为什么此 SQL Server UPDATE 语句会引发日期时间转换错误？

Question

我在尝试弄清楚如何使此更新正常工作时遇到了一些麻烦。

我认为我以前做过没有问题，但现在似乎不起作用。我不知道会发生什么变化。

当我执行此操作以及包含这些字段的任何类似更新语句时：

UPDATE Clientes 
SET CodigoComisionista = 450 
WHERE CodigoEmpresa = 1 
  AND CodigoCliente = '430002801';

我得到一个 varchar 到日期时间的转换错误：

SQL 错误 (3621): La conversión del tipo de datos varchar en datetime produjo un valor fuera de interval
Se terminó la instrucción.
受影响的行：0 找到的行：0 警告：0 1 个查询中 0 个的持续时间：0,000 秒。

查看那里的列类型，我看不出为什么会引发 datetime 转换。有什么想法吗？

select COLUMN_NAME, DATA_TYPE 
from INFORMATION_SCHEMA.COLUMNS IC 
where TABLE_NAME = 'Clientes' and 
(
COLUMN_NAME = 'CodigoEmpresa'
OR COLUMN_NAME = 'CodigoCliente'
OR COLUMN_NAME = 'CodigoComisionista'
)

=====>

"COLUMN_NAME"           "DATA_TYPE"
"CodigoEmpresa"         "smallint"
"CodigoCliente"         "varchar"
"CodigoComisionista"    "int"

谢谢！

这是与“Clientes”表关联的触发器：

也许 UPDATE 会创建一个重复的行。
