However, the tests I conducted showed that this was not the case in the client software. Therefore, in a time-constrained SQL operation, we should consider using the statement object, unless the SQL commands are processed in batches.

A regular expression can be viewed as a powerful wildcard character (a universal match symbol). Most people should be familiar with wildcards, for example, when we see an expression such as "SAMS", then any string that starts with SAMS in a text string can match that expression. Regular expressions provide a matching mechanism that is more powerful than this wildcard, more complex control rules, and more functional. This article will be on.
