I am trying to write a script that creates a table, adds some constraints and then make a column auto-increment. As far as I read it happens with generator and before insert trigger.
Here is my code:
CREATE TABLE BLANKS
(
ID INT NOT NULL PRIMARY KEY,
BLANK_ID INT NOT NULL,
DATABASE_ID SMALLINT NOT NULL,
BLANK_VERSION DECIMAL,
CONSTRAINT ROW_UNIQUENESS UNIQUE(BLANK_ID, DATABASE_ID, BLANK_VERSION)
)
/* Autoincrement for field (ID) */
CREATE GENERATOR GEN_BLANKS_ID;
SET TERM ^ ;
CREATE TRIGGER BLANKS_BI FOR BLANKS
ACTIVE BEFORE INSERT POSITION 0
AS
BEGIN
IF (NEW.ID IS NULL) THEN
NEW.ID = GEN_ID(GEN_BLANKS_ID,1);
END^
SET TERM ; ^
But it just doesn't work. It creates the table and the generator but when it reaches SET TERM ^ ; the script fails with error:
SQL Error: Dynamic SQL Error SQL error code = -104 Token unknown - line 1, column 5 TERM. Error Code: -104. can't format message 13:896 -- message file C:\Program Files (x86)\SQL Maestro Group\firebird.msg not found The SQL: SET TERM ^ ;
;
Do you have any suggestions?
Add a semicolon after the create table statement and remove the set term ^ syntax if your SQL client doesn't like it:
CREATE TABLE BLANKS
(
ID INT NOT NULL PRIMARY KEY,
BLANK_ID INT NOT NULL,
DATABASE_ID SMALLINT NOT NULL,
BLANK_VERSION DECIMAL,
CONSTRAINT ROW_UNIQUENESS UNIQUE(BLANK_ID, DATABASE_ID, BLANK_VERSION)
);
/* Autoincrement for field (ID) */
CREATE GENERATOR GEN_BLANKS_ID;
CREATE TRIGGER BLANKS_BI FOR BLANKS
ACTIVE BEFORE INSERT POSITION 0
AS
BEGIN
IF (NEW.ID IS NULL) THEN
NEW.ID = GEN_ID(GEN_BLANKS_ID,1);
END

how to create function in PostgreSQL am using below code

CREATE TABLE sample3 (ID INT NOT NULL CONSTRAINT CHK_ID CHECK (dbo.CheckFunction(ID) = 1))
and getting below error
ERROR: syntax error at or near "BEGIN"
LINE 8: BEGIN

********** Error **********
ERROR: syntax error at or near "BEGIN"
SQL state: 42601
Character: 132
please help to solve the issue
As documented in the manual an IF requires a THEN. Additionally, parameters cannot be prefixed with a #. To avoid a name clash between a parameter name and a column name you should use a different name for the parameter. A common approach is to prefix parameters with p_
However your function is needlessly complex and can be simplified substantially if you return a proper boolean rather than a bit:
Create FUNCTION check_function (p_ID INT)
RETURNS boolean AS
$$
select exists (SELECT 1 FROM sampleall WHERE id = p_id);
$$
LANGUAGE sql;
Your check constraint can then be simplified to:
CREATE TABLE sample3 (ID INT NOT NULL CONSTRAINT CHK_ID CHECK (check_Function(ID));
Using: Application Express 18.1.0.00.45
Please note: I am very new to Oracle Apex and SQL.
For a project I have to create an Application straight in Apex.
I was trying to create a table that works with a Primary Key that auto-increments itself.
Yesterday I created my first Application with a page for user input in a table, a page with table display and filter option and was playing around with forms, dashboard and authentication methods.
I removed the app after playing to start the "Real Work", but I my enthusiasm went quickly away when I realized that I am doing something very wrong but am not sure what.. :)
After lots of googling / reading etc, I am still not sure what is wrong..
See below the code:
-- Create Sequence
CREATE SEQUENCE seq_odm_for_pk
START WITH 1
INCREMENT BY 1
CACHE 100;
-- Create Table for User Input
CREATE TABLE ODM_Progress_v1 (
-- General Details:
ID int NOT NULL AUTO_INCREMENT,
TRAINEE varchar(50) NOT NULL, --1
COACH varchar(50) NOT NULL, --2
STATUS varchar(50) NOT NULL, --3
REGION varchar(5) NOT NULL, --4
-- Actions:
ACTION_TAKEN varchar(100) NOT NULL, --5
ACTION_DETAILS varchar(250), --6
ACTIONED_BY varchar(50) NOT NULL, --7
ACTIONED_DATE DATE NOT NULL, --8
-- Constraints that perform checks for each column:
CONSTRAINT CHK_GeneralDetails CHECK (TRAINEE!=COACH AND (STATUS IN('New', 'In Progress', 'Completed')) AND (REGION IN('EMEA', 'APAC', 'AMER'))),
-- Set Primary Key (Trainee+Coach):
CONSTRAINT PK_ODMProgress PRIMARY KEY (TRAINEE,REGION,ID)
);
-- Create Trigger
CREATE trigger_for_pk_odm_progress
BEFORE INSERT ON ODM_Progress_v1
FOR EACH ROW
WHEN (new.ID is null)
BEGIN
select seq_odm_for_pk.nextval into :new.ID from DUAL;
-- :new.PK_ODMProgress := seq_odm_for_pk.nextval;
END;
The script finishes running with 3 errors, see below:
CREATE OR REPLACE SEQUENCE seq_odm_for_pk START WITH 1
INCREMENT BY 1 CACHE 100
ORA-00922: missing or invalid option
CREATE TABLE ODM_Progress_v1 ( -- General Details: ID int NOT

