Question

在针对oracle 10g（10.2.0.1.0）运行以下SQL时遇到错误：

UPDATE fx_datumvcompgeneric AS c
   SET mp =  (SELECT p.mp
                FROM fx_propertyattrsingletscomp AS p
               WHERE c.var_container = p.id
             )
 WHERE c.mp IS NULL

错误是：ORA-00971: missing SET keyword

我们通过JDBC执行此操作，异常堆栈的顶部是：

java.sql.SQLException: ORA-00971: missing SET keyword

  oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
  oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331)
