Release Notes

Dear go-hdb users, please find a description of the main features of this release below. Going from 0.14.4 to 0.99 should indicate, that this is a huge step into the direction of a 1.0 release. So, while most effort was spent to prepare for 1.0 features like

this release brings some interesting and hopefully useful features as well:

Main Features

  1. Data Format Version.

    The so-called Data Format Version was increased, so that the following HANA data types will be recognized by the driver and correctly reported by https://golang.org/pkg/database/sql/#ColumnType.DatabaseTypeName

    • DAYDATE
    • SECONDTIME
    • LONGDATE
    • SECONDDATE
    • SHORTTEXT
    • ALPHANUM

  2. Usage of sql.Rows in Stored Procedures with table output parameters.

    Until now, table output parameter content was retrieved via a separate query call. As the Go sql package does now support sql.Rows in Rows.Scan, the workaround via a separate query call is obsolete. Nonetheless, like this change is incompatible compared to the former releases, the feature needs to be opted in. To support a smooth transition, procedure calls works per default like in the past (legacy mode). Anyway, the use of 'separate queries' is deprecated and the default is going to be changed within the next releases. Release 1.0 will only support the new version of retrieving table output parameter content, so new projects based on (go-hdb)[https://github.com/SAP/go-hdb] should opt in the feature already now:

    • please use a Connector object to open a database
    • please set the legacy mode via the Connector object to false
    connector, err := NewDSNConnector(TestDSN)
if err != nil {
  log.Fatal(err)
}
// *Switch to non-legacy mode.
connector.SetLegacy(false)
db := sql.OpenDB(connector)
defer db.Close()

    For a complete example please see Example_callTableOut.
