CREATE STAGE [ IF NOT EXISTS ] <internal_stage_name>
[ FILE_FORMAT = ( { TYPE = { CSV | PARQUET } [ formatTypeOptions ] ) } ]
[ COPY_OPTIONS = ( copyOptions ) ]
[ COMMENT = '<string_literal>' ]

-- External stage
CREATE STAGE [ IF NOT EXISTS ] <external_stage_name>
externalStageParams
[ FILE_FORMAT = ( { TYPE = { CSV | PARQUET } [ formatTypeOptions ] ) } ]
[ COPY_OPTIONS = ( copyOptions ) ]
[ COMMENT = '<string_literal>' ]

Where:

externalStageParams (for Amazon S3)
