从SQL Server更改为Oracle数据库

Question

I've been asked to migrate my application from using a SQL Server database to an Oracle database.

I'm getting this error:

ORA-00942: table or view does not exist

I could be wrong, but I believe this is an issue with my statement. Is there a specific format I would need to follow connected to an oracle database over a SQL Server?

I will include my query statement:

namespace project1
{
    public class dbqry
    {
        private static string qry = "";


        public static DataTable gProjectCIS(string BSA_CD)
        {
            qry = string.Format(@"SELECT *
                    FROM CIS_TRANS
                    WHERE BSA_CD like '%{0}%'", BSA_CD);

            return dbcon.GetDataTable(qry, "ProjectCISConnectionString");
        }

        public static DataTable gProjectCIS()
        {
            qry = @"SELECT *
                    FROM CIS_TRANS";

            return dbcon.GetDataTable(qry, "ProjectCISConnectionString");
        }

Thanks!

Hello you must prefix your table with schema

  qry = string.Format(@"SELECT *
         FROM YourSchemaUser.CIS_TRANS <-- Fix your schema user name
         WHERE BSA_CD like '%{0}%'", BSA_CD);

  qry = @"SELECT * FROM YourSchemaUser.CIS_TRANS"; <-- Fix your schema user name

And Fix Package on stored procedure.

You change declaration and body, compile your package in the first time before use

Oracle is picky when it comes to case sensitivity. If the table was declared with "QUOTES", you'll need to include the quotes in your query and match case. That's probably a good start.

Answer 3

Check the object names. Also check they are in the correct case.

Check that the username you are using to connect to the database have permissions over the tables/views you are trying to use. Oracle usually says that the table does not exist when you don't have the right privileges.

You should check whether the CIS_TRANS table has the appropraite public synonym, something like:

create or replace public synonym CIS_TRANS for some_user.CIS_TRANS

where some_user is the user which created the CIS_TRANS object.
