Description
The CREATE GATEWAY command is used to create a gateway file to an external SQL database table. See Supported Data Sources for the SQL Databases that can be accessed on each individual platform.
The GATEWAY method allows SQL database tables to be accessed via the Recital forms interface. This requires the creation of a gateway file and an empty Recital table that has a structure matching that of the external file. By convention, the empty structure file is given the file extension '.str' rather than the default '.dbf'. SQL Databases can also be accessed directly using Passthrough SQL. For more information on Recital/SQL capabilities, please see the Recital/SQL documentation.
The CREATE GATEWAY worksurface provides a full screen facility for gateway creation in Recital Terminal Developer. The <.gtw filename> can be substituted with any character expression, enclosed in round brackets, that returns a valid filename. If no file extension is specified, then .gtw is used. The following elements can be defined for the gateway:
| Server Element | Description |
|---|---|
| Name | The remote server name, e.g. Oracle |
| Network Node Name | The node name or IP address of the server |
| Protocol Type | The connection protocol, DECNET or TCP/IP |
| Login Username | The login for the server |
| Login Password | The login password for the server |
| Database Name | The full name (including path if applicable) of the database |
| Table Name | The table name from the database |
| Table Primary Key | The primary index key for the table |
| Table Restriction | An optional SQL SELECT…WHERE clause |
| Client Element | Description |
|---|---|
| Structure Name | The name of the matching Recital structure table |
| Alias Name | The alias name for the client table |
| Default Form Name | The default screen form to be used |
