# MathUpdate

## Description

The MathUpdate element in transaction math indicates an activity that processes projections, and makes only "virtual" database updates.The actual results of projection processing are maintained in memory only, and no database contents are modified. As each successive calculation is performed, the results of preceding calculations are not retrieved from the database, but from memory instead (except for math elements that always retrieve directly from the database).

Notes:

- ObjectLoop and MathLoop types, and OBJECTFIELD math variables, always access the database directly, and do not reference field values in memory.

- Math variables of type SegmentField within Calculate rules do not support projection processing.

- ScreenMath is not included in projection processing.

MathUpdate Element/Attribute Table
Element | Definition | Attribute | Values
--- | --- | --- | ---
<MathUpdate> | Holds the math variable to copy into the named table field in memory. |  | Required element value: Text Specifies a math variable name (for all data types). The variable name must be one of those specified in MathVariables preceding the MathUpdate element in the configuration.
| FIELDNAME | Required attribute: Text Specifies the name of the Policy or Segment field to update in memory.
| TYPE | Required attribute: "POLICYFIELD", "SEGMENTFIELD" or SEGMENTFIELDCOLLECTION" Identifies the table to update in memory. SegmentFieldCollection will update the named Segment Field records with the collection values.
| SEGMENTGUID | A math variable containing a SegmentGUID Required only if TYPE equals SEGMENTFIELD. Identifies the segment record to update.

## XML Example

    <MathVariable VARIABLENAME="PolicyTextMV" TYPE="FIELD" DATATYPE="TEXT">Policy:TestField</MathVariable>

    <MathVariable VARIABLENAME="TextMV" TYPE="VALUE" DATATYPE="TEXT">Test2</MathVariable>

    <MathUpdate FIELDNAME="PolicyTextField2" TYPE="POLICYFIELD">TextMV</MathUpdate>

    <MathVariable VARIABLENAME="IntegerMV" TYPE="VALUE" DATATYPE="INTEGER">2</MathVariable>

    <MathUpdate FIELDNAME="PolicyIntegerField2" TYPE="POLICYFIELD">IntegerMV</MathUpdate>

    <MathVariable VARIABLENAME="SegmentGUIDMV" TYPE="SQL" DATATYPE="TEXT">SELECT SegmentGUID...</MathVariable>

    <MathVariable VARIABLENAME="TextMV" TYPE="VALUE" DATATYPE="TEXT">Test2</MathVariable>

    <MathUpdate FIELDNAME="SegmentTextField1" TYPE="SEGMENTFIELD" SEGMENTGUID="SegmentGUIDMV">TextMV</MathUpdate>

    <MathVariable VARIABLENAME="IntegerMV" TYPE="VALUE" DATATYPE="INTEGER">2</MathVariable>

    <MathUpdate FIELDNAME="SegmentIntegerField2" TYPE="SEGMENTFIELD" SEGMENTGUID="SegmentGUIDMV">IntegerMV</MathUpdate>

    <MathVariable VARIABLENAME="SegmentGUIDCollection" TYPE="COLLECTION" DATATYPE="MAP">SELECT SegmentGUID, Value... </MathVariable>

    <MathUpdate FIELDNAME="SegmentTextField2" TYPE="SEGMENTFIELDCOLLECTION">SegmentGUIDCollection</MathUpdate>
