很喜欢notepad++， 简单而强大

今天想利用他来正则抽取所有sql语句中的表名，SQL语句如下，以供广大人民使用

getEntityData.sql=select s.analysis_group_id,s.period_id,s.period_value_id,s.fiscal_year_nbr,s.period_start_dt,s.period_end_dt,o.CURRENCY_ID from dbo.statement s,dbo.organization o where s.statement_id= @statementId and o.ORGANIZATION_ID=s.ANALYSIS_GROUP_ID union select s1.analysis_group_id,s1.period_id,s1.period_value_id,s1.fiscal_year_nbr,s1.period_start_dt,s1.period_end_dt,o1.CURRENCY_ID from dbo.statement s1,dbo.organization o1 where s1.statement_id=@statementId and o1.ORGANIZATION_ID=s1.ANALYSIS_GROUP_ID getGLwithVequation.sql=select distinct h.account_id ,e.expression_txt,a.account_ds,e.business_txt,e1.expression_txt from dbo.FINANCIAL_ACCOUNT_HIERARCHY h,dbo.FINANCIAL_ACCOUNT a,dbo.FINANCIAL_ACCOUNT_CONDITION c, dbo.EXPRESSION e,dbo.EXPRESSION_SCOPE es,dbo.EXPRESSION e1 where a.active_ind=’Y’ and h.account_relationship_type_id=1 and h.account_id=a.account_id and c.account_id=h.account_id and c.evaluation_expression_id=e.expression_id and e.expression_scope_id=es.expression_scope_id and es.expression_cd=’VALIDATION’ and c.validation_expression_id=e1.expression_id and e.expression_id < 20000 思路： 尝试把匹配的表名放置到每一行，并且给表名前后加一个特别的标记， 然后利用Mark功能去掉unMarked的行，最后通过TextFX插件去掉重复的行

1. 将正则匹配的字符串替换变成行

2.Mark，注意要勾选 Bookmark line.

3. Search->Bookmark->Remove Unmarked Lines  去掉unmarked的行

4. 用下面正则去替换成空值：

^(.*?)$\s+?^(?=.*^\1$)

另外，也可以安装TextFX插件， 然后TextFX->TextFX Tools->Sort lines case insensitive  。注意要勾选Sort output only UNIQUE lines.

到此就可以提取到了所有正则匹配的数据。
