RDSDataService.Client.
execute_statement
(**kwargs)¶Runs a SQL statement against a database.
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.
If the binary response data from the database is more than 1 MB, the call is terminated.

[REQUIRED]
The Amazon Resource Name (ARN) of the Aurora Serverless DB cluster.
[REQUIRED]
The ARN of the secret that enables access to the DB cluster. Enter the database user name and password for the credentials in the secret.
For information about creating the secret, see Create a database secret.
[REQUIRED]
The SQL statement to run.

Note
Currently, the schema
parameter isn't supported.
The parameters for the SQL statement.
Note
Array parameters are not supported.
A parameter used in a SQL statement.

The value of the parameter.
Note
This is a Tagged Union structure. Only one of the following top level keys can be set: isNull
, booleanValue
, longValue
, doubleValue
, stringValue
, blobValue
, arrayValue
.
A NULL value.
A value of Boolean data type.
A value of long data type.
A value of double data type.
A value of string data type.
A value of BLOB data type.
An array of values.
Note
This is a Tagged Union structure. Only one of the following top level keys can be set: booleanValues
, longValues
, doubleValues
, stringValues
, arrayValues
.
An array of Boolean values.
An array of integers.
An array of floating-point numbers.
An array of strings.
An array of arrays.
Contains an array.

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 .
