Re: JDBC behaviour - Mailing list pgsql-jdbc

let me put this way

 

table employee ( id PrimaryKey, name )

 

In Java ( just little pseudo-code way )

 

try {

conn.setAutoCommit(false);

     try { executeUpdate("insert into employee(id,name) values(1, 'K1')"); } catch ...

     try { executeUpdate("insert into employee(id,name) values(1, 'K1')"); } catch ...

     try { executeUpdate("insert into employee(id,name) values(1, 'K2')"); } catch ...

conn.commit();

} catch ...

 

throws error 

1. duplicate key value violates unique constraint "employee_pkey"

2. current transaction is aborted, commands ignored until end of transaction block

 

 

In PL/SQL ( similar error thrown when used BEGIN-END )

 

postgres=# begin;

BEGIN

postgres=# insert into employee values (1,'aa');

INSERT 0 1

postgres=# insert into employee values (2,'bb');

INSERT 0 1

postgres=# insert into employee values (3,'cc');

INSERT 0 1

postgres=# insert into employee values (1,'aa');

ERROR:  duplicate key value violates unique constraint "employee_pkey"

DETAIL:  Key (eid)=(1) already exists.

postgres=# insert into employee values (4,'dd');

ERROR:  current transaction is aborted, commands ignored until end of transaction block

 

 

my question Java setAutoCommit (false) is behaving like PL/SQL BEGIN-END
