Trim all Database Fields Before Using Them in Forms

Depending on the data type used, many databases (for example, Microsoft SQL Server) pad returned data with spaces up to the length of the field. This is not a problem when fields are displayed (even if there is extra white space HTML will ignore it), but this can be quite annoying if the field is used to populate a FORM field (using the tags VALUE attribute). The solution? Any time you use a database field to populate a form field make sure to use the Trim() function (or the RTrim() function) to strip any trailing white space, so instead of VALUE=”#name#” use VALUE=”#Trim(name)#”.
