I need to run a .sql file in Golang with Sql Plus, which creates a table and a file named tb_data_20180502104923
. I named the .sql script as tb_data_20180502104923.sql
with contents as follows:
set headsep off
set pagesize 0
set trimspool on
set trimout on
create table tb_data_20180502104923
as
select * from tb_data;
spool tb_data_20180502104923.txt
SELECT data_id||';'||data_content FROM tb_data_20180502104923;
spool off
I have tried this with os/exec
like this:
func main(){
cmd := exec.Command("sqlplus -s admin/123#@172.10.1.211:1521/orcl < tb_data_20180502104923.sql")
var out, stderr bytes.Buffer
cmd.Stdout = &out
cmd.Stderr = &stderr
err := cmd.Run()
if err != nil {
log.Fatalf("Error executing query. Command Output: %+v\n: %+v, %v", out.String(), stderr.String(), err)
}
}
Which return me an error message:
2018/05/02 11:06:46 Error executing query. Command Output:
: , fork/exec sqlplus -s admin/123#@172.10.1.1:1521/orcl < tb_data_20180502104923.sql: no such file or directory
exit status 1
And if I change the cmd := exec.Command
statement to:
cmd := exec.Command("sqlplus", "-s", "admin/123#@172.10.1.211:1521/orcl", "< tb_data_20180502104923.sql")
It return me nothing, and both tabel & file tb_data_20180502104923
did not created.
Where did I do it wrong, or is using Sql Plus not possible in Golang? And if it's not possible, is there any other way to do what I need?
Allright, nevermind, looks like it's just my poor understanding on how to use os/exec
.
So in case someone doesn't know how to use it, here how I solve my own problem.
I change
cmd := exec.Command("sqlplus", "-s", "admin/123#@172.10.1.211:1521/orcl", "< tb_data_20180502104923.sql")
to
cmd := exec.Command("bash", "-c", "sqlplus -s admin/123#@172.10.1.211:1521/orcl < tb_data_20180502104923.sql")
The first parameter bash
is the kind of Shell you want to use,
the second parameter -c
is the argument of bash
,
and the third parameter is the command
which I want to execute.
Well, correct me if I'm wrong.
