GetQueryParameterNormalizer()

Returns instance of IQueryParametersNormalizer, which implements normalization logic for parameters of single query. E.g. it could include:

• trimming names that are too long
• removing/replacing unsupported characters
• name deduplication for parameters with same name

. For implementation without state it is recommended to return static instance. E.g. this could be done for providers with positional parameters that ignore names.

public override IQueryParametersNormalizer GetQueryParameterNormalizer()

Returns

IQueryParametersNormalizer

GetSchemaProvider()

public override ISchemaProvider GetSchemaProvider()

Returns

ISchemaProvider

GetSqlOptimizer(DataOptions)

public override ISqlOptimizer GetSqlOptimizer(DataOptions dataOptions)

Parameters

dataOptions DataOptions

Returns

ISqlOptimizer

IsDBNullAllowed(DataOptions, DbDataReader, int)

public override bool? IsDBNullAllowed(DataOptions options, DbDataReader reader, int idx)

Parameters

options DataOptions

reader DbDataReader

idx int

Returns

bool?

SetParameter(DataConnection, DbParameter, string, DbDataType, object?)

public override void SetParameter(DataConnection dataConnection, DbParameter parameter, string name, DbDataType dataType, object? value)

Parameters

dataConnection DataConnection

parameter DbParameter

name string

dataType DbDataType

value object
