Question

* 突然间，查询开始显示没有这样的表，但直到昨天才正常工作。坚持这段代码。请帮忙*

点击

public void onClick（查看arg0）{

            String stckCenterid=String.valueOf(headerDb.getStockCenterId(dat1));                    
            String stockItemId=String.valueOf(headerDb.getStockItemId(stckCenterid));

            System.out.println("StockCenterid, Stockitemid " + stckCenterid +"  "+ stockItemId);

        headerDb.getStockLedger(stckCenterid,stockItemId,from_date_format,to_date_format);




        }
        });

此库存中心ID正在按需要发送，但我将其传递给getstockitemid，但查询显示的不是此类表格，即下面的查询。我将这些中心ID和商品ID传递给另一个查询以获得结果

查询

public int getStockItemId(String stCenterId) {
        db = this.getReadableDatabase();
        Cursor c = db.rawQuery("SELECT STOCK_ITEM_ID from qt_um_stock_items_qty WHERE " +
                " STOCK_CENTRE_ID " + " = ? " , new String[] { stCenterId });
        c.moveToFirst();
        int index = c.getColumnIndex("STOCK_ITEM_ID");
        return c.getInt(index);

    }

logcat的

Answer 1

问题来自结构严密的代码：

总是在这里做一个String query =“SELECT ...”//查询将查询记录到控制台中以检查语法。

在大写SELECT，INSERT，FROM，WHERE中编写sql命令在SQL关键字后使用新行

做一个：

SELECT * FROM qt_um_stock_items_qty;

确保表格存在。

SQLite查询已停止工作
