Application to import 12 Datasets along with 43 tables dynamically by using LOAD DATA command which loads data from a source into an IRIS SQL table.
List of Datasets

Features

Dynamically creation of table based on the CSV file data.
Import dataset by using LOAD DATA functionality by Terminal or by web application.
Remove dataset programmatically by terminal or by Web Application.
Dynamically view Imported Data from Web Application.
Functionality to Import data into CSV, Excel or PDF Format.
Responsive web application to view the status of Dataset.
Any or All datasets can be install or Remove with single command.
Use of %SQL_Diag.Result and %SQL_Diag.Message tables with LOAD DATA

It is recommended to read related documentations LOAD DATA (SQL).

How to install or remove any Dataset from Terminal

Use below command to import particular Dataset by passing it's ID or pass 999 to import all DataSets

do ##class(dc.data.medical.utility).ImportDS(1)

Below is the main script to create table dynamically and load data by using LOAD DATA functionality. Please note that table is created dynamically

//Get file name 
SET filename=tRS.Get("Name")
//Remove .csv from the file name
SET tableName=$REPLACE("dc_data_"_ds_"."_tRS.Get("ItemName"),".csv","") 
//Get columns based on the header row of csv file
Do ##class(dc.data.medical.utility).GetColTypes(filename,.coltype) 
//Dynamically create table based on tablename and column types
SET qry = "CREATE TABLE "_tableName_" ("_coltype_")"
SET rset = ##class(%SQL.Statement).%ExecDirect(,qry)
//Check if table created successfully
IF rset.%SQLCODE
{
   WRITE "ERROR : ",rset.%Message,!    
}
ELSE
{
  //Dynamically construct LOAD DATA statement
  SET qry = "LOAD DATA FROM FILE &nbsp;'"_filename_"' INTO "_tableName_ " "_"USING {""from"":{""file"":{""header"":""1""}}}"
  SET rset = ##class(%SQL.Statement).%ExecDirect(,qry)
  // Check result set sqlcode, In case of error write resultset message
  IF rset.%SQLCODE
  {
 &nbsp; WRITE "ERROR Table : " _tableName_" IMPORT FAILED: ",rset.%Message,!
  }
  ELSE
  {
&nbsp; WRITE "SUCCESS table : " _tableName_" created and "_rset.%ROWCOUNT_" Rows Imported Successfully",!
  }
}

Use below command to remove particular Dataset by passing it's ID or pass 999 to remove all DataSets

do ##class(dc.data.medical.utility).RemoveDS(1)

Below is the main script to remove table dynamically

//Get file name
SET filename=tRS.Get("Name")
//Remove .csv from file name
SET tableName=$REPLACE("dc_data_"_ds_"."_tRS.Get("ItemName"),".csv","")
//Drop table
SET qry = "DROP TABLE "_tableName
SET rset = ##class(%SQL.Statement).%ExecDirect(,qry)
//Check if table deleted successfully
IF rset.%SQLCODE
{
  WRITE "ERROR : ",rset.%Message,!          
}
ELSE
{
  WRITE "Table "_tableName_" deleted successfully",!
}
