      • hasRowType

        boolean hasRowType()
         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" } },
     ]
        .google.spanner.v1.StructType row_type = 1;
        Returns:
        Whether the rowType field is set.

      • getRowType

        StructType getRowType()
         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" } },
     ]
        .google.spanner.v1.StructType row_type = 1;
        Returns:
        The rowType.

      • getRowTypeOrBuilder

        StructTypeOrBuilder getRowTypeOrBuilder()
         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" } },
     ]
        .google.spanner.v1.StructType row_type = 1;

      • hasTransaction

        boolean hasTransaction()
         If the read or SQL query began a transaction as a side-effect, the
 information about the new transaction is yielded here.
        .google.spanner.v1.Transaction transaction = 2;
        Returns:
        Whether the transaction field is set.

      • getTransaction

        Transaction getTransaction()
         If the read or SQL query began a transaction as a side-effect, the
 information about the new transaction is yielded here.
        .google.spanner.v1.Transaction transaction = 2;
        Returns:
        The transaction.

      • getTransactionOrBuilder

        TransactionOrBuilder getTransactionOrBuilder()
         If the read or SQL query began a transaction as a side-effect, the
 information about the new transaction is yielded here.
        .google.spanner.v1.Transaction transaction = 2;

      • hasUndeclaredParameters

        boolean hasUndeclaredParameters()
         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" } },
     ]
        .google.spanner.v1.StructType undeclared_parameters = 3;
        Returns:
        Whether the undeclaredParameters field is set.

      • getUndeclaredParameters

        StructType getUndeclaredParameters()
         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" } },
     ]
        .google.spanner.v1.StructType undeclared_parameters = 3;
        Returns:
        The undeclaredParameters.

      • getUndeclaredParametersOrBuilder

        StructTypeOrBuilder getUndeclaredParametersOrBuilder()