CREATE OR REPLACE trigger_for_pk_odm_progress BEFORE INSERT ON

seq_odm_for_pk.nextval INTO :new.ID FROM DUAL; --
:new.PK_ODMProgress := seq_odm_for_pk.nextval; END;
ORA-00922: missing or invalid option
Can you please help me unravel this (to me, complete) mystery?
The final application should at least contain 1 table with primary key and sequence (created from scratch, see above) and have at least 2 pages, one is for data input, the other is for data display with use tabs or navigation menu.
Thank you in advance!
That code looks OK, more or less. Here you go:
SQL> CREATE SEQUENCE seq_odm_for_pk
2 START WITH 1
3 INCREMENT BY 1
4 CACHE 100;
Sequence created.
Table: I'm on 11g which doesn't support auto-incremented columns, so I removed that clause:
SQL> CREATE TABLE ODM_Progress_v1 (
2 -- General Details:
3 ID int NOT NULL AUTO_INCREMENT,
4 TRAINEE varchar(50) NOT NULL, --1
5 COACH varchar(50) NOT NULL, --2

14 CONSTRAINT CHK_GeneralDetails CHECK (TRAINEE!=COACH AND (STATUS IN('New', 'In Progress', 'Completed')) AND (REG
ION IN('EMEA', 'APAC', 'AMER'))),

17 );

So:
sequence is OK, but - for vast majority of cases - a simple create sequence seq_odm_for_pk; is enough
for CREATE TABLE remove AUTO_INCREMENT (if you aren't on 12c)
trigger: remove underscore
Now, depending on where you executed those commands, you might have got errors. If you ran them in Apex SQL Workshop, run them one-by-one (and keep only one command in the window). Doing so, it should be OK.
Also, I've noticed that you used VARCHAR datatype - switch to VARCHAR2.
Finally, there's no use in constraining primary key columns with the NOT NULL clause - primary key will enforce it by default.
As of Apex itself: the way you described it, you should create an Interactive Report; the Wizard will create a report (to view data), along with a form (to insert/modify/delete data).
The query you ran in your script is not the same as you posted in your code, as can be read in error text.
Code for creating your sequence as you wrote it in your code should be fine:
CREATE SEQUENCE seq_odm_for_pk
START WITH 1
INCREMENT BY 1
CACHE 100;
As of 11g you cannot use AUTO_INCREMENT in Oracle when creating table. It is not even necessary since you're having a trigger populating your :new.ID with nextval from sequence. So, in your CREATE TABLE remove AUTO_INCREMENT for your ID and everything should be fine.
While creating a trigger you omitted TRIGGER keyword (CREATE OR REPLACE TRIGGER trigger_for_pk_odm_progress).
Also, I'm not sure if you did or did not put END; at the end of your create trigger command. if not, put it.
I hope that helped :)
My question starts here: How to setup auto increment for Service-Based Database
So if I have to go this way to reset auto increment after deleting a table row:
http://befused.com/mysql/reset-auto-increment
first time I have deal with T-SQL extension and SQL generally. What is wrong here, not sure if I got it right:
CREATE TABLE [dbo].[Tab1] (
[Id] INT IDENTITY (1, 1) NOT NULL,
[Phrase] TEXT NOT NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
SELECT MAX( Id ) FROM [Tab1] ;
ALTER TABLE Tab1 AUTO_INCREMENT = number;
got this errors:
Severity Code Description Project File Line Suppression State Error
SQL80001: Incorrect syntax near ''. Expecting '.', ID, or QUOTED_ID.
dbo.User 8
and:
SeverityCode Description Project File Line Suppression State Error
SQL80001: Incorrect syntax near ''. dbo.User 7
MYSQL
CREATE TABLE Tab1 (
Id INT NOT NULL AUTO_INCREMENT,
Phrase TEXT NOT NULL,
PRIMARY KEY CLUSTERED (Id ASC)
);
ALTER TABLE Tab1 MODIFY COLUMN Id INT AUTO_INCREMENT // To set column as auto increment
MSSQL (In case someone needs it)
The create table syntax is OK but in creating auto increment column, you can add it like this
CREATE TABLE [dbo].[User] (
[Id] INT NOT NULL AUTO_INCREMENT PRIMARY KEY, // Set column as primary key and auto increment
[Phrase] TEXT NOT NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
SELECT MAX( Id ) FROM [User]; // You forgot the brackets in this part,Useris a reserved word in TSQL
If you want to reseed to different number you can use below:
dbcc checkident(tab1, reseed, 100)
I have one table called test, which has 4 columns:
id INT
v_out INT
v_in INT
label CHARACTER
I'm trying to update the table with the following query:
String sql = "
update
test
set
v_out = temp.outV
, v_in = temp.inV
, label = temp.label
from (
values
(1,234,235,'[abc]') // these value are read from other places
,(2,234,5585,'[def]') //[abc] = object.toString();
) as temp (e_id, outV, inV, label)
where
id = temp.e_id;
When I execute it, I got the error:
org.postgresql.util.PSQLException: ERROR: syntax error at or near "["
before get this error, i already update over 3000 rows.
so whats the reason caused this? is it because "[" this character?
this is the original table:
create table edges(
id serial not null primary key,
vertex_out int,
vertex_in int,
label character varying(255),
constraint fk_vertex_out foreign key (vertex_out) references vertices(id) on delete cascade,
constraint fk_vertex_in foreign key (vertex_in) references vertices(id) on delete cascade
);
The most likely problem here is string interpolation in SQL query (it is a very bad practice).
Look at this example:
values
(1,234,235,'[abc]''),
(2,234,5585,'[def]')
The ' symbol in the name of the first object breaches the string boundaries causing ERROR: syntax error at or near "[": on the second line.
You can search for SQL Injection in the internet to get details about this problem.

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.
