With Redshift ML, you can embed predictions like fraud detection, risk scoring, and churn prediction directly in queries and reports. Predictive analytics with Amazon Redshift Redshift ML automatically handles all the steps needed to train and deploy a model. Redshift ML then compiles and imports the trained model inside the Redshift data warehouse and prepares a SQL inference function that can be immediately used in SQL queries. To get started, use the CREATE MODEL SQL command in Redshift and specify training data either as a table or SELECT statement. Use ML on your Redshift data using standard SQL There is no need to manage a separate inference model end point, and the training data is secured end-to-end with encryption. Redshift ML provides simple, optimized, and secure integration between Redshift and Amazon SageMaker and enables inference within the Redshift cluster, making it easy to use predictions generated by ML-based models in queries and applications. Redshift ML makes the model available as a SQL function within your Redshift data warehouse so you can easily apply it directly in your queries and reports.īecause Redshift ML allows you to use standard SQL, it is easy for you to be productive with new use cases for your analytics data. For example, you can use customer retention data in Redshift to train a churn detection model and then apply that model to your dashboards for your marketing team to offer incentives to customers at risk of churning. Simply use SQL statements to create and train Amazon SageMaker machine learning models using your Redshift data and then use these models to make predictions. With Redshift ML, you can take advantage of Amazon SageMaker, a fully managed machine learning service, without learning new tools or languages. As noted, you need/want to have launched ms-access as administrator.Amazon Redshift ML makes it easy for data analysts and database developers to create, train, and apply machine learning models using familiar SQL commands in Amazon Redshift data warehouses. If that does not work, then try to create a Machine data source. Use access to create the new connection (do NOT launch the ODBC panel from the control panel).Īs noted, try first choosing to create a FILE connection. So, launch access (tap windows key, type in access, and then do NOT click on the result, but right click and choose run as administrator.Īt that point, choose from ribbon External data, ODBC database. However, I find a good number of drivers - even the sqlLite ones don't work (for some un-known reason) as FILE dsn, but do work when creating a SYSTEM dsn (A Machine data source). So, the default (tab) is a FILE dsn, and that is MUCH preferred. If that does not work, then try again and this time create a "Machine data source" I do suggest you try launching Access as administrator (the reason is the folders where the connection settings are saved often require elevated rights).įirst try creating a FILE DSN. It not clear how you attempting to link (using external data + the wizards to create a connection). This does suggest you have the correct ODBC drivers installed. However, if you able to get the ADO in VBA (in access working with a conneciton to redshift, then you KNOW that a valid driver does exist). Tdf.SourceTableName = ""Įdit-I've tried all three of the strConnectionString settings in the TestLinkingToRS() function 'strConnectionString = "DSN=CPP_RS UID=theUserID PWD=thePassword" 'strConnectionString = "Driver= Server= Database=theDatabase UID=theUserID PWD=thePassword Port=thePortNo" When I try to link the table using the code below I get an error stating "could not find installable ISAM" at the TableDefs.Append step. When I test using ?GetRSConn.Execute("SELECT * from tblTest").RecordCount in the immediate window I get the correct result. MsgBox Err.Number & vbCrLf & vbCrLf & Err.Description If IsEmpty(dbRSConn) Or dbRSConn Is Nothing Then Public Function GetRSConn(Optional ByVal TimeOut As Long = -1) As ADODB.Connection The dbRSConn variable is a private variable in the same module. I'm using Office 365 and version 2.00.00.06 of the Amazon Redshift ODBC Driver (圆4) When I try to programmatically create the linked table using VBA I get an error "could not find installable ISAM", about which I have been able to find very little information online If I try to link a table from Redshift to Access however using that DSN the Access app crashes every single time. I've created the DSN on my pc and I can connect with VBA using an nnection object and setting the connection string to the DSN. I've recreated just one table in Redshift so far for testing. I am testing out moving those tables to AWS Redshift. I have an MS Access app that has linked tables from a locally installed SQL Server Express instance on the same PC. Access cannot link to a table in AWS Redshift
