Question

在 Databricks 中使用合并语句时出现以下错误：

 MERGE INTO t1
 USING
  t2
 ON
  t1.[c1] = t2.[c1]
 AND
  t1.[c2] <> t2.[c2]
 WHEN MATCHED THEN UPDATE
 SET   t1.[c1] = t2.[c2]

错误：

SQL 语句出错：ParseException: extraneous input

你能帮忙吗？

Answer 1

MERGE database.schema.tablename as t1 
USING <the Query you want to run or the database.schema.tablename>  as t2 
ON (t1.[c1] = t2.[c1] AND t1.[c2] != t2.[c2])
WHEN MATCHED THEN UPDATE SET t1.[c1] = t2.[c2]
