Empty result after INSERT query about node-ibm_db

[wilk]

Well, it's my fault.
Query is just a method to execute a pure SQL statement and follows the solution

SELECT * FROM NEW TABLE (INSERT INTO Users (name, age) VALUES ("Wilk", 26))

By the way, it could be an interesting feature returning the last inserted record after an INSERT sql query ;)

Are you using a prepare statement? I can't seem to get anything back from an INSERT.

I can't figure out how to INSERT an escaped string, which leaves me vulnerable to errors and SQL injection. Of course, the prepare doesn't seem to return the new inserted row.

What a conundrum.

You can use a prepare statement here, to insert an escaped string. You can use the following code snippet as a reference to use prepare statement.

var value = 'AB$C\'DI';
var queryString = "INSERT INTO ***** VALUES(?)";
conn.prepare(queryString, function(err, stmt) {

        stmt.bindSync([value]);
        stmt.executeSync(stmt);
        console.log('Statement executed');

        queryString = "SELECT * FROM *******";
        conn.query(queryString, function (err, data) {
            if (err) {
                console.log('Error recieved: \n'+err);
            }
            console.log(JSON.stringify(data));
        });

        conn.close(function(){
            console.log("Connection Closed");
        });
    });

The insert statement will not return the last row. If you need to fetch the key of the last inserted row, in case of auto generated keys, you can use the following query

SELECT IDENTITY_VAL_LOCAL() FROM SYSIBM.SYSDUMMY1'

This query will fetch the latest key generated within a transaction scope and return it back to the user.

If this does not resolve your issue, please share more details, so that we can take a look.

this works, but if another solution exists ... i buy it

SELECT IDENTITY_VAL_LOCAL() FROM SYSIBM.SYSDUMMY1
