StateDMI / Command / NewTable

Overview

The NewTable command creates a table with named columns, each of which is a specified data type. Tables are used to hold information about data objects. Tables can be written as final data products or artifacts of processing. Characteristics of the table are as follows:

  • Each column can only contain a single data type
  • The default precision for numbers for display and output is 2 digits after the decimal – additional formatting features may be available in write commands and may be added later
  • Tables are referenced using the TableID parameter
  • Cells in tables are referenced using the column name and cell values that identify rows (such as time series identifiers)

Command Parameters

Parameter             Description Default          
TableID
required		 Identifier for the table – should be unique among tables that are defined. Can be specified using processor ${Property}. None – must be specified.
Columns The column names and data types are defined using the format ColumnName,DataType; ColumnName,DataType. Column names can contain spaces; however, simple short names are generally handled better by display features and minimize errors in referencing the columns. Data types are specified using the following strings:
  • datetime – date and time
  • double – double precision number
  • float – single precision number
  • integer – integer (-2147483648 to 2147483647)
  • short – short integer (-32768 to 32767)
  • string – Unicode string
 No columns will be defined.
