Specifies the way you can work with data in a database.
The availability of the following controls depends on the type of database:
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.
Appends the alias to the table name in SELECT statements.
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 escape sequences for outer joins. The syntax for this escape sequence is {oj outer-join}
Example:
select Article.* from {oj item LEFT OUTER JOIN orders ON item.no=orders.ANR}
Ignores access privileges that are provided by the database driver.
Replaces named parameters in a data source with a question mark (?).
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.
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.
Allows you to use the schema name in SELECT statements.
Creates an index with ASC or DESC statements.
Select to use the CR + LF code pair to end every text line (preferred for DOS and Windows operating systems).
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.
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.
Use date/time literals that conform to ODBC standard.
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.
Use the database driver different scroll capabilities of a result set. Refer to ResultSetType Constant Group
Select the type of Boolean comparison that you want to use.
Select the number of rows to let the driver detect the data type.
