Using transaction commands directly instead of PgSqlTransact

Post by JORGEMAL » Tue 31 Jan 2012 16:05

Talking about transactions, is it possible to issue BEGIN, COMMIT, ROLLBACK commands instead of using PgSqlTransaction?

If so, what would be the advantage/disadvantage of issuing transaction command directly?

Yes, you can. You can use PgSqlScript, which allows you to execute several SQL statements one by one, for this. For more information please refer to: ... cript.html
For example you can use the following code:

Code: Select all

PgSqlConnection conn = new PgSqlConnection("Host=***;port=***;user id=***;password=***;");
            PgSqlScript script = new PgSqlScript();
            script.Connection = conn;
            script.ScriptText = @"begin;
select * from dept where deptno=212;
update dept set loc='NY' where deptno=212;
select * from dept where deptno=212;
DDL/DML Scripts:

Code: Select all

  deptno integer NOT NULL,
  dname character varying(14),
  loc character varying(13),
  CONSTRAINT dept_pkey PRIMARY KEY (deptno)

INSERT INTO dept(deptno, dname, loc)
    VALUES (212, 'Butcher', 'Vegas');
