Jerin John commented on CALCITE-5978: ------------------------------------- Thanks for the feedback [~julianhyde], definitely agree and will keep in mind for future changes. I think the Github username issue would've been inconsistent between a commit I made from IDE UI v/s cmdline, apologies for that confusion. I understand the lack of clarity with that helper function, I'll update the naming and javadoc to make the functionality more explicit alongside the next commit. > Add REGEXP_INSTR function (enabled in BigQuery library) > ------------------------------------------------------- > > Key: CALCITE-5978 > URL: https://issues.apache.org/jira/browse/CALCITE-5978 > Project: Calcite > Issue Type: Task > Reporter: Jerin John > Assignee: Jerin John > Priority: Major > Labels: pull-request-available > Fix For: 1.36.0 > > > Add support for [REGEXP_INSTR > |https://cloud.google.com/bigquery/docs/reference/standard-sql/string_functions#regexp_instr] > function from BigQuery. > *{{REGEXP_INSTR(string, regexp [, position [, occurrence [, > occurrence_position]]])}}* > Returns the lowest 1-based position of the substring in {{string}} that > matches the {{{}regexp{}}}, Returns 0 if there is no match > * If {{position}} is specified, the search starts at this position in > {{{}string{}}}, otherwise it starts at the beginning of {{{}string{}}}. > * If {{occurrence}} is specified, the search returns index for the specific > occurrence of the {{regexp}} in value, otherwise returns the first match. > * If {{occurrence_position}} is specified as 1, returns the end index of > substring + 1 (default 0 returns start index of match) > Example: > {{SELECT REGEXP_INSTR("abcadcabcaecghi", "adc") as result;}} > |result| > |4| -- This message was sent by Atlassian Jira (v8.20.10#820010)
