The problem that I can see is that the table is created with the name 'article' and the query is done with ARTICLE in capital letter. I tried to change the application.properties file to this:
spring.datasource.url=jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DATABASE_TO_UPPER=false;MODE=MySQL;NON_KEYWORDS=USER;IGNORECASE=TRUE;CASE_INSENSITIVE_IDENTIFIERS=TRUE;DATABASE_TO_LOWER=TRUE
but it doesn't help the problem.
Here is some output from the console that demonstrate the table has been created:
Hibernate: create table "article" ("id" bigint generated by default as identity, "content" clob, "language" integer, "last_edited" timestamp, "published" timestamp, "title" varchar(255), "image_id" bigint, "user_id" bigint not null, primary key ("id"))
and later this pops up:
Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "ARTICLE" not found; SQL statement: select * from Article where language=? ORDER BY published desc
I tried to name the table in uppercase letter with
DATABASE_TO_LOWER=FALSE, DATABASE_TO_UPPER=TRUE;
and it didn't help either.
What could I try next?

I inherited a project where in UnitTests an H2 database is being used. On the startup of the project a lot of tables are created and populated with data.
CREATE TABLE SRC_FIELD_VALUE
( ID NUMBER IDENTITY,
INPUT_SRC_FIELD_REF_ID NUMBER,
VALUE VARCHAR2(255),
DESCRIPTION VARCHAR2(255)
);
We recently migrated to the latest version of H2 : 2.1.214
In my POM.XML I added "NON_KEYWORDS=VALUE,ID" to the end of definition but still got an exception :
Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Syntax error in SQL statement "CREATE TABLE SRC_FIELD_VALUE ( ID NUMBER IDENTITY, INPUT_SRC_FIELD_REF_ID NUMBER, [*]VALUE VARCHAR2(255), DESCRIPTION VARCHAR2(255) )"; expected "identifier"; SQL statement:
CREATE TABLE TC_RULE_COMP_DATA ( ID NUMBER IDENTITY, RULE_REF_ID NUMBER, SORT_ORDER NUMBER, VALUE CLOB ) [42001-214]
I also tried to put double quote around "VALUE" but got the same exception. It's interesting that "ID" is not getting considered as KEYWORD though.
What are my options here? I can't rename the fields.
I am using Spring Boot's schema.sql magic to create an in memory H2 database. The script contains the following statements:
create table PERSON
(
ID BIGINT not null primary key,
NAME VARCHAR(255) not null
);
create index IDX_PERSON_NAME on PERSON (NAME);
Upon launch Spring Boo fails with the following exception:
Caused by: org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #2 of URL [file:/D:/git/.../build/resources/main/schema.sql]: create index IDX_PERSON_NAME on PERSON (NAME); nested exception is org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "PERSON" not found; SQL statement:
create index IDX_PERSON_NAME on PERSON (NAME) [42102-200]
How can the statement fail to find the table that was created in the preceding statement?
Simply because NAME is not mentioned as Unique constraint, you have only specified it as NOT NULL constraint
create table PERSON
(
ID BIGINT not null primary key,
NAME VARCHAR(255) not null,
CONSTRAINT Person_Name_Unique UNIQUE (NAME)
);
create index IDX_PERSON_NAME on PERSON (NAME);
Here are the possible reasons,
The schema needs to be mentioned on while referring to table like test_schema.person
Your syntax for creating the index might be wrong. Refer to this link for H2 Syntax,https://www.baeldung.com/spring-yaml
I wonder if someone could explain the behaviour of the H2 JDBC driver when deleting an entry from a rather simple table.
When using the following table definition, the method executeUpdate() for a PreparedStatement instance returns 1 if one entry has been deleted (expected behaviour).
CREATE TABLE IF NOT EXISTS "MATERIAL" (
"CODE" VARCHAR(5) NOT NULL,
"NAME" VARCHAR(100) NOT NULL
);
When adding a PRIMARY KEY constraint on the CODE column, the same method returns 0 although the entry gets deleted successfully (behaviour not expected).
CREATE TABLE IF NOT EXISTS "MATERIAL" (
"CODE" VARCHAR(5) NOT NULL,
"NAME" VARCHAR(100) NOT NULL,
PRIMARY KEY ("CODE")
);
Most interestingly, when adding an INT typed column to serve as PRIMARY KEY the return value is 1 again:
CREATE TABLE IF NOT EXISTS "MATERIAL" (
"ID" INT NOT NULL AUTO_INCREMENT,
"CODE" VARCHAR(5) NOT NULL,
"NAME" VARCHAR(100) NOT NULL,
PRIMARY KEY ("ID")
);
Is someone able to reconstruct this behaviour and probably somehow explain it to me?
I have included the current version of H2 DB using maven.
EDIT:
If I eventually add a UNIQUE constraint for the CODE column, the return value is 0 again ...
CREATE TABLE IF NOT EXISTS "MATERIAL" (
"ID" INT NOT NULL AUTO_INCREMENT,
"CODE" VARCHAR(5) NOT NULL UNIQUE,
"NAME" VARCHAR(100) NOT NULL,
PRIMARY KEY ("CODE")
);
EDIT 2:
The query used to delete an entry looks like the following (used in PreparedStatement):
DELETE FROM MATERIAL WHERE CODE = ?
SOLUTION:
I'm sorry to have you bothered with this. Actually, there was no problem with the table definition or the JDBC driver. It was my test data - from earlier testing I had wanted to INSERT two entries having the same CODE. It was a multiple row insert - obviously this failed, when CODE was the PK or having a UNIQUE index. Thus, in this cases executeUpdate() could only return 0 because there was no data in the table at all.
