Determine the length of the longest string in a CSV file to figure out the optimal "x" for an NVARCHAR(x)
Posted on 2008-10-03
I want to know the best way to see, for each column in a CSV file, what the longest string is in the column. This way we can pick a number of characters that is 20% larger than this for a cushion. I know i could just use an nvarchar(max), but I think this is needlessly wasteful. I know I could do something like this in excel, but I think the best solution would be a little command/script I could run in Powershell or something.
