Anders: sqlite: cursor:toColumn Index
原标题:Android: sqlite: cursor: getColumnIndex

我对一个正常的qlite数据库进行了相当复杂的询问(多份合并)。 查询是<代码>SlectT *,使某些自动属性甄选逻辑(因此我可以删除“*”)

我面临的问题是,我的定本包含多栏,名称相同。 例如,在询问中,每个表格都有一个共同的“_id”。 当我打电话到cursor.getColumnIndex ("_id”)"时,所退还的价值始终是最后<代码>_id"在结果栏目清单中(即不是我想要的)的索引。 I d 热能使用我方位的座右铭,例如 曲线器.getColumnIndex(“A._id”),但这并非奏效。

  • It appears that cursor.getColumnIndex(AttributeName) returns the index of the last "AttributeName". Can anyone confirm this?
  • Also, any suggestions on how return the index of the 1st attribute with "AttributeName"? or better the Xth attribute having "AttributeName"?
最佳回答

你可以这样做:

SELECT _id as myID, * FROM myTable

这意味着<代码>_id。 每一表格的实地数字将两次,但两个栏中有一个独特的名称,可以找到。
