如何使用JDBC执行一组相关的SQL指令? [英] How to execute a set of related SQL instructions with JDBC?

问题描述

我正在尝试通过JDBC(它是SQL Server)执行此脚本:

I'm trying to execute this script through JDBC (it's SQL Server):

DECLARE @var VARCHAR(10)
SET @var = "test"
INSERT INTO foo (name) VALUES (@var)

这只是一个例子，在我的业务案例中，我在一个脚本中收集了大量SQL语句.

It's just an example, in my business case I have a big collection of SQL statements in one script.

我正在尝试:

final Statement stmt = connection.createStatement();
for (String sql : lines) {
  stmt.executeUpdate(sql);
}
stmt.close();

SQL Server在第二行说:

SQL Server is saying on the second line:

java.sql.SQLException: Must declare the scalar variable "@var".

好像我做错了事...

Looks like I'm doing something wrong...

推荐答案

您一次要执行一行，所以第二行当然会失败，因为它取决于第一行.为什么不立即执行所有操作呢?...

You're executing it one line at a time, so of course the second line fails as it depends on the first line. Why not execute it all at once?...
