zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence http://stackoverflow.com/questions/1256112/pl-sql-block-problem-no-data-found of errors.

Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment.

Oracle PL/SQL "select into" clause Oracle Database Tips by Burleson Consulting The SELECT INTO Clause The SELECT INTO clause of http://www.orafaq.com/forum/t/64199/ SQL is used to retrieve one row or set of columns from the Oracle database. The SELECT INTO is actually a standard SQL query where the SELECT INTO clause is used to no data place the returned data into predefined variables. SQL> declare 2 v_authName author.author_last_name%type; 3 begin 4 select 5 author_last_name into v_authName 6 from 7 author 8 where 9 author_key = 'A103'; 10 11 dbms_output.put_line('Name: '||v_authName); 12 end; 13 / Name: weaton Here the author_key was used to retrieve one author's last name and no data found place it in the variable called v_authName. The query can also retrieve an entire row as a record with SELECT INTO. In the example below a record based on the columns of the author table is declared in line two below. Because v_author is declared as an author table %rowtype , you can safely use the SELECT * clause to retrieve all the columns. SQL> declare 2 v_author author%rowtype; 3 begin 4 select 5 * into v_author 6 from 7 author 8 where 9 author_key = 'A103'; 10 11 dbms_output.put_line('Name: '||v_author.author_first_name||' '|| v_author.author_last_name); 12 end; 13 / Name: erin weaton If the DBA adds a column to the author table, the query above will still execute. The record variable v_author contains a record that includes all the columns in the author table. If the value of a column in the table is NULL, it will also be NULL in the record. The individual columns are accessed using the dot "." notation with SELECT INTO.

How can I do that? It never enters the IF condition and throws error. Here is the code: select Cust_Addr into v_cust_addr from Cust_Name_Addr where cust_id = v_cust_id; if v_cust_addr is null then select Cust_Addr into v_cust_addr from Cust_History where cust_id = v_cust_id; else v_curr_cust := 1; end if; Report message to a moderator Re: NO DATA FOUND ERROR [message #175289 is a reply to message #175281] Thu, 01 June 2006 09:28 Art Metzer Messages: 2478Registered: December 2002 Senior Member You need to trap the NO_DATA_FOUND exception, and handle it.

Can I include the NO_DATA_EXECPTION for each query separately?

You can nest these blocks--see this link to the documentation for more details.

However, you could also "fool" Oracle and avoid NO-DATA-FOUND error if you put it like this: SELECT MAX(Cust_Addr) INTO v_cust_addr FROM Cust_Name_Addr WHERE cust_id = v_cust_id; That way you'll get NULL instead of NO-DATA-FO
