• #begin ⇒ ::Google::Cloud::Spanner::V1::TransactionOptions

  Begin a new transaction and execute this read or SQL query in it.

• #id ⇒ ::String

  Execute the read or SQL query in a previously-started transaction.

• #single_use ⇒ ::Google::Cloud::Spanner::V1::TransactionOptions

  Execute the read or SQL query in a temporary transaction.

Instance Attribute Details

#begin ⇒ ::Google::Cloud::Spanner::V1::TransactionOptions

Returns Begin a new transaction and execute this read or SQL query in it. The transaction ID of the new transaction is returned in ResultSetMetadata.transaction, which is a Transaction.

Note: The following fields are mutually exclusive: begin, single_use, id. If a field in that set is populated, all other fields in the set will automatically be cleared.

Returns:

• (::Google::Cloud::Spanner::V1::TransactionOptions) —

  Begin a new transaction and execute this read or SQL query in it. The transaction ID of the new transaction is returned in ResultSetMetadata.transaction, which is a Transaction.

  Note: The following fields are mutually exclusive: begin, single_use, id. If a field in that set is populated, all other fields in the set will automatically be cleared.

#id ⇒ ::String

Returns Execute the read or SQL query in a previously-started transaction.

Note: The following fields are mutually exclusive: id, single_use, begin. If a field in that set is populated, all other fields in the set will automatically be cleared.

end

#single_use ⇒ ::Google::Cloud::Spanner::V1::TransactionOptions

Returns Execute the read or SQL query in a temporary transaction. This is the most efficient way to execute a transaction that consists of a single SQL query.

Note: The following fields are mutually exclusive: single_use, id, begin. If a field in that set is populated, all other fields in the set will automatically be cleared.

Returns:
