数据库可选参数错误

Question

我的动态查询有问题，因为我有一些空值。如果它没有任何值，我已经将值设为可选，但我仍然收到错误。有什么想法吗？

这是我在数据库连接器上的动态查询。我认为问题在于 BROKER 和 COTTON 组织声明

insert into [AWH_PrjPathFinder].[dbo].[ws_balesDataExt] values ('#[payload['FULLDATE']]', '#[payload.BROKER = (payload['BROKER'] == null) ? '' : payload.BROKER.toString()]', '#[payload.CENTER = ( payload['CENTER'] == null) ? '' : payload.CENTER.toString()]', '#[payload.DATATYPE = ( payload['DATATYPE'] == null) ? '' : payload.DATATYPE.toString()]','#[payload.COTTONORG = (payload['COTTONORG'] == null) ? '' : payload.COTTONORG.toString()]',#[payload['UNIT']],'#[payload['dateDataEnteredInAGDB']]')

这是我的示例输入文件。

[ {
"FULLDATE": "28/09/2015",
"CENTER": "B",
"DATATYPE": "CDLV",
"UNIT": "195" },
{
"FULLDATE": "28/09/2015",
"CENTER": "M",
"DATATYPE": "CRCV",
"UNIT": "47"
},
{
"FULLDATE": "28/09/2015",
"CENTER": "M",
"DATATYPE": "CRCV",
"UNIT": "60"
},
{
"FULLDATE": "28/09/2015",
"CENTER": "M",
"DATATYPE": "DDMP",
"UNIT": "84"
 },
 {
 "FULLDATE": "28/09/2015",
"CENTER": "M",
"DATATYPE": "DRCV",
"UNIT": "24"
  },

在形成插入时，您应该始终指定列（以正确的顺序）（这一点由 Gordon Linoff 提出）。

例如（下面的第二行已经添加 - 这是一个猜测）

INSERT INTO [AWH_PrjPathFinder].[dbo].[ws_balesDataExt] 
    ([FULLDATE],[BROKER],[CENTER],[DATATYPE],[COTTONORG],[UNIT],[dateDataEnteredInAGDB])
VALUES 
      (   '#[payload['FULLDATE']]'
        , '#[payload.BROKER = (payload['BROKER'] == null) ? '' : payload.BROKER.toString()]'
        , '#[payload.CENTER = ( payload['CENTER'] == null) ? '' : payload.CENTER.toString()]'
        , '#[payload.DATATYPE = ( payload['DATATYPE'] == null) ? '' : payload.DATATYPE.toString()]'
        , '#[payload.COTTONORG = (payload['COTTONORG'] == null) ? '' : payload.COTTONORG.toString()]'
        , '#[payload['UNIT']]
        , '#[payload['dateDataEnteredInAGDB']]'
      )
