Borland paradox odbc memory reported by Windows because of the swap file should not be included when using this formula. A general guideline is to set this value to a number that is between one half to two thirds the amount of electronic memory on the computer. It defaults to two megabytes or a value of This setting is more critical than MinBufSize in terms of the impact it can have on performance. ODBC Driver for Paradox 7 tables - delphi.Assuming there is an adequate amount of memory, MaxBufSize is the setting that determines the maximum size obtainable by the table buffer. While MinBufSize borland paradox odbc the immediate size of the table buffer, the table buffer can grow in size as more and more table data is read. This will mean that two megabytes will be reserved for the table buffer as soon as the BDE borland paradox odbc loaded. Given that most computers these days have eight to sixteen megabytes of electronic memory, it is generally beneficial to change this setting to at least two megabytes or as a value borland paradox odbc the MinBufSize setting on the system tab of the BDE Configuration Utility. The script is freely available on GitHub as a simple Gist. Paradox Driver Programming ConsiderationsДЄctive 3 years, 9 months ago. Reading Paradox Database files Ask Question. To set this option dynamically, use the PARADOXUSERNAME keyword in a call to SQLConfigDataSource.EXEas a Windows administrator when you make these changes. This is the name displayed to other users of Paradox files when a lock is encountered. To set this option dynamically, use the PARADOXNETPATH keyword in a call to SQLConfigDataSource. Click Select Network Directory to select a network directory. For information about these files, see the Paradox documentation.Д«efore you can select a network directory, you must enter your Paradox user name in the User Name text box.

The full path of the directory containing a Paradox lock database, because it contains either the file (in Paradox 4. Or, you can specify a new default directory by using the SQLSetConnectOption function with the SQL_CURRENT_QUALIFIER option. Alternatively, you can qualify file names in a SELECT statement with the directory name: Copy other files into this directory if they are used frequently. The ODBC driver uses this directory as the default directory. When defining a data source directory specify the directory where your most commonly used files are located. To set this option dynamically, use the READONLY keyword in a call to SQLConfigDataSource.Дisplays a dialog box where you can select a directory containing the files you want to access. To set this option dynamically, use the PAGETIMEOUT keyword in a call to SQLConfigDataSource. The page timeout cannot be less than the inherent delay, even if the page timeout option is set below that value. The page timeout cannot be 0 because of an inherent delay.

This option applies to all data sources that use the ODBC driver. The default is 600 tenths of a second (60 seconds).

Specifies the period of time, in tenths of a second, that a page (if not used) remains in the buffer before being removed. To set this option dynamically, use the PARADOXNETSTYLE keyword in a call to SQLConfigDataSource. The network access style to use when accessing Paradox data: either '3. To set this option dynamically, use the EXCLUSIVE keyword in a call to SQLConfigDataSource. Performance is enhanced when running in Exclusive mode. If the Exclusive box is selected, the database will be opened in Exclusive mode and can be accessed by only one user at a time.

To set this option dynamically, use the DESCRIPTION keyword in a call to SQLConfigDataSource. To set this option dynamically, use the COLLATINGSEQUENCE keyword in a call to SQLConfigDataSource.ДЄn optional description of the data in the data source for example, 'Hire date, salary history, and current review of all employees.' The sequence can be ASCII (the default), International, Swedish-Finnish, or Norwegian-Danish. The sequence in which the fields are sorted. To set this option dynamically, use the DEFAULTDIR keyword in a call to SQLConfigDataSource. Setting Options Programmatically for the Paradox Driver
