node-odbc

A simple odbc interface for nodejs

Note: node-odbc is in early development. There might be some bugs left!

Supported types

node-odbc auto maps your types to the specific odbc types.

• number -> int32, int64, double
• string -> char, nchar, varchar, nvarchar
• date -> datetime

Examples

Callback:

let con = new odbc.Connection()
    .connect(connectionString);
 
// run query
con.executeQuery((res, err) => 
    {  
        if( err != null )
        {
            console.log( err );
        }
    },
    "CREATE TABLE tblTest( myColumn int )"
);
 
//insert data
con.executeQuery((res, err) => 
    { 
        if( err != null )
        {
            console.log( err );
        }
    },
    "INSERT INTO tblTest(myColumn)VALUES(?)", 250
);
 
 
//fetch data
con.executeQuery((res, err) => 
    {
        if( err != null )
        {
            console.log( err );
        }
 
        console.log( res.myColumn ); // == 250
    },
    "SELECT * FROM tblTest"
);

Promise:

let con = new odbc.Connection()
    .connect(connection.connectionString);
 
let r = async () => {
    await con.prepareQuery("CREATE TABLE tblTest( myColumn int )").toSingle();
    await con.prepareQuery("INSERT INTO tblTest( myColumn )VALUES(?)", 250).toSingle();
    let r = await con.prepareQuery("SELECT * FROM tblTest").toSingle();
 
    console.log( r.myColumn ); // == 250
};
 
r().then(() => {
 
}).catch((err) => {
    console.log( err );
});
