    Last Modified: August 13, 2019

    Retrieves the double-precision, floating-point numeric value of the parameter you specify with the parameter index input.

    connector_pane_image
    datatype_icon

    command-recordset reference

    Reference that combines an ADO Command object and an ADO Recordset object. Use a Recordset object to read and manipulate data from databases.

    datatype_icon

    parameter index

    Ordinal index or the name of the parameter. The parameter index can be either the zero-indexed position of the parameter or the name of the parameter.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    datatype_icon

    value

    Double-precision, floating point data returned by the node.

    command-recordset reference out

    A reference that combines an ADO Command object and an ADO Recordset object. Use a Recordset object to read and manipulate data from databases.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
