[Postgres] Constraint added automatically NOT DEFERRABLE INITIALLY IMMEDIATE
By default is NOT DEFERRABLE and if it is NOT DEFERRABLE it is also IMMEDIATE, right?
Should I use those even it is set by default? Or it does imply something other?
Because the SQL generates with this Keyword in anyplace. and I'm not sure about the implications of all.
SQLite Autoincrement
Hello, I have exported the SQL for a SQLite Database. In the tables, I have PRIMARY_KEY and AUTOINCREMENT.
CREATE TABLE CSS_AT_RULES (
id integer NOT NULL AUTOINCREMENT,
css_version varchar(10) NOT NULL,
syntax_id integer NOT NULL,
CONSTRAINT CSS_AT_RULES_pk PRIMARY KEY (id)
);
Using this format, SQLite is throwing an error due the AUTOINCREMENT is not declared as PRIMARY KEY yet (it is being done in the CONSTRAINT). I am using the java sqlite-jdbc-3.8.11.2.jar driver from org.xerial
SQL Error [1]: [SQLITE_ERROR] SQL error or missing database (near "AUTOINCREMENT": syntax error) java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "AUTOINCREMENT": syntax error)
A possible correct syntax (regarding to the SQLite documentation https://www.sqlite.org/autoinc.html ) for the previous example would be:
CREATE TABLE CSS_AT_RULES (
id integer NOT NULL PRIMARY KEY AUTOINCREMENT,
css_version varchar(10) NOT NULL,
syntax_id integer NOT NULL
);Could you please confirm if I am right?
Regards,
Javier.
Hello,
Yes, it is a bug.
I think, the correct syntax is (as sqlite's faq mentions https://www.sqlite.org/faq.html#q1):
CREATE TABLE CSS_AT_RULES (
id integer NOT NULL,
css_version varchar(10) NOT NULL,
syntax_id integer NOT NULL,
CONSTRAINT CSS_AT_RULES_pk PRIMARY KEY (id)
);
If column has type 'integer' and 'primary key' then has also 'autoincrement'.
In this case, the fastes solution is to unset an autoincrement option.
I hope this helps.

Need for in-house version
Hi guys,
Do you plan to develop desktop version of Vertabelo modeling tool, since there is no modern analogs of Erwin which is almost obsolete?
FK tag in "properties" column of auto-generated documentation
Is it possible to add the "FK" in the "properties" column of the fields that are foreign keys in some table, just like it says "PK" for the primary key?
Add data type support for PostgreSQL
This is the datatype recommended by PG to use but it isn't supported.
Likewise Serial2 would be a nice addition
