Arina Ielchiieva created DRILL-5476: ---------------------------------------
Summary: Calculate return type precision value for substring functions (substring. substr, left, right) Key: DRILL-5476 URL: https://issues.apache.org/jira/browse/DRILL-5476 Project: Apache Drill Issue Type: Improvement Affects Versions: 1.10.0 Reporter: Arina Ielchiieva Priority: Minor Currently when applying substring / substr / left / right functions Drill doesn't calculate return length. Since we know calculation rules for these functions, we can predict return length. For example: substring(cast(col as varchar(10), 1, 5) -> varchar(5) substring(cast(col as varchar(10), 5) -> varchar(5) Similar changes has been done in DRILL-5419 for other string functions. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
