Inputs/Outputs

  • cfxdt.png type —

    specifies the data type into which you want to convert variant data.

  • cfxdt.png database variant —

    specifies the variant data you want to convert to the data type specified in type. You can wire a variant, a 1D array of variants, or a 2D array of variants to this input. Refer to the Details section of this topic for more information about using this input.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • ifxdt.png data —

    returns the resulting data type.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    • Database Variant To Data Details

    You can wire a variant, a 1D array of variants, or a 2D array of variants to the database variant input. Depending on the data type that you wire to the type and database variant inputs, this function performs the following different conversions:

    Data Type of "database variant" Data Type of "type"
    Cluster 1D Array of Non-Clusters 1D Array of Clusters 2D Array Others
    Variant This function converts the variant to the LabVIEW data type specified in type.
    1D Array of Variants Each element in the cluster defines a column. This function converts each element of the 1D array to a column in sequence. The output is a cluster. This function converts each element of the 1D array to the element data type specified in type. The output is a 1D array. This function converts each element of the 1D array to a cluster. The output is a 1D array of clusters. The wire of database variant is broken. The wire of database variant is broken.
    2D Array of Variants The wire of database variant is broken. The wire of database variant is broken. This function converts each row of the 2D array to a cluster. The output is a 1D array of clusters. This function converts each element of the 2D array to the element data type specified in type. The output is a 2D array. The wire of database variant is broken.
    Others The wire of database variant is broken.
