we can create odbc_table use SQL like
```
CREATE EXTERNAL TABLE `baseall_oracle` (
`k1` decimal(9, 3) NOT NULL COMMENT "",
`k2` char(10) NOT NULL COMMENT "",
`k3` datetime NOT NULL COMMENT "",
`k5` varchar(20) NOT NULL COMMENT "",
`k6` double NOT NULL COMMENT ""
) ENGINE=ODBC
PROPERTIES (
"host" = "192.168.0.1",
"port" = "8086",
"user" = "happenlee",
"password" = "doris",
"database" = "doris",
"table" = "baseall",
"driver" = "Oracle 19 ODBC driver",
"type" = "oracle"
);
```
Now we only support Oracle and MySQL Database and this feature default turned off by conf enable_odbc_table.
