UPDATE OutfitItem
SET outfit_img_relative_pos_x=?,clothing_item_ID=?,outfit_img_relative_pos_y=?,
outfit_img_relative_size_width=?,outfit_ID=?,outfit_img_relative_size_height=?
WHERE (outfit_ID,clothing_item_ID) = (60,5)
有人可以为我找出错误吗?
以下是被编译的代码…
// ---updates a outfitItem---
public boolean update(long outfitID, long clothingItemID, double imgrelativePos_X, double imgrelativePos_Y,
double imgrelativeSize_width, double imgrelativeSize_height)
{
ContentValues args = new ContentValues();
args.put(KEY_OUTFIT_ID, outfitID);
args.put(KEY_CLOTHING_ITEM_ID, clothingItemID);
args.put(KEY_OUTFIT_IMAGE_RELATIVE_POS_X, imgrelativePos_X);
args.put(KEY_OUTFIT_IMAGE_RELATIVE_POS_Y, imgrelativePos_Y);
args.put(KEY_OUTFIT_IMAGE_RELATIVE_SIZE_WIDTH, imgrelativeSize_width);
args.put(KEY_OUTFIT_IMAGE_RELATIVE_SIZE_HEIGHT, imgrelativeSize_height);
return db.update(TABLE_NAME, args, "(" + KEY_OUTFIT_ID + "," + KEY_CLOTHING_ITEM_ID + ") = (" + outfitID
+ "," + clothingItemID + ")", null) > 0;
}
以下是创建表的代码,并注意将外键设置为on …
public static final String TABLE_NAME = "OutfitItem";
public static final String TABLE_CREATE = "create table " + TABLE_NAME + "(" + KEY_OUTFIT_ID
+ " int not null REFERENCES " + Table_Outfit.TABLE_NAME + "(" + KEY_OUTFIT_ID + ") ON DELETE CASCADE,"
+ KEY_CLOTHING_ITEM_ID + " int not null REFERENCES " + Table_ClothingItem.TABLE_NAME + "("
+ KEY_CLOTHING_ITEM_ID + ") ON DELETE CASCADE, " + KEY_OUTFIT_IMAGE_RELATIVE_POS_X + " real not null, "
+ KEY_OUTFIT_IMAGE_RELATIVE_POS_Y + " real not null, " + KEY_OUTFIT_IMAGE_RELATIVE_SIZE_WIDTH
+ " real not null, " + KEY_OUTFIT_IMAGE_RELATIVE_SIZE_HEIGHT + " real not null, " + "primary key ("
+ KEY_OUTFIT_ID + "," + KEY_CLOTHING_ITEM_ID + "));";
解决方法:
您的问题出在您的WHERE子句中:
WHERE (outfit_ID,clothing_item_ID) = (60,5)
这是无效的sql语法.您需要对AND联接使用单独的条件.
