CREATE TABLE "Family" (
  "Family_ID" INTEGER NOT NULL, 
  "Name" TEXT(20) NOT NULL,
);

CREATE TABLE "Babygirl" (
  "Baby_Id" INTEGER NOT NULL,
  "Family_ID" INTEGER NOT NULL,
  "Family_Name" TEXT(20) NOT NULL default......,
  "Last_Name" TEXT(20) NOT NULL,
);

我如何在Family_name用户使用Name of Family表的值后编写默认的sql ？

我的项目是maven + intellij.我在Windows系统中开发.首先我使用最新的scala libray版本2.12.2.为了获取类SQLContext等,我必须导入spark jar:

但后来有人告诉我,如果我想使用这个火花罐,我必须降低我的scala版本,所以我删除了libiray并更改为2.10 ....但是现在当我mvn_clean_install.I得到了这个:

为什么IntelliJ无法找到这些依赖？
