execute-one! (clj)
(source)function
(execute-one! stmt)
(execute-one! connectable sql-params)
(execute-one! connectable sql-params opts)
General SQL execution function that returns just the first row of a result.
For any DDL or SQL statement that will return just an update count, this is
the preferred function to use.
Can be called on a `PreparedStatement`, a `Connection`, or something that can
produce a `Connection` via a `DataSource`.
Note: although this only returns the first row of a result set, it does not
place any limit on the result of the SQL executed.
