#row_type ⇒ ::Google::Cloud::Spanner::V1::StructType

Returns 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" } },
].

Returns:

  • (::Google::Cloud::Spanner::V1::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" } },
]

#undeclared_parameters ⇒ ::Google::Cloud::Spanner::V1::StructType

Returns 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" } },
].
