subList

public static List<List<String>> subList(List<String> originalList,
 int subSize)

compareSqlStatements

public static Map<String,List<String>> compareSqlStatements(String sql1,

比较两个多行SQL语句的差异

参数:

sql1 - 第一个SQL语句 (旧版本)

sql2 - 第二个SQL语句 (新版本)

返回:

Map 包含 "added" 和 "removed" 的行列表. Key: "added" -> List 新增的行 (存在于sql2但不存在于sql1) Key: "removed" -> List 删除的行 (存在于sql1但不存在于sql2)

main

public static void main(String[] args)
