问题描述
我如何使用C#和插入阵列值成一整排传递一个数组变量到SQL Server存储过程?
提前感谢。
SQL Server表:
ID |产品|说明
-------------------------------
8A3H |纯碱| 600毫升瓶
C#数组:
的String []信息=新的String [] {7J9P,苏打,2000毫升瓶};
SQL Server存储过程:
ALTER PROC INSERT
(@INFO_ARRAY ARRAY)
AS
BEGIN
INSERT INTO产品VALUES(@INFO_ARRAY)
端
解决方案
在SQL Server 2008及更高版本
创建像这样在SQL Server类型:
CREATE TYPE DBO .ProductArray
如表
(
ID INT,
的产物NVARCHAR(50),
说明NVARCHAR(255)$ b $二);
ALTER在SQL Server的过程:
ALTER PROC INSERT_SP
@INFO_ARRAY AS dbo.ProductArray READONLY
AS
BEGIN
INSERT INTO产品SELECT * FROM @INFO_ARRAY
END
然后你需要创建一个数据表
与值对象在C#中传递:
DataTable的DT =新的DataTable();
//添加列
dt.Columns.Add(ID);
dt.Columns.Add(产品);
dt.Columns.Add(描述);
//添加行
dt.Rows.Add(7J9P,苏打,2000毫升瓶);使用
(康涅狄格州)
{
的SqlCommand CMD =新的SqlCommand(dbo.INSERT_SP,康恩);
cmd.CommandType = CommandType.StoredProcedure;
的SqlParameter dtparam = cmd.Parameters.AddWithValue(@ INFO_ARRAY,DT);
dtparam.SqlDbType = SqlDbType.Structured;
}
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
解决方案
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;
}
