我的tableadapter正在将datetime2字段生成为字符串

Question

Im using tableAdapters to insert values to a table.

Heres my table aaTest

CREATE TABLE [dbo].[aaTest](
[id] [int] IDENTITY(1,1) NOT NULL,
[INVOICEDATE] [datetime2](0) NULL,
[CHARGEDATE] [datetime2](0) NULL,
[EZPASS] [varchar](50) NULL,
[PLAZA] [varchar](10) NULL,
[PLAZA2] [varchar](10) NULL,
[PDATE] [datetime2](0) NULL,
[PTIME] [varchar](9) NULL,
[PAMOUNT] [decimal](18, 2) NULL,
[PBALANCE] [decimal](18, 2) NULL,
[ACTION] [varchar](10) NULL
) ON [PRIMARY]

in my dataset, my initial fill command is select * from aatest , and ive created an insert query

INSERT INTO [aatest] ([INVOICEDATE], [CHARGEDATE], [EZPASS], [PLAZA], [PLAZA2], [PDATE], [PTIME], [PAMOUNT], [PBALANCE], [ACTION])
VALUES (@INVOICEDATE, @CHARGEDATE, @EZPASS, @PLAZA, @PLAZA2, @PDATE, @PTIME, @PAMOUNT, @PBALANCE, @ACTION)

now under my dataset designer, my query is being declared as such

public virtual int InsertQuery(string INVOICEDATE, string CHARGEDATE, string EZPASS, string PLAZA, string PLAZA2, string PDATE, string PTIME, global::System.Nullable<decimal> PAMOUNT, global::System.Nullable<decimal> PBALANCE, string ACTION) 

the problem im having is, INVOICEDATE , CHARGEDATE and PDATE are being generated as strings when they are in fact datetime2 . this causes the exception

The best overloaded method match for (mydataset) has some invalid arguments.

changing it to datetime worked temporary, but after a while they regenerated back to strings.

您需要将[datetime2]更改为[datetime] ，这应该可以解决您的问题。
