# Special Settings

Specifies the way you can work with data in a database.

Доступ к этой команде

In a database window, choose Edit - Database - Advanced Settings

The availability of the following controls depends on the type of database:

## Использовать ограничения SQL92

Only allows characters that conform to the SQL92 naming convention in a name in a data source. All other characters are rejected. Each name must begin with a lowercase letter, an uppercase letter, or an underscore ( _ ). The remaining characters can be ASCII letters, numbers, and underscores.

## Добавить псевдоним таблицы в запрос SELECT

Добавляет псевдоним таблицы в инструкцию SELECT.

## Использовать ключевое слово AS

Some databases use the keyword "AS" between a name and its alias, while other databases use a whitespace. Enable this option to insert AS before the alias.

## Использовать синтаксис внешнего объединения «{OJ }»

Use escape sequences for outer joins. The syntax for this escape sequence is {oj outer-join}

Пример:

select Article.* from {oj item LEFT OUTER JOIN orders ON item.no=orders.ANR}

## Игнорировать привилегии из драйвера базы данных

Игнорирует привилегии доступа, предоставляемые драйвером базы данных.

## Заменять именованные параметры на «?»

Заменяет именованные параметры в источнике данных знаком вопроса (?).

## Отобразить столбцы версии (если доступны)

Some databases assign version numbers to fields to track changes to records. The version number of a field is incremented by one each time the contents of the field are changed. Displays the internal version number of the record in the database table.

## Use the catalog name in SELECT statements

Uses the current data source of the catalog. This option is useful when the ODBC data source is a database server. Do not select this option if the ODBC data source is a dBASE driver.

## Use the schema name in SELECT statements

Allows you to use the schema name in SELECT statements.

## Создать индекс с условиями ASC или DESC

Создаёт индекс с условиями ASC или DESC.

## Заканчивать текст CR+LF

Выберите, чтобы завершать каждую текстовую строку парой кодов CR + LF (предпочтительно для DOS и Windows).

## Игнорировать информацию валютных полей

Only for Oracle JDBC connections. When enabled it specifies that no column is treated as a currency field. The field type returned from the database driver is discarded.

## Форма проверяет требуемые поля

When you enter a new record or update an existing record in a form, and you leave a field empty which is bound to a database column which requires input, then you will see a message complaining about the empty field.

If this control box is not enabled, then the forms in the current database will not be checked for required fields.

The control box is available for all data source types which support write access to their data. The control box does not exist for spreadsheets, text, csv, and the various read-only address books.

## Использовать ODBC-совместимый формат даты/времени

Использовать литералы даты и времени, соответствующие стандарту ODBC.

## Поддерживаются первичные ключи

Enable to overrule Base's heuristics used to detect whether the database supports primary keys.

When connecting to a database using a generic API like ODBC, JDBC, or ADO, Base currently applies heuristics to determine whether this database supports primary keys. None of those APIs has dedicated support to retrieve this information.

The heuristics sometimes fails. This tri-state check box by default is set to the undetermined state, which means "apply the heuristics". If the check box is enabled, primary key support is assumed. If the check box is disabled, no primary key support is assumed.

Note that if this option is just for overruling the heuristics. If you enable the check box for a database which actually does not support primary keys, you will see some errors.

## Тип результирующего набора из драйвера базы данных

Use the database driver different scroll capabilities of a result set. Refer to ResultSetType Constant Group

## Сравнение логических значений

Выберите тип логического сравнения, который хотите использовать.

## Rows to scan columns types

Select the number of rows to let the driver detect the data type.
