Rank(): This function will assign the rank number to each record present in a partition. If the function in SQL encounters two equal values in the same partition, it will assign the same rank number to both values and skips the next number in the ranking for successive partitions. Dense_rank(): This function assigns rank number similar to the above function , but the ranks are consecutive for successive partitions . No ranks are skipped if there are ranks with multiple items. ...
air object changed: Compares two branches or versions of a single technical repository or two repositories, and identifies which objects have changed. The command outputs the list of files that have been added, removed, or changed between the source and target as follows: Code (meaning) Description A (Added) The file exists in the target but not in the source. R (Removed) The file exists in the source but not in the target. M (Modified) The file is different in the source and the target. S (Same) The file is the same in the source and the target. U (Unknown) The difference could not be determined. Occurs due to permission errors or when an object cannot be checked out. N (No object) The specified object does not exist in either the source or the target. air tag diff: ...
LOOKUP FUNCTION lookup_next() § Lookup_next will give you the next available match in the Lookup file. § Lookup_next should be Preceded after successful call to lookup, lookup_count, lookup_match, lookup_nth, lookup_range, or lookup_next itself. § The lookup_next function returns NULL if you call it more times than the number of matching records in the file, or if the next matching record does not exist. § Behavior of lookup_next() on different calls The next successive matching record after the previous call to lookup or lookup_range . ...
