SCALA : Scala code to Call Data from Oracle Data Source and Convert them to CSV files

 Hi All,

Below is the code which is used to run the query from Oracle Database and load them to CSV files using Scala.


object Main {

 

  def main(args: Array[String]): Unit = {

 

    /* Local connection details*/

    val dbUser = "dbusernameo"

    val dbPassword = "dbpassword"

    val dbURL = "jdbc:oracle:thin:@11.2.4.80:1234:databasename"

 

    val configQuery =

      """

      SELECT First_Name,Last_Name,Middle_Name,Student_Number

      ,Grade_Level,Enroll_Status,Gender

      from Students Where rownum<2

        """

    val conConfig = OracleConnect.connJdbc(dbUser, dbPassword, dbURL)

 

    val statement = conConfig.createStatement()

    statement.setFetchSize(1000)

    val resultSet: java.sql.ResultSet = statement.executeQuery(configQuery)

 

    /* Read all the variable from Orcale table*/

    while (resultSet.next) {

     // var oracleURL = resultSet.getString("First_Name")

     // var oracleUser = resultSet.getString("Last_Name")

      //var oraclePassword = resultSet.getString("Middle_Name")

      //var oracleOutPutFilePath = resultSet.getString("Student_Number")

      //var oracleOutPutFileDateFormat = resultSet.getString("Student_Number")

     // var oracleQueryFilePath = resultSet.getString("Grade_Level")

 

      //val Enroll_Status = resultSet.getString("Enroll_Status")

      //val Gender = resultSet.getString("Gender")

 

      oracleURL = "jdbc:oracle:thin:@11.2.4.80:1234:databasename "

      oracleUser = " dbusernameo "

      oraclePassword = "dbpassword"

      oracleOutPutFilePath = "C:\\Scala\\student.csv"

      oracleOutPutFileDateFormat = "yyyyMMdd"

      oracleQueryFilePath = "C:\\Scala\\Config\\sampleQuery.txt"

 

      /* Call CSV export function*/

      CSVExport.exportCSVFile(oracleUser, oraclePassword, oracleURL, oracleOutPutFilePath, oracleOutPutFileDateFormat, oracleQueryFilePath)

    }

 

  }

 

}

BIG Data, Hadoop – Chapter 2 - Data Life Cycle

Data Life Cycle The data life cycle is pictorial defined as show below:     As we see, in our current system, we capture/ Extract our data, then we store it and later we process for reporting and analytics. But in case of big data, the problem lies in storing and then processing it faster. Hence Hadoop takes this portion, where it stores the data in effective format (Hadoop distributed File System) and also process using its engine (Map Reduce Engine). Since Map Reduce engine or Hadoop engine need data on HDFS format to process, We have favorable tools available in market to do this operation. As an example, Scoop is a tool which converts RDBMS to HDFS. Likewise we have SAP BOD to convert sap system data to HDFS.

How to Copy or Move Multiple Files from One Folder to Another Folder using Talend

Hello all, In this Post, I will explain how to move Multiple Files from One Folder (Say Source) to Other folder (Say Destination). This Post will also helps you to understand How to Declare Variable and Use it. To Declare a variable, We are go to use Contexts option in repository. Lets say we have two .txt files in Path D:/Source/ . My Requirement is to move the files from Source Folder ( D:/Source/ ) to Destination Folder ( D:/Dest/ ). Step 1: Open a New job Step 2: Now right click and Create a New Contexts from Repository. Give some Name and give Next. Step 3: Now Fill in the Source Directory Details where the loop on files should happen as shown in the snippet and give finish. Step 4: Now Context is created and The values will be changing based on each file in Folder. Step 5: Click and Drag the context from Repository to Context Job Window below the Job Designer. Step 6: If we Expand the Contexts, We can find the variable SourcePath is holdi...

Solution : PyMSSql - import _mssql - ImportError: DLL load failed: The specific module could not be found

When you install pymssql module using pip in python and then try to import pymssql, you may end up with “ PyMSSql - import _mssql - ImportError: DLL load failed: The specific module could not be found ” error, if you are using pymssql version 2.1 or greater. This is due to security reason, pymssql now is not linked with SSL and FreeTDS, unlike previous version where SSL and FreeTDS were jointly linked with pymssql during installation. This information can be found on pymssql site found http://pymssql.org/en/latest/freetds.html#windows In order to overcome, we need to install supporting components FreeTDS and OpenSSL independently and then pymssql will work without any issue. Below are the steps to download and configure FreeTDS and OpenSSL. FreeTDS can be downloaded https://github.com/ramiro/freetds/releases And extract the file which is download. Now place the extract folder where your python module is installed.  (Can be kept anywhere but to avoid accide...
