Question

表1 - 此表完全填充在XLSX文件中...

enter image description here

表2和3 - 包含最终表中几列的1-1引用。

enter image description here

表3 - 我正试图填充前三张表......

enter image description here

正如你所看到的，这些表是明智的，没有正在进行的爱因斯坦方程或转换。这是我已经尝试过的代码，但没有成功：

INSERT INTO att_oem_orders SELECT NULL, ost.om_or_po, (SELECT j.job_id FROM jobs j WHERE j.project_number = project_no), NULL, (SELECT ao.id FROM att_oem WHERE ao.item_no = item_no), ost.po_number, (SELECT ol.id FROM order_lsc WHERE STATUS = ol.line_status_code), ost.ordered_date, ost.shipment_date, NULL, NULL, ost.item_qty, NULL, NULL, NULL, NULL, ost.shipping_to, ost.tracking_number, ost.carrier) FROM oem_temp_sync WHERE ost.item_qty > 0

Answer 1

尝试使用FIRST（）限制要放入字段的可能值的数量，如下所示：

INSERT INTO att_oem_orders SELECT
    NULL,
    ost.om_or_po,
    (SELECT FIRST(j.job_id) FROM jobs j WHERE j.project_number = project_no),
    NULL,
    (SELECT FIRST(ao.id) FROM att_oem WHERE ao.item_no = item_no),
    ost.po_number,
    (SELECT FIRST(ol.id) FROM order_lsc WHERE STATUS = ol.line_status_code),
    ost.ordered_date,
    ost.shipment_date,
    NULL,
    NULL,
    ost.item_qty,
    NULL,
    NULL,
    NULL,
    NULL,
    ost.shipping_to,
    ost.tracking_number,
    ost.carrier
FROM oem_temp_sync WHERE ost.item_qty > 0

在FROM

之前，你似乎还有一个额外的东西

Answer 2

在每个人的帮助下，我发现了一些错误并修复了一些子查询。这是最终版本：

INSERT INTO att_oem_orders 
SELECT 
    NULL,
    ost.om_or_po,
    (SELECT 
        FIRST(j.id) 
    FROM
        jobs j 
    WHERE j.project_number = ost.project_no),
    NULL,
    (SELECT 
        FIRST(ao.id) 
    FROM
        att_oem ao
    WHERE ao.item_no = ost.item_no),
    ost.po_number,
    (SELECT 
        FIRST(ol.id) 
    FROM
        att_oem_lsc ol
    WHERE ol.status = ost.line_status_code),
    ost.ordered_date,
    ost.shipment_date,
    NULL,
    NULL,
    ost.item_qty,
    NULL,
    NULL,
    NULL,
    NULL,
    ost.ship_to,
    ost.tracking_no,
    ost.carrier
FROM
    oem_sync_temp  ost
WHERE ost.item_qty > 0

将数据从一个表传输到另一个表，一些关系列
