chng {2002 Apr 06 (2.4.7)} {
|

<li>Add the ability to put TABLE.* in the column list of a
|
|
SELECT statement.</li>
|
|
<li>Permit SELECT statements without a FROM clause.</li>
|
|
<li>Added the <b>last_insert_rowid()</b> SQL function.</li>

|
|
do not contain a comparison operator.</li>

chng {2002 Apr 01 (2.4.5)} {
|
|
<li>Bug fix: Correctly handle functions that appear in the WHERE clause
|
|
of a join.</li>
|
|
<li>When the PRAGMA vdbe_trace=ON is set, correctly print the P3 operand
|
|
value when it is a pointer to a structure rather than a pointer to
|
|
a string.</li>
|
|
<li>When inserting an explicit NULL into an INTEGER PRIMARY KEY, convert
|
|
the NULL value into a unique key automatically.</li>

|
|
|
chng {2002 Mar 24 (2.4.4)} {
|
|
<li>Allow "VIEW" to be a column name</li>
|
|
<li>Added support for CASE expressions (patch from Dan Kennedy)</li>
|
|
<li>Added RPMS to the delivery (patches from Doug Henry)</li>
|
|
<li>Fix typos in the documentation</li>
|
|
<li>Cut over configuration management to a new CVS repository with
|
|
its own CVSTrac bug tracking system.</li>
|
|
}

