An error occured while accessing a database. See
Alzabo::Driverfor more details.
An attempt to eval something returned an error.
Alzabo was asked to do something logically impossible, like retrieve rows for a table without a primary key.
An attempt was made to fetch data from the database with a primary key that does not actually exist in the specified table.
An attempt was made to set a non-nullable column to
NULL. The "column_name", "table_name", and "schema_name" fields can be used to identify the exact column.
This exception is thrown when something completely unexpected happens (think Monty Python).
This exception is thrown when there is a problem with the parameters passed to a method or function. These problems can include missing parameters, invalid values, etc.
A rule for the relevant RDBMS was violated (bad schema name, table name, column attribute, etc.)
An insert/update/delete was attempted that would violate referential integrity constraints.
An error thrown when there is an attempt to generate invalid SQL via the Alzabo::SQLMaker module.
A error when trying to freeze, thaw, or clone an object using Storable.
Some sort of system call (file read/write, stat, etc.) failed.
A virtual method was called. This indicates that this method should be subclassed.
