Class DbPreparedQueryCommand<TResult>

Namespace

NextORM.Core

Assembly

nextorm.core.dll

Prepared query command backed by an ADO.NET IDataRecord reader.

Immutable preparation data (mapper, reader behavior, SQL text, parameter flags, refresh recipe and the planned batch) lives on this object. Everything that depends on the connection an execution runs on lives in a NextORM.Core.CommandState held by a weak table keyed on that connection, so one prepared command can be executed concurrently through contexts on distinct connections while each connection keeps its own command, parameter positions and execution lease. Nothing here holds a connection, a transaction, a context or a reader.

Fields

Behavior

The CommandBehavior requested from the underlying reader. A buffered command uses SingleRow or 0; a streaming LOB command additionally sets SequentialAccess.

public readonly CommandBehavior Behavior

Field Value

CommandBehavior

NeedsParamRefresh

Whether parameter values must be refreshed before each execution rather than assuming the values baked into the plan are still current.

public readonly bool NeedsParamRefresh

Field Value

bool

NoParams

Whether the command has no parameters, allowing parameter binding to be skipped.

public readonly bool NoParams

Field Value

bool

SqlStmt

The SQL text the command was prepared with, when known.

public readonly string? SqlStmt

Field Value

string
