CloudTable.CreateIfNotExists 方法

定义

重载

CreateIfNotExists(TableRequestOptions, OperationContext, String, Nullable<Int32>, Nullable<Int32>)

如果表不存在,则创建表。

CreateIfNotExists(IndexingMode, Nullable<Int32>, Nullable<Int32>)

如果表不存在,则创建表。

CreateIfNotExists(TableRequestOptions, OperationContext, Nullable<IndexingMode>, Nullable<Int32>)
CreateIfNotExists(TableRequestOptions, OperationContext)
CreateIfNotExists()
CreateIfNotExists(Nullable<IndexingMode>, Nullable<Int32>)

CreateIfNotExists(TableRequestOptions, OperationContext, String, Nullable<Int32>, Nullable<Int32>)

如果表不存在,则创建表。

public virtual bool CreateIfNotExists (Microsoft.Azure.Cosmos.Table.TableRequestOptions requestOptions = default, Microsoft.Azure.Cosmos.Table.OperationContext operationContext = default, string serializedIndexingPolicy = default, int? throughput = default, int? defaultTimeToLive = default);
abstract member CreateIfNotExists : Microsoft.Azure.Cosmos.Table.TableRequestOptions * Microsoft.Azure.Cosmos.Table.OperationContext * string * Nullable<int> * Nullable<int> -> bool
override this.CreateIfNotExists : Microsoft.Azure.Cosmos.Table.TableRequestOptions * Microsoft.Azure.Cosmos.Table.OperationContext * string * Nullable<int> * Nullable<int> -> bool
Public Overridable Function CreateIfNotExists (Optional requestOptions As TableRequestOptions = Nothing, Optional operationContext As OperationContext = Nothing, Optional serializedIndexingPolicy As String = Nothing, Optional throughput As Nullable(Of Integer) = Nothing, Optional defaultTimeToLive As Nullable(Of Integer) = Nothing) As Boolean

参数

requestOptions
TableRequestOptions

一个 TableRequestOptions 对象,它指定请求的其他选项。

operationContext
OperationContext

一个 OperationContext 对象,它一个表示当前操作的上下文。

serializedIndexingPolicy
String

CosmosDB 表索引策略。

throughput
Nullable<Int32>

CosmosDB 表吞吐量。

defaultTimeToLive
Nullable<Int32>

CosmosDB 表生存时间(以秒为单位)。 Null 表示 TTL 处于关闭状态,-1 等于 TTL 处于打开状态并无限期保留行,任何其他值设置 TTL。

返回

如果表已创建,则为 true;否则为 false

注解

此 API 执行存在检查,因此需要列表权限。
