Here's one that I wrote a while back:
void sqlite3_instr(sqlite3_context* pContext, int argc, sqlite3_value** argv)
{
const char *str1 = (const char *) sqlite3_value_text(argv[0]);
const char *str2 = (const char *) sqlite3_value_text(argv[1]);
char *p = strstr(str1, str2);
int nResult = 0;
if(p != NULL)
{
nResult = p - str1 + 1;
}
sqlite3_result_int(pContext, nResult);
}
You'll need to register it as an extension function on the database connection,
but it should do the job.
