Import CSV files

As you have seen the Exporting Complete Table Record into CSV in the last post. Same way here i have written Code for Importing CSV into Table

static void Import_CSV(Args _args)
{
common TableBuffer;
DictTable dictTable = new DictTable(tableNum(TableName)); // Define Table Name
str TableName = dictTable.name();
DictField dictField;
int i;
CommaIo file;
container line;
str path = 'C:\\Users\\saadullah\\Documents\\'+TableName+'.csv'; // Directory Path
#define.filename(path)
#File
file = new CommaIo(#filename, #io_read);
if (!file || file.status() != IO_Status::Ok)
 {
 throw error("File cannot be opened.");
 }
TableBuffer = dictTable.makeRecord();
while (file.status() == IO_Status::Ok)
 {
 line = file.read(); // Selecting File values line by line as assigning to Container
 if (line != conNull())
 {
 // Looping the Table Field
 // we have Defined - 15 from the Counting of Fields 
 // we do not Require 15 System Field such as RecId, RecVersion, Created By, Created Datetime, Modified By, etc...
 for( i =1; i <= dictTable.fieldCnt() -15; i++)
 {
 // Selecting the Fields
 dictField = new DictField(dictTable.id(), dictTable.fieldCnt2Id(i));
 // Assigning the Container values to the Selected Table Field
 TableBuffer.(dictField.id()) = conpeek(line, i);
 }
 // Inserting Record 
 TableBuffer.doInsert();
 }
 }
}

Export CSV file

Hi Guys,.

Today i’m going to share one of the easiest way to Export and Import the Data without Microsoft Office Excel.
Its Comma Separated Value (CSV). The main Objective of CSV is storing the table record in the CSV file. even though i have found it from CookBook. But i have modified that coding for General Purpose in any table we can easily Export and Import.
Here i have written my Job for Exporting Complete data of any defined Table into CSV..

static void ExportCSV(Args _args)
 {
 common TableBuffer;
 DictTable dictTable = new DictTable(tableNum(TableName)); // Define Table Name
 str TableName = dictTable.name();
 DictField dictField;
 int i;
 CommaIo file;
 container line;
 str path = 'C:\\Users\\saadullah\\Documents\\'+TableName+'.csv'; // Directory Path
 #define.filename(path)
 #File
file = new CommaIo(#filename, #io_write);
if (!file || file.status() != IO_Status::Ok)
 {
 throw error("File cannot be opened.");
 }
TableBuffer = dictTable.makeRecord();
// Select the Entire Table
 while select TableBuffer
 {
 // Looping the Table Field
 // we have Defined - 15 from the Counting of Fields
 // we do not Require 15 System Field such as RecId, RecVersion, Created By, Created Datetime, Modified By, etc...
 for( i =1; i <= dictTable.fieldCnt() -15; i++)
 {
 // Selecting the Fields
 dictField = new DictField(dictTable.id(), dictTable.fieldCnt2Id(i));
// Adding the Selected Field values in Container
 line += [ TableBuffer.(dictField.id()) ];
}
 // Wrting the Selected Container Expression in File
 file.writeExp(line);
// we have to store the Next Records , so we are making Container to Null
 line = ConNull();
 }
info(strfmt("File Successfully Created in %1", #filename));
}
