我得到的错误是

无法将值 NULL 插入列“dealrid”、表“DB_LMS.dbo.LMS_dealerorusercreation”；列不允许空值。插入失败。

Answer 1

你需要做两件事之一，要么......

• 确保您为该列传递一个非空值，或者；
• 如果这是字段的所需属性，请确保您的列接受空值。

Answer 2

如错误消息所述，它是juat。

您正在尝试对已创建不为 null 的 dealrid 的表执行插入操作。如果您查看您的插入语句，您并没有选择并将值传递给它。

Answer 3

我在代码中看到的错误。

在插入表 LMS_dealerorusercreation 时，您从未选择 dealrid 列。请选择相同的。

INSERT INTO LMS_dealerorusercreation(
rid,
stateid,
regonid,
Locid,
addres,
dealrname,
landno,
mobno,
altcontno,
email,
desig,
reporting,
status,
CompanyId,
dealrid
)
VALUES(
@rid,
@stateid,
@regonid,
@Locid,
@address,
@dealrname,
@landno,
@mobno,
@altcontno,
@email,
@desig,
@reporting,
@status,
@CompanyId,
@dealrid
)
