VB.Net - Referencing Decimal Type in DataTable

Good Day Experts!

I am iterating through a DataTable referencing values in it for a select query.

Here is the portion of the select query where sqlRSGetLineItems is the DataRow in the below For Each loop:

[BATCH NUMBER]='" & sqlRSGetLineItems("BATCH NUMBER").Value & "''

For Each sqlRSGetLineItems In sqlRStbl.Rows

Next

Issue I have is that "BATCH NUMBER" is decimal.  So how do I reference it for use in the query? I am getting an error since I am using .Value.

Thanks,

Try CDec(sqlRSGetLineItems("BATCH NUMBER").Value.Tostring("f2"))

The f2 is just for 2 decimal Places...

I think the reason for error is that you are enclosing it in ' ' which is for varchar type

Change

[BATCH NUMBER]='" & sqlRSGetLineItems("BATCH NUMBER").Value & "''

to

[BATCH NUMBER]=" & sqlRSGetLineItems("BATCH NUMBER").Value

This may sound odd but...

I don't even have an understanding how/why I have to do the converting and .Value or .ToString.  

Are there rules anywhere that can guide me?

I spent hours and hours converting this code using .Value.  At the time I thought it was right since I didnt get any syntax errors.  But now everywhere I have it I get an error when I run it.

Thanks,

After reviewing your response and jtoutou's, I had to use the following combination to get the code to work:

[BATCH NUMBER]='" & CDec(sqlRSGetLineItems("BATCH NUMBER").ToString) & "'

It works.  Why do you ask? Am I missing something other than not understanding like in my post ID: 38835293?
