oracle 存储过程里面判断字符串是否包含汉字

select lengthb('长度6a'),length('长度6a') from dual;

lengthb('长度6a')=8   length('长度6a')=4

一般我们那asci 码里面的下滑线来判断是否有汉字(来源于网络)

select asciistr(l.company_short_name),l.company_short_name,
--INSTR(asciistr(prod_name),'\', 1, 1),
substr(asciistr(l.company_short_name),1,INSTR(asciistr(l.company_short_name),'\', 1, 1)-1),
substr(l.company_short_name,length(substr(asciistr(l.company_short_name),1,INSTR(asciistr(l.company_short_name),'\', 1, 1)-1))+1) 
from fnd_companies_vl l where asciistr(l.company_short_name) like '%\%' and instr(l.company_short_name, '\') <= 0 and l.company_id=1104123 ;

最后写法

   SELECT COUNT(1) 
                INTO v_place_num
                FROM pur_lines_all  l
               WHERE  (trim(l.production_location) IS NULL OR 
                       (ASCIISTR(trim(l.production_location)) NOT like '%\%') OR
                       (ASCIISTR(trim(l.production_location)) like '%\%' AND lengthb(trim(l.production_location))<6 )      
               )  AND l.pur_header_id= p_pur_header_id;
         IF(v_place_num>0) THEN
              RAISE e_place_null_err;
         END IF;
