All columns must be bound to buffers prior to calling mysql_stmt_fetch().
address of an array of
element for each column of the result set. If you do not bind columns to
mysql_stmt_fetch()
data values, because the protocol doesn't return data values in chunks.
A column can be bound or rebound at any time, even after a result set has been partially retrieved.
The new binding takes effect the next time
application binds the columns in a result set and calls mysql_stmt_fetch(). The client/server
protocol returns data in the bound buffers. Then suppose that the application binds the columns to a
different set of buffers. The protocol places data into the newly bound buffers when the next call to
mysql_stmt_fetch()
To bind a column, an application calls
and length of the output buffer into which the value should be stored.

should be set to receive output values.
Return Values
Zero if the bind operation was successful. Nonzero if an error occurred.
