Question

我需要将一个表从一个Oracle模式复制到另一个，可以通过在schema_one中运行以下查询来完成此操作-

create table EMPLOYEES unrecoverable as select * from schema_two.EMPLOYEES;

当使用命令行或sql developer运行时有效。

但是挑战在于使用ant脚本执行此操作。

我的蚂蚁目标如下

<target name="create.tables">
        <echo message="creating tables... " />
        <sql driver="${db.driver}"  
             url="${db.url}"
             userid="${db.username}"
             password="${db.password}"
             onerror="abort"
             keepformat="yes"
             encoding="UTF-8"
            >
            <transaction>
                create table EMPLOYEES unrecoverable as select * from schema_two.EMPLOYEES;

            </transaction>
            <classpath>
                <path refid="database.common.classpath"/>
            </classpath>
        </sql>
    </target>

其中为schema_one定义了db.driver，db.url，db.username和db.password。运行它会引发如下错误
