grid

column. You can open attribute properties from:

Field Description

Name

Enter the name of the attribute.

Tip
PhixFlow recognises the attribute name `UID` as a unique identifier for a record. As records are added, PhixFlow automatically increments the UID value.

Type

Select the type of data this attribute contains; see Understanding Data Types.

String
Bigstring
Integer
Float
Decimal
Date
Datetime
Graphic
TrueFalse

Length

This field is available when Type is String. By default strings are 50 characters long. Optionally specify a different string length of between 1 and 4000.

For strings longer than 4000 characters, set a Type of Bigstring.

Precision

This field is available when Type is Integer. Enter the maximum number of digits allowed in whole numbers. By default, integers are 10 digits long. Optionally specify a different integer precision of between 1 digit and 38 digits.

Significant Figures

This field is available when Type is Decimal. Enter the maximum number of total digits for decimal numbers. By default decimals have 10 significant figures.

To specify numbers must have two digits before and after the decimal point, such as 12.34, enter:

Significant Figures 4

Decimal Places 2

Decimal Places

This field is available when Type is Decimal. Enter the maximum number of digits allowed after the decimal point. By default, decimals have 2 decimal places.

This must be less than the number of significant figures.

FieldDescription

calculation, but you do not need to keep the result.

Order

The order of the attributes in the stream. Attribute expressions are evaluated in this order.

This is important when you need to use the results of a calculation in another attribute:

either in its expression
or in a $ variable.

In the attribute list, the attribute that calculates the result must come before the attribute that requires the result.

ExpressionThe expression used to generate the attribute value. This is written as a PhixFlow Expression. It must evaluate to a single value, of the type specified in the Type field.

Note
Local attributes should not be used to back fields on forms or cards.

Indexed

Insert excerpt

	_check_box_untick
	_check_box_untick
nopanel	true

to prevent this attribute being indexed in the PhixFlow database.

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to index this attribute in the PhixFlow database.

To improve performance, index an attribute when the

stream

table has a large data set and an output pipe from the

stream

table uses this attribute to:

filter the

stream

data
sort or group the

stream

data.

Filter conditions are
case-independent by default

Note: Attributes with the type, Bigstring, cannot be indexed as this is not supported by the underlying database.

Primary Key

Insert excerpt

	_check_box_

untick

tick
	_check_box_

untick

tick
nopanel	true

to use filters that are case-sensitive.

indicates this attribute is a primary key. Primary keys contain a unique identifier for every record in the table.

Note: Attributes with the type, Bigstring, cannot be set as the primary key as this is not supported by the underlying database.

Secondary Key

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to set new filter conditions on this attribute to be case-insensitive by default. The filter window → Ignore Case check box inherits this setting; see Filters on Data Views. For case-insensitive filters, there is no difference if the attribute is also indexed. NoteThis option affects the behaviour of filters for PhixFlow instances running on Oracle or MariaDB (MySQL) databases.
For PhixFlow instances running on a SQL Server database, filters are always case-independent.

indicates this attribute is a secondary key. Secondary keys are optional keys that index records and do not have to be unique.

Foreign Key

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

indicates this attribute is a foreign key. This means the ERD links this attribute to a primary key attribute in an other table; see Entity Relationship Diagrams.

Info
Table attributes that are flagged as a Foreign Key are automatically considered to be Indexed.

Display Name

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

indicates the name of this attribute is used as the label rather than the primary key attribute name.

Order

The order of the attributes in the table. Attribute expressions are evaluated in this order.

This is important when you need to use the results of a calculation in another attribute:

either in its expression
or in a $ variable.

In the attribute list, the attribute that calculates the result must come before the attribute that requires the result.

Expression

The expression used to generate the attribute value. This is written as and expression; see Expressions and PhixScripts. It must evaluate to a single value, of the type specified in the Type field.

Available when Basic Settings → Type is String or Bigstring.

Insert excerpt

	_check_box_untick

to ignore this attribute when translating text in PhixFlow (the default).

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to include this attribute when translating text that appears in PhixFlow. To be translated, the attribute text must be included in a translation

stream

table; see Translating an Application Interface and Translation Table.

Filter conditions are case-sensitive by default

This field is only available for PhixFlow instances running on Oracle or MySQL databases.

Available when Basic Settings → Type is String or Bigstring.

Insert excerpt

	_check_box_untick
	_check_box_untick
nopanel	true

to use filters that are case-sensitive.

Insert excerpt

	_check_box_tick
	_check_box_tick
nopanel	true

to set new filter conditions on this attribute to be case-insensitive by default. The filter window → Ignore Case check box inherits this setting; see Filters on Data Views. For case-insensitive filters, there is no difference if the attribute is also indexed.

Excerpt

name	caseSensitiveDatabase

Note
For PhixFlow instances running on a SQL Server database, filters are always case-insensitive.

Cache Key

Enter an expression to be evaluated for each

stream-item (

record

)

in the

stream

table . The expression can:

either use the value of this attribute
or calculate a different value

Once calculated, the cache key value persists throughout subsequent

stream

calculation, rather than being created from scratch for each

stream-item

record as normal. This allows you to keep track of the calculation as it progresses.

This means you can use a "persistent" attribute value in other expressions.
