Client

class RDSDataService.Client

A low-level client representing AWS RDS DataService

Amazon RDS provides an HTTP endpoint to run SQL statements on an Amazon Aurora Serverless DB cluster. To run these statements, you work with the Data Service API.

For more information about the Data Service API, see Using the Data API in the Amazon Aurora User Guide .

import boto3

client = boto3.client('rds-data')

These are the available methods:

batch_execute_statement(**kwargs)

Runs a batch SQL statement over an array of data.

You can run bulk update and insert operations for multiple records using a DML statement with different parameter sets. Bulk operations can provide a significant performance improvement over individual insert and update operations.

Warning

If a call isn't part of a transaction because it doesn't include the transactionID parameter, changes that result from the call are committed automatically.

Parameters
  • database (string) -- The name of the database.
  • parameterSets (list) --

    The parameter set for the batch operation.

    The SQL statement is executed as many times as the number of parameter sets provided. To execute a SQL statement with no parameters, use one of the following options:

    • Specify one or more empty parameter sets.
    • Use the ExecuteStatement operation instead of the BatchExecuteStatement operation.

    Note

    Array parameters are not supported.

    • (list) --
      • (dict) --

        A parameter used in a SQL statement.

        • name (string) --

          The name of the parameter.

        • typeHint (string) --

          A hint that specifies the correct object type for data type mapping. Possible values are as follows:

          • DATE - The corresponding String parameter value is sent as an object of DATE type to the database. The accepted format is YYYY-MM-DD .
          • DECIMAL - The corresponding String parameter value is sent as an object of DECIMAL type to the database.
          • JSON - The corresponding String parameter value is sent as an object of JSON type to the database.
          • TIME - The corresponding String parameter value is sent as an object of TIME type to the database. The accepted format is HH:MM:SS[.FFF] .

begin_transaction(**kwargs)

Starts a SQL transaction.

<important> <p>A transaction can run for a maximum of 24 hours. A transaction is terminated and rolled back automatically after 24 hours.</p> <p>A transaction times out if no calls use its transaction ID in three minutes. If a transaction times out before it's committed, it's rolled back automatically.</p> <p>DDL statements inside a transaction cause an implicit commit. We recommend that you run each DDL statement in a separate <code>ExecuteStatement</code> call with <code>continueAfterTimeout</code> enabled.</p> </important>

The value of DOUBLE_OR_LONG specifies that it is converted to a Long value if its scale is 0, or to a Double value otherwise.

      Warning

      Conversion to Double or Long can result in roundoff errors due to precision loss. We recommend converting to String, especially when working with currency values.

          This is a Tagged Union structure. Only one of the following top level keys will be set: arrayValue, blobValue, booleanValue, doubleValue, isNull, longValue, stringValue. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

          'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

get_paginator(operation_name)

Create a paginator for an operation.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.
get_waiter(waiter_name)

Returns an object that can wait for some condition.

Parameters
waiter_name (str) -- The name of the waiter to get. See the waiters section of the service docs for a list of available waiters.
Returns
The specified waiter object.
Return type
botocore.waiter.Waiter
rollback_transaction(**kwargs)

Performs a rollback of a transaction. Rolling back a transaction cancels its changes.
