AppendUpdateCommand(StringBuilder, String, String, IReadOnlyList<ColumnModification>, IReadOnlyList<ColumnModification>)
附加 SQL 命令,以將資料列更新至所建置的命令。
protected virtual void AppendUpdateCommand (System.Text.StringBuilder commandStringBuilder, string name, string schema, System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Update.ColumnModification> writeOperations, System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Update.ColumnModification> conditionOperations);
abstract member AppendUpdateCommand : System.Text.StringBuilder * string * string * System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Update.ColumnModification> * System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Update.ColumnModification> -> unit
override this.AppendUpdateCommand : System.Text.StringBuilder * string * string * System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Update.ColumnModification> * System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Update.ColumnModification> -> unit
Protected Overridable Sub AppendUpdateCommand (commandStringBuilder As StringBuilder, name As String, schema As String, writeOperations As IReadOnlyList(Of ColumnModification), conditionOperations As IReadOnlyList(Of ColumnModification))
