# Configuración especial

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

Para acceder a esta orden…

En la ventana de una base de datos, elija Editar ▸ Base de datos ▸ Configuración avanzada

La disponibilidad de los controles siguientes depende del tipo de base de datos:

## Utilizar restricciones de nomenclatura 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.

## Append the table alias name in SELECT statements

Appends the alias to the table name in SELECT statements.

## Use keyword AS before table alias names

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.

## Use Outer Join syntax '{OJ }'

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

Ejemplo:

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

## Ignore the privileges from the database driver

Ignores access privileges that are provided by the database driver.

## Replace named parameters with ?

Replaces named parameters in a data source with a question mark (?).

## Display version columns (when available)

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

Permite utilizar el nombre del esquema en instrucciones SELECT.

## Create index with ASC or DESC statement

Crea un índice con instrucciones ASC o DESC.

## End text lines with CR + LF

Select to use the CR + LF code pair to end every text line (preferred for DOS and Windows operating systems).

## Ignorar información de campo monetario

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.

## Form data input checks for required fields

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.

El cuadro de control está disponible para todos los tipos de orígenes de datos compatibles con el acceso de escritura a los datos, pero no para hojas de cálculo, archivos de texto, archivos CSV y libretas de direcciones de solo lectura.

## Use ODBC conformant date/time literals

Use date/time literals that conform to ODBC standard.

## Admite claves principales

Active esta opción para dejar sin efecto la heurística de Base que detecta si la base de datos admite claves principales.

Al conectarse con una base de datos mediante una API genérica como ODBC, JDBC o ADO, Base aplica heurísticas para determinar si esa base de datos admite las claves principales. Ninguna de las API mencionadas incluye un método directo para obtener esta información.

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.

Tenga en cuenta que esta opción es únicamente para anular la heurística. Si activa la casilla para una base de datos que no admite claves principales, se producirán errores.

## Respetar tipo de conjunto de resultados del controlador de base de datos

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

## Comparación de valores booleanos

Seleccione el tipo de comparación booleana que desee utilizar.

## Filas para analizar tipos de columnas

Seleccione el número de filas para permitir que el controlador detecte el tipo de datos.
