创建具有参数的程序

创建具有参数的程序

这是我的代码:

using (MySql.Data.MySqlClient.MySqlConnection cn = new
MySql.Data.MySqlClient.MySqlConnection(
            Properties.Settings.Default.CONNNConnectionString))
        {
            cn.Open();
            MySql.Data.MySqlClient.MySqlCommand cm = new
            MySql.Data.MySqlClient.MySqlCommand();
            cm.CommandType = CommandType.Text;
            cm.Connection = cn;
            cm.CommandText="CREATE  PROCEDURE `GetMovement`(RefArtt vARCHAR(20),idos INTEGER) "+
"BEGIN "+
"SET @Qt=0; "SELECT * ,@Qt:=@Qt+qteliv-qtesor as stock FROM tableInOut;"+
"End";
cm.ExecuteNonQuery();}


异常:您的SQL语法有错误;检查与您的MySQL服务器版本相对应的手册,以在``@ Qt'= 0''附近使用正确的语法;选择 * ...

最佳答案

我不明白您的查询100%:

SELECT * ,@Qt:=@Qt+qteliv-qtesor as stock FROM tableInOut;


如果可以解释,以便我在需要时调整代码,但是这里有一个示例:

using (MySql.Data.MySqlClient.MySqlConnection cn = new
MySql.Data.MySqlClient.MySqlConnection(
            Properties.Settings.Default.CONNNConnectionString))
{
    cn.Open();
    MySql.Data.MySqlClient.MySqlCommand cm = new
    MySql.Data.MySqlClient.MySqlCommand();
    cm.CommandType = CommandType.Text;
    cm.Connection = cn;
    cm.CommandText=@"
    DELIMITER //
     CREATE PROCEDURE GetMovement(IN RefArtt VARCHAR(20), IN idos INTEGER)
       BEGIN
        SELECT *
        FROM tableInOut
        WHERE ref = RefArtt AND id = idos;
       END //
    DELIMITER ;
    ";
    cm.ExecuteNonQuery();
}
