30 * Implementation of the sha3_query(SQL,SIZE) function.
32 * This function compiles and runs the SQL statement(s) given in the argument.
33 * The results are hashed using a SIZE-bit SHA3. The default size is 256.
35 * The format of the byte stream that is hashed is summarized as follows:
44 * <sql> is the original SQL text for each statement run and <n> is the size of
45 * that text. The SQL text is UTF-8. A single R character occurs before the
46 * start of each row. N means a NULL value. I mean an 8-byte little-endian
47 * integer <int>. F is a floating point number with an 8-byte little-endian
48 * IEEE floating point value <ieee-float>. B means blobs of <size> bytes. T
49 * means text rendered as <size> bytes of UTF-8. The <size> values are
50 * expressed as little endian 8 byte integers.
53 * There are zero or more R segments, one for each row in the
54 * result set. After each R, there are one or more N, I, F, B, or T segments,
55 * one for each column in the result set. Segments are concatentated directly
56 * with no delimiters of any kind.
