Description

Usage
=====

   oci data-safe target-database list-columns [OPTIONS]


Required Parameters
===================

--target-database-id [text]

The OCID of the Data Safe target database.


Optional Parameters
===================

--all

Fetches all pages of results. If you provide this option, then you
cannot provide the "--limit" option.

--column-name [text]

A filter to return only a specific column based on column name.

--column-name-contains [text]

A filter to return only items if column name contains a specific
string.

--datatype [text]

A filter to return only items related to specific datatype.

--from-json [text]

Provide input to this command as a JSON document from a file using the
file://path-to/file syntax.

The "--generate-full-command-json-input" option can be used to
generate a sample json file to be used with this command option. The
key names are pre-populated and match the command option names
(converted to camelCase format, e.g. compartment-id –> compartmentId),
while the values of the keys need to be populated by the user before
using the sample file as an input to this command. For any command
option that accepts multiple values, the value of the key can be a
JSON array.

Options can still be provided on the command line. If an option exists
in both the JSON document and the command line then the command line
specified value will be used.

For examples on usage of this option, please see our “using CLI with
advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Conte
nt/API/SDKDocs/cliusing.htm#AdvancedJSONOptions
