Update PostgreSQL tables with one SQL query

Question

I have these two tables which I would like to update with one SQL query using Java code:

CREATE TABLE ACCOUNT(
 ID INTEGER NOT NULL,
 USER_NAME TEXT NOT NULL,
 PASSWD TEXT,
 FIRST_NAME TEXT,
 LAST_NAME TEXT,
 E_MAIL TEXT NOT NULL,
 COUNTRY TEXT,
 STATE TEXT,
 LAST_PASSWD_RESET DATE,
 DESCRIPTION TEXT,
 LAST_UPDATED DATE,
 CREATED DATE
)
;

-- ADD KEYS FOR TABLE ACCOUNT

ALTER TABLE ACCOUNT ADD CONSTRAINT KEY1 PRIMARY KEY (ID)
;

ALTER TABLE ACCOUNT ADD CONSTRAINT USER_NAME UNIQUE (USER_NAME)
;

ALTER TABLE ACCOUNT ADD CONSTRAINT E_MAIL UNIQUE (E_MAIL)
;

-- TABLE ACCOUNT_ROLE

CREATE TABLE ACCOUNT_ROLE(
 ID INTEGER NOT NULL,
 USER_NAME TEXT NOT NULL,
 ROLE INTEGER,
 PERMISSION TEXT,
 LAST_UPDATED DATE,
 CREATED DATE
)
;

-- CREATE INDEXES FOR TABLE ACCOUNT_ROLE

CREATE INDEX IX_RELATIONSHIP19 ON ACCOUNT_ROLE (ID)
;

-- ADD KEYS FOR TABLE ACCOUNT_ROLE

ALTER TABLE ACCOUNT_ROLE ADD CONSTRAINT KEY26 PRIMARY KEY (ID)
;

ALTER TABLE ACCOUNT_ROLE ADD CONSTRAINT RELATIONSHIP19 FOREIGN KEY (ID) REFERENCES ACCOUNT (ID) ON DELETE CASCADE ON UPDATE CASCADE
;

I use this SQL query to update first table data. For the second table I use similar SQL query:

UPDATE ACCOUNT SET ID = ?, USER_NAME = ?, PASSWD = ?, FIRST_NAME = ?, LAST_NAME = ?, E_MAIL = ?, COUNTRY = ?, STATE = ?, " CITY = ?, ADDRESS = ?, STATUS = ?, SECURITY_QUESTION = ?, SECURITY_ANSWER = ?, DESCRIPTION = ?, LAST_UPDATED = CURRENT_DATE WHERE ID = ?

How this can solve this?

Answer 1

In Postgres, you can update two tables by using CTEs:

with t1 as (
      update . . .
      returning *
     )
update t2
    . . .

It is unclear how this fits into what you are trying to do. But it is possible to write one statement in Postgres that does two updates.
