An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) pl sql exception handling best practices and ORA-27102 (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 your own exceptions 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. 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 or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. 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. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error. pe_ratio := stock_price / net_earnings; DBMS_OUTPUT.PUT_LINE('Price/earnings ratio = ' || pe_ratio); EXCEPTION -- exception handlers begin -- Only one of the WHEN blocks is executed.

The USER_DUMP_DEST initialization parameter specifies https://docs.oracle.com/database/121/LNPLS/errors.htm the current location of the trace files. You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST. For more information about trace files, see Oracle Database Performance Tuning Guide. Compile-Time Warnings While compiling stored PL/SQL units, the PL/SQL compiler generates warnings for conditions that are not serious enough to cause errors and prevent compilation—for example, using a deprecated PL/SQL feature. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. The message code of a PL/SQL warning has the form PLW-nnnnn. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages Reference. Table 11-1 summarizes the categories of warnings. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results.

My code is as followed: DECLARE TYPE lv_student_ID IS TABLE OF NUMBER; BEGIN -- assuming you are trying to find all students who have not yet paid, you can use a nested table SELECT Lease.StudentIDNumber INTO lv_student_ID FROM Lease INNER JOIN Invoice ON Lease.LeaseID = Invoice.LeaseID WHERE IsPaid = 'N'; END; When I run this I get the errors which are as followed: Error report - ORA-06550: line 6, column 38: PLS-00321: expression 'LV_STUDENT_ID' is inappropriate as the left hand side of an assignment statement ORA-06550: line 7, column 6: PL/SQL: ORA-00904: : invalid identifier ORA-06550: line 6, column 4: PL/SQL: SQL Statement ignored 06550. 00000 - "line %s, column %s:\n%s" *Cause: Usually a PL/SQL compilation error. *Action: Any help would be greatly appreciated! sql plsql share|improve this question asked Apr 8 at 19:45 Josh 11 1 You are trying to save data into a type. You want to save data into a variable. And, if you only have one row, then into a scalar variable. –Gordon Linoff Apr 8 at 19:46 How would I go about doing that?? –Josh Apr 8 at 19:47 Are you attempting to select one, and only one, value into the collection, or possibly multiple values into the collection? –rgettman Apr 8 at 19:57 Basically im trying to find the number of students who haven't paid rent using PL/SQL –Josh Apr 8 at 20:04 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote To correct your immediate problem, you must recognize that you're attempting to select a scalar value (a number) into a collection type (a table of number), which doesn't work. To get this working, you first need to declare a variable of that type. Then you can add a bulk collect clause to your query, which changes the semantics of the select into selecting into collection(s). DECLARE TYPE lv_student_ID IS TABLE OF NUMBER; student_ids lv_student_id; BEGIN SELECT Lease.StudentIDNumber BULK COLLECT INTO student_i
