How can I pass an array variable to a SQL Server stored procedure using C# and insert array values into a whole row?
Thanks in advance.
SQL Server table:
ID | Product | Description
-------------------------------
8A3H | Soda | 600ml bottle
C# array:
string[] info = new string[] {"7J9P", "Soda", "2000ml bottle"};
SQL Server stored procedure:
ALTER PROC INSERT
(@INFO_ARRAY ARRAY)
AS
BEGIN
INSERT INTO Products VALUES (@INFO_ARRAY)
END
In SQL Server 2008 and later
Create a type in SQL Server like so:
CREATE TYPE dbo.ProductArray
AS TABLE
(
ID INT,
Product NVARCHAR(50),
Description NVARCHAR(255)
);
Alter your procedure in SQL Server:
ALTER PROC INSERT_SP
@INFO_ARRAY AS dbo.ProductArray READONLY
AS
BEGIN
INSERT INTO Products SELECT * FROM @INFO_ARRAY
END
Then you'll need to create a DataTable object with values to pass in C#:
DataTable dt = new DataTable();
//Add Columns
dt.Columns.Add("ID");
dt.Columns.Add("Product");
dt.Columns.Add("Description");
//Add rows
dt.Rows.Add("7J9P", "Soda", "2000ml bottle");
using (conn)
{
SqlCommand cmd = new SqlCommand("dbo.INSERT_SP", conn);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter dtparam = cmd.Parameters.AddWithValue("@INFO_ARRAY", dt);
dtparam.SqlDbType = SqlDbType.Structured;
}
dtparam.SqlDbType = SqlDbType.Structured;here is a way simpler example:
I've been searching through all the examples and answers of how to pass any array to sql server,till i found this linK, below is how I applied it to my project:
--The following code is going to get an Array as Parameter and insert the values of that --array into another table
Create Procedure Proc1
@INFO_ARRAY ARRAY nvarchar(max) //this is the array your going to pass from C# code
AS
declare @xml xml
set @xml = N'<root><r>' + replace(@INFO_ARRAY,',','</r><r>') + '</r></root>'
Insert into Products
select
t.value('.','varchar(max)')
from @xml.nodes('//root/r') as a(t)
END
Hope you enjoy it
