Options for CommandGetSqlInfo.

Variants§

§

FlightSqlServerName = 0

Retrieves a UTF-8 string with the name of the Flight SQL Server.

§

FlightSqlServerVersion = 1

Retrieves a UTF-8 string with the native version of the Flight SQL Server.

§

FlightSqlServerArrowVersion = 2

Retrieves a UTF-8 string with the Arrow format version of the Flight SQL Server.

§

Retrieves a boolean value indicating whether the Flight SQL Server is read only.

Returns:

  • false: if read-write
  • true: if read only
§

FlightSqlServerSql = 4

Retrieves a boolean value indicating whether the Flight SQL Server supports executing SQL queries.

Note that the absence of this info (as opposed to a false value) does not necessarily mean that SQL is not supported, as this property was not originally defined.

§

FlightSqlServerSubstrait = 5

Retrieves a boolean value indicating whether the Flight SQL Server supports executing Substrait plans.

§

FlightSqlServerSubstraitMinVersion = 6

Retrieves a string value indicating the minimum supported Substrait version, or null if Substrait is not supported.

§

Retrieves an int32 indicating whether the Flight SQL Server supports the BeginTransaction/EndTransaction/BeginSavepoint/EndSavepoint actions.

Even if this is not supported, the database may still support explicit “BEGIN TRANSACTION”/“COMMIT” SQL statements (see SQL_TRANSACTIONS_SUPPORTED); this property is only about whether the server implements the Flight SQL API endpoints.

The possible values are listed in SqlSupportedTransaction.

§

FlightSqlServerCancel = 9

Retrieves a boolean value indicating whether the Flight SQL Server supports explicit query cancellation (the CancelQuery action).

§

Implementations§

source§

impl SqlInfo

source

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of SqlInfo.

source

pub fn from_i32(value: i32) -> Option<SqlInfo>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a SqlInfo, or None if value is not a valid variant.

source§

impl SqlInfo

source

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

source

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.
