How do I deal with MEMO, TEXT, HYPERLINK, and CURRENCY columns?
MEMO / TEXT / VARCHAR(>255)
Depending on the version of your MDAC driver, and the database you are connecting to, these columns can either (a) not show up at all, (b) only show up the first time they're called, or (c) cause 'Unspecified Error', 'Exception Occured' or 'Errors Occurred' runtime errors, if the following recommendations are not observed:
Here is some example syntax:
Hyperlink, Currency, MONEY
Many people assume that, because Access can understand that a hyperlink column should be underlined and clickable and that a currency column starts with a dollar sign and is followed by two decimal places, the browser should be able to as well. So they write syntax like this:
And expect the browser to automatically wrap the hyperlink in an anchor tag, and format the currency column appropriately. Unfortunately, this isn't how it works. HTML doesn't know what a hyperlink is, unless you tell it to use an <A> tag. Similarly, HTML doesn't automatically format your numbers and assume you want thousands separators and dollar signs.
DO NOT use the hyperlink datatype in Access. This is designed to allow users to click on links in the GUI. It is NOT meant for presentation-layer formatting (e.g. HTML). Use a VARCHAR column for hyperlinks. I would also recommend using a numeric data type with two decimal places for currency; in SQL Server, use the MONEY datatype. storing dollar signs and #link# values in the table aren't going to help you in HTML, and only add unnecessary storage size to your tables.
Based on that, to format these values in your HTML, you need to do something like this (from Access)):
To get a hyperlink formatted properly right out of SQL Server, you can use:
To get a money value formatted properly right out of SQL Server, you can use:
Some people have reported that this doesn't properly insert commas (I assume it has to do with collation or regional settings on the server). So, to force it using a bunch of wacky string manipulation, you can try something like this:
Please let us know if this still doesn't work in your environment.
