Execute multiple queries in single Oracle command in C#

Question

I am using visual studio 2013 and oracle database.I want execute multiple create table queries at once in single oraclecommand is it possible ? I am trying following but not working

OracleCommand cmd = new OracleCommand();
cmd.Connection = con;
cmd.CommandText = "create table test(name varchar2(50) not null)"+"create table test2(name varchar2(50) not null)"; 
//+ "create table test3(name varchar2(50) not null)"+"create table test3(name varchar2(50) not null)";
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();

Got error at cmd.ExecuteNonQuery();

Solution

In order to execute more than one command put them in begin ... end; block. And for DDL statements (like create table) run them with execute immediate. This code worked for me:

OracleConnection con = new OracleConnection(connectionString);
con.Open();

OracleCommand cmd = new OracleCommand();
cmd.Connection = con;
cmd.CommandText =
    "begin " +
    "  execute immediate 'create table test1(name varchar2(50) not null)';" +
    "  execute immediate 'create table test2(name varchar2(50) not null)';" +
    "end;";
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
con.Close();
