It would be convenient if it was possible to assign a context pointer to a sqlite3_stmt.
Example usage (pseudo C code):
```
sqlite3_stmt *new_stmt(struct meta_data *ctx) {
sqlite3_stmt stmt;
int rc = sqlite3_prepare_v2(...);
if (rc != SQLITE_OK) { /* error handling */ }
rc = sqlite3_stmt_set_context(stmt, ctx);
if (rc != SQLITE_OK) { /* error handling */ }
return stmt;
}
/* later, iterate over all statements: */
void iterate() {
sqlite3_stmt *stmt = NULL;
while ((stmt = sqlite3_stmt_next(stmt))) {
struct meta_data *ctx = sqlite3_stmt_get_context(stmt);
/* do stuff with meta data */
}
}
```
