Question

I’m looking to do a simple select statement to get back all the data from a table in oracle. Due to the nature of the ongoing project, the tables are constantly being updated and changed so I don’t have any solid designs.

I’m looking for a simple statement. This is all I need it to do.

Select * from myVariable

After searching I got this to compile

create or replace procedure "GET_TABLEINFO" (o_rc OUT sys_refcursor, inTableName IN varchar2) AS       

BEGIN
      execute immediate 
          'SELECT * FROM '||inTableName
      using inTableName;
  END;

but when I try to add it to a data table:

using (OracleConnection cn = new OracleConnection(connectionString))
        {
            OracleDataAdapter da = new OracleDataAdapter();
            OracleCommand cmd = new OracleCommand();
            cmd.Connection = cn;
            cmd.InitialLONGFetchSize = 1000;
            cmd.CommandText = "GET_TABLEINFO";
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add("o_rc", OracleDbType.RefCursor, ParameterDirection.Output);
            cmd.Parameters.Add("inTable", OracleDbType.Varchar2, 60, inTableName, ParameterDirection.Input);

            da.SelectCommand = cmd;
            da.Fill(dt);

I get this

Edit:

I’m not sure how to set the cursor (first time using oracle, usually use SQLSERVER). The procedure should be simple. I pass in the table name, and I need to get the data from that table. Nothing fancy, no where clauses etc.

ORA-01006: bind variable does not exist ORA-06512: at
“ODS_DEV.GET_TABLEINFO”, line 4 ORA-06512: at line 1

CREATE OR REPLACE PROCEDURE GET_TABLEINFO(o_rc OUT sys_refcursor, inTableName IN varchar2) AS       
    sqlquery VARCHAR2(32000);
BEGIN
    sqlquery := 'SELECT * FROM ' || inTableName;
    OPEN o_rc FOR sqlquery;
END;