|
chng {2002 Mar 22 (2.4.3)} {
|
|
<li>Fix a bug in SELECT that occurs when a compound SELECT is used as a
|
|
subquery in the FROM of a SELECT.</li>
|
|
<li>The <b>sqlite_get_table()</b> function now returns an error if you
|
|
give it two or more SELECTs that return different numbers of columns.</li>
|
|
}
|
|
|
|
chng {2002 Mar 14 (2.4.2)} {
|
|
<li>Bug fix: Fix an assertion failure that occurred when ROWID was a column
|
|
in a SELECT statement on a view.</li>
|
|
<li>Bug fix: Fix an uninitialized variable in the VDBE that would could an
|
|
assert failure.</li>
|
|
<li>Make the os.h header file more robust in detecting when the compile is
|
|
for windows and when it is for unix.</li>
|
|
}
|
|
|
|
chng {2002 Mar 13 (2.4.1)} {
|
|
<li>Using an unnamed subquery in a FROM clause would cause a segfault.</li>
|
|
<li>The parser now insists on seeing a semicolon or the end of input before
|
|
executing a statement. This avoids an accidental disaster if the
|
|
WHERE keyword is misspelled in an UPDATE or DELETE statement.</li>
|
|
}
|
|
|
|
|
|
chng {2002 Mar 10 (2.4.0)} {
|
|
<li>Change the name of the sanity_check PRAGMA to <b>integrity_check</b>
|
|
and make it available in all compiles.</li>
|
|
<li>SELECT min() or max() of an indexed column with no WHERE or GROUP BY
|
|
clause is handled as a special case which avoids a complete table scan.</li>
|
|
<li>Automatically generated ROWIDs are now sequential.</li>
|
|
<li>Do not allow dot-commands of the command-line shell to occur in the
|
|
middle of a real SQL command.</li>
|
|
<li>Modifications to the "lemon" parser generator so that the parser tables
|
|
are 4 times smaller.</li>
|
|
<li>Added support for user-defined functions implemented in C.</li>
|
|
<li>Added support for new functions: <b>coalesce()</b>, <b>lower()</b>,
|
|
<b>upper()</b>, and <b>random()</b>
|
|
<li>Added support for VIEWs.</li>
|
|
<li>Added the subquery flattening optimizer.</li>
|
|
<li>Modified the B-Tree and Pager modules so that disk pages that do not
|
|
contain real data (free pages) are not journalled and are not
|
|
written from memory back to the disk when they change. This does not
|
|
impact database integrity, since the
|
|
pages contain no real data, but it does make large INSERT operations
|
|
about 2.5 times faster and large DELETEs about 5 times faster.</li>
|
|
<li>Made the CACHE_SIZE pragma persistent</li>
|
|
<li>Added the SYNCHRONOUS pragma</li>
|
|
<li>Fixed a bug that was causing updates to fail inside of transactions when
|
|
the database contained a temporary table.</li>
|
|
}
|
|
|
|
chng {2002 Feb 18 (2.3.3)} {
|
|
<li>Allow identifiers to be quoted in square brackets, for compatibility
|
|
with MS-Access.</li>
|
|
<li>Added support for sub-queries in the FROM clause of a SELECT.</li>
|
|
<li>More efficient implementation of sqliteFileExists() under Windows.
|
|
(by Joel Luscy)</li>
|
|
<li>The VALUES clause of an INSERT can now contain expressions, including
|
|
scalar SELECT clauses.</li>
|
|
<li>Added support for CREATE TABLE AS SELECT</li>
|
|
<li>Bug fix: Creating and dropping a table all within a single
|
|
transaction was not working.</li>
|
|
}
|
|
|
|
chng {2002 Feb 14 (2.3.2)} {
|
|
<li>Bug fix: There was an incorrect assert() in pager.c. The real code was
|
|
all correct (as far as is known) so everything should work OK if you
|
|
compile with -DNDEBUG=1. When asserts are not disabled, there
|
|
could be a fault.</li>
|
|
}
|
|
|
|
chng {2002 Feb 13 (2.3.1)} {
|
|
<li>Bug fix: An assertion was failing if "PRAGMA full_column_names=ON;" was
|
|
set and you did a query that used a rowid, like this:
|
|
"SELECT rowid, * FROM ...".</li>
|
|
}
|
|
|
|
chng {2002 Jan 30 (2.3.0)} {
|
|
<li>Fix a serious bug in the INSERT command which was causing data to go
|
|
into the wrong columns if the data source was a SELECT and the INSERT
|
|
clauses specified its columns in some order other than the default.</li>
|
|
<li>Added the ability to resolve constraint conflicts is ways other than
|
|
an abort and rollback. See the documentation on the "ON CONFLICT"
|
|
clause for details.</li>
|
|
<li>Temporary files are now automatically deleted by the operating system
|
|
when closed. There are no more dangling temporary files on a program
|
|
crash. (If the OS crashes, fsck will delete the file after reboot
|
|
