Work with Jira Data in FoxPro

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

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

About Jira Data Integration

CData simplifies access and integration of live Jira data. Our customers leverage CData connectivity to:

  • Gain bi-directional access to their Jira objects like issues, projects, and workflows.
  • Use SQL stored procedures to perform functional actions like changing issues status, creating custom fields, download or uploading an attachment, modifying or retrieving time tracking settings, and more.
  • Authenticate securely using a variety of methods, including username and password, OAuth, personal access token, API token, Crowd or OKTA SSO, LDAP, and more.

Most users leverage CData solutions to integrate Jira data with their database or data warehouse, whether that's using CData Sync directly or relying on CData's compatibility with platforms like SSIS or Azure Data Factory. Others are looking to get analytics and reporting on live Jira data from preferred analytics tools like Tableau and Power BI.

Getting Started


Connect to Jira 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 JIRA, provide the User and Password. Additionally, provide the Url; for example, https://yoursitename.atlassian.net.

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 JIRA Source", "TESTDB", .f.

Below is the process that the program follows:

  1. Create a new FoxPro database.
  2. Open a connection to Jira 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 Jira 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.
