问题
I am trying to use hsqldb-2.3.4 to connect from Spring applicastion.
I created data base using the following details
Type : HSQL Database Engine Standalone
Driver: org.hsqldb.jdbcDriver
URL: jdbc:hsqldb:file:mydb
UserName: SA
Password: SA
I created a table named ALBUM under "MYDB" schema
In spring configuration file:
<bean id="jdbcTemplate"
class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
<constructor-arg ref="dbcpDataSource" />
</bean>
<bean id="dbcpDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.hsqldb.jdbcDriver" />
<property name="url" value="jdbc:hsqldb:file:mydb" />
<property name="username" value="SA" />
<property name="password" value="SA" />
</bean>
And in my spring controller I am doing jdbcTemplate.query("SELECT * FROM MYDB.ALBUM", new AlbumRowMapper());
And It gives me exception:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [SELECT * FROM MYDB.ALBUM]; nested exception is java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: ALBUM
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:982)
org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:861)
javax.servlet.http.HttpServlet.service(HttpServlet.java:622)
org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:846)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)
If I execute same query through SQL editor of hsqldb it executes fine. Can you please help me with this.
回答1:
user lacks privilege or object not found can have multiple causes, the most obvious being you're accessing a table that does not exist. A less evident reason is that, when you run your code, the connection to a file database URL actually can create a DB. The scenario you're experiencing might be you've set up a DB using HSQL Database Manager, added tables and rows, but it's not this specific instance your Java code is using. You may want to check that you don't have multiple copies of these files: mydb.log, mydb.lck, mydb.properties, etc in your workspace. In the case your Java code did create those files, the location depends on how you run your program. In a Maven project run inside Netbeans for example, the files are stored alongside the pom.xml.

If you've tried all the other answers on this question, then it is most likely that you are facing a case-sensitivity issue.
HSQLDB is case-sensitive by default. If you don't specify the double quotes around the name of a schema or column or table, then it will by default convert that to uppercase. If your object has been created in uppercase, then you are in luck. If it is in lowercase, then you will have to surround your object name with double quotes.
For example:
CREATE MEMORY TABLE "t1"("product_id" INTEGER NOT NULL)
To select from this table you will have to use the following query
select "product_id" from "t1"
回答3:
As said by a previous response there is many possible causes. One of them is that the table isn't created because of syntax incompatibility. If specific DB vendor syntax or specific capability is used, HSQLDB will not recognize it. Then while the creation code is executed you could see that the table is not created for this syntax reason. For exemple if the entity is annoted with @Column(columnDefinition = "TEXT") the creation of the table will fail.
There is a work around which tell to HSQLDB to be in a compatible mode for pgsl you should append your connection url with that
"spring.datasource.url=jdbc:hsqldb:mem:testdb;sql.syntax_pgs=true"
and for mysql with
"spring.datasource.url=jdbc:hsqldb:mem:testdb;sql.syntax_mys=true"
oracle
"spring.datasource.url=jdbc:hsqldb:mem:testdb;sql.syntax_ora=true"
note there is variant depending on your configuration
it could be hibernate.connection.url= or spring.datasource.url=
for those who don't use the hibernate schema creation but a SQL script you should use this kind of syntax in your script
SET DATABASE SQL SYNTAX ORA TRUE;
It will also fix issues due to vendor specific syntax in SQL request such as array_agg for posgresql
Nota bene : The the problem occurs very early when the code parse the model to create the schema and then is hidden in many lines of logs, then the unitTested code crash with a confusing and obscure exception "user lacks privilege or object not found error" which does not point the real problem at all. So make sure to read all the trace from the beginning and fix all possible issues

I had the error user lacks privilege or object not found while trying to create a table in an empty in-memory database.
I used spring.datasource.schema and the problem was that I missed a semicolon in my SQL file after the "CREATE TABLE"-Statement (which was followed by "CREATE INDEX").
回答5:
I had similar issue with the error 'org.hsqldb.HsqlException: user lacks privilege or object not found: DAYS_BETWEEN' turned out DAYS_BETWEEN is not recognized by hsqldb as a function. use DATEDIFF instead.
DATEDIFF ( <datetime value expr 1>, <datetime value expr 2> )
回答6:
When running a HSWLDB server. for example your java config file has:
hsql.jdbc.url = jdbc:hsqldb:hsql://localhost:9005/YOURDB;sql.enforce_strict_size=true;hsqldb.tx=mvcc
check to make sure that your set a server.dbname.#. for example my server.properties file:
server.database.0=eventsdb
server.dbname.0=eventsdb
server.port=9005
回答7:
I was inserting the data in hsql db using following script
INSERT INTO Greeting (text) VALUES ("Hello World");
I was getting issue related to the Hello World object not found and HSQL database user lacks privilege or object not found error
which I changed into the below script
INSERT INTO Greeting (text) VALUES ('Hello World');
And now it is working fine.
回答8:
I bumped into kind of the same problem recently. We are running a grails application and someone inserted a SQL script into the BootStrap file (that's the entry point for grails). That script was supposed to be run only in the production environment, however because of bad logic it was running in test as well. So the error I got was:
User lacks privilege or object not found:
without any more clarification...
I just had to make sure the script was not run in the test environment and it fixed the problem for me, though it took me 3 hours to figure it out. I know it is very, very specific issue but still if I can save someone a couple of hours of code digging that would be great.
回答9:
I was having the same mistake. In my case I was forgetting to put the apas in the strings.
I was doing String test = "inputTest";
The correct one is String test = "'inputTest'";
The error was occurring when I was trying to put something in the database
connection.createStatement.execute("INSERT INTO tableTest values(" + test +")";
In my case, just put the quotation marks ' to correct the error.
回答10:
In my case the error occured because i did NOT put the TABLE_NAME into double quotes "TABLE_NAME" and had the oracle schema prefix.
Not working:
SELECT * FROM FOOSCHEMA.BAR_TABLE
Working:
SELECT * FROM "BAR_TABLE"
回答11:
had this issue with concatenating variables in insert statement. this worked
// var1, var3, var4 are String variables
// var2 and var5 are Integer variables
result = statement.executeUpdate("INSERT INTO newTable VALUES ('"+var1+"',"+var2+",'"+var3+"','"+var4+"',"+var5 +")");
回答12:
In my case the issue was caused by the absence (I'd commented it out by mistake) of the following line in persistence.xml:
<property name="hibernate.hbm2ddl.auto" value="update"/>
which prevented Hibernate from emitting the DDL to create the required schema elements...
(different Hibernate wrappers will have different mechanisms to specify properties; I'm using JPA here)
