I have a problem to use PostgreSQL with JPA.
When i try to execute my app on glassfish i got this error:
Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: org.postgresql.util.PSQLException: ERROR: no schema has been selected to create in
Error Code: 0
Call: CREATE TABLE CABINET (ID INTEGER NOT NULL, PRIMARY KEY (ID))
Query: DataModifyQuery(sql="CREATE TABLE CABINET (ID INTEGER NOT NULL, PRIMARY KEY (ID))")
at org.eclipse.persistence.exceptions.DatabaseException.sqlException(DatabaseException.java:331)
at org.eclipse.persistence.internal.databaseaccess.DatabaseAccessor.executeDirectNoSelect(DatabaseAccessor.java:895)
So how can i specify the schema for JPA so it can be able to use postgresql
note: i have added the postgresql maven dependancy:
<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.1-901-1.jdbc4</version>
</dependency>
Please help me; Thank you
The schema is specified with the "search_path" variable in postgres.
To solve your problem, you have 2 solutions:
Permanently add the search to the user used by your connection:
ALTER user username set search_path=yourschema ;
Add temporarly the search_path in the jdbc connection (which i find ugly)
set search_path=yourschema;

I am new to spring data jpa.
i have a legacy database , which i am trying to connect to via spring data jpa.
i have a certain extension created in postgres which is used for some of the columns in my tables
for e.g
CREATE EXTENSION IF NOT EXISTS citext WITH SCHEMA public;
this extension is created mostly for (case-insensitive text)
now when i try to map the tables using standard entity annotations, it gives me error, as its unable to understand this extension
The error i get is
g.springframework.boot.SpringApplication - Application startup failed

i want a way via annotations to solve this issue, its ok if it is treated just as text column.
Hibernate is validating the schema on start-up as the ddl.auto property is set to validate.
You can either disable validation entirely or specify a column definition for the relevant #Columnproperty which should allow the validation to pass:
https://docs.oracle.com/javaee/5/api/javax/persistence/Column.html#columnDefinition()
#Column(columnDefinition = "citext") //or "other"?
private String myField;
Note that the column definition only affects DDL operations i.e. schema creation or validation.
Disabling validation entirely depends on your set-up. In a spring-boot app for example you set spring.jpa.hibernate.ddl-auto = false
I am trying to perform a basic connection between to a local postgresql DB from a very basic SpringBootProject (for training purpose).
# configure postgresql
spring.datasource.platform=postgres

So far, I have managed to have it compile and run... but when I am trying to access my DB, I get a "Table "FILMS" not found" error (org.h2.jdbc.JdbcSQLException). When I insert data from a data.sql, I get the inserted movies. But without this initializer, I cannot get data from my db...

Spring boot is in version 2.03 RELEASE; both postgresql connector AND server's ones are 9.4.
I am using spring boot parent starter, as well as data-jpa-starter (with no extra hibernate/jpa depencies defined).
The source code is here
My postresql server is up, the database "db" exists, and its table public."FILMS" is full of data...
Any idea on what I am doing (or undestanding) wrong?
In your application properties file try
spring.jpa.hibernate.ddl-auto=validate
It will try to check the table in your db

I'm getting a
JdbcSQLException: Schema "dbo" not found;
SQL statement: create table "dbo"."TableName"
when running some boilerplate sql against the h2 sqlserver emulator (ie, with config settings:
db.default.slickdriver=com.typesafe.slick.driver.ms.SQLServerDriver
db.default.driver=net.sourceforge.jtds.jdbc.Driver
db.default.url="jdbc:h2:file:~/data/test1;MODE=MSSQLServer"
running the following:
Database.forDataSource(DB.getDataSource())
withSession {
I've tried creating the schema:
Database.forDataSource(DB.getDataSource())
withSession {
implicit session =>
Q.updateNA("CREATE SCHEMA \"dbo\" AUTHORIZATION sa;")
}
but that doesn't seem to do the trick (or report an error message). Am I missing something?
still unable to create the schema programatically. was able to easily create it via the h2 console, using the exact same query as above.

Please avoid database URLs of this form (jdbc:h2:file:data/test1) as this is relative to the current working directory (and the working directory can change). Use jdbc:h2:/absolute/path instead, or jdbc:h2:~/data (relative to the current user home directory).
If you use double quotes for create table "dbo"."TableName", then you also need to use double quotes for create schema:

I'm working on a web project using EJB 3.0, and whenever EclipseLink tries to interact with the database, it says that the schema I'm using doesn't exist (which it does).
I get a massive, unhelpful stack trace from GlassFish 2.1, which begins with:
EclipseLink, version: Eclipse Persistence Services - 1.1.0.r3639-SNAPSHOT

I could post more of the stack trace, but it's really boring. Any ideas for why EclipseLink can't see the schema?
More info: "beamline" is the only schema I use. The SQL in the stack trace is the stuff that was generated by a NamedQuery, the first interaction with this database (and the first JPA interaction at all) in my program.
Got it - I'm connecting directly to the database, when I should be using GlassFish's connection pool.
