/**
 * Creates the <kbd>phptest</kbd> table
 *
 * Tries to drop the table first, in case it already exists.
 *
 * <pre>
 * CREATE TABLE phptest (
 *   a INTEGER NULL,
 *   b CHAR(40) DEFAULT 'def' NOT NULL,
 *   cc VARCHAR(255) NULL,
 *   d VARCHAR(20) NULL)
 * </pre>
 *
 * Need <kbd>NOT NULL</kbd> on <kbd>b</kbd> to test
 * <kbd>DB_PORTABILITY_RTRIM</kbd>.  MS SQL and Sybase trim output from
 * <kbd>VARCHAR</kbd>, but not on <kbd>CHAR</kbd>.
 *
 * Need <kbd>DEFAULT</kbd> value on <kbd>b</kbd> because Oracle considers
 * an empty string to be <kbd>NULL</kbd>.
 *
 * In Oracle, when using placeholders in <kbd>WHERE</kbd> clauses on 
 * <kbd>CHAR</kbd> columns, the column must have <kbd>RTRIM()</kbd> run on
 * the column:
 * <samp>
 *    SELECT * FROM phptest WHERE RTRIM(b) = ?
 * </samp>
