Please make a little effort to attach the representation code (not screenshot)?

When you vertically concatenate A and B the number of columns in A and B must match. In your case, they do not. That's the best answer you'll get with the limited data you've shared.

Could it be that your variable strHH is not a row vector char array?

I find it useful to define sql statement in a separate literal with a string column vector, so you can read it clearly but without all the ... continuations

sql = ["select * "

"from dual "

"order by dummy"]

sql = join(sql, newline)

exec(conn, sql, ...
