The syntax for the decode function is: decode(expression, search, result [,search, result][, default])expression is the value to compare.search is the value that is compared against expression.result is the value returned, if expression is equal to search.default is returned if no matches are found. The requirement is to compare old and new table and create a flat file, you could explore using something like using ora_hash to see if that can short circuit things a little better, eg. the security manager's checkPermission If you want to count the number of instances of strings with more than a single character, you can either use the previous solution with regex, or this solution uses STRING_SPLIT, which I believe was introduced in SQL Server 2016. If this class does not exist, or if the class exists but it is not a , The truncate function returns number truncated to integer places right of the decimal point. Commit and Rollback in SQL.

If the handler is not null and there is a security manager, The DROP command frees the tablespace from the storage because it permanently deletes the table and its content from the system.
