Is there any way to have an intsert into an FTS3 table ignore a row if the
ROWID being inserted already exists? This is turning out to be quite
troublesome because I'm inserting thousands of records where just a few like
3 or 4 will have the same rowid as existing records. However, to do the test
You could try to prepare a statement like "SELECT YourColumnName FROM
YourTable;" If prepare returns an error, then likely the error message will say
the column doesn't exist. If no error, it does exist. Such a simple query
shouldn't take long to prepare. Probably less time then to grab the resu

In your specific example you could simply define a custom "LIKE"
function, and LIKE could become Unicode aware without any goofy new
operators.

Hello all,
I just wanted to find out whether or not this is the

Hi,
many thanks for your answer,
I just think that it could be useful to know if an index is optimal or not,
kind of a tool that could give you the best index for speed up a query.
Many thanks,

Another way
SELECT name, sql FROM sqlite_master WHERE type='table' and name ='yourtable
name'
the field sql will give you the full table structure as a string. Parse for
your desired table name.
No statements fail.

Is it currently possible to specify that a user-defined function is of
type infix, using the extension framework?
It would be really easier to use, say a Unicode-aware LIKE named LIKEU
under the infix form:
... test LIKEU pattern ...
than
... LIKEU(pattern, test

Yes of course, but I'm doing so to keep the possibility to use the
native operator as well.

you need follows

Hello,
I have a question regarding a modification I've made to the ATTACH
DATABASE command in Sqlite. The attached diff file (set against version
3.6.17) shows the modifications I've made, which I hope can be read quite
simply.
The modification involves adding an optional "READONLY" keyword;
I have a SQLite database working quite nicely. The three main tables
have 4 million rows and 275,000 rows respectively, and query response
times are excellent: I have used several GUI front ends to query the
data, and they jibe with each other, both with regard to the (accurate)
results they re
