Title
Body
I tried to write t=t|128 but got an out of range error. I suspect tinyint is signed. However http://dev.mysql.com/doc/refman/5.5/en/numeric-types.html says it may be unsigned (below). But it doesn't say how to make it unsigned. How do I? Type Storage Minimum Value Maximum Value (Bytes) (Signed/Unsigned) (Signed/Unsigned) TINYINT 1 -128 127 0 255 SMALLINT 2 -32768 32767 0 65535 MEDIUMINT 3 -8388608 8388607 0 16777215 INT 4 -2147483648 2147483647 0 4294967295 BIGINT 8 -9223372036854775808 9223372036854775807 0 18446744073709551615
