RODBC-Select*在Oracle上失败，但可以指定列

我被难住了。使用

RODBC

并连接到

Oracle

数据库，我成功地使用以下工具浏览了我的表：

sqlColumns(channel, "tablename", schema="schema")$COLUMN_NAME

我甚至可以使用以下方法查询表：

temp <- sqlQuery(channel, "SELECT Col1, Col2 FROM table")

temp <- sqlQuery(channel, "SELECT * FROM table")

 [1] PRIMARY_KEY    LASTMODIFIEDBY ?              ?.1            ?.2           
 [6] ?.3            ?.4            ?.5            ?.6            ?.7           
[11] ?.8            ?.9            ?.10           ?.11           ?.12          
[16] ?.13           ?.14          
<0 rows> (or 0-length row.names)