under Unix. I do not know what happens under Windows.)</li>
|
|
<li>NOT NULL constraints are honored.</li>
|
|
<li>The COPY command puts NULLs in columns whose data is '\N'.</li>
|
|
<li>In the COPY command, backslash can now be used to escape a newline.</li>
|
|
<li>Added the SANITY_CHECK pragma.</li>
|
|
}
|
|
|
|
chng {2002 Jan 28 (2.2.5)} {
|
|
<li>Important bug fix: the IN operator was not working if either the
|
|
left-hand or right-hand side was derived from an INTEGER PRIMARY KEY.</li>
|
|
<li>Do not escape the backslash '\' character in the output of the
|
|
<b>sqlite</b> command-line access program.</li>
|
|
}
|
|
|
|
chng {2002 Jan 22 (2.2.4)} {
|
|
<li>The label to the right of an AS in the column list of a SELECT can now
|
|
be used as part of an expression in the WHERE, ORDER BY, GROUP BY, and/or
|
|
HAVING clauses.</li>
|
|
<li>Fix a bug in the <b>-separator</b> command-line option to the <b>sqlite</b>
|
|
command.</li>
|
|
<li>Fix a problem with the sort order when comparing upper-case strings against
|
|
characters greater than 'Z' but less than 'a'.</li>
|
|
<li>Report an error if an ORDER BY or GROUP BY expression is constant.</li>
|
|
}
|
|
|
|
chng {2002 Jan 16 (2.2.3)} {
|
|
<li>Fix warning messages in VC++ 7.0. (Patches from nicolas352001)</li>
|
|
<li>Make the library thread-safe. (The code is there and appears to work
|
|
but has not been stressed.)</li>
|
|
<li>Added the new <b>sqlite_last_insert_rowid()</b> API function.</li>
|
|
}
|
|
|
|
chng {2002 Jan 13 (2.2.2)} {
|
|
<li>Bug fix: An assertion was failing when a temporary table with an index
|
|
had the same name as a permanent table created by a separate process.</li>
|
|
<li>Bug fix: Updates to tables containing an INTEGER PRIMARY KEY and an
|
|
index could fail.</li>
|
|
}
|
|
|
|
chng {2002 Jan 9 (2.2.1)} {
|
|
<li>Bug fix: An attempt to delete a single row of a table with a WHERE
|
|
clause of "ROWID=x" when no such rowid exists was causing an error.</li>
|
|
<li>Bug fix: Passing in a NULL as the 3rd parameter to <b>sqlite_open()</b>
|
|
would sometimes cause a coredump.</li>
|
|
<li>Bug fix: DROP TABLE followed by a CREATE TABLE with the same name all
|
|
within a single transaction was causing a coredump.</li>
|
|
<li>Makefile updates from A. Rottmann</li>
|
|
}
|
|
|
|
chng {2001 Dec 22 (2.2.0)} {
|
|
<li>Columns of type INTEGER PRIMARY KEY are actually used as the primary
|
|
key in underlying B-Tree representation of the table.</li>
|
|
<li>Several obscure, unrelated bugs were found and fixed while
|
|
implemented the integer primary key change of the previous bullet.</li>
|
|
<li>Added the ability to specify "*" as part of a larger column list in
|
|
the result section of a SELECT statement. For example:
|
|
<nobr>"<b>SELECT rowid, * FROM table1;</b>"</nobr>.</li>
|
|
<li>Updates to comments and documentation.</li>
|
|
}
|
|
|
|
chng {2001 Dec 14 (2.1.7)} {
|
|
<li>Fix a bug in <b>CREATE TEMPORARY TABLE</b> which was causing the
|
|
table to be initially allocated in the main database file instead
|
|
of in the separate temporary file. This bug could cause the library
|
|
to suffer an assertion failure and it could cause "page leaks" in the
|
|
main database file.
|
|
<li>Fix a bug in the b-tree subsystem that could sometimes cause the first
|
|
row of a table to be repeated during a database scan.</li>
|
|
}
|
|
|
|
chng {2001 Dec 14 (2.1.6)} {
|
|
<li>Fix the locking mechanism yet again to prevent
|
|
<b>sqlite_exec()</b> from returning SQLITE_PROTOCOL
|
|
unnecessarily. This time the bug was a race condition in
|
|
the locking code. This change effects both POSIX and Windows users.</li>
|
|
}
|
|
|
|
chng {2001 Dec 6 (2.1.5)} {
|
|
<li>Fix for another problem (unrelated to the one fixed in 2.1.4)
|
|
that sometimes causes <b>sqlite_exec()</b> to return SQLITE_PROTOCOL
|
|
unnecessarily. This time the bug was
|
|
in the POSIX locking code and should not effect windows users.</li>
|
|
}
|
|
|
|
chng {2001 Dec 4 (2.1.4)} {
|
|
<li>Sometimes <b>sqlite_exec()</b> would return SQLITE_PROTOCOL when it
|
|
should have returned SQLITE_BUSY.</li>
|
|
<li>The fix to the previous bug uncovered a deadlock which was also
|
|
fixed.</li>
|
|
<li>Add the ability to put a single .command in the second argument
|
|
of the sqlite shell</li>
|
|
<li>Updates to the FAQ</li>
|
|
}
|
|
|

