Hi .,
When I try to solve a sudoku of 9X9 ., I get a error with this
message.

Error Code : 1116
Too many tables; MySQL can only use 61 tables in a join

I need to join more tables [self-join]. The version used is 5.x .
Is there any remedy to by-pass, or trick?

Help me to find the solution.

Thanks.

I'm so sorry Kesavan, but my crystal ball has broken down. It is not
showing me any of your code or why your design requires so many joins.

Maybe one of the others who hang around this forum has a working
crystal ball.

Hi Captain.,

Hi Wasmus.,
This query is generated from that The_Lost_Art_of_the_Self_Join. I
test it for 6x6 .Good.,
But I need to test the same for 9*9.

Help me.,
