Github user paul-rogers commented on a diff in the pull request: https://github.com/apache/drill/pull/819#discussion_r113605335 --- Diff: common/src/main/java/org/apache/drill/common/types/Types.java --- @@ -340,18 +344,18 @@ public static int getJdbcDisplaySize(MajorType type) { case INTERVALYEAR: return precision > 0 ? 5 + precision // P..Y12M - : 0; // if precision is not set, return 0 because there's not enough info + : UNDEFINED; // if precision is not set, return 0 because there's not enough info --- End diff -- We actually do know. INTERVALYEAR is stored as a signed 4 byte int, so the maximum number of months is known. From that, we can estimate the string form: PxY12M where x = Integer.MAX_VALUE / 12. Realistically, assuming a range of +/- 10K years is good enough, so: P9999Y12M Is the maximum value.
