Java.SQL Error: Prepared Statement not in batch mode

Question

I am using Java with backend HSQL. My prepared statement was working fine earlier. Recently, I created dependencies between department and items table and made the dep_seq_id column from auto generated seq_id to a simple column(we are updating id through java code now). After these changes, all dependent table create/update are failing with error like "statement not in batch mode".

The tables structure are like this:

CREATE TABLE DEPARTMENT
  (
    DEP_SEQ_ID  INTEGER NOT NULL,
    DEPT_STATE  VARCHAR(6) NOT NULL,
    NAME        VARCHAR(20) NOT NULL,
    YEAR        VARCHAR(4),
    CREATE_DATE DATE,
    LINK        VARCHAR(255),
    PRIMARY KEY(SEQ_ID,DEPT_STATE)
  );

CREATE TABLE ITEMS
  (
    ITEM_ID    INTEGER NOT NULL,
    ITEM_STATE VARCHAR(6) NOT NULL,
    NAME       VARCHAR(20),
    ITEM_CODE  VARCHAR(10),
    DEP_SEQ_ID INTEGER,
    DEPT_STATE VARCHAR(6),
    FOREIGN KEY(DEP_SEQ_ID,DEPT_STATE) REFERENCES DEPARTMENT(SEQ_ID, DEPT_STATE) ON
  DELETE CASCADE ON
  UPDATE CASCADE
  );

I do not understand what I am doing wrong here. Following is the code where I am trying to insert data in Items table, partial code is shown below. I hope it makes sense, I have changed names and columns, as I cant share the actual code.

 PreparedStatement statement = null;
    ResultSet generatedKeys = null;
    Long mappingId = null;

    try {
        statement = m_connection.prepareStatement("insert into ITEMS (ITEM_ID, ITEM_STATE, NAME, ITEM_CODE, DEP_SEQ_ID, DEPT_STATE) values(?,?,?,?,?,?)");
        for(WersMapping wersMapping : wersMapList){

        statement.setLong(1, item.getItemId());
        statement.setInt(2, item.getState());
        statement.setString(3, item.getName());
        statement.setString(4, item.getItemCode());

        statement.setInt(5, item.getDeptId());
        statement.setString(6, item.getDeptState());
        statement.addBatch();
        }

    int[] nArray = statement.executeBatch();
    int totalInserts = 0;
    if(nArray != null){

        for(int n:nArray){
            totalInserts = totalInserts + n;
        }
        LOGGER.log(Level.INFO, "Successfully created "+totalInserts + " Mapping instances");
    }
    return new Long(totalInserts) ;

You need to use executeBatch instead of executeUpdate.

Also make sure that your code calls addBatch at least one. See http://sourceforge.net/p/hsqldb/discussion/73673/thread/926b13f4/

sorry I wrote, excuteUpdate by mistake, in my code, it is using executeBatch. Corrected in the question as well.

kostya Over a year ago

Can you post full stack trace of the error you are getting?

As @Maverick mentioned in another comment most likely addBatch has been never called. See sourceforge.net/p/hsqldb/discussion/73673/thread/926b13f4

Use

 int affectedRows = statement.executeBatch();

The return type of executeBatch() is int[].

Try changing this.

I could not copy paste the code, so made a mistake there. Please ignore if you see any syntax error. The code compiles fine.I am facing runtime error.

Maverick Over a year ago

Can you check if the batch is empty ? This exception is also caused when the batch is empty i.e. there are no items in the batch. check at : for(WersMapping wersMapping : wersMapList){

RohitS Over a year ago

Thanks @Maverick, I noticed that there is some data issue in my local, hence the batch itself was empty.
