Question

I have a database that needs to be updated periodically. My employer wants to keep a base instance of it in MS Access, and update one in a local SQLite table.

I’ve been able to grab all of the data out of the MS Access table (into XML), but when I try to insert it into the SQLite table, I get the error that there are too many terms in the compound select statement.

I know that SQLite limit compound select inserts to 500, but this database is over 150,000 rows. I’m at a loss for how to get the data moved over.

Anyone have any thoughts?

Here is the code that I was trying to use:

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 );
}

Here is an example of the XML that I am reading into the database:

<items>
    <item>
        <itemID>1234</itemID>
        <barcode>01111111111111</barcode>

        <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>

        <chgDate>1/9/2009 3:32:29 PM</chgDate>
    </item>
    <item>
        <itemID>1234</itemID>
        <barcode>01111111111111</barcode>

        <price>0.85</price>
        <brand>Product Brand</brand>
        <cat01>Product Category</cat01>
        <catSub>(none)</catSub>
        <cost>0.10</cost>
        <srp>0.95</srp>

        <chgDate>1/9/2009 3:32:29 PM</chgDate>
    </item>
</items>

Try this solution it works!!! I have tested this solution even in Web Sql DB based on sqlite

select 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
)
...
