What does " > sql.txt && sql -h-1 -i sql.txt && del sql.txt" commands mean?

Question

I am debugging some code that builds a SQL command which runs successfully.

However at the end of the query it looks as if the results of the query are written to a text file.

The full query is below

echo SELECT DATE,DATETABLE,DATE,APPDATE FROM CTD_ADF WHERE DATE IN (20130911) > sql.txt && sql   -h-1 -i sql.txt   && del sql.txt   

I assume the > sql.text is basically saying create and write the results to a text file called sql.text?

And, at the end && del sql.txt deletes the sql.text file at the end of execution?

But what does the && sql -h-1 -i sql.txt commands do / mean?

I've tried researching the -h-1 -i commands but so far have not managed to find an answer.

Answer 1

This is like using SQLCMD

-h -1 suppresses the column headers, and -i specify the input file, which is sql.txt

You can further check the syntax of sqlcmd Utility see if this is the case.
