Springs SimpleJdbcInsert不会按预期产生自动生成的密钥

Question

I'm using springs SimpleJdbcInsert to execute an JDBC insert and return 2 auto-generated keys.

The command I use is:

KeyHolder keys = insert.withTableName("TRANSACTION").usingGeneratedKeyColumns("TRANSACTIONID", "ROWID").executeAndReturnKeyHolder(params);

But keys only contains one key named SCOPE_IDENTITY()

The logs seem to indicate that things are going well, except that the auto-generated keys for TRANSACTIONID AND ROWID don't get populated, here are some relevant logs

Answer 1

This was an issue with the H2 database I am using. It does not support returning more than one auto generated key.

Answer 2

Try this.

This is a complete save method which saves companyCarrier object with two properties set. These properties have datatypes of Integer and String.

Generated key is then set on the id property of the companyCarrier object.

Object[] args = { companyCarrier.getCompanyId(),
            companyCarrier.getCarrierId() };
    Class<?>[] parameterTypes = { CompanyCarrier.class };
    int[] types = { Types.INTEGER, Types.VARCHAR };

    SqlUpdate su = new SqlUpdate();

    su.setJdbcTemplate(getJdbcTemplate());

    su.setSql(getSqlQuery(getClass(), "save", parameterTypes));

    setSqlTypes(su, types);

    su.setReturnGeneratedKeys(true);
    su.compile();

    KeyHolder keyHolder = new GeneratedKeyHolder();
    su.update(args, keyHolder);
    int id = keyHolder.getKey().intValue();

    if (su.isReturnGeneratedKeys()) {
        companyCarrier.setId(id);
    } else {
        throw new RuntimeException("No key generated for insert statement");
    }
