Viewing Records and Fields

Viewing Records and Fields

You can view one or more records in a data map, and fields in each record.
Each record appears in its own
Record
window. A
Record
window displays the record name and the fields in the record.
To view records and fields:
  1. Open the data map.
  2. On the
    Data Map
    tab in the
    Resource Explorer
    , complete one of the following actions:
    • To view a single record, double-click the record.
    • To view multiple records, each in a separate
      Record
      window, right-click each record and click
      Explore
      .
    The
    Fields
    tab in a
    Record
    window displays the record name and the following information for each field:
    • Field name
    • Datatype
    • Precision, scale, and length values, in parentheses
    • If the field is defined as an array, the value
      ARRAY
      followed by the number of elements in the array
    • The decimal offset of the field within the record
    • The hexadecimal offset of the field within the record
    The
    Expr(
    n
    )
    tab in the
    Record
    window displays any user-defined fields. The
    n
    variable indicates the number of user-defined fields.
    Each row on the
    Expr(
    n
    )
    tab contains either a field definition or the assignment of a value to a defined field.
    The following table describes the columns that the
    Expr(
    n
    )
    tab displays for each field:
    Column
    Description
    Field status indicator
    Indicates the status of the field. The options are:
    • Check mark
      . The field is valid.
    • X
      . The field is not valid. The comment in the Validation column describes the type of error that the field contains..
    • Arrow
      . A new field is selected, after selecting one of the Add Field menu commands.
    Name
    The user-defined name for the field.
    Type
    The datatype of the field.
    Precision
    The precision of the field.
    Scale
    The scale of the field.
    Length
    The length of the field.
    Phase
    Indicates the type of database communication for the user-defined field. For example, if a field is defined with a phase of R, its expression is not recalculated when the database is being written to.
    The options are:
    • R
      . Read.
    • W
      . Write.
    • RW
      . Read and write.

      Move Field Up
      or
      Move Field Down
      .
    • To move the completed fields to the top of the list, right-click anywhere on the
      Expr(
      n
