Question

试图确保在when条件下存在确切的字符串，但是现在尝试使函数在简单的剧本中运行，但似乎无法使其正常工作。还尝试过转义字符

我尝试了不同的变体，并尝试切换到“而不是”，反之亦然

my.conf

JAVA_HOME="/opt/java/hotspot/64_bit/jdk1.8.0_201/"
JAVA_HOME=/opt/java/hotspot/64_bit/jdk1.8.0_201/
JAVA_HOME=/opt/java/hotspot/64_bit/jdk1.8.0_202/
JAVA_HOME="/opt/java/hotspot/64_bit/jdk1.8.0_202/"
SUN_JAVA_HOME=/opt/java/hotspot/64_bit/jdk1.8.0_201/
SUN_JAVA_HOME="/opt/java/hotspot/64_bit/jdk1.8.0_201/"
BAE_JAVA_HOME=/opt/java/hotspot/64_bit/jdk1.8.0_201/
BAE_JAVA_HOME=/opt/java/hotspot/64_bit/jdk1.8.0_202/
BAE_JAVA_HOME="/opt/java/hotspot/64_bit/jdk1.8.0_201/"
BAE_JAVA_HOME="/opt/java/hotspot/64_bit/jdk1.8.0_202/"

剧本

---
- hosts: localhost
  tasks:
  - name: read the passwd file
    shell: cat /tmp/my.conf
    changed_when: False
    register: user_accts

  - name: set regex pattern
    set_fact:
      regex_pattern: ".*^JAVA_HOME=\"/opt/java/hotspot/64_bit/jdk1.8.0_201/\"$"
  - name: a task that only happens if the user exists
    when: user_accts.stdout |match('{{regex_pattern}}')
    debug: msg="user hillsy exists"

我想确保它找到了这个JAVA_HOME =“ / opt / java / hotspot / 64_bit / jdk1.8.0_201 /” 如果我将此行更改为 JAVA_HOME =“ / opt / java / hotspot / 64_bit / jdk1.8.0_209 /” 找不到它

我想获取确切的字符串，所以在上面的示例中我没有得到其他字符串

如果您要查找确切的字符串，则不需要正则表达式

create or replace package vendordb.p_enld0055_va is


PROCEDURE sp_group_id_update(p_batch_id NUMBER,
                           p_file_name VARCHAR2,
                           p_group_id VARCHAR2);    

end p_enld0055_va;
 /

 create or replace package body vendordb.p_enld0055_va is

 PROCEDURE sp_group_id_update(p_batch_id NUMBER,
                           p_file_name VARCHAR2,
                           p_group_id VARCHAR2) is

 v_batch_id VARCHAR2(100)     :=  p_batch_id;
 v_file_name VARCHAR2(100)    :=  p_file_name;
 v_group_id VARCHAR2(100)     :=  p_group_id;

 type t_TBL_row_ID IS TABLE OF ROWID;

 v_row_ID t_TBL_row_ID;

 cursor CUR_PPL is
 select
 h.rowid
 from VENDORDB.CLAIM_PROF_HDR h
 where batch_id = v_batch_id ;

 Begin

 open CUR_PPL;
  loop
       fetch CUR_PPL
          bulk  collect into v_row_ID
         limit 1000
        ;
    exit when v_row_ID.count()=0;

  forall i in 1 .. v_row_ID.count()

 UPDATE VENDORDB.CLAIM_PROF_HDR h
 SET group_id = CASE
                      WHEN EXISTS (select file_name from 
  nemis.file_control where batch_id = v_batch_id and file_name like 
  v_file_name) THEN v_group_id
                      ELSE NULL
                 END
  where h.rowid = v_row_ID(i);
  commit;
  end loop;
  close CUR_PPL ;

 EXCEPTION
 WHEN OTHERS THEN
 DBMS_OUTPUT.PUT_LINE('UNEXPECTED ERROR OCCURED');
  ROLLBACK;
  end;
 end p_enld0055_va;
