I am struggling while creating new database tables with foreign keys in Informix DB.
I need to migrate from one database to another. I am using DBeaver as DB browsing and editing tool. I am trying to run script like this (I just changed names). The commands come from DBeaver DDL export itself, so this is how it should be.
DROP TABLE IF EXISTS eapp:test_table1;
CREATE TABLE eapp:test_table1 (
column1 smallint NOT NULL,
PRIMARY KEY (column1) CONSTRAINT table1_pk
);
DROP TABLE IF EXISTS eapp:test_table2;
CREATE TABLE eapp:test_table2 (
column1 smallint NOT NULL,
column2 varchar(100) NOT NULL,
column3 smallint NOT NULL,
column4 smallint,
PRIMARY KEY (column1) CONSTRAINT table2_pk,
FOREIGN KEY (column4) REFERENCES eapp:test_table1(column1) ON DELETE RESTRICT ON UPDATE RESTRICT CONSTRAINT table2_fk
);
However, execution keeps crashing with a weird trimmed error message:
The language is Czech and it says something like "Syntax error. (Important notice: Database servers, that". But the rest is trimmed even in detail, so I have no idea what is going on.

I was unable to Google message like that, so I am trying to ask here, if anyone has some experience with Informix DB and could possibly give me some hints.
I already tried to remove FK declaration from table creation and add it afterwards via ALTER TABLE, but it yields the same...
DBeaver is not generating valid Informix DDL. Informix does not understand ON DELETE RESTRICT ON UPDATE RESTRICT syntax.
From the online manual:
REFERENCES Clause
|--REFERENCES--table--+------------------+---------------------->
| .-,------. |
| V | |
'-(----column-+--)-'
>--+-------------------------+----------------------------------|
| (1) |
'-------ON DELETE CASCADE-'
In documentation of postgreSQL 9.6, it said to have serial equivalent we have to link the sequence to the field.
https://www.postgresql.org/docs/9.6/datatype-numeric.html (¤ 8.1.4)
I exactly applied the same code :
CREATE SEQUENCE seq_import_trame INCREMENT 1 START 1;
CREATE TABLE import_trame (
id integer NOT NULL DEFAULT nextval('seq_import_trame'),
...,
CONSTRAINT pk_import_trame PRIMARY KEY (id)
);
ALTER SEQUENCE seq_import_trame OWNED BY import_trame.id;
But I have an error while executing script with pgAdmin.
Relation "seq_import_trame" already exist".
Code: 42P07
Line 8: ALTER SEQUENCE.....
It's very strange because 42P07 error is duplicate_table.
And if we don't make the link, the sequence is not dropped when we drop the table.
Any idea ?
I see no problem on DB Fiddle:
Schema (PostgreSQL v9.6)
CREATE SEQUENCE seq_import_trame INCREMENT 1 START 1;
CREATE TABLE import_trame (
id integer NOT NULL DEFAULT nextval('seq_import_trame'),
CONSTRAINT pk_import_trame PRIMARY KEY (id)
);
ALTER SEQUENCE seq_import_trame OWNED BY import_trame.id;
View on DB Fiddle
Check again your script.
I always get the error on postgres sql can anyone help me
ERROR: Syntaxerror in „(“ LINE 4: Liga_Nr int(1),
^
********** ERROR **********
ERROR: Syntaxerror in „(“ SQL Status:42601 Symbol:79
Here is my code
DROP TABLE IF EXISTS Liga;
Create Table Liga(
Verband varchar(90),
Liga_Nr int(1),
PRIMARY KEY(Liga_Nr)
);
DROP TABLE IF EXISTS Spiel;
CREATE Table Spiel(
);
DROP TABLE IF EXISTS Verein;
CREATE Table Verein(
);
DROP TABLE IF EXISTS Spieler;
CREATE Table Spieler(
PRIMARY KEY(Spieler_ID)
);
Integer types don't accept a parameter. The correct code is:
Create Table Liga(
Verband varchar(90),
Liga_Nr int,
PRIMARY KEY(Liga_Nr)
);
If you want to store a small number, use smallint. You can read about numeric types here.
I am trying to alter the size of a column 'Login' which is a primary key in my table 'Utilisateurs' which is in my in 'ME' database. I tried this command:
ALTER TABLE ME.UTILISATEURS
ALTER COLUMN login VARCHAR (50) ;
but I get this error:
Error code -1, SQL state 42X01: syntax Erreur : Encountered "varchar" at line 2, column 21.
I am using netbeans IDE, the Derby Driver.
ALTER TABLE ME.UTILISATEURS
ALTER COLUMN login SET DATA TYPE VARCHAR(50)
I am getting strange errors while trying to create a simple database using isql tools from the Firebird package.
The same code for creating a table works for other tables with other names.
I've tried with and without quotes surrounding fields and table names, no success.

I don't get why it's impossible to create the first table "RULES" although the commands are similar to other tables.
Even without all the triggers and foreign keys (alter table..) I am getting at leaast the last error.
it says "Unknown columns in index FK_LINK_FRL_FS" but no mention of other similar indexing tables.
I am just starting working with databases and it could be that I missed or mixed something,
but I tried to compile with too many changes and still getting errors.
I've found more or less similar code here
http://sergworks.wordpress.com/category/firebird/
and I was able to compile it without problems.
Could somebody point me in the right direction or show how it is done in another way?
You have an unnessesary comma in the end of the PK constraint:
CONSTRAINT PK_RULE_ID
PRIMARY KEY (RULE_ID),
So the parser expexts definition of field or constraint but it finds ")". Delete the comma and you should be OK.
