ADO Connection and Recordset = ""

424 views Asked by At

Do CSV (comma delimited text files) have a sheet name? Do I need to specify a range for data to copy?

My SQL skills are weak.

I am trying to get all the text from my export.csv file into a worksheet where the "Price" column is not empty and sort it by "sku".

I can open the file and build the SQL string but there must be an error?

The debugger shows the string as:

"SELECT * FROM [export$] WHERE price IS NOT NULL ORDER BY sku;"

When I try and open the Connection and Recordset the debugger shoes they both contain the value of "".

Set rsCon = CreateObject("ADODB.Connection")
Set rsData = CreateObject("ADODB.Recordset")

When I get to using them I go straight to my error trap.

rsCon.Open szConnect
rsData.Open szSQL, rsCon, 0, 1, 1

I am calling the subroutine with the following data:

GetData "export.csv", "export", "A:AH", "BirdFeet", "B1", "sku", True, True

Here is the complete subroutine.

I was not using the path to the directory that holds the csv file in the szConnect string. I was using the file name not the path.

I added a string "strWorkingDir" and set it equal to the directory of the files and now It works fine.

SQL does not support the <> operation on Null. Replace

"SELECT * FROM [export$] WHERE price <> NULL ORDER BY sku;"

with

"SELECT * FROM [export$] WHERE price IS NOT NULL ORDER BY sku;"

This similar question explains the rationale. link
