Hey Guy's,
I have ported SQLITE over VRTX based embedded platform, now after using for a 1
year suddenly started getting SQLITE_CORRUPT ERORR, used queue and mutex at
application level to make sqilte DB access thread safe as sqlite library itself
is compiled without thread safe options, Strange
Hi Everyone,
I have patched my SQLite3.exe source (shell.c) to have an ".import"
function witch can read ".mod csv" exports :
- can read QUOTE + TEXT + CRLF + TEXT + QUOTE
- can read QUOTE + SEPARATOR + QUOTE
- can read QUOTE + TEXT + SEPARATOR + TEXT + QUOTE
- can read QUOTE + TEXT + 2QUOTES
Hello,
I'll try to explain my problem:
I have a Symbol MC3090 Data Collector with VB.Net 2005. I have a database
with 80,000 records on the computer.
For example: I search all words that begin with "shirt" and show in the Grid
Collector.
Sometimes search found 200 records. When I do a query via

Just that. You have a programming language with variables, so use it. That's

Simon, can you expand your syntax, or are you just saying, "get x,y,z store
them in a set of variables, then run update with appropriate bindings"?
Hopefully this related question isn't called hijacking a thread. I feel this
belongs together under set multiple values using the update query.

Reading your response, thinks.
I did however find that the incoming data did not conform to what I
expects (contiguous series_id),
so the code worked, my thinking did not.

Thanks Simon. I believe you're correct in that I can recreate all
dependant tables. I had attempted this trick earlier, but was doing
so in the context of immediate mode constraints, and that made the
re-insertion of data and dropping of tables exceptionally complicated
in some cases (such as cir

Yes. You can make one process, which handles all your SQLite transactions, and
receives its orders from other processes via inter-process calls or TCP/IP.

TCP-socket listening daemon + SQLite in-memory database may be helpful.

It's impossible with current SQLite code base. Even if you try to
implement your own database cache and will allocate it in some shared
memory it won't work because along with cache pages SQLite also stores
some internal information which s

Hahaha. Wrong way up. That should be
The select/group by part of your statement will group table SERIESDATA by
text-column series_id (aliased to id) and return the min and max data_index
for each grouping, assuming those columns are populated with data for each
row. The set will have three columns and some number of rows, one per id.

Hi,
I am trying to implement a shared queue (to asynchronously exchange messages
between processes) using SQLite.
Since I do not need my queues to be persistent (at least for now), I do not
want to use disk based SQLite database (for better performance).
I see there is an option to create purely
select top 10 * from dailyRankingTable
union all
SELECT a.* FROM dailyRankingTable a, friendTable b WHERE upper(b.player)
= upper('?') AND upper(b.friend) = upper(a.name)
Top 10 does not work for SQlite I believe. But you might can find something
like it.

Hey guys.
I have the following query:
SELECT a.* FROM dailyRankingTable a, friendTable b WHERE upper(b.player)
= upper('?') AND upper(b.friend) = upper(a.name)
(ignore the uppers for now - I'm going to refactor soon)
I would like this query to also select the first 10 elements of
dailyRanking
20 matches
