Runs one or more SQL statements, which can be data manipulation language (DML) or data definition language (DDL). Depending on the authorization method, use one of the following combinations of request parameters:
-
Secrets Manager - when connecting to a cluster, provide the
secret-arnof a secret stored in Secrets Manager which hasusernameandpassword. The specified secret contains credentials to connect to thedatabaseyou specify. When you are connecting to a cluster, you also supply the database name, If you provide a cluster identifier (dbClusterIdentifier), it must match the cluster identifier stored in the secret. When you are connecting to a serverless workgroup, you also supply the database name. -
Temporary credentials - when connecting to your data warehouse, choose one
of the following options:
-
When connecting to a serverless workgroup, specify the workgroup name and
database name. The database user name is derived from the IAM identity.
For example,
arn:iam::123456789012:user:foohas the database user nameIAM:foo. Also, permission to call theredshift-serverless:GetCredentialsoperation is required. -
When connecting to a cluster as an IAM identity, specify the cluster
identifier and the database name. The database user name is derived from
the IAM identity. For example,
arn:iam::123456789012:user:foohas the database user nameIAM:foo. Also, permission to call theredshift:GetClusterCredentialsWithIAMoperation is required. -
When connecting to a cluster as a database user, specify the cluster
identifier, the database name, and the database user name. Also,
permission to call the
redshift:GetClusterCredentialsoperation is required.
-
When connecting to a serverless workgroup, specify the workgroup name and
database name. The database user name is derived from the IAM identity.
For example,
May throw ActiveSessionsExceededException.
May throw ActiveStatementsExceededException.
May throw BatchExecuteStatementException.
May throw InternalServerException.
May throw ResourceNotFoundException.
May throw ValidationException.
Parameter sqls :
One or more SQL statements to run. The SQL statements run serially in the
order of the array. Subsequent SQL statements don't start until the
previous statement in the array completes. By default, the SQL statements
are run as a single transaction. If any SQL statement fails, all work is
rolled back. To change this behavior, see the ExecutionMode
parameter.
Parameter clientToken :
A unique, case-sensitive identifier that you provide to ensure the
idempotency of the request.
Parameter clusterIdentifier :
The cluster identifier. This parameter is required when connecting to a
cluster and authenticating using either Secrets Manager or temporary
credentials.
Parameter database :
The name of the database. This parameter is required when authenticating
using either Secrets Manager or temporary credentials.
Parameter dbUser :
The database user name. This parameter is required when connecting to a
cluster as a database user and authenticating using temporary credentials.
Parameter executionMode :
Determines how the SQL statements in the batch are run. If set to
TRANSACTION (the default), all SQL statements are run as a
single transaction and they are committed or rolled back together. If set
to AUTO_COMMIT, each SQL statement is committed individually,
and a failure of one statement does not affect the others.
Parameter parameters :
The parameters for the SQL statements. The parameters are available to all
SQL statements in the batch. Each statement can reference any subset of
the provided parameters. Each provided parameter must be referenced by at
least one SQL statement in the batch.
Parameter resultFormat :
The data format of the result of the SQL statement. If no format is
specified, the default is JSON.
Parameter secretArn :
The name or ARN of the secret that enables access to the database. This
parameter is required when authenticating using Secrets Manager.
Parameter sessionId :
The session identifier of the query.
Parameter sessionKeepAliveSeconds :
The number of seconds to keep the session alive after the query finishes.
The maximum time a session can keep alive is 24 hours. After 24 hours, the
session is forced closed and the query is terminated.
Parameter statementName :
The name of the SQL statements. You can name the SQL statements when you
create them to identify the query.
Parameter waitTimeSeconds :
The number of seconds to wait for all SQL statements in the batch to
complete execution before returning the response. If the SQL statements do
not complete within the specified time, the response returns the current
status. The maximum value is 30 seconds.
Parameter withEvent :
A value that indicates whether to send an event to the Amazon EventBridge
event bus after the SQL statements run.
Parameter workgroupName :
The serverless workgroup name or Amazon Resource Name (ARN). This
parameter is required when connecting to a serverless workgroup and
authenticating using either Secrets Manager or temporary credentials.
