We have application running on weblogic . At times ( once in 2-3 weeks ) all of the sudden I start getting below in stack trace. Even after multiple try I only get "JZ0R2: No result set for this query" but data is there in DB for the row. And to resolve I simply refresh weblogic connection pools and things start working as expected. Can someone help with any tentative reason for this behavior.
DB : Sybase DB version 15.7
Java: 1.7

Try one of these:
conn.setAutoCommit( true );
or set various isolation levels, like this one, for instance:
conn.setTransactionIsolation(0);

I am using Mybatis with springboot to connect with an Oracle database. In that process I need to update multiple fields in bulk.
I have created a procedure to implement that functionality on the database side. When calling that procedure from the DAO layer, the following exception occurs:
org.springframework.jdbc.UncategorizedSQLException:
Error getting generated key or setting result parameter object.
Cause
Java.sql.SQLException: operation not allowed.
<insert id="update" parameter="java.util.map" statement="callable">
{ call test.bulk_update_procedure(#{customerid, mode=IN , jdbcType= varchar},#{firstname, mode= IN, jdbcType= varchar},#{age,mode=IN, jdbcType=varchar})
</insert>
When constructing a rather large table in netezza, I get the following ERROR when using a JDBC connection:
org.netezza.error.NzSQLException: The update count exceeded Integer.MAX_VALUE.
The table does get created properly, but the code throws an exception. When I try running the same SQL using nzsql I get:
INSERT 0 2395423258
i.e. no thrown exceptions. It seems the variable storing the count of records in JDBC is not large enough?
Has anyone else encountered this error? How did you deal with it?
Modify your connection string to include ignoreUpdateCount=on as a parameter and try again.
I am debugging a Big Data code in Production environment of my company. Hive return the following error:
Exception: org.apache.hadoop.hive.ql.lockmgr.LockException: No record of lock could be found, may have timed out
Killing DAG...
Execution has failed.
Exception in thread "main" java.sql.SQLException: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.tez.TezTask.

After investigation, I have found that this error could be caused by BoneCP in connectionPoolingType property, but the cluster support team told me that they fixed this bug by upgrading BoneCP.
My question is: can we INSERT INTO an external table in Hive, because I have doubt about the insertion script ?
Yes, you can insert into external table.
I'm runnig a Spring Boot batch with two different connections. An Oracle DB and a DB2 DB both using SimpleJDBCTemplate.
The problem happens when I make a query for the second time about 1 hour after the first one happens because I have 300,000 inserts before runs the second time.
The Oracle connection keeps alive for so many time that I believe it throws the IOException.
I'm thinking about closing the Oracle connection before those 300,000 inserts...
Here is the stacktrace:
Io exception: EDC8120I Connection ended abnormally.; nested exception
is java.sql.SQLException: Io exception: EDC8120I Connection ended
abnormally.

Use batch insert by 1000 items in each iteration.

we recently upgraded the IDE and OS of a java console application that runs 10 times a month.
now None of our queries work properly since hibernate converts the letter i to İ which is not I. All insert statements and id fields affected negatively.
now in our queries
id -> İD not ID
insert -> İNSERT not INSERT
neither select statements nor inserts do not execute.
for example:
in the previous version Select id from table a is now sent to the db as
SELECT İD from table a ,
and we dont have such a column called İD at all.
stack trace is as follows
Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00904: "İD": geçersiz belirleyici (invalid identifier)
Query: ReadObjectQuery(name="readObject" referenceClass=OrtakEntity sql="SELECT İD, ADİ, ALACAKLARİNDAHACİZVARMİ, ANNEADİ, FROM A WHERE (İD = ?)")

I resolved the issue by changing the settings of the computer to English and United States as location. (still not the best approach but now the program runs)
