Question #2356
Hi All, I am trying to update my SQL table with 0 and 1. I have design a code that enables me to read sql table and write the result to text file. The problem is that i would like to convert 0 values to 1 randomly based on percent. For example, assume that table A is columns *4 rows with values 0 and 1. The current percentage of 1 is 6/16. which is %37.5 I would like to increase the current percentage to 50%. To do so i need to convert randomly additional two 0s to 1 to get the total 8 of values 1. I appreciate your assistant in advance. For example: Table A a1 a2 a3 ... am 1 0 0 1 ... 1 2 0 1 0 ... 0 3 0 0 1 ... 0 4 1 1 0 0 ... n
