Database Table

This page is for data modellers who want to configure a database table.

Overview

From a PhixFlow datasource, you can open a window listing the tables in that database. For example, in the datasource properties tab, in the toolbar click on  Show Tables. The list shows the tables that the users defined in the datasource instances have permission to view. For each table, you can display:

  • the data in the table
  • a list of the attributes defined in that table

Depending on where you open the table list from, it will be either a simple list with only the name of each table, or a detailed list.

The database tables list has a toolbar with common buttons. You can export data from a detailed list using the  Download data to file button.

Property Pane Toolbar

For information about the toolbar options, see the Common Properties page, Toolbars and Controls section.

Detailed Table List

In the detailed table list, the following fields are shown for each table:

FieldDescription
OwnerThe table owner
NameThe name of the table
Tablespace NameThat tablespace this table is contained in
RowsApproximate number of rows in this table. Note that this information is based on stats collected by the database, and in some cases may not be fully up-to-date.

You can do the following things:

  • To show data in table, double-click on the table.
  • To display a simple list of the table attributes, right-click to display the context menu and select Show Table Attributes.
  • To display a detailed list of attributes, right-click and select Show Attribute Details; see Table Attribute Details below.
  • To export data from a table, use the  Download data to file button; see Download CSV or Excel Data.
  • To create a collector for the table: 
    • either drag the table onto a model view
    • or right-click and select Create a Collector.

Table Attribute Details 

Depending on how you display them, database table attributes may be

  • either in a simple list, with only the name of each attribute
  • or in  detailed list.

In the detailed list, the following fields are shown for each attribute:

FieldDescription
TABLENAMEThe name of the table.
COLUMNIDThe internal id for the column.
COLUMNNAMEThe name of the attribute
DATATYPEThe data type.
CHARLENGTHFor character types, the column length in characters (not necessarily the same as the length in bytes depending on character sets).
DATAPRECISIONFor numeric types, the data precision.
DATASCALEFor numeric types, the data scale.
NULLABLEWhether or not the column allows null values.
DEFAULTLENGTHThe default length of the column.

You can select several attributes and drag them onto a model window. PhixFlow creates a database collector to read the selected fields from that table.
