Shridhar,

can You show some lines from the top that we know the structure
A solution can be to create a DBF from the CSV-file and next using -> DBFTOARRAY

Hi Uwe ,

the .CSV file format will be similar as given below, it is simply invoice data. it has three segments 1) header 2) detail 3) footer.

Code: Select all  Expand view  RUN

H,ABC CO.,08052019, INV00031
D,10210,CROCIN TAB , 10, 30.00, 300, 10.00,10.00,320.00
D,21205,AMLOX TAB  , 10, 20.00, 300, 10.00,10.00,220.00
D,21535,CFLOX TAB  , 10, 10.00, 300, 10.00,10.00,120.00
F,30,30,660.00

 

Thanks
Shridhar

Does it mean that You need a array from the data-area ?
because a defined header and footer is not a normal CSV-file-structure
created from a DBF

Code: Select all  Expand view  RUN

aData := { { 10210,CROCIN TAB , 10, 30.00, 300, 10.00,10.00,320.00 }, ;
           { 21205,AMLOX TAB  , 10, 20.00, 300, 10.00,10.00,220.00 }, ;
           { 21535,CFLOX TAB  , 10, 10.00, 300, 10.00,10.00,120.00 } }

Hi Uwe ,

Need 3 different arrays to process invoice data into our database.

Looking for a function which returns an array (single dim) for each record during .CSV line read then I can copy /add record into relevant main array

Thanks

Code: Select all  Expand view  RUN

aData := HB_ATokens( cCsv, CRLF )
AEval( aData, { |c,i| aData[ i ] := HB_ATokens( c, "," ) } )
 

All elements of the array are untrimmed character values. You need to convert them into the required data type yourself.

Dear Rao Sir ,

Simple and Excellent solution ...! Thanks a lot ...!

Just one question on the variable cCsv ,

Shall I use below method to read entire .CSV file and copy data into cCsv variable or any other function/logic ? please guide for the same.

Code: Select all  Expand view  RUN

local cCSVFile := "purcbill.csv"
local cCsv

oFile  := TTxtFile():New( cCSVFile )
oFile:GoTop()
Do while !oFile:Eof()
    cCsv := cCsv  + oFile:ReadLine()
    oFile:Skip()
Enddo


aData := HB_ATokens( cCsv, CRLF )
AEval( aData, { |c,i| aData[ i ] := HB_ATokens( c, "," ) } )

 

Thanks
Shridhar

local cCSVFile := "purcbill.csv"
local cCsv

oFile := TTxtFile():New( cCSVFile )
oFile:GoTop()
Do while !oFile:Eof()
cCsv := cCsv + oFile:ReadLine()
oFile:Skip()
Enddo

Instead of the above six lines of code,

Code: Select all  Expand view  RUN

cCsv := MEMOREAD( cCsvFile )
