I am trying to figure out how to check a column in my database to see if a bit is on or off. I have a bigint column that actually right now only represents 8 values or bits. What I need to do is check to see if the 5th value or 5th bit in this column is on or off. I have written one select statement that will give me everything up to the 5th bit but if the 6,7,and 8th bits are on with the 5th it ignores the count on those values. Here is my query:
select * from sometable where bigintcolumn >> 5=1;
Like I stated above this works fine until I have the 5th bit on with a bit from position 6 or greater on also. It will ignore these values. I guess I may be truncating everything past the 5th bit position in my query above.
