from_file
Target database: Snowflake, Azure SQL Database
Resolved as the source file path in file load execution.

Notes
Supported in file loads.
Bucket/container address is stripped from the file path.
Examples
Snowflake: Variable used in OVERRIDE_FILE_LOAD
Manifest
<from_file> is resolved as the manifest path without bucket/container address, for example:
manifest/ratecode_description/manifest-table.ratecode_description.1619681245.batch.1619681245640.fullscanned.false.skiph.1.delim.comma.csv.gz.json
Note that the manifest path is not useful in file loading terms in the Snowflake context. Therefore, <from_file> should be used with Snowflake in manifest loads only for metadata purposes.
Single file load
<from_file> is resolved as the source file path without bucket/container address, for example:
ratecode_description/table.ratecode_description.1619598629.batch.1619598629291.fullscanned.false.skiph.1.delim.comma.csv.gz
Azure SQL Database: Variable used in OVERRIDE_FILE_LOAD
<from_file> is similar to <from_path>, only the single quotes are omitted. See Azure SQL Database examples in <from_path>.
Manifest
File queued with a manifest:
taxidata1/ratecode_description.batch.1618916378963.csv
<from_file> is resolved as a file path in a manifest entry, for example:
taxidata1/ratecode_description.batch.1618916378963.csv
Single file load
File queued:
azure://example.blob.core.windows.net/example-container/taxidata1/ratecode_description.1619598629.batch.1619598629291.fullscanned.false.skiph.1.delim.comma.csv
<from_file> is resolved as the file path without the bucket/container address:
