Question

在处理PreparedStatement时，我遇到了一个奇怪的错误。

这是在Squirrel SQL中运行的查询：

SELECT CUSTOMER, MAX(TRANSACTION_COUNT) as UNIT_COUNT, '2018-05-20' as EVENT_DATE, 'XYZ File Transfer' as TYPE, 'Financial Report' as EVENT 
FROM  REPORT_TABLE RT  
WHERE upper(REPORT_STATUS) = 'READY' and TRUNC(CREATED_TS) = '2018-05-20' and TRANSACTION_COUNT > 0 
GROUP BY CUSTOMER

这是我的PreparedStatement：

SELECT CUSTOMER, MAX(TRANSACTION_COUNT) as UNIT_COUNT, :date as EVENT_DATE, 'XYZ File Transfer' as TYPE, 'Financial Report' as EVENT 
FROM  REPORT_TABLE RT  
WHERE upper(REPORT_STATUS) = 'READY' and TRUNC(CREATED_TS) = :date and TRANSACTION_COUNT > 0 
GROUP BY CUSTOMER

参数设置为：

params.addValue（＆＃34; date＆＃34;，＆＃34; 2018-05-20＆＃34;）;

当我将它作为PreparedStatement运行时，我收到以下错误消息：

nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-418, S    QLSTATE=42610, SQLERRMC=unresolved untyped expression, DRIVER=4.19.66

我尝试查看有关错误消息的一些IBM资源，但没有任何内容与我手头的问题相关。

感谢您的帮助。

尝试使用CAST或DATE（）告诉编译器预期的类型，例如：

SELECT CUSTOMER, MAX(TRANSACTION_COUNT) as UNIT_COUNT, DATE(:date) as EVENT_DATE, 'XYZ File Transfer' as TYPE, 'Financial Report' as EVENT 
FROM  REPORT_TABLE RT  
WHERE upper(REPORT_STATUS) = 'READY' and TRUNC(CREATED_TS) = CAST(:date as DATE) and TRANSACTION_COUNT > 0 
GROUP BY CUSTOMER

DB2 SQL - PreparedStatement未解决的无类型表达式错误
