在 ireport 中使用 java 表达式时执行 sql 语句时出错

Question

我正在使用 iReport 进行报告开发。

我有 2 个参数，第一个参数 (companyName) 嵌入到第二个参数 (pCompanyName) 中。我还使用 2 个选项过滤参数。如果参数为空，它将打印出“”或空白，否则将打印查询。请参考下面的参数部分。使用groovy语言时，会打印出报告。

问题是在将语言从 groovy 更改为 java 表达式后报告打印出错误。下面是错误。有人在这里请帮助..绝望。

$P!{pCompanyName}

参数

1) $P{公司名称}

2) $P!{pCompanyName}

($P{companyName}.isEmpty() ? "" : " AND b.company_name = 'JA' ")

Answer 1

是的，我终于得到了与我上面的问题相对应的解决方案。

这是因为我没有在 if else 代码中放入括号，这就是为什么错误说 sql 语句错误，但我认为它不是 sql 语句错误，它是语法错误：

解决方案

改变这个：( $P{companyName}.isEmpty( ) ? "" : " AND b.company_name = 'JA' ")

为此：( ($P{companyName}.isEmpty( ) ) ? "" : " AND b.company_name = 'JA' ")
