我创建了此代码，以便在TPC-H schema中创建MongoDB，并进行一些验证：
db.createCollection("lineItem", {
validator: {
$or: [
{
"lineNumber": { $type: "int"}
},
{
"quantity": { $type: "decimal"}
},
{
"extendedPrice": { $type: "decimal"}
},
{
"discount": { $type: "decimal"}
},
{
"tax": { $type: "decimal"}
},
{
"returnFlag": { $type: "string"}
},
{
"lineStatus": { $type: "string"}
},
{
"shipDate": { $type: "string"}
},
{
"commitDate": { $type: "string"}
},
{

{

},
{

},
{
"order.comment": { $type: "string"}
},
{
"order.customer.custKey": { $type: "int", $exists: true}

{

{
"order.customer.mktSegment": { $type: "string"}

{

{

},
{

},
{
"partSupp.availQty": { $type: "int"}
},
{
"partSupp.supplyCost": { $type: "decimal"}
},
{

},
{
"partSupp.part.partKey": { $type: "int", $exists: true}
},
{

},
{
"partSupp.part.mfgr": { $type: "string"}
},
{
"partSupp.part.brand": { $type: "string"}
},
{
"partSupp.part.type": { $type: "string"}
},
{
"partSupp.part.size": { $type: "int"}
},
{
"partSupp.part.container": { $type: "string"}

{

},
{

{

},
{

},
{

{
"partSupp.supplier.nation.region.regionName": { $type: "string"}
},
{
"partSupp.supplier.nation.region.comment": { $type: "string"}
}
]
}
})
它运行良好（我认为），但是，我在为上面这个集合创建插入代码时遇到了一些麻烦。这是我试图插入的内容：
db.lineItem.insertOne({
"lineNumber": 1,
"quantity": 17,
"extendedPrice": 24710.35,
"discount": 0.04,
"tax": 0.02,
"returnFlag": "N",
"lineStatus": "O",
"shipDate": "1996-03-13",
"commitDate": "1996-02-12",
"receiptDate": "1996-03-22",
"shipInstruct": "DELIVER IN PERSON",
"shipMode": "TRUCK",
"comment": "egular courts above the",
"order": {
"orderKey": 1,
"orderStatus": "O",
"totalPrice": 172799.49,
"orderDate": "1996-01-02",
"orderPriority": "5-LOW",
"clerk": "Clerk#000000951",
"shipPriority": 0,
"comment": "nstructions sleep furiously among ",
"customer": {
"custKey": 370,
"name": "Customer#000000370",
"address": "oyAPndV IN",
"phone": "22-524-280-8721",
"acctBal": 8982.79,
"mktSegment": "FURNITURE",
"comment": "ges. final packages haggle quickly. slyly bold ",
"nation": {
"nationKey": 12,
"name": "JAPAN",
"comment": "ously. final",
"region": {
"regionKey": 2,
"regionName": "ASIA",
"comment": "ges. thinly even pinto beans ca"
}
}
}
},
"partSupp": {
"availQty": 7030,
"supplyCost": 802.33,
"comment": "p about the enticingly quiet pinto beans. furiously ironic packages are care",
"part": {
"partKey": 1552,
"name": "plum chartreuse sky pale firebrick",
"mfgr": "Manufacturer#4",
"brand": "Brand#41",
"type": "SMALL POLISHED TIN",
"size": 10,
"container": "WRAP CASE",
"retailPrice": 1453.55,
"comment": "onic deposits"
},
"supplier": {
"suppKey": 93,
"name": "Supplier#000000093",
"address": "wd1djjKXT4zBm",
"phone": "26-528-528-1157",
"acctBal": 368.76,
"comment": "yly final accounts could are carefully. fluffily ironic instruct",
"nation": {
"nationKey": 16,
"name": "MOZAMBIQUE",
"comment": "s. ironic",
"region": {
"regionKey": 0,
"regionName": "AFRICA",
"comment": "lar deposits. blithely final packages cajole. regular waters are final requests. regular accounts are according to"
}
}
}
}
});
但是，在我尝试运行它之前，MongoDB控制台显示供应商使用以下代码：
... "supplier": {
... Display all 173 possibilities? (y or n)
当我在此集合中插入并运行find()时，supplier没有suppKey并且在其中显示ane而不是name < / p>
我已经看到this问题，询问同样的问题，但是，我没有提到这些空间。
我应该怎样做才能停止接收此错误？
答案 0 :(得分：0)
'> db.staffList.insert（... （已删除代码）
显示所有175种可能性？ （是或否）
尝试将代码复制到MS Word中，然后按按钮打开隐藏的字符。
在Excel中创建代码后，我遇到了同样的问题。该代码到处都是标签。移除这些标签，它应该有更好的工作机会。
（要摆脱Word中的制表符，请将^ t替换为空白。）
希望这会有所帮助。
