Table Preview

This panel includes several subpanels that provide more information on your selected table.

 

A. Row Count and Row Limit Configuration

Displays the number of rows in the data source.

 

B. Column Information

This panel displays a list of the columns in the table currently in preview, their data type, number of unique values, and number of missing values (nulls or blanks).

You can sort the columns of the selected table by name or type by clicking the Sort  icon located to the right of the corresponding sort option. 

You can modify load options for specific file types (e.g., HTML, Microsoft Excel, Microsoft Access, delimited text) by clicking on the Load Options button. 

When previewing HTML tables, clicking on the Text Viewer  icon displays a dialog showing the HTML style code of the table.

Clearing the checkbox beside a column removes it from the table when loaded in the Prepare window. Thus, when the table is loaded, this column will not be displayed.

Clicking the Filter  icon beside a column expands the Filters pane and allows you to define various filters depending on the column's data type. Filters applied to the columns of a table in the Preview window are applied to the table when loaded into the Prepare window.  

 

C. Column Statistics

When a column is selected in the Column Information subpanel, all unique values of that column, as well as various statistics according to data type, display in the Column Statistics subpanel.

File information is also displayed for file-based data sources. 

 

D. Filters

This subpanel can be expanded or collapsed by clicking the Filters button. When expanded, it displays a list of all filters applied to a selected table.

 

E. Data Preview

The Data Preview subpanel displays sample rows from the selected table. This subpanel allows you to visually confirm whether the data you need are in the table you selected.

Icons on the header readily tell you a column's data type:

  •  Date/Time
  •  Number
  •  Text

If your table is especially wide, you can filter for specific columns using the column filter control.
