Tables And Exception Propagation
(Informatics Practices)
PL/SQl TABLEs combine characteristics of SQL tables and C/Pascal arrays.
Like SQL tables:
- consist of records (must have a numeric primary key)
- can grow/shrink as elements are added/removed
Exceptions
An exception is an unusual/erroneous condition encountered during execution:
- system error (e.g. "out of memory")
- error caused by user program
- warning issued by application
PL/SQL's exception handling allows these to be handled "cleanly" in a central place.
Syntax for exception handlers:
BEGIN
... Statements ...
EXCEPTION
WHEN ExcepName1 THEN Statements1;
WHEN ExcepName2 THEN Statements2;
...
END;
If an error occurs in Statements, control is transferred to:
- the exception handler in this block
- the exception handler at the next enclosing block
- ... and so on out to the system level
Example: Computing stock-market price/earnings ratio
DECLARE
pe_ratio NUMBER(5,1);
BEGIN
SELECT price/earnings INTO pe_ratio
FROM StocksWHERE company_name = 'Acme';
INSERT INTO Statistics(co_name, ratio)
VALUES ('Acme', pe_ratio);
COMMIT;
EXCEPTION
WHEN ZERO_DIVIDE THEN -- divide-by-zero errors
INSERT INTO Statistics(co_name, ratio)
VALUES ('Acme', 0.0);
-- other exception handlers
END;
