Hello,
I am loading a large file to a SQLite database table.
The file has a proprietary format that does not lend
itself to the COPY command. So, I am parsing the file
and doing insert statements. While there are around 2
million records, I am doing them in blocks of a few
thousand at a time.

Prepared statements are implemented in SQLite 2.8.x. See sqlite.h for
exact API and how to use it.
Its very similar to SQLite3 API. Something along the lines of

This is wrong. Column c2 only exists in table b and so it can't be
ambiguous. I suspect you are using different

All it does is slurp input, concatenate it into one long string and then

It must be operator head space on my part...
Thanks for looking though

There is no way to know which table the c1 column value is associated with

Storing BLOBs in a database then acessing elements of them using other
tools does not look like good design. The purpose of a database and its
data manipulation language is to give access to all data elements. Are
you really using the DB in the best way? Would it be better to form

hi everyone,
recently I crosscompiled sqlite3.3.5 for my armlinux.
I have got some basic knowlage of using it now.
i wrote a c program which just open a database ,print table values and then
exit.
to write the Makefile, i use
$(EXE):$(OBJS)

Derrell,
I don't see a problem with either of your problem que
Large chunks of the array will be accessed. Very rarely (if ever)
will just one value of the array be needed. From what you guys are
saying, this makes it seem like a BLOB would be the way to go. Another
thing i forgot to mention, each name will most likely have not one, but
many arrays ass

Hello to all,
I would like to propose a new API function:
long long int sqlite3_column_rowid(sqlite3_stmt*, int iCol);
As the name implies, this function would return the RowID for a given column
after sqlite3_step has returned SQLITE_DATA. The RowID would be valid for the
database and table
Jay is correct here, only use a blob if you do not want to search on that
field. Your example may not be best suited to BLOB but that is for you to
decide.
We store medical test data as a blob. This is not much more complicated than an
array of C structs. However we have a primary key field, a

I understand Windows is poor, but I do not fully understand the
compilation process. The mkopc3.exe is actually created- so this itself
cannot be the problem. Not having awk doesn't seem to be an issue for
compiling the 3.2.1-based driver either (see 1).
Sorry, I'm confused :(
