Name	Description
`row_type`	`google.cloud.spanner_v1.types.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`	`google.cloud.spanner_v1.types.Transaction` If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here.
`undeclared_parameters`	`google.cloud.spanner_v1.types.StructType` A SQL query can be parameterized. In PLAN mode, these parameters can be undeclared. This indicates the field names and types for those undeclared parameters in the SQL query. For example, a SQL query like `"SELECT * FROM Users where UserId = @userId and UserName = @userName "` could return a `undeclared_parameters` value like: :: "fields": [ { "name": "UserId", "type": { "code": "INT64" } }, { "name": "UserName", "type": { "code": "STRING" } }, ]
