Encode directive

The ENCODE directive encodes a column value as one of base32, base64, hex or url following RFC-4648.

Syntax

encode <base32|base64|hex> :column

The syntax for encoding a column as url is:

url-encode :column

The :column is the name of the column to which the encoding is applied.

Usage Notes

Base encoding of data is used in many situations to store or transfer data in environments that, for legacy reasons, are restricted to US-ASCII data. Base encoding can be used in new applications that do not have legacy restrictions because it allows the manipulation of objects with text editors.

The ENCODE directive generates a new column with a name following the format of <column>_encode_<type>.

Different column values are handled following these rules:

If the column is null, the resulting column will also be null.
If the column specified is not found in the record, then the record is skipped as a no-op.
If the column value is not of either type string or byte array, it fails.

Example

Using this record as an example:

{
  "col1": "Base32 Encoding",
  "col2": "Testing Base 64 Encoding",
  "col3": "Hex Encoding"
  "col4": "Mr.Owen HarrisBraund"
}

Applying these directives:
