Overview

Tables are a key model component. They represent a structured store of data within PhixFlow receiving data from one or more components, processing it then storing it. When you make changes to tables and attributes, PhixFlow automatically publishes them to the database; see Publishing Tables.

Analysis Options

Field Description

Enabled

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to include the table during analysis runs.

Static Data

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to set the table to hold static data. Static data is reference or "look up" data that is used as part of a table calculation.

Updating a static table

In general, static tables are not updated during an analysis run that is initiated on another table in the model. The exception is when an incoming push pipe is triggered, as this will force the table to update itself.

Instead, to update the data in a static table you must run analysis directly on the table via:

the model
a task plan.

Period

Select the time period for the table:

Excerpt

name	Period

Transactional

This allows multiple users to run independent analysis tasks at the same time.

Daily

This is a non-transactional table type, and generates or collects data every day.

Monthly

This is a non-transactional table type, and generates or collects data every month.

Variable

This is a non-transactional table type, and generates or collects data since the more recent run of the table to the current date.

As transactional tables need a UID attribute, PhixFlow automatically creates this attribute if it does not already exist.

Default Data Range

This option affects the following items for which this is the backing table:

views
screens
card components.

Insert excerpt

	_data_range
	_data_range
nopanel	true

If no option is is selected, PhixFlow assumes the default data range is All.

You can override this setting using the options Use Custom Data Range and Data Range available:

on a Screen.
on a card; see Component.

You cannot override this setting for a view.

Table Type

Select the table type; see Types of Table and When to Use Them. The type indicates the function that operates on the data.

Aggregate Table
Calculate Table
CalculateBySet Table
Cartesian Table
Merge Table

Supersede Items on Pipe

Select a loop pipe from the list of those available.

A loop pipe links the table back to itself. It compares new data records to the existing data records. If there is a repeated record PhixFlow uses the new one in the table and marks the old one as superseded.

Input Multiplier

The input multiplier expression should evaluate to a list of one or more values. For each value in the list, the internal variable _inputMultiplier will be set to that value and the whole table processing will be repeated i.e. the pull pipes will be read and the data from those pipes processed to generate output records to be added to the current recordset. For example :

do ( $aRange = [], addElement($aRange, rng.RangeFrom), addElement($aRange, rng.RangeTo), $bRange = [], addElement($bRange, $aRange), $bRange )

Where rng.RangeFrom = 500 and rng.RangeTo = 1000, the above example evaluates to [[500,1000]], which is a list containing 1 element, which is itself a list containing 2 elements. An input multiplier that evaluates to [3,4,7,8] would run the Table 4 times.
Because Input Multipliers are evaluated first in the PhixFlow Timing Cycle they are often used to look up values that can be passed to Database or other Collectors.

See Expressions and PhixScripts.

Log Input Multiplier Messages

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to cause PhixFlow to write a message to the log every time an Input Multiplier value changes during an analysis run.

Output Multiplier

This field is an expression which should evaluate to an array of values. A separate output record will be produced for each value in the array and this value is available as _outputMultiplier in each of the table output attribute expressions (each value in the array is also available through _type, although this is not recommended usage). In effect this will multiply each of the output records by the number of elements from the returned list.
For example :

ifNull(in.ASSET, [1,10,12] , // else do [5,7] )

will create 3 records for every record in the table if in.ASSET contains a value (setting _type = 1, 10 and 12 in each case). Otherwise it will create 2 records for every record in the table (and set _type = 5 and 7). An output multiplier may also evaluate to a record, or a group of records. For example an Output Multiplier with the expression:

do( lookup(lkin, $num = in.BNumber), lkin )

will return a list of records which match the lookup on the lkin pipe. In this case the required data can be extracted from the Output Multiplier using the following expression :

do ( $values = _type, $values.account_num )

If the output multiplier expression evaluates to _NULL, an empty list of values or an empty list of records then a single output record will be produced with _type set to _NULL, _NULL or an empty record respectively.

See Expressions and PhixScripts.

Select Records to Output

(Formerly Output Filter)

You can select a subset of records to output to the next modelling object. You select records using the data in any attribute that is in the table output. Enter an expression that should evaluate to true or false (equivalently 1 or 0).

When the expression evaluates to true or 1, the records found by the expression are selected and output to the next modelling object.

For example:

A table containing data about accounts has an attribute called "active".
You only want to include "active" accounts in the following tables.
Active accounts have the value 1.

To select active accounts, enter the expression _out.active.
All records that have the active attribute set to any other value are ignored.

See Expressions and PhixScripts.

Warning

We recommend that you always specify the data retention values for every table you create.
PhixFlow checks that a table has:

either data retention settings (recommended)
or Retain All Data selected.

If no data retention option is set, PhixFlow displays an error in the Errors section, above.

Using Tasks and Task Plans for information about tasks.

Field

Description

What Data is Deleted

Retain All Data

Insert excerpt

	_check_box_untick
	_check_box_untick
nopanel	true

to specify the criteria for keeping data in the Keep... properties below (recommended).

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to allow old data to accumulate in PhixFlow.

Warning
Tables with Retain All Data ticked never have their data deleted and the data will accumulate. This can lead to performance issues.

Keep for N Days

Anchor

	keepForXDays
	keepForXDays

Enter the number of days to keep data in the table.

The age of data in a recordset is its 'to' date, relative to the 'to' date of the newest valid recordset in the table .

When a table-data-delete task runs for a table and:

Keep for X Days only is set, PhixFlow deletes table data that is older than N days.
Keep for Y Recordsets only is set, PhixFlow keeps the most recent X recordsets and deletes recordsets that exceed X.
both Keep for X Days and Keep for Y Recordsets are set, PhixFlow deletes the table data that meets both conditions.
neither Keep for N Days nor Keep for X Recordsets are set, PhixFlow keeps table data indefinitely. This can lead to performance issues.

Keep for X Recordsets

The number of recordsets to keep in the table.

Keep Superseded for N Days

Anchor

	keepSupersededForXDays
	keepSupersededForXDays

Available when Track Superseded Data is selected.

Enter the number of days to keep superseded records in the table data.

Tip

Remember to keep superseded records for as long as you want the option to roll back the data.

For example, when Keep Superseded for N Days is set to 4, you can run roll back on data that was superseded up to 4 days ago.

A table-data-delete task removes superseded records older than 4 days, so PhixFlow no longer has the data to be able to roll it back.

In a table where the superseded date is tracked, the table data contains a mixture of active records and records that have been superseded.

When a table-data-delete task runs for a table and:

Keep Superseded for N Days only is set, PhixFlow deletes data records that were superseded more than N days ago.
Keep Superseded for X Recordsets only is set, PhixFlow deletes superseded records from the recordsets that exceed X.
both Keep Superseded for N Days and Keep Superseded for X Recordsets are set, PhixFlow deletes the superseded records that meet both conditions.
neither Keep Superseded for N Days nor Keep Superseded for X Recordsets are set, PhixFlow keeps superseded records indefinitely. This can lead to performance issues.

Keep Superseded for X Tablesets

Available when Track Superseded Data is selected.

Enter the number of recent recordsets that will retain their superseded data records.

Field Description

Advanced Properties Only use this field with advice from PhixFlow support.

Database View

Use this property if your database administrator wants to query table data in the PhixFlow database.

Enter a string in the format v_xxxx. When the table is published to the database, PhixFlow creates a view. If the table is deleted, the next system task that runs will clear the associated view from the database.

By default, this field is blank and no view is created in the database.

Audit Manual Changes

This toggle is available when the Analysis Options → Period is Transactional.

Insert excerpt

	_toggle_on
	_toggle_on
nopanel	true

toggle on to update and delete initiated by actions (not those carried out by analysis runs) will automatically mark the existing record as superseded and create a new recordset. The new versions of the updated records will be placed in the new recordset. Inserts will simply create a new recordset, and add the inserted record into that recordset.

When Audit Manual Changes is first set, the attributes UpdateAction, UpdatedByName, UpdatedByID and UpdatedTime will be created if they do not already exist. If you do not require these attributes, delete them. For the UpdatedByName attribute, PhixFlow creates a field of 250 characters.

UpdateAction must be set to the type of action, such as INSERT, UPDATE or DELETE. The other attributes will be populated if they exist on the table:

UpdatedByName - the name of the user that performed the update,
UpdatedByID - the internal id of the user that performed the update
UpdatedTime - the date and time the update was made

Storage Options

Index Scheme

Anchor

	index_scheme
	index_scheme

Select an option to determine how indexes on the table are organised.

All: indexes on the table are optimised for selecting from all recordsets (non-historied reads).
Latest: indexes on the table are optimised for selecting from the latest recordset (i.e. for historied reads).
Superseded: indexes on the table are optimised for self-updating tables which have a mostly superseded records.
None: no indexes are created on the table.
Partitioned: this index scheme is specific to partitioned tables; see Storage Type below. Partitioned tables must use this index scheme, and only partitioned tables can use it.

Storage Type

Select an option to specify how data for the table should be stored:

Database: Store the data in a regular table within the PhixFlow database. This is the most common option
Database (Partitioned): Store the data in a partitioned table within the PhixFlow database. This option provides improved performance for rollback and retaining very large recordsets. The option is only available if "partitioning" is available within your database installation.
In Memory: Data for the table will not be written to the database. This option can be used (for example) when you want to aggregate large amounts of unsorted data which can then be written to a stored table.

Data Generation Options

Anchor

	data-gen
	data-gen

Start Date

Enter the date on which this table starts or click

Insert excerpt

	_calendar
	_calendar
nopanel	true

to select a date. Data will be populated into the table from this date onwards.

Primary Key Generator

This option relates to an actionflow with a save node that inserts a new record into a table. Each new record requires a unique value for the record's primary key. Use this option to specify how PhixFlow generates the primary key value.

Internal: PhixFlow generates unique primary key values automatically. This is equivalent to setting the attribute expression to _NULL.
Sequence: display the Primary Key Generator Sequence option, in which you can select a sequence of values.

Primary Key Generator Sequence

Available when Primary Key Generator is Sequence.

Select a sequence to assign a new value to the primary key attribute of a new record; see Sequence.

The new record takes the next primary key value in a sequence. This is equivalent to setting the attribute expression to nextValue("sequenceName".

In Memory Cache Size Enter the size of the cache that will be maintained when you are using an in-memory table. See Manage Unsorted Data Using an In-Memory Table.

Allow Partial Set Processing

Insert excerpt

	_check_box_untick
	_check_box_untick
nopanel	true

to restrict all users to the Table Download Limit.

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

so that, when analysis reaches the end of a buffer block, it submits the candidate set for processing, even if the next buffer block has a different key.

Prevent Parallel Processing

Available when Period is Transactional.

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to ensure only a single recordset can be generated at a time even if the table receives several concurrent requests to generate data.

This can be useful where you want to make sure that two analysis runs do not attempt to update the same records at the same time e.g. as a result of two people selecting the same records in a view and then hitting the same action button at the same time to process those records.

Run Alone

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

so that, whenever the analysis engine needs to generate data for this table, it will first wait for all running tasks to complete before it starts.

Any additional analysis tasks submitted while this table is waiting to start, or while it is generating data, will wait until this table has completed its analysis before they start.

Key Tolerances When building a candidate set, data can be grouped together using a specific key value, e.g. Account Number. If the key value is a number, enter a key tolerance to identify numbers within the given tolerance as the same key value.

Default View Select the default view for the table; see Views for details of creating views on tables.

Last Run Date (Read only) PhixFlow displays the date and time that analysis was last run for this table. This date is taken from the "to date" of the most recent recordset for this table.

Last Run By PhixFlow displays the user that last ran analysis on this table.
