** This file is automatically generated by the script in the canonical
|

** SQLite source tree at tool/mkshellc.tcl. That script combines source
|
|
** code from various constituent source files of SQLite into this single
|
|
** "shell.c" file used to implement the SQLite command-line shell.
|
|
**
|
|
** Most of the code found below comes from the "src/shell.c.in" file in
|
|
** the canonical SQLite source tree. That main file contains "INCLUDE"
|
|
** lines that specify other files in the canonical source tree that are
|
|
** inserted to getnerate this complete program source file.
|
|
**
|
|
** The code from multiple files is combined into this single "shell.c"
|
|
** source file to help make the command-line program easier to compile.
|
|
**
|
|
** To modify this program, get a copy of the canonical SQLite source tree,
|
|
** edit the src/shell.c.in" and/or some of the other files that are included
|
|
** by "src/shell.c.in", then rerun the tool/mkshellc.tcl script.

** The sha3(X) function computes the SHA3 hash of the input X, or NULL if

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

** ORDER BY 1;
