Question

我正在尝试在DB2命令行处理器

中执行以下类型的复合语句

BEGIN ATOMIC
UPDATE schema.tablename set column1 = xyz where condition = somecondition;
UPDATE schema.tablename2 set column2 = abc where condition = somecondition
END

但我收到以下错误

BEGIN ATOMIC
UPDATE schema.tablename set column1 = xyz where condition = somecondition
DB21034E  The command was processed as an SQL statement because it was not a 
valid Command Line Processor command.  During SQL processing it returned:
SQL0104N  An unexpected token "END-OF-STATEMENT" was found following "where condition = somecondition". 
Expected tokens may include:  "<delim_semicolon>".  LINE 
NUMBER=2.  SQLSTATE=42601

UPDATE schema.tablename2 set column2 = abc where condition = somecondition END

我不确定db2 sql命令行处理器是否支持此功能。要求是以原子方式执行三个查询，而不是在存储过程中执行。如果还有其他选择，请指导。

您需要定义非默认语句终止符，否则命令行处理器无法区分复合语句中的分号和复合语句后的分号。

因此，您可以将其作为db2 -td@调用，将语句终止符设置为“@”，您的语句将如下所示：

BEGIN ATOMIC
 UPDATE schema.tablename set column1 = xyz where condition = somecondition;
 UPDATE schema.tablename2 set column2 = abc where condition = somecondition;
END@
