I'm trying to run a JUnit test class for my Spring-Batch application. I had to create the following tables: http://static.springsource.org/spring-batch/reference/html/metaDataSchema.html. I create them in my initialization database script, including the following:
CREATE SEQUENCE BATCH_STEP_EXECUTION_SEQ;
CREATE SEQUENCE BATCH_JOB_EXECUTION;
CREATE SEQUENCE BATCH_JOB_SEQ;
The creation of all sequences and tables didn't generate any errors. But while executing my JUnit test, I get the following error:
org.springframework.dao.DataAccessResourceFailureException: Could not obtain identity(); nested exception is java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: BATCH_JOB_SEQ
at org.springframework.jdbc.support.incrementer.HsqlMaxValueIncrementer.getNextKey(HsqlMaxValueIncrementer.java:119)
That is caused when the class HsqlMaxValueIncrementer runs:
stmt.executeUpdate("insert into " + getIncrementerName() + " values(null)");
What am I doing wrong?
Thanks!!
For HSQLDB the 3 tables need the ID field.
CREATE TABLE BATCH_STEP_EXECUTION_SEQ (
ID BIGINT IDENTITY
);
CREATE TABLE BATCH_JOB_EXECUTION_SEQ (
ID BIGINT IDENTITY
);
CREATE TABLE BATCH_JOB_SEQ (
ID BIGINT IDENTITY
);

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 run into this issue:
Caused by: java.lang.IllegalArgumentException:
Error: User error in query:
CREATE TABLE failed for table TEST:
Table exists but definitions do not match
I added 2 new columns in my existing database using console, and added them in table creation statement. It hits the error when I run creating table again.
I checked everything, they all match, (name, type…)
the order of columns matter when you create a table. Did you validate this ? The IF NOT EXISTS in the CREATE TABLE clause checks for the same structure of the table. Please refer the documentation below for more details.https://docs.oracle.com/en/database/other-databases/nosql-database/21.1/sqlreferencefornosql/create-table.html
This inform you that the table that you are trying to create exits but the structure is not the same. It could be useful.
A sample to show the error when order of columns is changed:
sql-> CREATE TABLE IF NOT EXISTS testing_tbl(id INTEGER, firstName STRING,
lastName STRING,
PRIMARY KEY (id));
Statement completed successfully
sql-> CREATE TABLE IF NOT EXISTS testing_tbl(id INTEGER, firstName STRING,
lastName STRING,
PRIMARY KEY (id));
Statement did not require execution
sql-> CREATE TABLE IF NOT EXISTS testing_tbl(id INTEGER, lastName STRING,
firstName STRING,
PRIMARY KEY (id));
Error handling command CREATE TABLE IF NOT EXISTS testing_tbl(id INTEGER,
lastName STRING,
firstName STRING,
PRIMARY KEY (id)): Error: User error in query: CREATE TABLE failed for table testing_tbl: Table exists but definitions do not match
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 created tables on heroku using the following DDL.
CREATE TABLE IF NOT EXISTS "Team"(
"id" SERIAL,
"name" varchar(50) NOT NULL,
"description" varchar(255)
);
CREATE TABLE IF NOT EXISTS "Member"(
"id" SERIAL,
"name" varchar(50) NOT NULL,
"emp_number" integer NOT NULL,
"position" varchar(100) NOT NULL,
"team_id" integer references "Team"("id")
);
I got the following error:

The error is quite obvious. The SQL contains errors. I am quite new to postgres sql. At least I know the current version used by heroku supports if not exists syntax but I am not sure where I went wrong.
Is anybody good at PostgreSQL here?
If you had run this query directly, you would have gotten the error:
ERROR: there is no unique constraint matching given keys for referenced table "Team"
This gives you a clue that there's something missing to identify the columns in the "Team" table uniquely. You have declared that the ids of the tables are serials, but forgot to add primary key constraints. Adding this, will let you execute the query:
CREATE TABLE IF NOT EXISTS "Team"(
"id" SERIAL primary key,
...
);
CREATE TABLE IF NOT EXISTS "Member"(
"id" SERIAL primary key,
...
);
I have a somewhat complex structure as follows :
create or replace type user_typ as object(
user_id number(19,0),
username nvarchar2(40 char)
);
I inherit an applicant_typ from this :
create or replace type applicant_typ under user_typ (
resume_text nclob
);
My design involves jobs to which applicants can apply. To this end, I create an application_typ as follows :
create or replace TYPE Application_typ AS OBJECT (
application_id NUMBER,
candidate applicant_typ,
time_of_app DATE
);
CREATE TYPE Application_tab IS TABLE OF Application_typ;
And now I want to create an object type called Job_typ, and a table containing those objects, wherein there will be a nested table for applications :
CREATE OR REPLACE TYPE Job_typ AS OBJECT (
job_ID NUMBER,
company_ID NUMBER,
description NVARCHAR2(1000),
name NVARCHAR2(200),
application Application_tab,
MAP MEMBER FUNCTION job_no RETURN NUMBER,
MEMBER PROCEDURE no_of_applicants
);
All of this works fine. The issue is when I try to create a table of type Job_typ :
CREATE TABLE Job_tab OF Job_typ
NESTED TABLE application STORE AS application_nt;
This doesn't work, giving the error :
SQL Error: ORA-02320: failure in creating storage table for nested table column APPLICATION
ORA-22913: must specify table name for nested table column or attribute
02320. 00000 - "failure in creating storage table for nested table column %s"
*Cause: An error occurred while creating the storage table for the
specified nested table column.
What am I doing wrong?
EDIT : I tried some different things. If I change application_typ as follows :
CREATE OR REPLACE TYPE Application_typ AS OBJECT (
application_id NUMBER,
candidate User_Typ, -- NOTE: This attribute is now of type User_typ instead of the inherited type
time_of_app DATE,
);
CREATE TYPE Application_tab IS TABLE OF Application_typ;
Then everything else works, and I am able to create the Job table. Why do I get the error on using the inherited type?
I tried the following in Oracle 11.2.0.1 and didn't get any error. I made a slight change though:
CREATE OR REPLACE TYPE user_typ AS OBJECT
(
user_id NUMBER (19, 0),
username NVARCHAR2 (40 CHAR)
) NOT FINAL; -- << Notice the NOT FINAL keyword
create or replace type applicant_typ under user_typ (
resume_text nclob
);
CREATE OR REPLACE TYPE Application_typ AS OBJECT
(
application_id NUMBER,
candidate applicant_typ,
time_of_app DATE
);
CREATE TYPE Application_tab IS TABLE OF Application_typ;
CREATE OR REPLACE TYPE Job_typ AS OBJECT
(
job_ID NUMBER,
company_ID NUMBER,
description NVARCHAR2 (1000),
name NVARCHAR2 (200),
application Application_tab,
MAP MEMBER FUNCTION job_no
RETURN NUMBER,
MEMBER PROCEDURE no_of_applicants
);
CREATE TABLE Job_tab OF Job_typ
NESTED TABLE application
STORE AS application_nt;
While trying to create all your types and keywords, I got the error:
[Error] PLS-00590 (10.1): PLS-00590: attempting to create a subtype UNDER a FINAL type
This is because Oracle doesn't allow creation of a subtype on a FINAL type. If you don't define any finalizing clause for the base type, the default is FINAL.
Read more on Oracle Docs.
If you are coding for the real world (read industry), I'd advise against using nested tables as column types. You end up spending your entire life trying to nest and un-nest these. I'd suggest you normalize your schema as much as you can or need and leave nested tables for operations in PL/SQL code blocks.
