c++ - SQLITE_MISUSE in prepared statement -

i'm getting sqlite_misuse error on following code, , wondering if might caused having table name bound parameter? different causes of sqlite_misue?

const char sqlneuralstateinsert[] =     "insert ?1(layer_id, neuron_id, input_id, value)"     "values(?2, ?3, ?4, ?5);"; sqlite3_stmt* stmt1; rc = sqlite3_prepare_v2(db, sqlneuralstateinsert, -1, &stmt1, null); if(rc){     //!< failed prepare insert statement } sqlite3_bind_text(stmt1, 1, this->getnname().c_str(), -1, sqlite_static);  for(uint32_t = 0; < m_nlayers; i++){     sqlite3_bind_int(stmt1, 2, i); // layer id     for(uint32_t j = 0; j < m_layers[i]->getneuroncount(); j++){         std::vector<double> weights = m_layers[i]->getweights(j);         sqlite3_bind_int(stmt1, 3, j); // neuron id         for(uint32_t k = 0; k < weights.size(); k++){             sqlite3_bind_int(stmt1, 4, k);             sqlite3_bind_double(stmt1, 5, weights[k]);             rc = sqlite3_step(stmt1);             printf("%d\n", rc);         }     } } sqlite3_finalize(stmt1); 

you're right; you cannot bind table name:

generally 1 cannot use sql parameters/placeholders database identifiers (tables, columns, views, schemas, etc.) or database functions (e.g., current_date), instead binding literal values.

you have trivially tested hypothesis hard-coding table name.
