CREATE TABLE Attach_Files
(
FileID INT IDENTITY(1,1) NOT NULL,
Name NVARCHAR(50) NOT NULL,
Files VARBINARY(MAX) NOT NULL
);
Your code works in Microsoft SQL Server db<>fiddle
It does not work in Oracle as it is a different RDBMS with different syntax and you need to fix the syntax errors on most lines:
Identity columns need to be GENERATED [ALWAYS|BY DEFAULT] AS IDENTITY [(other options)]
NVARCHAR should be NVARCHAR2
VARBINARY(MAX) should be BLOB
You want:
CREATE TABLE Attach_Files
(
FileID INTEGER
GENERATED ALWAYS AS IDENTITY
NOT NULL,
Name NVARCHAR2(50)
NOT NULL,
Files BLOB NOT NULL
);
db<>fiddle here
That IDENTITY(1,1) looks more like SQL Server syntax.
For Oracle, use .. IDENTITY START WITH a INCREMENT BY n
Of course, can change a and n to the appropriate values for your case (a=1 and n=1).
Try this statement:
CREATE TABLE Attach_Files
(
FileID INTEGER GENERATED ALWAYS AS IDENTITY
(START WITH 1
INCREMENT BY 1
MAXVALUE 1000000
CACHE 1
CYCLE) NOT NULL,
Name NVARCHAR(50) NOT NULL,
Files VARBINARY(MAX) NOT NULL
);
Thank you.

I created an in memory H2 database with JDBC URL
jdbc:h2:~/test;MODE=PostgreSQL;DATABASE_TO_LOWER=TRUE;DEFAULT_NULL_ORDERING=HIGH
The H2 web console refuses to let me do an auto_increment. I've seen serial for Postgres, but that doesn't work either.
At it's simplest, it hates:
create table test(id bigint auto_increment);
Syntax error in SQL statement "create table test(id bigint [*]auto_increment)"; expected "ARRAY, INVISIBLE, VISIBLE, NOT NULL, NULL, AS, DEFAULT, GENERATED, ON UPDATE, NOT NULL, NULL, DEFAULT ON NULL, NULL_TO_DEFAULT, SEQUENCE, SELECTIVITY, COMMENT, CONSTRAINT, COMMENT, PRIMARY KEY, UNIQUE, NOT NULL, NULL, CHECK, REFERENCES, ,, )"; SQL statement:
create table test(id bigint auto_increment) [42001-214] 42001/42001 (Help)
Why do I care:
My code base was failing with NULL not allowed for column "REV". I'm using JPA/Hibernate + Liquibase. In order to try the suggestions at
Hibernate Envers + Liquibase: NULL not allowed for column "REV"
I'm trying to add an auto_increment to my Liquibase changelog file.
You can use the SQL Standard's generation clause GENERATED ALWAYS AS IDENTITY. For example:
create table test (
id bigint generated always as identity,
name varchar(10)
);
See PostgreSQL Example.
It works the same way in H2. For example:
create table test(id bigint generated always as identity, name varchar(10));
insert into test (name) values ('Chicago') ;
select * from test;
Result:
ID NAME
-- -------
1 Chicago
unexpected beginning of statement
the coding
If you are using SQL then the issue is with create query where you passes int(10)
you can not pass any size to int type of fields
create table acc
(acc_id int not null primary key,
username_acc varchar(30) not null,
....)
Try with above
Thanks
I'm having a problem with a table I created. I am trying to run a query however a red line appears under my code ('excursionID', and 'excursions'), claiming 'Invalid Column name 'excursionID' and 'Invalid object name 'dbo.excursions' even though I have created the table already!
Here is the query
SELECT
excursionID
FROM [dbo].[excursions]
Here is the query I used to create the table
USE [zachtravelagency]
CREATE TABLE excursions (
[excursionID] INTEGER NOT NULL IDENTITY (1,1) PRIMARY KEY,
[companyName] NVARCHAR (30) NOT NULL,
[location] NVARCHAR (30) NOT NULL,
[description] NVARCHAR (30) NOT NULL,
[date] DATE NOT NULL,
[totalCost] DECIMAL NOT NULL,
I've tried dropping the table and inserting table again.
For some reason all my other tables work, it's just this table that doesn't identify itself. I'm very new to SQL so thank you for your patience!
You use DB [zachtravelagency] for create table.And You dont use this DB in your query. Default used db master in SSMS. Try
SELECT
excursionID
FROM [zachtravelagency].[excursions]
I have the following SQL I trigger in a C# app.
All works well but the ID table doesn't auto increment. It creates the value of 1 for the first entry then will not allow other inserts due to not being able to create a unquie ID.
Here is the SQL:
CREATE TABLE of_mapplist_raw (
id integer PRIMARY KEY NOT NULL,
form_name varchar(200) NOT NULL,
form_revi varchar(200) NOT NULL,
source_map varchar(200),
page_num varchar(200) NOT NULL,
fid varchar(200) NOT NULL,
fdesc varchar(200) NOT NULL
)";
I'm sure its a schoolboy error at play here.
you need to specify its seed and increment.( plus , i dont think there is integer keyword ....)
id [int] IDENTITY(1,1) NOT NULL,
the first value is the seed
the second one is the delta between increases
A Question you might ask :
delta between increases ? why do i need that ? its always 1 ....??
well - yes and no. sometimes you want to leave a gap between rows - so you can later insert rows between... specially if its clustered index by that key....and speed is important... so you can pre-design it to leave gaps.
p.s. ill be glad to hear other scenarios from watchers.
You need to mention the Identity.
id int IDENTITY(1,1) NOT NULL
CREATE TABLE PERMISSIONS(
ID BIGINT NOT NULL PRIMARY KEY,
NAME VARCHAR(255) NOT NULL, UNIQUE(ID)
)
CREATE TABLE ROLES(
ID BIGINT NOT NULL PRIMARY KEY,
NAME VARCHAR(255)
)
I want to run this in MySql. When I try to execute separately each create-query everything works fine but they don't work together. I thought that separator was missed and tried to put semicolon after each query but MySql says that I have syntax mistake near ";" . Where is the mistake?
using the queries in the mysql console with a semi-colon after the each statement works. maybe you use an api (like php's mysql_query) which only supports one query at the time.
It's a semi-colon.
What is the equivalent of 'go' in MySQL?
I don't have a MySql instance running here and it's by no means my cup of tea but I believe you're supposed to separate your queries with ;.
CREATE TABLE PERMISSIONS(
ID BIGINT NOT NULL PRIMARY KEY,
NAME VARCHAR(255) NOT NULL, UNIQUE(ID)
) ;
CREATE TABLE ROLES(
ID BIGINT NOT NULL PRIMARY KEY,
NAME VARCHAR(255)
)
