removing-whitespace

I have a table with two fields (countries and ISO codes): Table1 field1 - e.g. 'Afghanistan' (without quotes) field2 - e.g. 'AF'(without quotes) In some rows the second field has whitespace at the start and/or end, which is affecting queries. Table1 field1 - e.g. 'Afghanistan' (without quotes) field2 - e.g. ' AF' (without quotes but with that space in front) Is there a way (in SQL) to go through the table and find/replace the whitespace in field2? You're looking for TRIM . UPDATE FOO set FIELD2 = TRIM(FIELD2); A general answer that I composed from your answers and from other links and it

How can I remove all white space from the beginning and end of a string? Like so: "hello" returns "hello" "hello " returns "hello" " hello " returns "hello" " hello world " returns "hello world" Mau String.Trim() returns a string which equals the input string with all white-spaces trimmed from start and end: " A String ".Trim() -> "A String" String.TrimStart() returns a string with white-spaces trimmed from the start: " A String ".TrimStart() -> "A String " String.TrimEnd() returns a string with white-spaces trimmed from the end: " A String ".TrimEnd() -> " A String" None of the methods modify

I'm calling a REST API and am receiving an XML response back. It returns a list of a workspace names, and I'm writing a quick IsExistingWorkspace() method. Since all workspaces consist of contiguous characters with no whitespace, I'm assuming the easiest way to find out if a particular workspace is in the list is to remove all whitespace (including newlines) and doing this (XML is the string received from the web request): XML.Contains("<name>" + workspaceName + "</name>"); I know it's case-sensitive, and I'm relying on that. I just need a way to remove all whitespace in a string efficiently.