I have a spring boot application and I trying to initialize some data on application startup.
This is my application properties:
#Database connection
spring.datasource.url=jdbc:h2:mem:test_db
spring.datasource.username=...
spring.datasource.password=...
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.initialize=true
spring.datasource.schema=schema.sql
spring.datasource.data=schema.sql
#Hibernate configuration
#spring.jpa.hibernate.ddl-auto = none
This is schema.sql:
CREATE TABLE IF NOT EXISTS `Person` (
`id` INTEGER PRIMARY KEY AUTO_INCREMENT,
`first_name` VARCHAR(50) NOT NULL,
`age` INTEGER NOT NULL,
PRIMARY KEY(`id`)
);
and data.sql
INSERT INTO `Person` (
`id`,
`first_name`,
`age`
) VALUES (
1,
'John',
20
);
But I got 'Syntax error in SQL statement' on application startup:
19:08:45.642 6474 [main] INFO o.h.tool.hbm2ddl.SchemaExport - HHH000476: Executing import script '/import.sql'
19:08:45.643 6475 [main] ERROR o.h.tool.hbm2ddl.SchemaExport - HHH000388: Unsuccessful: CREATE TABLE Person (
19:08:45.643 6475 [main] ERROR o.h.tool.hbm2ddl.SchemaExport - Syntax error in SQL statement "CREATE TABLE PERSON ( [*]"; expected "identifier"
Syntax error in SQL statement "CREATE TABLE PERSON ( [*]"; expected "identifier"; SQL statement:
I can't understand, what's wrong with this SQL.
Try this code. Remove PRIMARY KEY(id) and execute it.
CREATE TABLE IF NOT EXISTS `Person` (
`id` INTEGER PRIMARY KEY AUTO_INCREMENT,
`first_name` VARCHAR(50) NOT NULL,
`age` INTEGER NOT NULL
);
This error results from the structure of the CREATE TABLE declaration.
It will be the result when you have an extra comma in the end of your SQL declaration--no column declaration following the comma. For example:
CREATE TABLE IF NOT EXISTS `Person` (
`id` INTEGER PRIMARY KEY AUTO_INCREMENT,
`first_name` VARCHAR(50) NOT NULL,
`age` INTEGER NOT NULL, --note this line has a comma in the end
);
That's because CREATE TABLE expects a list of the columns that will be created along with the table, and the first parameter of the column is the identifier. As you check here, the column declaration follows the structure:
identifier datatype <constraints> <autoincrement> <functions>
Thus, in your case, as #budthapa and #Vishwanath Mataphati have mentioned, you could simply remove the PRIMARY KEY(id) line from the CREATE TABLE declaration. Moreover, you have already stated that id is a primary key on the first line of the column definitions.
In case you do not have a statement as the PRIMARY KEY declaration, be sure to check for the extra comma following your last column declaration.
Try this, as you have used Table_name
CREATE TABLE IF NOT EXISTS Person (
id INTEGER PRIMARY KEY AUTO_INCREMENT,
first_name VARCHAR(50) NOT NULL,
age INTEGER NOT NULL
);
I was add below in to application.properties and it work for me
spring.jpa.properties.hibernate.globally_quoted_identifiers=true
spring.jpa.properties.hibernate.globally_quoted_identifiers_skip_column_definitions = true
What helped in my case was removing single quotes from the table name in my insert query
I had to change this:
INSERT INTO 'translator' (name, email) VALUES ('John Smith', 'john#mail.com');
to this:
INSERT INTO translator (name, email) VALUES ('John Smith', 'john#mail.com');
You set auto increment id, so you can't insert new record with id.
Try INSERT INTO `Person` (
`first_name`,
`age`
) VALUES (
'John',
20
);
I ran into same issue. I fixed that with these application.properties:
spring.jpa.properties.hibernate.connection.charSet=UTF-8
spring.jpa.properties.hibernate.hbm2ddl.import_files_sql_extractor=org.hibernate.tool.hbm2ddl.MultipleLinesSqlCommandExtractor
Some issue with multi-line and default encoding.
On Oracle, I create a table like this:
CREATE TABLE "Mig1"(
"Id" INTEGER NOT NULL
, CONSTRAINT "PK_Mig1" PRIMARY KEY
(
"Id" )
)
Then, I rename the PK:
ALTER TABLE "Mig1" RENAME CONSTRAINT "PK_Mig1" TO "PK_XXX"
Then, I rename the table:
ALTER TABLE "Mig1" RENAME TO "XXX"
Then, I try to create another table that uses the name of the previously renamed table:
CREATE TABLE "Mig1"(
"Id" INTEGER NOT NULL
, CONSTRAINT "PK_Mig1" PRIMARY KEY
(
"Id" )
)
At this point I get: An error occurred: ORA-00955: name is already used by an existing object. And this is because somehow the primary key of the first table is still around in some way although it was renamed. If I try to create the second table like this:
CREATE TABLE "Mig1"(
"Id" INTEGER NOT NULL
, CONSTRAINT "YYY" PRIMARY KEY
(
"Id" )
)
it works. So how do I rename the primary key correctly with all of its associated resources such that its name can be reused?
There is an index associated with the primary key constraint, and it is probably still called "PK_Mig1". Try this:
ALTER INDEX "PK_Mig1" RENAME TO "PK_XXX";
