在android中查询sqlite(插入查询)

Question

我想插入数据库..一个表单的值..其中两个是整数,一个是字符串..但我无法在我的sqlite数据库查看器中查看我输入的值..我正在使用以下码:

SQLiteDatabase myDB= null;
      String TableName = "basicdetai";
     try{ 

          myDB = this.openOrCreateDatabase("Medical", MODE_PRIVATE, null); 

          /* Create a Table in the Database. */
         myDB.execSQL("CREATE TABLE IF NOT EXISTS "
            + TableName
            + " (order_id INT(4), doc_id INT(4),doc_name VARCHAR );");
         /* Insert data to a Table*/
          myDB.execSQL("INSERT INTO "
            + TableName
            + "(order_id,doc_id,doc_name)"
           + " VALUES ("+ ordid + ","+ doci + ","+ docnam +");");
        // line 10  + " VALUES ("+ a + ","+ b + ","+ docnam +");");
        //  line 11  +"VALUES (5011,4011,'gupta');");



      }
      catch(Exception e) {
          Log.e("Error", "Error", e);
         } 
      finally {
           if (myDB != null)
            myDB.close();
          }

但是当我在上面的代码中使用第11行时,我可以(5011,4011,'gupta')通过sqlite浏览器看到记录.我正在执行以下操作,以将我从表单获取的字符串值转换为整数

try {
          ordid = Integer.parseInt(orderid.getText().toString());
          doci = Integer.parseInt(docid.getText().toString());
         // qn = Integer.parseInt(qty.getText().toString());
      } catch(NumberFormatException nfe) {
         System.out.println("Could not parse " + nfe);
      }

Plz帮助..

Answer 1

请尝试以下查询...

db.execSQL("insert into your table name (order_id,doc_id,doc_name)" + "values("ordid+","+doci+","
                + "\"" + docnam + "\"" + ") ;");

Android有一些帮助INSERT的帮助类.你为什么不用它们？

例:

    public void addLibrary(LibraryItem item) {
    ContentValues row = new ContentValues();
    row.put("title", item.getTitle());
    row.put("author", item.getAuthor());
    row.put("publisher", item.getPublisher());
    row.put("thumbnailUrl", item.getThumbnail());
    row.put("formatType", item.getFormat());
    row.put("contentUrl", item.getContentUrl());
    row.put("publicationType", item.getPublicationType());
    row.put("favorite", item.isFavorite() ? "YES" : "NO");
    row.put("id", item.getItemId());
    row.put("normalizedTitle", StringUtil.normalize(item.getTitle()));
    row.put("downloaded", item.hasContent() ? Calendar.getInstance()
            .getTimeInMillis() : 0);
    row.put("wasdownloaded", item.hasContent() ? "YES" : "NO");
    row.put("bookmarked", "NO");
    row.put("archived", "NO");

    long id = db.insert("LIBRARY", null, row);
    }
