I need to construct complex SQL request, like:
string sql = ("INSERT INTO test.geomagnetic (`date`,
`a_fredericksburg`, `fredericksburg`, `a_college`, `college`,
`a_planetary`, `planetary`) VALUES ('%s', '%s', '%s', '%s',
'%s', '%s', '%s');", date[i], a_fredericksburg[i],
fredericksburg[i], a_college[i], college[i], a_planetary[i],
planetary[i]);
I except that writefln have some behavior as string
concatenation, but it does not.
IS there any way to put needed values in place of %s in string?
Just FYI use prepared statements instead of string concatenation
for SQL queries.