chng {2001 Nov 23 (2.1.3)} {
|
|
<li>Fix the behavior of comparison operators
|
|
(ex: "<b><</b>", "<b>==</b>", etc.)
|
|
so that they are consistent with the order of entries in an index.</li>
|
|
<li>Correct handling of integers in SQL expressions that are larger than
|
|
what can be represented by the machine integer.</li>
|
|
}

|
chng {2001 Nov 22 (2.1.2)} {
|
|
<li>Changes to support 64-bit architectures.</li>
|
|
<li>Fix a bug in the locking protocol.</li>
|
|
<li>Fix a bug that could (rarely) cause the database to become
|
|
unreadable after a DROP TABLE due to corruption to the SQLITE_MASTER
|
|
table.</li>
|
|
<li>Change the code so that version 2.1.1 databases that were rendered
|
|
unreadable by the above bug can be read by this version of
|
|
the library even though the SQLITE_MASTER table is (slightly)
|
|
corrupted.</li>
|
|
}
|
|
|
|
chng {2001 Nov 13 (2.1.1)} {
|

<li>Bug fix: Sometimes arbirary strings were passed to the callback
|
|
function when the actual value of a column was NULL.</li>
|
|
}
|
|
|
|
chng {2001 Nov 12 (2.1.0)} {
|
|
<li>Change the format of data records so that records up to 16MB in size
|
|
can be stored.</li>
|
|
<li>Change the format of indices to allow for better query optimization.</li>
|
|
<li>Implement the "LIMIT ... OFFSET ..." clause on SELECT statements.</li>
|
|
}
|
|
|
|
chng {2001 Nov 3 (2.0.8)} {
|
|
<li>Made selected parameters in API functions <b>const</b>. This should
|
|
be fully backwards compatible.</li>
|
|
<li>Documentation updates</li>
|
|
<li>Simplify the design of the VDBE by restricting the number of sorters
|
|
and lists to 1.
|
|
In practice, no more than one sorter and one list was ever used anyhow.

|
|
an identifier.</li>
|
|
<li>Patches from Christian Werner to improve ODBC compatibility and to
|
|
fix a bug in the round() function.</li>
|
|
<li>Plug some memory leaks that use to occur if malloc() failed.
|
|
We have been and continue to be memory leak free as long as
|
|
malloc() works.</li>
|

<li>Changes to some test scripts so that they work on Windows in
|
|
addition to Unix.</li>
|

chng {2001 Oct 19 (2.0.6)} {

is turned on.</li>

<li>Added the COUNT_CHANGES pragma.</li>

Now it returns 0.</li>

chng {2001 Oct 13 (2.0.4)} {

<li>Bug fix: an abscure and relatively harmless bug was causing one of

|
the tests to fail when gcc optimizations are turned on. This release
|
|
fixes the problem.</li>

|
}
|
|
|

chng {2001 Oct 13 (2.0.3)} {
|
|
<li>Bug fix: the <b>sqlite_busy_timeout()</b> function was delaying 1000
|
|
times too long before failing.</li>
|
|
<li>Bug fix: an assertion was failing if the disk holding the database
|
|
file became full or stopped accepting writes for some other reason.
|
|
New tests were added to detect similar problems in the future.</li>
|
|
<li>Added new operators: <b>&</b> (bitwise-and)
|
|
<b>|</b> (bitwise-or), <b>~</b> (ones-complement),
|
|
<b><<</b> (shift left), <b>>></b> (shift right).</li>
|

<li>Removed some unused "#include <unistd.h>" that were causing problems
|
|
for VC++.</li>
|
|
<li>Fixed <b>sqlite.h</b> so that it is usable from C++</li>
|
|
<li>Added the FULL_COLUMN_NAMES pragma. When set to "ON", the names of
|
|
columns are reported back as TABLE.COLUMN instead of just COLUMN.</li>
|
|
<li>Added the TABLE_INFO() and INDEX_INFO() pragmas to help support the
|
|
ODBC interface.</li>

using compilers other than gcc.</li>

<li>The ".dump" output from the shell does not work if there are embedded
|
|
newlines anywhere in the data. This is an old bug that was carried
|
|
forward from version 1.0. To fix it, the ".dump" output no longer
|
|
uses the COPY command. It instead generates INSERT statements.</li>
|
|
<li>Extend the expression syntax to support "expr NOT NULL" (with a
|
|
space between the "NOT" and the "NULL") in addition to "expr NOTNULL"
|

(with no space).</li>

to "SQLus" was abandoned in favor of keeping the "SQLite" name and

bumping the major version number.</li>

available backend.</li>

option is given to configure. The default behavior is to assume

iso8859-x, as it has always done. This only makes a difference for
|
|
LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>

<li>If the library is not configured for UTF-8 and the Tcl library
|

is one of the newer ones that uses UTF-8 internally,

then a conversion from UTF-8 to iso8859 and

|
back again is done inside the TCL interface.</li>

for rollback or atomic commit.</li>

<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
|
|
unique random integer key associated with every row of every table.</li>

feature and the TCL interface bugs mentioned below.</li>

numbers of records to be deleted or updated into a temporary file.

This is changed so that the record numbers are held in memory.</li>
