对应的源码程序再/client/mysql.cc中
static int
com_status(String *buffer __attribute__((unused)),
char *line __attribute__((unused)))
{
const char *status_str;
char buff[40];
ulonglong id;
MYSQL_RES *result;
LINT_INIT(result);
if (mysql_real_query_for_lazy(
C_STRING_WITH_LEN("select DATABASE(), USER() limit 1")))
return 0;
tee_puts("--------------", stdout);
usage(1); /* Print version */
tee_fprintf(stdout, "\nConnection id:\t\t%lu\n",mysql_thread_id(&mysql));
/*
Don't remove "limit 1",
it is protection againts SQL_SELECT_LIMIT=0
*/
if (!mysql_store_result_for_lazy(&result))
{
MYSQL_ROW cur=mysql_fetch_row(result);
if (cur)
{
tee_fprintf(stdout, "Current database:\t%s\n", cur[0] ? cur[0] : "");
tee_fprintf(stdout, "Current user:\t\t%s\n", cur[1]);
}
mysql_free_result(result);
}
主要就是显示为红的地方
