Java Groovy-多表旋转到文件

我正在运行一个多表SQL调用，该调用将启动到file.write。这段代码在SQuirreL甚至Groovy中都能工作，直到我找到file.write（“”）行（代码的最后4行）。我得到的第一条错误消息是“因为：ORA-00911:invalid character”，其余的与之类似

这就是我认为错误所在的地方：

file.write("")
db.eachRow(sql) {
    file.append(it.MOPID + "\t" + it.EOM + "\t" + it.Mopstart + "\n")

我认为我的代码存在的问题是，有不止一个表，在编写代码时，有些东西变得非常复杂。非常感谢你的知识

尊敬的~Corpa Loom我不确定您是否首先检查了返回任何行的sql。我篡改了你的SQL，结果证明它是无效的。您现在编写sql的方式不会返回任何行，尽管它说它是有效的

预期问题：

和to_char（mopactivity.mopend，'dd-mon-yyyyy hh24:mi:'）>“2013-05-28 06:01”

在上一行中，您试图比较两个不同格式的

varchar

，这两种格式永远不会产生任何结果

下面是一个为您的sql定制的正确格式的示例。试试看。

这是您的修复Copra。上周末见到你真高兴

import groovy.sql.Sql

    'jdbc:oracle:thin:@10.10.47.193:1521:ORCL',
    'reporter', 'r3p0rt3r', 'oracle.jdbc.pool.OracleDataSource')

def sql = """

如果您没有将其写入文件，而是执行了一个println-它工作吗？好的，只是查找错误消息-它说sql语句中有一个特殊字符。我要做的第一件事是尝试db.eachRow（sql.toString（）），我的sql似乎运行顺利，甚至可以从SQuirreL导出到Excel。我忍不住想知道，在一个多表SQL调用中，然后想写入文件，在启动文件之前，如何确保选择或集中了要导出的表。write？
