All SQL DB statements need a sql.DB connection:
var conn *sql.DB = ...
defer conn.Close()
statement, err := conn.Prepare(SQL)
My question is, if I want to reuse the `conn` variable later on in the same
function,
conn, err = sql.Open("mssql", NewConnString)
Do I need to put another `defer conn.Close()` after it, or the first `defer
conn.Close()` still applies? Or I should call `conn.Close()` explicitly
beforehand?
thanks
