Question

我有一个需要定期更新的数据库。我的雇主希望在MS Access中保留它的基本实例，并在本地SQLite表中更新一个。

我已经能够从MS Access表中获取所有数据（到XML中），但是当我尝试将其插入到SQLite表中时，我得到的错误是复合词中有太多术语选择陈述。

我知道SQLite限制复合选择插入到500，但是这个数据库超过150,000行。我对如何移动数据感到茫然。

有人有任何想法吗？

以下是我尝试使用的代码：

var sqlItem:String="INSERT INTO items (itemID,barcode,desc,brandNum,size,units,multQty,multPrice,price,brand,cat01,catSub,cost,srp,lastPriceChangeDate,lastScanDate,addDate,chgDate) ";
for each(var i:XML in itemList.item){
    sqlItem=sqlItem+"SELECT "+
    parseInt(i.itemID,10)+","+
    parseInt(i.barcode,10)+","+
    "\""+i.description+"\","+
    parseInt(i.brandNum,10)+","+
    "\""+i.size+"\","+
    "\""+i.units+"\","+
    parseInt(i.multQty,10)+","+
    "\""+i.multPrice+"\","+
    "\""+i.price+"\","+
    "\""+i.brand+"\","+
    "\""+i.cat01+"\","+
    "\""+i.catSub+"\","+
    "\""+i.cost+"\","+
    "\""+i.srp+"\","+
    "\""+i.lastPriceChangeDate+"\","+
    "\""+i.lastScanDate+"\","+
    "\""+i.addDate+"\","+
    "\""+i.chgDate+"\""+
    " UNION ";
}
sqlItem=sqlItem.substring(0,sqlItem.length-7);
itemStmt.text=sqlItem;
try{
    itemStmt.execute();
}catch(error:SQLError){
    trace("Update USER Database - ERROR: "+error.detailID +" - "+error.details );
}

以下是我正在读入数据库的XML示例：

<items>
    <item>
        <itemID>1234</itemID>
        <barcode>01111111111111</barcode>
        <description>Product Description</description>
        <brandNum>1</brandNum>
        <size>1</size>
        <units>oz.</units>
        <multQty>1</multQty>
        <multPrice>0.85</multPrice>
        <price>0.85</price>
        <brand>Product Brand</brand>
        <cat01>Product Category</cat01>
        <catSub>(none)</catSub>
        <cost>0.10</cost>
        <srp>0.95</srp>
        <lastPriceChangeDate>1/9/2009 3:32:29 PM</lastPriceChangeDate>
        <lastScanDate>1/9/2009 3:32:29 PM<lastScanDate>
        <addDate/>1/9/2009 3:32:29 PM<addDate/>
        <chgDate>1/9/2009 3:32:29 PM</chgDate>
    </item>
    <item>
        <itemID>1234</itemID>
        <barcode>01111111111111</barcode>
        <description>Product Description</description>

        <multPrice>0.85</multPrice>
        <price>0.85</price>
        <brand>Product Brand</brand>
        <cat01>Product Category</cat01>
        <catSub>(none)</catSub>
        <cost>0.10</cost>
        <srp>0.95</srp>
        <lastPriceChangeDate>1/9/2009 3:32:29 PM</lastPriceChangeDate>
        <lastScanDate>1/9/2009 3:32:29 PM<lastScanDate>
        <addDate/>1/9/2009 3:32:29 PM<addDate/>
        <chgDate>1/9/2009 3:32:29 PM</chgDate>
    </item>
</items>

试试这个解决方案吧!!!我甚至在基于sqlite的Web Sql DB中测试了这个解决方案

选择sqlite_version（）

3.6.19

INSERT INTO items (val)  
select * from
(select 1  val  union all
 select 2   val union all
 select 3   val union all
 select 4   val union all
 ...
 select 500 val
)
union all
select * from
(select 501  val    union all
 select 502 val union all
 select 503 val union all
 select 504 val union all
 ...
 select 1000    val
)
union all
select * from
(select 1001  val   union all
 select 1002    val union all
 select 1003    val union all
 select 1004    val union all
 ...
 select 1500    val
)
...

将超过100,000条记录插入SQLite
