// Runs an SQL statement, which can be data manipulation language (DML) or data
// definition language (DDL). This statement must be a single SQL statement.
// Depending on the authorization method, use one of the following combinations of
// request parameters:
//   - Secrets Manager - when connecting to a cluster, provide the secret-arn of a
//     secret stored in Secrets Manager which has username and password . The
//     specified secret contains credentials to connect to the database you 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:foo has the database user name IAM:foo .
//     Also, permission to call the redshift-serverless:GetCredentials operation 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:foo has the database user
//     name IAM:foo . Also, permission to call the
//     redshift:GetClusterCredentialsWithIAM operation 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:GetClusterCredentials operation is required.
