• Visual Basic Size in bytes of a boolean

  How do I get the size, in bytes, of a boolean variable It appears to be a single (1) byte by empirical testing, but the documentation seems to imply that it depends upon the 'implementing platform'.

The column definition will be [ref] [int] NOT ...Show All

I was very surprise and shocked when it took three days to process only 600,000 rows of a 3 million row result. Because of the time it took to only process 600,000 rows I canceled the batch job and did everything in SQL using Query Analyzer. I was able to process the same volume in only 45 minutes. I was greatly disappointed in the results. T ...Show All
