RDSDataService / Client / execute_statement

execute_statement#

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.

      • 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].

        • 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.

  • transactionId (string) –

    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.

  • includeResultMetadata (boolean) – A value that indicates whether to include metadata in the results.

  • continueAfterTimeout (boolean) –

    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.

  • resultSetOptions (dict) –

    Options that control how the result set is returned.

    • decimalReturnType (string) –

      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.

    • longReturnType (string) –

      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.

  • formatRecordsAs (string) –

    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.
