ResourcePool::Command::DBI::SelectRow - A DBI command to execute one-row select statements.
# simple usage
my $cmd = ResourcePool::Command::DBI::SelectRow->new();
my @row = $pool->execute($cmd
, 'select id, name, value from test where id = ?'
# @row holds an array holding three values corresponding to the
# selected fields
This command can be used to execute one-row select statements in a DBI database using the ResourcePool command execution environment.
In order to understand this Class, and more importantly this document, you need to know a few terms I use in this document, if you are new to this class you should read the TERMS sections of ResourcePool::Command::DBI::Executefirst.
The use of this class if safe for all databases and drivers. If the select does not return any rows, the array returned by the execute() method will be empty. If the statement returns more than one record, only the first is fetched and returned.
Instantiates a new Select object. The parameters are identical to those of the ResourcePool::Command::DBI::Execute class.
Similar to the same named method of the ResourcePool::Command::DBI::Execute class. The only difference is that it returns an array holding the columns of the selected row.
Year, we really need documentation.
