Mysql Script in Go using exec.Command

I hope this helps . The > is a shell metacharacter for output redirection. When you run a command in the shell, the shell pre-parses your command and does special things with input/output redirection. It does not pass the redirection metacharacters to the program. But when you use exec.Command(), you only give the arguments you want to pass to the command.
If you want to save the output of the command, you need to work with your cmd.Stdout buffer.

need to "build" a mysql command and exec it in a shell script

will help you I think the problem is in the quotes, the simple quote prevent the variable expansion. You can simply do like this in your script:
code :
    #create a new db

    mysql -u user -p password -e "create database $1;"
    #create a new db

    mysql -u user -p password "$1" < "$1.sql"

Any of those help Here's how timeout works w.r.t. exec().
So the first line in the exec() method is this:
code :
$this->curTimeout = $this->timeout;
$temp = $this->_get_channel_packet(self::CHANNEL_EXEC);
        if ($this->curTimeout) {
            if ($this->curTimeout < 0) {
                $this->is_timeout = true;
                return true;
            $read = array($this->fsock);
            $write = $except = null;
            $start = microtime(true);
            $sec = floor($this->curTimeout);
            $usec = 1000000 * ($this->curTimeout - $sec);
            // on windows this returns a "Warning: Invalid CRT parameters detected" error
            if (!@stream_select($read, $write, $except, $sec, $usec) && !count($read)) {
                $this->is_timeout = true;
                return true;
            $elapsed = microtime(true) - $start;
            $this->curTimeout-= $elapsed;
$ssh->write("cat /dev/urandom\n");

$start = microtime(true);
echo $ssh->exec('ping google.com');
$elapsed = microtime(true) - $start;

echo "took $elapsed seconds\n";

I think the issue was by ths following , +1 to answer from @MatteoRagni for showing how to do stdin redirection in Golang.
But here's a simple alternative that I use:
code :
cmd := exec.Command("/usr/local/mysql/bin/mysql", "-h127.0.0.1", "-P3333", 
  "-uusr", "-pPassxxx", "-Ddtb_test",
  "-e", "source /Users/XXX/Documents/test/scripts/olds/SCRIPT_XXX.sql")

terraform local-exec command for executing mysql script

help you fix your problem This is possible using a null_resource that depends on the aws_db_instance.my_db. This way the host is available when you run the command, it will only work if there aren't rules preventing you from accessing the DB such as security group ingress or not publicly accessible.
code :
resource "null_resource" "setup_db" {
  depends_on = ["aws_db_instance.my_db"] #wait for the db to be ready
  provisioner "local-exec" {
    command = "mysql -u ${aws_db_instance.my_db.username} -p${var.my_db_password} -h ${aws_db_instance.my_db.address} < file.sql"
