You have an error in your SQL syntax;near 'exec print_pack.check_print ?, ?'

Anyone know where I am going wrong here:
EXEC('IF EXEC
sp_executesql N''' +@command+ ' = '' '' '' PRINT ''' +@DB_Name+
'''')
The error says the following
Incorrect syntax near the
keyword 'EXEC'.
Msg 170, Level 15, State 1, Line 2
Line 2:
Incorrect syntax near ' '.
Thanks

I have this line of SQL:

$sql = "SELECT ID, ListStID, ListEmail, Title FROM

$entry_database WHERE ID = '". $ReqBookID ."'";

$result = mysqli_query($conn, $sql);

As you can see, I am selecting an entry's ID, ListStID, ListEmail
and Title Column if ID is equal to a string of numbers (or text),
which is given by user in a form.

Everything is ok, and I don't get any syntax error when I write the
code (I am using a code editor software. However, when I use it
online, I get this error:

Error: SELECT ID, ListStID, ListEmail, Title FROM WHERE ID = '4'

I am very new to PHP, and I'm sure I am either adding extra ' or ",
so I would really appreciate it if you could help me with this issue.
I have tried the answers for similar questions, but no success
yet.
