我有这个函数用于从查询中获取值。我可能在执行或语法方面做错了。当我尝试使用其中的数据运行查询时,它很好,但是这个返回0项。
public function get_modified_event ($type, $id, $employee_id)
{
global $dbh;
$sql =<<<SQL
SELECT outlook_id
FROM dba.events
WHERE spine_item_type = :type
AND spine_id = :id
AND employee_id = :employee_id
SQL;
$stmt = $dbh->prepare( $sql );
$stmt->execute( array(
'id' => $id,
'type' => $type,
'employee_id' => $employee_id,
) );
$rows = $stmt->fetchAll( \PDO::FETCH_ASSOC );
return $rows['outlook_id'];
}
答案 0 :(得分:0)
您可以尝试重新编写部分代码,以便它使用这种格式:
<!-- App/Page resources -->
<ResourceDictionary>
<ControlTemplate x:Key="ThreeBorderBtn">
<Grid RowSpacing="0" ColumnSpacing="0" Margin="0">
<BoxView Margin="5" BackgroundColor="Purple" />
<BoxView Margin="10" BackgroundColor="Green" />
<BoxView Margin="15" BackgroundColor="Red" />
<ContentPresenter Margin="20" />
</Grid>
</ControlTemplate>
</ResourceDictionary>
<!-- Control usage -->
<!-- make sure to register xmlns:local namespace -->
<local:TemplatedButton
HeightRequest="100"
Text="Button Caption!"
TextColor="Teal"
Command="{Binding ClickCommand}"
BackgroundColor="White"
ControlTemplate="{StaticResource ThreeBorderBtn}" />
希望你能得到一些有意义的结果。
