I have a SQL Server table with 10 columns:
CREATE TABLE [bank].[CommonPostingsFromBankFiles]
(
[Id] [INT] IDENTITY(1,1) NOT NULL,
[BankRegistrationNumber] [INT] NOT NULL,
[BankAccountNumber] [BIGINT] NOT NULL,
[BankName] [NVARCHAR](50) NULL,
[BankAccount] [NVARCHAR](50) NULL,
[PostingAmount] [DECIMAL](18, 2) NOT NULL,
[PostingDate] [DATE] NOT NULL,
[Primo] [CHAR](1) NULL,
[PostingText] [NVARCHAR](100) NULL,
[HideThisRecord] [BIT] NULL,
CONSTRAINT [PK_CommonPostingsFromBankFiles]
PRIMARY KEY CLUSTERED ([BankRegistrationNumber] ASC,
[BankAccountNumber] ASC,
[PostingAmount] ASC,
[PostingDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
)
and a stored procedure that takes 7 parameters:
ALTER PROCEDURE [bank].[spInsertCommonPostings]
(@BankRegistrationNumber INT,
@BankAccountNumber BIGINT,
@BankName NVARCHAR(50),
@PostingAmount DECIMAL(18, 2),
@PostingDate DATE,
@Primo CHAR(1),
@PostingText NVARCHAR(100))
AS
BEGIN
IF NOT EXISTS (SELECT *
FROM bank.CommonPostingsFromBankFiles
WHERE BankRegistrationNumber = @BankRegistrationNumber
AND BankAccountNumber = @BankAccountNumber
AND BankName = @BankName
AND PostingAmount = @PostingAmount
AND PostingDate = @PostingDate)
INSERT INTO bank.CommonPostingsFromBankFiles (BankRegistrationNumber, BankAccountNumber,
BankName, PostingAmount,
PostingDate, Primo, PostingText)
VALUES (@BankRegistrationNumber, @BankAccountNumber,
@BankName, @PostingAmount,
@PostingDate, @Primo, @PostingText);
END;
What I want is to use Dapper to write a List<Postings>
to the table using the stored procedure.
I have searched and searched but found no example that helped me.
If I do a
connection.Execute(sql: "spMyStoredProc", MyList, commandType: CommandType.StoredProcedure);
I get an error
Procedure or function spMyStoredProc has too many arguments specified
If I replace the name of the stored procedure with the SQL from the stored procedure and set CommandType
to Text it works as expected.
Could anybody please post me an example showing how to insert my list using my stored procedure.

Simplistically, and assuming the names of the properties in your C# object are identical to the names of the parameters in your stored proc, you could:
If the param/props aren't aligned it may be simplest to provide an anonymous type populated with values from x that covers them
For a list of 10 objects it will invoke the proc 10 times; it's not the fastest way to do it, but I don't think you've stated any particular goals re performance etc.
