You need to create a small PL/SQL function: create or replace function isnum(v_in varchar2) return varchar is val_err exception; pragma exception_init(val_err, -6502); -- char to num conv. error scrub_num number; begin scrub_num := to_number(v_in); return 'Y'; exception when val_err then return 'N'; end; / If the value passed into the ISNUM function is a number, then a Y is returned. If the value cannot be converted to a number, then an N is returned.

You can use the ISNUM function to detect whether data in a column is numeric. The function defines a PL/SQL pragma exception for the ORA-06502 character-to-number conversion error. When this error is encountered, the exception handler captures it and returns an N.

That is why the most modern (well, JDK 13) style of registration comes with a solution based on the classpath You can simply put a JAR file with an implementation on the classpath and then the API can find its implementation(s) immediately The Java API for XML Processing (JAXP) is an example of this approach Most of the API consists of interfaces in public packages In addition, there are also a few factories, such as DocumentBuilderFactory The factories look for the implementations using a documented search procedure: scanning for META-INF/ services/pkgnameClassName entries..

As mentioned, an alternative is to create the WebProxy class in the same way but assign the Proxy property of your Web request to an instance of the WebProxy class created previously, as shown here: System.Net.WebRequest req = System.Net.HttpWebRequest.Create(uri); req.Proxy = new System.Net.WebProxy(proxyUri);

You can use this function to determine if a character can be converted to a number. For example, say you have a table named STAGE and it contains a column named HOLD_COL with the following values in it: HOLD_COL -----------------------------1 c 3 $ 1032.22 32423432234234432x The following query uses the ISNUM function to determine if there is any non-numeric data in the table: select hold_col from stage where isnum(hold_col)='N'; Here is the expected output: HOLD_COL -----------------------------c $ 32423432234234432x

Clients compile against the interface module, and can express a request that at least one implementation module must be available at runtime so the factories work. Alternatively, the API module itself might raise such a request. Moreover, there can be multiple versions of the vendor implementations; each can automatically be registered and can then be found by the API module. A real modular architecture is likely to encourage a modular library design and probably also uses the simple library approach, where appropriate. Solving the multiple vendors problem by copying the classes is simply not good design in a modular world, because you duplicate the actual .class files of the specification across vendors. Furthermore, the copy-based approach doesn t permit easy publishing of a revision to the specification independently of updates to vendor implementations. You need to use special semantics such as, This JAR provides such-and-such specification version such-and-such implementation, which the module system has to interpret somehow. By contrast, the modular library approach is straightforward in a modular system, and you don t even need special semantics for specification or implementation. A specification is simply a module that exposes some packages with interfaces and a factory or two, and is accompanied by documentation explaining its permissible behavior. An implementation is simply a module without exposed packages that depends on the specification module and registers implementations of the factories into your service registration system (whatever that is). A client is a module that depends on the specification module and calls the factory methods.

Note In the previous example, the proxy does not need the user to be authenticated; that is, it doesn t need a username and password. This may not be the case for all proxy servers, in which case you will need to provide the appropriate username and password.

You have a field that has been defined as a character string in the old system but will be migrated to a date data type in the new database. You have the data loaded into a temporary holding table and you want to determine if any of the character data will not convert cleanly to a date data type.
