class Google::Apis::SpannerV1::Statement

A single DML statement.

Attributes

param_types[RW]

It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type `BYTES` and values of type `STRING` both appear in params as JSON strings. In these cases, `param_types` can be used to specify the exact SQL type for some or all of the SQL statement parameters. See the definition of Type for more information about SQL types. Corresponds to the JSON property `paramTypes` @return [Hash<String,Google::Apis::SpannerV1::Type>]

params[RW]

Parameter names and values that bind to placeholders in the DML string. A parameter placeholder consists of the `@` character followed by the parameter name (for example, `@firstName`). Parameter names can contain letters, numbers, and underscores. Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example: `“ WHERE id > @msg_id AND id < @msg_id + 100”` It is an error to execute a SQL statement with unbound parameters. Corresponds to the JSON property `params` @return [Hash<String,Object>]

sql[RW]

Required. The DML string. Corresponds to the JSON property `sql` @return [String]
