Okay. I worked out a solution, but I am still unsure of why it fixes the
problem. Or rather, I know why it works, but it still doesn't explain why the
basic_string::c_str() call did not work. My only guess is that
basic_string::c_str() doesn't really provide a pointer to a null-terminated
c-style string, but a facsimile of one that SQLite doesn't like.
Here's that statement from my code again with the mods included that make the
code work:
char *surbuf[100];
memset(surbuf, 0, 100);
strcpy(surbuf, CurrentName -> second.GetSurName().c_str());
idx = -1;
idx = sqlite3_bind_parameter_index(ResultStmt, ":sur");
sqlite3_bind_text(ResultStmt, idx, surbuf, strlen(surbuf),
SQLITE_STATIC);
BTW, I was using the .output command in the SQLITE3 shell to attempt piping my
output to a file. The command looked like this:
.output c:\sqlite.txt
Select * from Names;
When I went to the root of C: I did not find the file. So I removed the path
from the filename and later found it in the SQLLite directory from which I was
running the shell.
