Jerin John updated CALCITE-5910:
--------------------------------
Description:
Add support for
[REGEXP_EXTRACT|https://cloud.google.com/bigquery/docs/reference/standard-sql/string_functions#regexp_extract]
and
[REGEXP_EXTRACT_ALL|https://cloud.google.com/bigquery/docs/reference/standard-sql/string_functions#regexp_extract_all]
functions from BigQuery.
*{{REGEXP_EXTRACT(value, regexp[, position[, occurrence]])}}*
Returns the substring in {{value}} that matches the regular expression
{{{}regexp{}}}. Returns {{NULL}} if there is no match.
* If the regular expression contains a capturing group ({{{}(...){}}}), and
there is a match for that capturing group, that match is returned. If there are
multiple matches for a capturing group, the last match is returned.
* If {{position}} is specified, the search starts at this position in
{{{}value{}}}, otherwise it starts at the beginning of {{{}value{}}}.
* If {{occurrence}} is specified, the search returns a specific occurrence of
the {{regexp}} in {{{}value{}}}, otherwise returns the first match.
*{{REGEXP_EXTRACT_ALL(value, regexp)}}*
Returns an array of all substrings of value that match the re2 regular
expression, regexp. Returns an empty array if there is no match.
was:
