示例1: getFieldSQL
/**
* Given one correct xmldb_field, returns the complete SQL line to create it.
*
* @param xmldb_table $xmldb_table The table related to $xmldb_field.
* @param xmldb_field $xmldb_field The instance of xmldb_field to create the SQL from.
* @param string $skip_type_clause The type clause on alter columns, NULL by default.
* @param string $skip_default_clause The default clause on alter columns, NULL by default.
* @param string $skip_notnull_clause The null/notnull clause on alter columns, NULL by default.
* @param string $specify_nulls_clause To force a specific null clause, NULL by default.
* @param bool $specify_field_name Flag to specify fieldname in return.
* @return string The field generating SQL statement.
* @throws coding_exception Thrown when xmldb_field doesn't validate with the xmldb_table.
