Example 1. Retrieving column metadata
The following example shows the results of retrieving the metadata for a
single column generated by a function (COUNT) in a PDO_SQLITE driver.
<?php
$select = $DB->query('SELECT COUNT(*) FROM fruit');
$meta = $select->getColumnMeta(0);
var_dump($meta);
?> |
The above example will output:
array(6) {
["native_type"]=>
string(7) "integer"
["flags"]=>
array(0) {
}
["name"]=>
string(8) "COUNT(*)"
["len"]=>
int(-1)
["precision"]=>
int(0)
["pdo_type"]=>
int(2)
} |
