Inserting into and retrieving from binary string column

Hello,

I have a table MyKeys with a column that is a binary string of length 16 bytes: CREATE TABLE MyKeys (id INT AUTO_INCREMENT PRIMARY KEY, myKey BINARY(16)) Now I create an ArrayBuffer of size 16 bytes: var myBuffer = new ArrayBuffer(16); Now I want to insert it into the table: con.query('INSERT INTO MyKeys (myKey) VALUES (?)', [myBuffer],function (err, data) {}); However that is causing an error: ER_WRONG_VALUE_COUNT_ON_ROW: Column count doesn’t match value count at row 1 sql: “INSERT INTO MyKeys (myKey) VALUES ()” So it looks like myBuffer is not being sent to MySQL at all.

Any suggestions would be much appreciated. Thanks!

Seems to be working now. Thanks a million, @sidorares & @dougwilson

An ArrayBuffer cannot be read directly, as you need to overlay some kind of view over it to read. The Node.js Buffer is a view into an ArrayBuffer. You can create a Buffer view of an ArrayBuffer using Buffer.from(myArrayBuffer)
