    I can’t imagine any possible reason why I would do such a thing. Dividing up into 3 tables will make the data much harder to query later. But if you’re stuck with it then I would do something along the lines of this:

    BUild a mapping table with three columns A, B, C. Populate the table withthe values you want to go in each table. Shoulf look simliar to this, but woudl go out the the max value you will need. 

    A   B   C
1   2   3
4   5   6
7   8   9
10  11  12

    Create a temp table using row_number over (don’t forget to order by) to so that you can now tell which record is the first HA and which is the second etc. Now do 3 inserts joining on the number you generated to each column inteh mapping table. If they join to column A insert to tableA, Column B, insert totable B, colmn c insert to table c.
