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)
)

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 feel like I am probably missing something really simple, but I really can't figure out what I'm doing wrong. I'm trying to use a check constraint to make sure zipcodes are 5 digit numbers, but the check restraint keeps failing. Here is the table creating with the constraint:
Create Table Students (
StudentID Int Primary Key Identity(1,1)
StudentNumber nVarchar(100) Unique Not Null,
...
StudentZipCode nChar(10) Not Null
)
Go
Alter Table Students Add Constraint chZipCode
CHECK (StudentZipCode LIKE '[0-9][0-9][0-9][0-9][0-9]' OR StudentZipCode
Like '[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]')
Go
Codes like 12345-6789 work, but when I try to insert the values like '12345' or '01234' it gives me this error:
The INSERT statement conflicted with the CHECK constraint "chZipCode". The conflict occurred in database ..., table "dbo.Students", column 'StudentZipCode'.
It fails because you defined the zip code as a char() instead of a varchar(). Hence, it has a bunch of spaces padding it out.
So, define it as:
Create Table Students (
StudentID Int Primary Key Identity(1,1),
StudentNumber nVarchar(100) Unique Not Null,
StudentZipCode nVarChar(10) Not Null,
CHECK (StudentZipCode LIKE '[0-9][0-9][0-9][0-9][0-9]' OR
StudentZipCode LIKE '[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]')
);
Then '12345' works, because it matches the first of the LIKE patterns.
'012344' does not work, because no pattern has six digits in a row.
Here is a SQL Fiddle.
I am trying to create table having different indexes with single query but H2 gives Error for example:
create table tbl_Cust
(
id int primary key auto_increment not null,
fid int,
c_name varchar(50),
INDEX (fid)
);
but this gives error as
Unknown data type: "("; SQL statement:
[Error Code: 50004]
[SQL State: HY004]
Due to this I have to run 2 different queries to create table with Index. First query to create table and then second query to add index with
create INDEX c_fid on tbl_Cust(fid);
Is there something wrong in my query or H2 simply does not support this creation of table with index in single query?
Interesting question. The solution is even more interesting, as it involves MySQL compatibility mode.
It's actually possible to perform the exact same command you wrote without any modification, provided you just add to your jdbc url the MySQL mode.
Example URL like this: jdbc:h2:mem:;mode=mysql
SQL remains:
create table tbl_Cust
(
id int primary key auto_increment not null,
fid int,
c_name varchar(50),
INDEX (fid)
);
Update count: 0
(15 ms)
Too bad I did not see this question earlier... Hopefully the solution might become handy one day to someone :-)
I could resolve the problem. According to
http://www.h2database.com/html/grammar.html#create_index
I modified the query. It works fine with my H2 server.
CREATE TABLE subscription_validator (
application_id int(11) NOT NULL,
api_id int(11) NOT NULL,
validator_id int(11) NOT NULL,
PRIMARY KEY (application_id,api_id),
CONSTRAINT subscription_validator_ibfk_1 FOREIGN KEY (validator_id) REFERENCES validator (id) ON UPDATE CASCADE
);
CREATE INDEX validator_id ON subscription_validator(validator_id);
I want to take the values from this site for the country table in my database.
The problem is that they don't provide the table structure, so I have to create one, but I cannot get it right - my phpMyAdmin keeps displaying an error when I want to inject the data into the table I created below:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'NUMERIC, alpha3, name, officialName) VALUES ('004','AFG','Afghanistan','Afghan' at line 1
--
-- Table structure for table `countrytable`
--
CREATE TABLE IF NOT EXISTS `countrytable` (
`NUMERIC` int(11) NOT NULL,
`alpha3` int(11) NOT NULL,
`name` varchar(255) DEFAULT NULL,
`officialName` varchar(255) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
I think my table structure is incorrect. How can I fix it? Thanks!
Try all varchar fields to get the data in since all fields are in quotes in the string you have.
NUMERIC is reserved word in mysql
add in back-tick or quote it -> http://dev.mysql.com/doc/refman/5.1/en/reserved-words.html
`alpha3` should be a varchar(3) (or larger), not an int(11).
