java - 续行 Spring SQL ScriptUtils(使用 H2)

Question

我有以下 SQL 脚本 (initDB.sql)

CREATE TABLE  FFShareHistorical  (  ID int NOT NULL AUTO_INCREMENT,
                                    PX_LAST  Double DEFAULT NULL, 
                                    PX_OPEN  Double DEFAULT NULL, 
                                    PX_HIGH  Double DEFAULT NULL, 
                                    PX_LOW  Double DEFAULT NULL, 
                                    PRIMARY KEY (ID))

并希望使用 Spring 的 ScriptUtils (4.1.4.RELEASE) 来执行它，即

Resource rc = new ClassPathResource("initDB.sql");
ScriptUtils.executeSqlScript(dataSource.getConnection(), rc);

问题在于，换行符似乎被解释为 SQL 语句的终止，即错误堆栈跟踪看起来像这样

所以问题是，如何将 ScriptUtils 与多行 SQL 脚本一起使用？特别是我正在寻找某种可以添加到脚本中的“行继续”字符，或者一种告诉 Spring 的 ScriptUtils 删除所有换行符的方法。

Answer 1

事实证明，使用多行语句是没有问题的。但是，如果语句未以“;”结尾，则 ScriptUtils 将退回到使用“\n”作为分隔符。所以在这种情况下，只需使用“;”终止脚本。即

CREATE TABLE  FFShareHistorical  (  ID int NOT NULL AUTO_INCREMENT,
                                    PX_LAST  Double DEFAULT NULL, 
                                    PX_OPEN  Double DEFAULT NULL, 
                                    PX_HIGH  Double DEFAULT NULL, 
                                    PX_LOW  Double DEFAULT NULL, 
                                    PRIMARY KEY (ID));

会完成这项工作。
