batch-execute-statement

Description

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.

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.

Options

--database (string)

The name of the database.

--parameter-sets (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)

(structure)

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] .

• 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.

--resource-arn (string)

The Amazon Resource Name (ARN) of the Aurora Serverless DB cluster.

--schema (string)

The name of the database schema.

--secret-arn (string)

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 .

--sql (string)

The SQL statement to run. Don’t include a semicolon (;) at the end of the SQL statement.

--transaction-id (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.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To execute a batch SQL statement

The following batch-execute-statement example executes a batch SQL statement over an array of data with a parameter set.

aws rds-data batch-execute-statement \
    --resource-arn "arn:aws:rds:us-west-2:123456789012:cluster:mydbcluster" \
    --database "mydb" \
    --secret-arn "arn:aws:secretsmanager:us-west-2:123456789012:secret:mysecret" \
    --sql "insert into mytable values (:id, :val)" \
    --parameter-sets "[[{\"name\": \"id\", \"value\": {\"longValue\": 1}},{\"name\": \"val\", \"value\": {\"stringValue\": \"ValueOne\"}}],
        [{\"name\": \"id\", \"value\": {\"longValue\": 2}},{\"name\": \"val\", \"value\": {\"stringValue\": \"ValueTwo\"}}],
        [{\"name\": \"id\", \"value\": {\"longValue\": 3}},{\"name\": \"val\", \"value\": {\"stringValue\": \"ValueThree\"}}]]"

This command produces no output.
