Dear list,
I hope this to be a simple question. I have need to simply read the first
row in a given table. Right now, I have some legacy code that selects all
rows in a table just to see if the first row has a certain value.
The code is seeking to see if an update has been run or not. A hypothetical
scenario would be: has an update been run to populate data into a new
column in a table. Neither the data nor any of the rows are consistently
known. So the test selects all rows, tests the first row and then ends if
the column has a value.
Does anyone have a better way to do this?
Regards
