To execute either flavor of command when that command contains dynamic
parameters, taking values from the Using portion of the command. In this style,
the Using portion's String or previously prepared Identifier is executed, and it must have a result set
as its result. Each row of the result set is applied to the input parameters
of the command to be executed, so the number of columns in the Using's
result set must match the number of input parameters in the Execute's statement. The results of each execution of the Execute statement are displayed as they are made. If the Using's
result set contains no rows, the Execute's
statement is not executed.
When auto-commit mode is on, the Using's
result set is closed upon the first execution of the Execute statement. To ensure multiple-row execution of the Execute command, use the Autocommit command
to turn auto-commit off.
