 * @param {string} [parameters.collation] The collation of the database. If
 * createMode is not Default, this value is ignored.
 *
 * @param {string} [parameters.createMode] Specifies the mode of database
 * creation.
 *
 * Default: regular database creation.
 *
 * Copy: creates a database as a copy of an existing database. sourceDatabaseId
 * must be specified as the resource ID of the source database.
 *
 * OnlineSecondary/NonReadableSecondary: creates a database as a (readable or
 * nonreadable) secondary replica of an existing database. sourceDatabaseId
 * must be specified as the resource ID of the existing primary database.
 *
 * PointInTimeRestore: Creates a database by restoring a point in time backup
 * of an existing database. sourceDatabaseId must be specified as the resource
 * ID of the existing database, and restorePointInTime must be specified.
 *
 * Recovery: Creates a database by restoring a geo-replicated backup.
 * sourceDatabaseId must be specified as the recoverable database resource ID
 * to restore.
 *
 * Restore: Creates a database by restoring a backup of a deleted database.
 * sourceDatabaseId must be specified. If sourceDatabaseId is the database's
 * original resource ID, then sourceDatabaseDeletionDate must be specified.
 * Otherwise sourceDatabaseId must be the restorable dropped database resource
 * ID and sourceDatabaseDeletionDate is ignored. restorePointInTime may also be
 * specified to restore from an earlier point in time.
 *
 * RestoreLongTermRetentionBackup: Creates a database by restoring from a long
 * term retention vault. recoveryServicesRecoveryPointResourceId must be
 * specified as the recovery point resource ID.
 *
 * Copy, NonReadableSecondary, OnlineSecondary and
 * RestoreLongTermRetentionBackup are not supported for DataWarehouse edition.
 * Possible values include: 'Copy', 'Default', 'NonReadableSecondary',
 * 'OnlineSecondary', 'PointInTimeRestore', 'Recovery', 'Restore',
 * 'RestoreLongTermRetentionBackup'
 *
 * @param {string} [parameters.sourceDatabaseId] Conditional. If createMode is
 * Copy, NonReadableSecondary, OnlineSecondary, PointInTimeRestore, Recovery,
 * or Restore, then this value is required. Specifies the resource ID of the
 * source database. If createMode is NonReadableSecondary or OnlineSecondary,
 * the name of the source database must be the same as the new database being
 * created.
 *
 * @param {date} [parameters.sourceDatabaseDeletionDate] Conditional. If
 * createMode is Restore and sourceDatabaseId is the deleted database's
 * original resource id when it existed (as opposed to its current restorable
 * dropped database id), then this value is required. Specifies the time that
 * the database was deleted.
 *
 * @param {date} [parameters.restorePointInTime] Conditional. If createMode is
 * PointInTimeRestore, this value is required. If createMode is Restore, this
 * value is optional. Specifies the point in time (ISO8601 format) of the
 * source database that will be restored to create the new database. Must be
 * greater than or equal to the source database's earliestRestoreDate value.
 *
 * @param {date} [parameters.recoveryServicesRecoveryPointResourceId]
 * Conditional. If createMode is RestoreLongTermRetentionBackup, then this
 * value is required. Specifies the resource ID of the recovery point to
 * restore from.
 *
 * @param {string} [parameters.edition] The edition of the database. The
 * DatabaseEditions enumeration contains all the valid editions. If createMode
 * is NonReadableSecondary or OnlineSecondary, this value is ignored. To see

 * referred to by operationId: "Capabilities_ListByLocation."
 *
 * @param {uuid} [parameters.requestedServiceObjectiveId] The configured
 * service level objective ID of the database. This is the service level
 * objective that is in the process of being applied to the database. Once
 * successfully updated, it will match the value of currentServiceObjectiveId
 * property. If requestedServiceObjectiveId and requestedServiceObjectiveName
 * are both updated, the value of requestedServiceObjectiveId overrides the
 * value of requestedServiceObjectiveName. To see possible values, query the
 * capabilities API
 * (/subscriptions/{subscriptionId}/providers/Microsoft.Sql/locations/{locationID}/capabilities)
 * referred to by operationId: "Capabilities_ListByLocation."
 *
 * @param {string} [parameters.requestedServiceObjectiveName] The name of the
 * configured service level objective of the database. This is the service
 * level objective that is in the process of being applied to the database.
 * Once successfully updated, it will match the value of serviceLevelObjective
 * property. To see possible values, query the capabilities API
 * (/subscriptions/{subscriptionId}/providers/Microsoft.Sql/locations/{locationID}/capabilities)
 * referred to by operationId: "Capabilities_ListByLocation.". Possible values

 * 'P11', 'P15', 'System', 'System2', 'ElasticPool'
 *
 * @param {string} [parameters.elasticPoolName] The name of the elastic pool
 * the database is in. If elasticPoolName and requestedServiceObjectiveName are
 * both updated, the value of requestedServiceObjectiveName is ignored. Not
 * supported for DataWarehouse edition.
 *

 *
 * @param {string} parameters.location Resource location.
 *
 * @param {object} [options] Optional Parameters.
 *
 * @param {object} [options.customHeaders] Headers that will be added to the
