Insert boolean true / false to Postgres and MySQL

Question

i fight with DB, trying to insert true and false values to my table with column boolean, but always getting just error:

Invalid parameter number

tested with:

$value = true
$value = "true"
$value = 1

Can somebody please advise me? Thanks

EDIT: full code would looks like:

// adding value to variabile
                    if (empty($row['vin']))
                        $vin = 0;                   
                    else
                        $vin = 1;
//calling insert method
$this->insertToTable($model_code, $typ, $kind, $ts, $vin,  $smr, $ire, $manufacturer_code);

//full insert method:
    public function insertToTable($code, $name, $kind, $ts, $vin, $smr, $ire, $manufacturer_code)
    {                   
        try {                                       
            $con = new PDO( DB_HOST, DB_USER, DB_PASS );            
            $con->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );            
            $sql = "INSERT INTO r_vehicle_model(code, name, kind, ts, vin, smr, ire, manufacturer_code) VALUES(:code, :name, :kind, :ts, :smr, :ire, :manufacturer_code)";
            $stmt = $con->prepare( $sql );
            $stmt->bindValue( 'code', $code, PDO::PARAM_STR );                
            $stmt->bindValue( 'name', $name, PDO::PARAM_STR );                
            $stmt->bindValue( 'kind', $kind, PDO::PARAM_STR );                
            $stmt->bindValue( 'ts', $ts, PDO::PARAM_STR );                
            $stmt->bindValue( 'vin', $vin, PDO::PARAM_STR );                
            $stmt->bindValue( 'smr', $smr, PDO::PARAM_STR );                
            $stmt->bindValue( 'ire', $ire, PDO::PARAM_STR );                
            $stmt->bindValue( 'manufacturer_code', $manufacturer_code, PDO::PARAM_STR );                
            $stmt->execute();                
            }
        catch( PDOException $e ) {
                echo $e->getMessage();
            }           
    }   

full error:

SQLSTATE[HY093]: Invalid parameter number: :vin

Answer 1

Forget :vin in insert query. Number of parameter in values is not equal to bindValue

 $sql = "INSERT INTO r_vehicle_model(code, name, kind, ts, vin, smr, ire, manufacturer_code) VALUES(:code, :name, :kind, :ts, ,:vin ,:smr, :ire, :manufacturer_code)";

Answer 2

You're currently using PDO::PARAM_STR to specify that all the parameters you're passing are strings.

You should make choose the appropriate type for the field, so for a boolean consider using PDO::PARAM_BOOL
