ARMultiSchemaFieldFuncStruct

Identifies the column of interest and indicates the type of aggregation to use. The associated list structure, ARMultiSchemaFieldFuncList, allows specifying more than one field and/or aggregation function.


typedef struct ARMultiSchemaFieldFuncStruct { /* New */
    ARNameType               queryFromAlias;
    ARInternalId             fieldId;
    Int                      funcId;
} ARMultiSchemaFieldFuncStruct;

This structure has these elements:

Element

Description

queryFromAlias

Alias of the form to which the field belongs. (Aliases are defined in the ARMultiSchemaQueryFromStruct structure.)

Note

Because the ARGetListEntryWithMultiSchemaFields function can operate on multiple forms, each field must be qualified with a form name.

fieldId

Internal ID of the specified field (For information about field IDs, see Finding fields by label, name, or ID).

funcId

Type of aggregation to use. The possible values for the funcId member are:


#define AR_MULTI_SCHEMA_FUNC_NONE         0
#define AR_MULTI_SCHEMA_FUNC_MAX          1
#define AR_MULTI_SCHEMA_FUNC_MIN          2
#define AR_MULTI_SCHEMA_FUNC_AVG          3
#define AR_MULTI_SCHEMA_FUNC_SUM          4
#define AR_MULTI_SCHEMA_FUNC_COUNT        5
