我的sqlSave
查询与(连接到 MS )完美配合fast = TRUE
失败并出现以下错误:fast = FALSE
.accdb
> db <- odbcConnectAccess2007(PATH_OUT)
> sqlSave(db, df, "tblTest", rownames = F, append = T, fast = F)
Error in .Call("RODBCTypeInfo", attr(channel, "handle_ptr"), as.integer(type), :
"RODBCTypeInfo" not available for .Call() for package "RODBC"
> traceback()
4: .Call("RODBCTypeInfo", attr(channel, "handle_ptr"), as.integer(type),
PACKAGE = "RODBC")
3: sqlTypeInfo(channel)
2: sqlwrite(channel, tablename, dat, verbose = verbose, fast = fast,
test = test, nastring = nastring)
1: sqlSave(db, df, "tblTest", rownames = F, append = T, fast = F)
我自己不理解错误消息,所以有什么想法吗?
(我只是想测试会慢多少fast = FALSE
)
