StoredProcedure does not return records












0















I am using my first StoreProcedure in mySQL as follows :



    CREATE DEFINER=`pubuducg`@`%` PROCEDURE `IsUserExists`(IN LoginEmail varchar(100))
BEGIN
SELECT LOGIN_USER_ID AS USERS FROM login WHERE LOGIN_EMAIL = @LoginEmail;
END


I am calling the procedure in C# ASP.net as follows :



                if (oMySQLConnecion.State == System.Data.ConnectionState.Open)
{
MySqlCommand oCommand = new MySqlCommand("IsUserExists", oMySQLConnecion);
oCommand.CommandType = System.Data.CommandType.StoredProcedure;
oCommand.Parameters.AddWithValue("@LoginEmail", UserEmail.EmailAddress);
var sqlResult = oCommand.ExecuteReader();
userExists = (sqlResult.HasRows ? true : false);
oMySQLConnecion.Close();
}


If I execute SQLCommmand :



SELECT LOGIN_USER_ID AS USERS FROM login WHERE LOGIN_EMAIL = @LoginEmail;


works fine.



My table collation is set to "utf8 - default collation".
Field (LOGIN_USER_ID) collation set to 'Table default'.



I called StoreProcedure in mySQL Workbench as follows :



CALL IsUserExists('abcdefg@gmail.com');


Always no records exists in oCommand.ExecuteReader() object.



Any help is appreciated.

          I found the issue. IT is related to '@' sign in stored procedure.
          Right way to use it :



                  CREATE DEFINER=`pubuducg`@`%` PROCEDURE `IsUserExists`(IN LoginEmail varchar(100))
          BEGIN
          SELECT LOGIN_USER_ID AS USERS FROM login WHERE LOGIN_EMAIL = LoginEmail;
          END


          No need to put '@' sign inside sql query.
