Work with Adobe Target Data in FoxPro



Load Adobe Target data into a FoxPro database. This article includes full code and a walk-through of the process.

The CData ODBC driver for Adobe Target enables you to access Adobe Target data using the ODBC standard. You can use the CData ODBC Driver for Adobe Target to integrate Adobe Target data into your FoxPro project. The procedure below provides a walk-through of the included code sample, which saves Adobe Target data into tables in a FoxPro database.

Connect to Adobe Target as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

NOTE: Set the 'Map To WVarchar' connection property to FALSE (FoxPro uses the ODBC W API and returns the WCHAR for the value type).

To connect to Adobe Target, you must provide the Tenant property along with OAuth connection properties mentioned below. Note that while other connection properties can influence processing behavior, they do not affect the ability to connect.

To determine your Tenant name:

  1. Log in to Adobe Experience. The URL will look similar to: "https://experience.adobe.com/#/@mycompanyname/preferences/general-section".
  2. Extract the value after the "/#/@". In this example, it is "mycompanyname".
  3. Set the Tenant connection property to that value.

User Accounts (OAuth)

You must set AuthScheme to OAuthClient for all user account flows.

Note: Adobe authentication via OAuth requires updating your token every two weeks.

All Applications

CData provides an embedded OAuth application that simplifies OAuth authentication. Alternatively, you can create a custom OAuth application. Review Creating a Custom OAuth App in the Help documentation for more information.

Obtaining the OAuth Access Token

Set the following properties to connect:

  • InitiateOAuth: Set to GETANDREFRESH to automatically perform the OAuth exchange and refresh the OAuthAccessToken as needed.
  • OAuthClientId : Set to the client Id assigned when you registered your app.
  • OAuthClientSecret : Set to the client secret assigned when you registered your app.
  • CallbackURL : Set to the redirect URI defined when you registered your app. For example: https://localhost:3333

With these settings, the provider obtains an access token from Adobe Target, which it uses to request data. The OAuth values are stored in the location specified by OAuthSettingsLocation, ensuring they persist across connections.

Connect and Transfer

To get started, add the code sample to a new project. You can execute the following command to save all tables without displaying them:

DO C:\Temp\sqldump.prg WITH "CData AdobeTarget Source", "TESTDB", .f.

Below is the process that the program follows:

  1. Create a new FoxPro database.
  2. Open a connection to Adobe Target data with the line below:

    m.hSQLconnection = SQLCONNECT(m.cODBCDSN)
    
  3. If the connection was successful, you can now retrieve the list of tables using the SQLTABLES function. The code below saves the list of tables in sys_tables.dbf:

    WAIT WINDOW "Fetching tables for data source '" + m.cODBCDSN + "'..." NOWAIT NOCLEAR
    m.nSQLTABLES = SQLTABLES(m.hSQLconnection)
    
    IF lUseDistinctConnections
      WAIT WINDOW "Closing ODBC Connection for data source '" + m.cODBCDSN + "'..." NOWAIT NOCLEAR
      SQLDISCONNECT(m.hSQLconnection)
      m.hSQLconnection = 0 * SQLCONNECT needs to be called again
    ENDIF
    
    IF m.nSQLTABLES > 0
      * create local table containing list of tables in db
      COPY TO (m.cImportData + "sys_tables")
      USE
    
      * convert each table to DBF
      USE (m.cImportData + "sys_tables")
      ALTER TABLE DBF("sys_tables") ;
      ADD COLUMN records i ;
      ADD COLUMN dbfname m
    
  4. Scan over each table, saving it to a DBF file. The function ODBCtoDBF stores the table in a DBF file and then opens a grid if the lBrowse parameter is set to true:
    FUNCTION ODBCtoDBF (cTableName as String, cTableType as String, lBrowse as Logical, lhSQLConnection as Integer)
    
      WAIT WINDOW ;
      "Converting " + m.cTableType + ' "' + m.cTableName + '" to DBF...' ;
      NOWAIT NOCLEAR
    
      ACTIVATE SCREEN
    
      * strip characters incompatible with FoxPro out of the name of the DBF file
      m.cTableAlias		= ""
      m.nTableNameLen		= LEN(m.cTableName)
      m.nTableNameStart	= 1
      
      FOR m.nTableNameStart = 1 TO m.nTableNameLen
        m.cCharacter = SUBSTR(m.cTableName, m.nTableNameStart, 1)	
        IF !ISALPHA(m.cCharacter) .and. (m.nTableNameStart = 1 .or. !ISDIGIT(m.cCharacter))
          m.cTableAlias = m.cTableAlias + "_"
        ELSE
          m.cTableAlias = m.cTableAlias + m.cCharacter
        ENDIF
      ENDFOR
    
      m.cFromTable = m.cTableName
      m.cTempViewAlias	= m.cTableType + "_" + m.cTableAlias
    
      LOCAL loException as Exception
      LOCAL lnResultSets
      
      TRY
        * run query
        m.lnResultSets = SQLEXEC(m.lhSQLConnection, ;
          "SELECT * FROM " + m.cFromTable, ;
          m.cTempViewAlias, ;
          aSQLResult)
    	  
        IF m.lnResultSets#1
          SET STEP ON
        ENDIF
    	
        ACTIVATE SCREEN
    
      CATCH TO m.loException
        ACTIVATE SCREEN
        ? "Error opening " + m.cTempViewAlias + ":"
        ? m.loException.Message
        ? m.loException.Details
      ENDTRY
    
      IF !USED(m.cTempViewAlias)
        RETURN
      ENDIF
    
      * copy records from view cursor to disk
      SELECT * FROM (m.cTempViewAlias) ;
        INTO TABLE (m.cImportData + m.cTableAlias)
    
      IF USED(m.cTableAlias)
    
        ACTIVATE SCREEN
    
        FLUSH	&& flush the buffer to write the data to disk
    
        IF m.lBrowse
          * pop the table up on screen
          SELECT (m.cTableAlias)
          BROWSE NORMAL NOMODIFY NOWAIT
          ACTIVATE SCREEN
        ELSE
          * close on-disk table for now
          USE IN (m.cTableAlias)
          ACTIVATE SCREEN
        ENDIF
      ENDIF
    
      IF USED(m.cTempViewAlias)
        USE IN &cTempViewAlias && close SQL view
        ACTIVATE SCREEN
      ENDIF
    
      WAIT CLEAR
    
    ENDFUNC
    
  5. You can now save tables of Adobe Target data as DBF files.

Below is the full code, in FoxPro 9 syntax:

PARAMETERS cODBCDSN, cDatabaseName, lBrowseAfterConvert

*	cODBCDSN				The ODBC data source name, used for the name of the folder where the DBF tables are stored.
*	cDatabaseName			The name of the FoxPro database to use. This database is created if it does not exist. The default is DATABASE_NAME.
*								
*	lBrowseAfterConvert		If ".t." display each table with the BROWSE command after importing it. If ".f." close each table before moving on to the next one.
