Subject: [OASIS Issue Tracker] (ODATA-781) substring: what to return if the start index is outside the first argument string, or the desired length exceeds the remaining string length
[ https://issues.oasis-open.org/browse/ODATA-781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=58651#comment-58651 ] Evan Ireland commented on ODATA-781: ------------------------------------ What about using the precent established with JavaScript (to avoid unnecesarily speicfying undefined behaviour). https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/substring If indexA equals indexB, substring() returns an empty string. If indexB is omitted, substring() extracts characters to the end of the string. If either argument is less than 0 or is NaN, it is treated as if it were 0. If either argument is greater than stringName.length, it is treated as if it were stringName.length. > substring: what to return if the start index is outside the first argument string, or the desired length exceeds the remaining string length > -------------------------------------------------------------------------------------------------------------------------------------------- > > Key: ODATA-781 > URL: https://issues.oasis-open.org/browse/ODATA-781 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData URL Conventions > Affects Versions: V4.0_ERRATA02 > Environment: [Proposed] > Reporter: Ralf Handl > Fix For: V4.0_ERRATA03 > > > This could be a "bad request" returning no results at all, or it could evaluate to null, which may just lead to excluding the offending instance from the result. > Or a mix of both: negative start index is "bad request", start index or desired length beyond the end of the first argument is "null". -- This message was sent by Atlassian JIRA (v6.2.2#6258)
