.

Returns:

The storage table partition key string.

rowKey

public abstract String rowKey()

Defines the row key of the storage table to which to bind.

Returns:

The storage table row key string.
