Struct TokenAltMetaData 

pub struct TokenAltMetaData<'a> {
    pub id: u16,
    pub by_columns: Vec<u16>,
    pub columns: Vec<AltMetaDataColumn<'a>>,
}

The token describing the layout of a COMPUTE (BY) result set (ALTMETADATA, token 0x88).

A single query can contain more than one COMPUTE clause; each is uniquely identified by id, which the matching TokenAltRow rows refer back to. See MS-TDS section 2.2.7.1.

Fields

id: u16

Identifies the COMPUTE clause this metadata describes. The associated TokenAltRow rows carry the same id.

by_columns: Vec<u16>

The column numbers (from the originating result set) listed in the COMPUTE BY clause, in order.

columns: Vec<AltMetaDataColumn<'a>>

The computed columns, one per aggregate operator in the COMPUTE clause.
