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" } },
]
