public PositionalDbParamInfo()

Methods

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

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
