Right. So it's retreival that's the issue when this occurs, because I
do:
int col_type = sqlite3_column_type(stmt, i);
and it returns SQLITE_TEXT, so I then do:
val = (char*)sqlite3_column_text(stmt, i);
which doesn't return a length for me.
Would sqlite3_column_bytes() return the right length there rather than
me doing strlen() on the resulting data?
yes it will.
OK, so 1.11 is on CPAN which fixes this. However I have another bug
report about this not working for user defined functions, where I do
this:
s = SvPV(result, len);
sqlite3_result_text( context, s, len, SQLITE_TRANSIENT );
(SvPV is a macro that retrieves a char* from result, and as a side
effect sets len to the length of the string in bytes, even if it
contains nuls).
Is this maybe a bug in sqlite3_result_text()? I could patch it to do:
if (memchr(s, 0, len)) {
/* if the result contains NUL(s) treat it as a blob */
sqlite3_result_blob(context, s, len, SQLITE_TRANSIENT );
}
else {
sqlite3_result_text( context, s, len, SQLITE_TRANSIENT );
}
But that seems a waste of resources if it's a bug in
sqlite3_result_text().
Matt.
