Attribute

SchemaMap (SMP)

Purpose

Specifies either the name or the absolute path and name of the configuration file where the relational map of native data is written. The driver looks for this file when connecting to a Google BigQuery instance. If the file does not exist, the driver creates one.

Valid Values

string

where:

string
is either the name or the absolute path and name (including the .config extension) of the configuration file. For example, if Schema Map is set to a value of:
  • ABC, the driver either creates or looks for the configuration file ABC in the working directory of your application.
  • C:\Users\Default\AppData\Local\Progress\DataDirect\GoogleBigQuery_Schema\jsmith@defcorp.config, the driver either creates or looks for the configuration file jsmith@defcorp.config in the directory C:\Users\Default\AppData\Local\Progress\DataDirect\GoogleBigQuery_Schema.

Notes

  • When connecting to a Google BigQuery instance, the driver looks for the schema map configuration file. If the configuration file does not exist, the driver creates a schema map using the name and location you have provided. If you do not provide a name and location, the driver creates one using default values.
  • The driver uses the path specified in this connection option to store additional internal files.
  • You can refresh the internal files related to an existing view of your data by using the SQL extension Refresh Map. Refresh Map runs a discovery against your native data and updates your internal files accordingly.

Default

The default is determined by the environment. The driver attempts to create the files in a subdirectory of the first available directory in the following order:

  • Windows
    • DD_HOME environment variable
    • LOCALAPPDATA environment variable
    • APPDATA environment variable
    • User’s home directory
    For Windows, the file path takes the following format: 
    available_location\Progress\DataDirect\GoogleBigQuery_Schema\user_name.config
  • UNIX/Linux
    • DD_HOME environment variable
    • User’s home directory
    For UNIX/Linux, the file path takes the following format: 
    available_location/progress/datadirect/GoogleBigQuery_schema/user_name.config
