使用基于 vCore 的购买模型的单一数据库的资源限制Resource limits for single databases using the vCore-based purchasing model

本文提供针对使用基于 vCore 的购买模型的 Azure SQL 数据库的单一数据库的详细资源限制。This article provides the detailed resource limits for Azure SQL Database single databases using the vCore-based purchasing model.

有关 SQL 数据库服务器上单一数据库基于 DTU 的购买模型限制,请参阅 SQL 数据库服务器上的资源限制概述For DTU-based purchasing model limits for single databases on a SQL Database server, see Overview of resource limits on a SQL Database server.

重要

在某些情况下,可能需要收缩数据库来回收未使用的空间。Under some circumstances, you may need to shrink a database to reclaim unused space. 有关详细信息,请参阅管理 Azure SQL 数据库中的文件空间For more information, see Manage file space in Azure SQL Database.

可通过 Azure 门户Transact-SQLPowerShellAzure CLIREST API 为单一数据库设置服务层级、计算大小和存储量。You can set the service tier, compute size, and storage amount for a single database using the Azure portal, Transact-SQL, PowerShell, the Azure CLI, or the REST API.
