Jerin John created CALCITE-5911: ----------------------------------- Summary: Implement BigQuery function REGEXP_EXTRACT_ALL Key: CALCITE-5911 URL: https://issues.apache.org/jira/browse/CALCITE-5911 Project: Calcite Issue Type: Task Reporter: Jerin John Assignee: Jerin John
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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
