使用C＃连接到Oracle数据库

Question

I want to test Oracle Database in my C# windows application. I have created a workspace on Oracle Application Express. I have also created DNS and the connection is formed successfully.

On successful connection I have written a code to get the list of tables.

schemaTable = connection.GetSchema("Tables");

This code snippet successfully returns the list the tables. Now when I try to read the data from EMP table I receive below error:

ERROR [42S02] [Oracle][ODBC][Ora]ORA-00903: invalid table name

Query to retrieve the data from EMP table

queryString: "Select * from [EMP];"

 using (OdbcConnection connection = new OdbcConnection(connString))
        {
            try
            {
                connection.Open();
                OdbcDataAdapter da = new OdbcDataAdapter(queryString, connection);
                da.Fill(fillGridDt);

Answer 1

I figured out the solution. It was throwing the error invalid table name as i was using [] brackets with table name. ie Select * from [EMP] I tried the query with Select * from EMP; and now it works
