DirectionalDbParamCache(ParameterDirection, DbType, bool?)

Represents metadata for directional fixed-type database parameters (e.g., Integers, Booleans)

public DirectionalDbParamCache(ParameterDirection direction, DbType type, bool? hasDefault = null)

Parameters

direction ParameterDirection

type DbType

hasDefault bool?

Fields

Direction

public readonly ParameterDirection Direction

Field Value

ParameterDirection

Type

public readonly DbType Type

Field Value

DbType

Methods

Get(ParameterDirection, DbType, bool)

Gets the shared cached metadata for an unsized directional parameter shape.

public static DirectionalDbParamCache Get(ParameterDirection direction, DbType type, bool hasDefault)

Parameters

direction ParameterDirection

type DbType

hasDefault bool

Returns

DirectionalDbParamCache

Remove(IDbCommand, object?)

Drops the parameter reference from the command.

public override void Remove(IDbCommand cmd, object? currentValue)

Parameters

cmd IDbCommand

currentValue object

SaveUse(string, IDbCommand, ref object)

Binds a value and hands back the parameter reference in value, so a later Update(IDbCommand, ref object?, object?) can change it without a lookup.

public override bool SaveUse(string paramName, IDbCommand cmd, ref object value)

Parameters

paramName string

cmd IDbCommand

value object

Returns

bool

SetDefault(string, IDbCommand)

Materializes the parameter's default state and returns the live state it created.

public override object SetDefault(string paramName, IDbCommand cmd)

Parameters

paramName string

cmd IDbCommand

Returns

object

Update(IDbCommand, ref object?, object?)

Changes an already-bound parameter's value. currentValue is the parameter reference a previous SaveUse(string, IDbCommand, ref object) handed back.

public override bool Update(IDbCommand cmd, ref object? currentValue, object? newValue)

Parameters

cmd IDbCommand

currentValue object

newValue object

Returns

bool

Use(string, DbCommand, object)

Binds a value to the command for a single execution.

public override bool Use(string paramName, DbCommand cmd, object value)

Parameters

paramName string

cmd DbCommand

value object

Returns

bool

Use(string, IDbCommand, object)

Binds a value for a single run, without keeping a reference for reuse.

public override bool Use(string paramName, IDbCommand cmd, object value)

Parameters

paramName string

cmd IDbCommand

value object

Returns

bool
