impl<'a> FromSql<'a> for ScalarImplTiberiusWrapper

The following table shows the mapping between Rust types and Sql Server types in tiberius. |Rust Type|Sql Server Type| |u8|tinyint| |i16|smallint| |i32|int| |i64|bigint| |f32|float(24)| |f64|float(53)| |bool|bit| |String/&str|nvarchar/varchar/nchar/char/ntext/text| |Vec<u8>/&[u8]|binary/varbinary/image| |Uuid|uniqueidentifier| |Numeric|numeric/decimal| |Decimal (with feature flag rust_decimal)|numeric/decimal| |XmlData|xml| |NaiveDateTime (with feature flag chrono)|datetime/datetime2/smalldatetime| |NaiveDate (with feature flag chrono)|date| |NaiveTime (with feature flag chrono)|time| |DateTime (with feature flag chrono)|datetimeoffset|

See the time module for more information about the date and time structs.

impl<'a> IntoSql<'a> for ScalarImplTiberiusWrapper

The following table shows the mapping between Rust types and Sql Server types in tiberius.

Rust typeSql Server type

f64float(53)

NaiveDate (with chrono feature, TDS 7.3 >)date

DateTime (with chrono feature, TDS 7.3 >)datetimeoffset
NaiveDateTime (with chrono feature, TDS 7.3 >)datetime2
NaiveDateTime (with chrono feature, TDS 7.2)datetime

It is possible to use some of the types to write into columns that are not of the same type. For example on systems following the TDS 7.3 standard (SQL Server 2008 and later), the chrono type NaiveDateTime can also be used to write to datetime, datetime2 and smalldatetime columns. All string types can also be used with ntext, text, varchar, nchar and char columns. All binary types can also be used with binary and image columns.

See the time module for more information about the date and time structs.
