Table storage triggers and bindings

Table storage input binding

Defining a binding between an Azure Function and a table in a storage account can be defined in two different ways.

The sample functions presented here do not include a trigger and do not work as-is.

Bindings can be declared through code in C# using the TableAttribute.

public static void Run([Table("Persons")]ICollector<Person> tableBinding, TraceWriter log)
{           
    tableBinding.Add(
        new Person() { 
            PartitionKey = "Default", 
            RowKey = 1, 
            Name = "Some name" }
        );
}

Bindings can also be declared through a configuration file. To do so, create a functions.json file and define your binding. This binding automatically adds the objects added to the ICollector to the defined table.

{
  "bindings": [
    {
      "type": "table",
      "name": "tableBindings",
      "tableName": "Person",
      "direction": "out"
    }
  ],
  "disabled": false
}

public static void Run(ICollector<Person> tableBinding, TraceWriter log)
{           
    tableBinding.Add(
        new Person() { 
            PartitionKey = "Default", 
            RowKey = 1, 
            Name = "Some name" }
        );
}
