Problems with varchar2 column and a select statement

Question

Hi to all,
I am new to ODP...so I would really appreciate your help..
I am having problems with using the following code:
con.ConnectionString = "User Id=bla;Password=bla;Data Source=bla;";
string cmdQuery = "SELECT * from try where data ="+textBox1.Text+"";
OracleCommand cmd = new OracleCommand(cmdQuery);
cmd.Connection = con;
cmd.CommandType = CommandType.Text;
OracleDataReader reader = cmd.ExecuteReader();
while (reader.Read())
MessageBox.Show(reader.GetString(0)+"");
cmd.Dispose();
con.Close();
where:
data is the name of a field in the table
textBox1 is the name of a text box where the user inserts the values..
The error that appears is "Invalid identifier"..
I hope it makes sense...and please help...

Hi,
I'm fairly sure it IS the single quotes actually. Print out the string you're trying to excute, then try it outside odp.net, does it work?
For example:
SQL> select * from dual where dummy=foo;
select * from dual where dummy=foo
ERROR at line 1:
ORA-00904: "FOO": invalid identifier
SQL> select * from dual where dummy='foo';
no rows selected
Cheers,
Greg
