Question

Postgres SQL Error: morg.postgresql.util.PSQLException: ERROR: operator does not exist: integer = character varying

Asked by: sudhakar_koundinya

Dear All,

Here are the details.

My Java Version is 1.6.x
My Tomcat Version is 5.5.27
Postgres JDBC Version is  postgresql-8.1-408.jdbc3.jar

 I am working with above versions for my clients for an application development. I can't change any of the versions because all have become inter-dependable.  .

when executing the application in tomcat server, I am getting following exceptions.

rg.postgresql.util.PSQLException: ERROR: operator does not exist: integer = character varying
      at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1531)
      at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1313)
      at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:188)
      at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:452)
      at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:354)
      at org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:258)
      at org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:93)


Note: I know why this exception is coming and how to resolve the error. But I don't have permissions to touch that code base. The same code is working at client place.

I am not having any clue where exactly I am  missing. I request somebody to help me on this.

Thanks & Kind Regards
Sudhakar Chavali

The below code is an error on my machine. And I know the work arround also. But without changing any code, is there any other solution which helps me to resolve my issue?
 
 pstmt = connection.prepareStatement(sql);
      if(params != null) {
        for (int i = 0; i < params.length; i++) {
          if (params[i] != null) {
            pstmt.setString(i + 1, params[i]);
          }
        }
      }

Sounds like a SQL syntax error to me. Can you post the SQL statement that you are trying to execute?

 

by: jim_cakalicPosted on 2009-02-27 at 13:48:13ID: 23759877

Since you say that it is working at a client site, perhaps there is a database difference between your environment and the deployed environment? The exception is saying that your SQL is trying to compare an integer value/column with a varchar value/column which can't be done without casting.

>             pstmt.setString(i + 1, params[i]);

try using setObject() instead

            pstmt.setObject(i + 1, params[i]);

Hello Jim & Objects

Thanks for the responses. As mentioned in my request I know how to close the issue, but I should not modify the code. Infact I can't (because client provided me compiled library file)

Using JAD  I am able to find issue. So I would request if you have any alternate solution such as using appropriate JDBC library, Java version etc.

Thanks & Kind Regards
Sudhakar Chavali

which is what?

>which is what?
JAD is a java decompiler..

@sudhakar, As Jim mentioned, I think your dbase structure is different on your machine and wherever this code is working.. & without modifying the code, only way I can think to fix this is to change the dbase structure..

So if I read your question correctly, this code is working at one place and not working at another?

Even if thats the case, I understand you are saying that you can not change the code OR the versions of jar files...

then obviously it can not be fixed without changing something ( only one way is to convert all the columns to type varchar in your database)

 

by: sudhakar_koundinyaPosted on 2009-04-23 at 23:23:52ID: 24222178

I am able to fix this issue. There is protocolVersion mismatch on my machine conf files. Once I set conf file correctly, I am not seeing any issues.

This is what I need to set
jdbc:postgresql://<IP Address>:5432/<DB>?stringtype=unspecified&protcolVersion=3
