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 v1 DB cluster. To run these statements, you work with the Data Service API.
Note
The Data Service API isn't supported on Amazon Aurora Serverless v2 DB clusters.
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()begin_transaction()can_paginate()close()commit_transaction()execute_sql()execute_statement()get_paginator()get_waiter()rollback_transaction()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.
Note
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.
There isn't a fixed upper limit on the number of parameter sets. However, the maximum size of the HTTP request submitted through the Data API is 4 MiB. If the request exceeds this limit, the Data API returns an error and doesn't process the request. This 4-MiB limit includes the size of the HTTP headers and the JSON notation in the request. Thus, the number of parameter sets that you can include depends on a combination of factors, such as the size of the SQL statement and the size of each parameter set.
The response size limit is 1 MiB. If the call returns more than 1 MiB of response data, the call is terminated.

Specify the transaction ID of the transaction that you want to include the SQL statement in.
If the SQL statement is not part of a transaction, don't set this parameter.

Note
A transaction can run for a maximum of 24 hours. A transaction is terminated and rolled back automatically after 24 hours.
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.
DDL statements inside a transaction cause an implicit commit. We recommend that you run each DDL statement in a separate ExecuteStatement call with continueAfterTimeout enabled.

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] .TIMESTAMP - The corresponding String parameter value is sent as an object of TIMESTAMP type to the database. The accepted format is YYYY-MM-DD HH:MM:SS[.FFF] .UUID - The corresponding String parameter value is sent as an object of UUID type to the database.The identifier of a transaction that was started by using the BeginTransaction operation. Specify the transaction ID of the transaction that you want to include the SQL statement in.
If the SQL statement is not part of a transaction, don't set this parameter.
A value that indicates whether to continue running the statement after the call times out. By default, the statement stops running when the call times out.
Note
For DDL statements, we recommend continuing to run the statement after the call times out. When a DDL statement terminates before it is finished running, it can result in errors and possibly corrupted data structures.
Options that control how the result set is returned.
A value that indicates how a field of DECIMAL type is represented in the response. The value of STRING , the default, specifies that it is converted to a String value. 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.
Note
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.
A value that indicates how a field of LONG type is represented. Allowed values are LONG and STRING . The default is LONG . Specify STRING if the length or precision of numeric values might cause truncation or rounding errors.
A value that indicates whether to format the result set as a single JSON string. This parameter only applies to SELECT statements and is ignored for other types of statements. Allowed values are NONE and JSON . The default value is NONE . The result is returned in the formattedRecords field.
For usage information about the JSON format for result sets, see Using the Data API in the Amazon Aurora User Guide .

'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}
booleanValues (list) --
An array of Boolean values.
longValues (list) --
An array of integers.
doubleValues (list) --
An array of floating-point numbers.
stringValues (list) --
An array of strings.
arrayValues (list) --
An array of arrays.
(dict) --
Contains an array.
