问题
I am trying to execute a compound statement of following type in DB2 command line processor
BEGIN ATOMIC
UPDATE schema.tablename set column1 = xyz where condition = somecondition;
UPDATE schema.tablename2 set column2 = abc where condition = somecondition
END
But I am receiving following error
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

I am not sure if this is supported in db2 sql command line processor. The requirement is to execute three queries in an atomic fashion but not in a stored procedure. Please guide if there is any other alternative too.
回答1:
You will need to define a non-default statement terminator character, otherwise the command line processor cannot distinguish semicolons within a compound statement and the one after the compound statement.
So, you would invoke it as db2 -td@, setting the statement terminator to "@", and your statement will look like:
BEGIN ATOMIC
UPDATE schema.tablename set column1 = xyz where condition = somecondition;
UPDATE schema.tablename2 set column2 = abc where condition = somecondition;
END@
