Execute multiple queries in single Oracle command in C#
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();
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();
