/*
* B.1 Create table, insert, select
*
* This example function creates a table, inserts data into the table,
* and selects the inserted data.
*
* This example illustrates the execution of SQL statement text
* both using the Prepare() and Execute() method and using the
* ExecDirect() method. The example also illustrates both the case
* where the application uses the automatically-generated descriptors
* and the case where the application allocates a descriptor of its
* own and associates this descriptor with the SQL statement.
*
* Code comments include the equivalent statements in embedded SQL
* to show how embedded SQL operations correspond to SQL/CLI function
* calls.
