我试图将当前数据库迁移到使用liquibase，但我不明白如何将以下内容翻译成liquibase可以使用的内容。
--liquibase formatted sql
--changeset usr:33 splitStatements:false dbms:oracle failOnError:true
create trigger some_trigger_id before insert
on table1 for each row
declare
seq_val number;
begin
if :new.myid is null then
select seq_myseq.nextval
into :new.myid
from dual;
else
begin
select seq_myseq.currval
into myid
from dual;
exception
when others then
raise_application_error(-20000, 'Illegal!! ...');
end;
if :new.myid > seq_val then
raise_application_error(-20000, 'Illegal!! ...');
end if;
end if;
end;
/
我已经尝试将此代码放在一个单独的文件中，并将其包含在<sqlFile>中，但它失败了。
"Encountered the symbol end of file when when expecting one of the following ;"
当我检查oracle时，会创建一个触发器，但代码被剪切掉，看起来像这样：
create or replace trigger some_trigger_id before insert
on table1 for each row
declare
seq_val number
代码已被切断为;，就好像忽略了属性splitStatements一样，如果我替换也没关系;与其他一些符号我得到相同的错误???
更新：这是我得到的确切错误。

解决方案： 解决方案是expicitly state endDelimiter \ n;
答案 0 :(得分：8)
使用自定义endDelimiter（默认为分号，因此liquibase正在尝试将您的代码拆分为不正确的部分）。
<changeSet id="1" author="me">
<sql endDelimiter="/">
create trigger some_trigger_id before insert
on table1 for each row
declare
seq_val number;
begin
if :new.myid is null then
select seq_myseq.nextval
into :new.myid
from dual;
else
begin
select seq_myseq.currval
into myid
from dual;
exception
when others then
raise_application_error(-20000, 'Illegal!! ...');
end;
if :new.myid > seq_val then
raise_application_error(-20000, 'Illegal!! ...');
end if;
end if;
end;
/
</sql>
</changeSet>

请查看此页面http://www.liquibase.org/documentation/sql_format.html以获取SQL格式的更改日志。
您需要确保拥有changeset标头，并确保设置splitStatements：false

更简单的DB-Trigger解决方案：
CREATE OR REPLACE TRIGGER <trigger-name> BEFORE INSERT ON <table-name> FOR EACH ROW
BEGIN
IF (:new.<column-name> IS NULL) THEN
:new.<column-name> := <sequence-name>.nextval;
END IF;
END;
