You can call the CreateAccount operation to create an account that is used to manage databases on an ApsaraDB RDS instance.

Before you call this operation, make sure that the following requirements are met:

  • The instance must be in the Running state.
  • The databases must be in the Running state.
  • The number of accounts that are created on the instance cannot exceed the maximum number of accounts that are allowed per instance.
  • This operation is supported only for instances that run MySQL, MariaDB, or SQL Server. However, this operation is not supported for instances that run SQL Server 2017 EE.
  • You can create only one privileged account for each instance. However, this does not apply if the instance runs PostgreSQL with standard or enhanced SSDs.
  • You can log on to the instance by using its privileged account. Then, you can create standard accounts by using SQL statements.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
