[−][src]Struct google_spanner1::ResultSetMetadata
Metadata about a ResultSet or PartialResultSet.
This type is not used in any activity, and only used as part of another schema.
Fields
row_type: Option<StructType>
Indicates the field names and types for the rows in the result
set. For example, a SQL query like "SELECT UserId, UserName FROM Users"
could return a row_type
value like:
"fields": [
{ "name": "UserId", "type": { "code": "INT64" } },
{ "name": "UserName", "type": { "code": "STRING" } },
]````
transaction: Option<Transaction>
If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here.
