pl sql programs examples

Sometimes, we may find that some functions are difficult to complete through PL/SQL, while programming through C/C ++ is much easier. Therefore,OracleProvides the ability to directly call external functions (including C functions or Java methods) in PL/SQL programs, thus ext

. These datatypes are not supported ed in this article. In practice, you may encounter other numeric types, such as float, integer, and decimal. These are subtypes of the four core numeric types in the preceding list. Now let's take a closer look at number and pls_integer. The number datatype. the number data-type is by far the most common numeric datatype you'll encounter in the world of Oracle and PL/SQL

This cause may be related to the version, because it cannot be ruled out by some unknown factors solved by the re-installation. The test results are as follows: 3.
