废话不多说了,直接给大家贴代码了,具体代码如下所示:
create or replace procedure proc_test is --description:删除字段中的指定字符(回车chr(13)、换行chr(10)) --by lichao --date:2016-03-01 colname varchar(20); --列名 cnt number; --包含换行符的列的行数 v_sql varchar(2000); --动态sql变量 begin --读取表中的列 for col in (select column_name from user_tab_columns where table_name = 'temp') loop colname := col.column_name; --替换换行符chr(10) v_sql := 'select count(1) from temp where instr(' || colname || ',chr(10))>0 '; execute immediate v_sql into cnt; if cnt > 0 then v_sql := 'update temp set ' || colname || '=trim(replace(' || colname || ',chr(10),''''))' || 'where instr(' || colname || ',chr(10))>0 '; execute immediate v_sql; commit; end if; --替换回车符chr(13) v_sql := 'select count(1) from temp where instr(' || colname || ',chr(13))>0 '; execute immediate v_sql into cnt; if cnt > 0 then v_sql := 'update temp set ' || colname || '=trim(replace(' || colname || ',chr(13),''''))' || 'where instr(' || colname || ',chr(13))>0 '; execute immediate v_sql; commit; end if; --替换'|' chr(124) 为'*' chr(42) v_sql := 'select count(1) from temp where instr(' || colname || ',chr(124))>0 '; execute immediate v_sql into cnt; if cnt > 0 then v_sql := 'update temp set ' || colname || '=replace(' || colname || ',chr(124),chr(42))' || 'where instr(' || colname || ',chr(124))>0 '; execute immediate v_sql; commit; end if; end loop; end proc_test; /
以上所述是www.887551.com给大家介绍的oracle删除字段中的空格、回车及指定字符的实例代码,希望对大家有所帮助
