在我的大查询表中，我刚刚在记录类型字段“ A”内添加了另一个记录类型字段“ B”。在标准SQL方言中，我无法按以下方式查询B的重复字段： 从其中_partitiontime =;
中选择A.B.field1，A.B.field2，...用于以下查询-
SELECT ad_request_custom_targeting.iom.size,
ad_request_custom_targeting.iom.bidprice FROM `nyt-adtech-
prd.dfp_data.dfp_log_network_requests` WHERE DATE(_PARTITIONTIME) = "2019-
05-03" LIMIT 1000
我收到以下错误消息： 无法访问[1:40]处类型为“ ARRAY>”的值的字段大小
答案 0 :(得分：0)
对于BigQuery标准SQL
我认为在您的示例中
private void button1_Click(object sender, EventArgs e)
{
int count;
// Validate input
if (!int.TryParse(textBox1.Text, out count) || count < 0)
{
MessageBox.Show("Please enter a positive whole number");
return;
}
// remove old buttons (except this one)
var otherButtons = Controls.OfType<Button>().Where(b => b != button1).ToList();
foreach (Button b in otherButtons)
{
Controls.Remove(b);
}
// Add button controls to form with these size and spacing values (modify as desired)
var width = 25;
var height = 25;
var padding = 2;
// For each row, increment the top by the height plus padding
for (int row = 0, top = padding; row < count; row++, top += height + padding)
{
// For each column, increment the left by the width plus padding
for (int col = 0, left = padding; col < count; col++, left += width + padding)
{
// Add our new button
Controls.Add(new Button
{
Top = top,
Left = left,
Width = width,
Height = height,
});
}
}
}
是A，而ad_request_custom_targeting是B
