如何检查哪一列导致 db2 22001 错误？

Question

再会，

org.springframework.dao.DataIntegrityViolationException: could not insert: [com.entity.payment.BPaymentItem]; SQL [insert into sc.PHistoryItem (amount, beneficiaryAccNo, beneficiaryBankCode, beneficiaryBankName, beneficiaryRef2, billCode, branchId, chargeTo, cibRefNo, cifId, collectionAccountNo, companyId, companyName, createdHostDateTime, currentStatus, customerCategoryCharges, customerCategoryCode, customerCategoryId, customerCategoryName, description, errorCode, errorMessage, fromAccountName, fromAccountNo, fromAccountType, fromFavourite, gst, gstAmount, gstInclusive, gstName, gstRate, gstRefNo, gstTaxCode, hostRefNo, nbpsBillerCode, nbpsBillerName, nbpsReferenceNo, nbpsRrn2, nbpsRtn, nbpsSystemReferenceNo, notifyRetryCount, paymentDate, paymentHistoryId, processDate, promotionCharges, promotionCode, promotionId, promotionName, ref1, ref2, reference, rejectReason, remittanceStatus, remittanceTo, rfi, rrnInfo, rtTrxCode, rtnStatus, serviceCharge, serviceChargeCode, serviceChargeGLAcct, serviceChargeId, serviceChargeName, servicePackageCode, servicePackageId, servicePackageName, serviceType, showTerm, smsCharges, smsGst, smsGstAmount, smsGstInclusive, smsGstRate, smsGstTaxCode, toAccountName, toAccountNo, toAccountType, transferType, type, validateSig, approvalItemId) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)]; nested exception is org.hibernate.exception.DataException: could not insert: [com.entity.payment.BPaymentItem]

SQLSTATE 22001 是由字符数据引起的，发生了右截断；例如，更新或插入值是一个对于列来说太长的字符串，或者日期时间值不能分配给主变量，因为它太小了。

但是有没有办法检查导致此错误的列？

Answer 1

无法从此错误消息中确定导致问题的列。但基于此错误：SQLERRMC=null。您的数据正在尝试插入空值，要么您的列不接受空值，要么您没有传递正确的空值类型。

如果您使用这样的准备好的语句，那么要插入空值，您需要指定它。

String query = "insert into table_temp(col1,col2) values(?,?)";
pstmt = con.prepareStatement(query);
pstmt.setString(1, "a");
pstmt.setNull(2, java.sql.Types.NULL);
