生成通用的 INSERT/UPDATE 触发器以符合数据？

我正在尝试在多个表上生成触发器以强制数据为大写并在插入或更新数据时修剪前导和尾随空格。我遇到的问题是在触发器中确定一种将 INSERTED 伪表绑定到基表的通用方法。并非所有表都具有相同的 PK 名称，尽管许多表在每个表中都有一个可以使用的名为 _DataChanges_RowID 的唯一列。我知道我可以检查 PK 并使用这些列生成触发器，但在查看之前，我想知道是否有一种通用方法可以将 INSERTED 伪表连接到基表，这种方法更简单且与列无关。

DECLARE @TriggerTemplate AS VARCHAR(MAX) = 
'CREATE TRIGGER <<SchemaName>>.<<TriggerName>> ON <<FullTableName>>
AFTER INSERT, UPDATE
AS BEGIN
    IF (ROWCOUNT_BIG() = 0)
        RETURN;
    IF TRIGGER_NESTLEVEL(( SELECT object_id FROM sys.triggers WHERE QUOTENAME(name) = ''<<TriggerName>>'' ), ''AFTER'', ''DML'') < 1
    UPDATE <<FullTableName>>
    SET <<SQLColumnUpdate>>
    WHERE <<FullTableName>>._DataChanges_RowID IN (SELECT _DataChanges_RowID FROM INSERTED);
END;
GO
sp_settriggerorder <<SchemaName>>.<<TriggerName>>, ''FIRST'', ''INSERT'';
sp_settriggerorder <<SchemaName>>.<<TriggerName>>, ''FIRST'', ''UPDATE'';
GO
';
