    <p>I'm using JDBC to execute queries on Amazon Redshift. I have a java.sql.PreparedStatement object. When I set the parameters on the PreparedStatement object and then call:</p> <pre><code>preparedStatement.executeQuery(); </code></pre> <p>with this query:</p> <pre><code>SELECT start_date from sometable_:year order by start_date desc limit 1 </code></pre> <p>in the end, the query should look like this:</p> <pre><code>SELECT start_date from sometable_2010 order by start_date desc limit 1 </code></pre> <p>I get this exception:</p> <pre><code>org.postgresql.util.PSQLException: ERROR: relation "sometable_$1" does not exist at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1592) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1327) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:192) at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:451) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:350) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:254) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.postgresql.ds.jdbc23.AbstractJdbc23PooledConnection$StatementHandler.invoke(AbstractJdbc23PooledConnection.java:477) at com.sun.proxy.$Proxy159.executeQuery(Unknown Source) at org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.executeQuery(WrappedPreparedStatement.java:342) at com.example.persistence.dao.impl.Redshift01JdbcDaoImpl.getSomeTableLastArchiveDate(Redshift01JdbcDaoImpl.java:46) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:309) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:183) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:150) at org.springframework.dao.support.PersistenceExceptionTranslationInterceptor.invoke(PersistenceExceptionTranslationInterceptor.java:155) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:172) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:202) at com.sun.proxy.$Proxy314.getSomeTableLastArchiveDate(Unknown Source) at com.example.service.impl.someTableArchiveServiceImpl.process(SomeTableArchiveServiceImpl.java:69) at com.example.service.impl.AbstractBatchServiceImpl.run(AbstractBatchServiceImpl.java:106) at com.example.service.jms.JmsMessageListener.callBatchService(JmsMessageListener.java:72) at com.example.service.jms.JmsMessageListener.onMessage(JmsMessageListener.java:136) at org.springframework.jms.listener.adapter.MessageListenerAdapter.onMessage(MessageListenerAdapter.java:339) at org.springframework.jms.listener.AbstractMessageListenerContainer.doInvokeListener(AbstractMessageListenerContainer.java:535) at org.springframework.jms.listener.AbstractMessageListenerContainer.invokeListener(AbstractMessageListenerContainer.java:495) at org.springframework.jms.listener.AbstractMessageListenerContainer.doExecuteListener(AbstractMessageListenerContainer.java:467) at org.springframework.jms.listener.AbstractPollingMessageListenerContainer.doReceiveAndExecute(AbstractPollingMessageListenerContainer.java:325) at org.springframework.jms.listener.AbstractPollingMessageListenerContainer.receiveAndExecute(AbstractPollingMessageListenerContainer.java:263) at org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker.invokeListener(DefaultMessageListenerContainer.java:1058) at org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker.executeOngoingLoop(DefaultMessageListenerContainer.java:1050) at org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker.run(DefaultMessageListenerContainer.java:947) at java.lang.Thread.run(Thread.java:722) </code></pre> <p>I would rather not do string concatenation, what am I doing wrong? The PreparedStatement setParameters method works for all other JDBC queries in my code base.</p> <p>Thank you,</p> <p>Tom</p>

    1. COYour query doesn't look like a valid SQL query. And the table name in the error message is different from the one shown in the code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
