Properties

Semantic type with an empty structure. | [NxMetaDef](https://help.qlik.com/en-US/sense-developer/November2024/Subsystems/EngineJSONAPI/Content/models-nxmetadef.htm) | | qName | Name of the variable.
The name must be unique.
This parameter is mandatory. | String | | qComment | Comment related to the variable.
This parameter is optional. | String | | qNumberPresentation | Sets the formatting of a field.
The properties of *qFieldAttributes* and the formatting mechanism are described below.

Formatting mechanism

The formatting mechanism depends on the type set in *qType,* as shown below:

Information note

In case of inconsistencies between the type and the format pattern, the format pattern takes precedence over the type.

Type is DATE, TIME, TIMESTAMP or INTERVAL

The following applies:

If a format pattern is defined in qFmt , the formatting is as defined in qFmt .
If qFmt is empty, the formatting is defined by the number interpretation variables included at the top of the script ( TimeFormat , DateFormat , TimeStampFormat ).
The properties qDec , qThou , qnDec , qUseThou are not used.

Type is INTEGER

The following applies:

If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the formatting mechanism uses the number interpretation variables included at the top of the script ( DecimalSep and ThousandSep ).
If no format pattern is defined in qFmt , no formatting is applied. The properties qDec , qThou , qnDec , qUseThou and the number interpretation variables defined in the script are not used .

Type is REAL

The following applies:

If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the engine uses the number interpretation variables included at the top of the script ( DecimalSep and ThousandSep ).
If no format pattern is defined in qFmt , and if the value is almost an integer value (for example, 14,000012), the value is formatted as an integer. The properties qDec , qThou , qnDec , qUseThou are not used.
If no format pattern is defined in qFmt , and if qnDec is defined and not 0, the property qDec is used. If qDec is not defined, the variable DecimalSep defined at the top of the script is used.
If no format pattern is defined in qFmt , and if qnDec is 0, the number of decimals is 14 and the property qDec is used. If qDec is not defined, the variable DecimalSep defined at the top of the script is used.

Type is FIX

The following applies:

If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the engine uses the number interpretation variables included at the top of the script ( DecimalSep and ThousandSep ).
If no format pattern is defined in qFmt , the properties qDec and qnDec are used. If qDec is not defined, the variable DecimalSep defined at the top of the script is used.

Type is MONEY

The following applies:

If a format pattern is defined in qFmt , the engine looks at the values set in qDec and qThou . If these properties are not defined, the engine uses the number interpretation variables included at the top of any script ( MoneyDecimalSep and MoneyThousandSep ).
If no format pattern is defined in qFmt , the engine uses the number interpretation variables included at the top of the script ( MoneyDecimalSep and MoneyThousandSep ).

Type is ASCII

No formatting, *qFmt* is ignored. | [FieldAttributes](https://help.qlik.com/en-US/sense-developer/November2024/Subsystems/EngineJSONAPI/Content/models-fieldattributes.htm) | | qIncludeInBookmark | Set this property to true to update the variable when applying a bookmark. The variable value will be persisted in the bookmark.
The value of a variable can affect the state of the selections.
Script variables cannot be persisted in the bookmark.
The default value is false. | Boolean | | qDefinition | Definition of the variable. | String |
