替换字符串中的特定单词

Question

我发现很难将字符串的单词更改为固定字符串.下面是字符串的内容

 CREATE TABLE "USER1"."TEST_TAB"
   (    "O_ID" CHAR(15),
        "CREATED_DATE" DATE DEFAULT SYSDATE,
        "EVENT_ID" NUMBER,
        "LOD" BLOB,
        "TOPIC" VARCHAR2(765),
        "SCHEMA_ID" VARCHAR2(36),
        "RECORD_ID" CHAR(15),
         CONSTRAINT "R_PKCONDUIT_MESSAGE" PRIMARY KEY ("O_ID", "TOPIC", "EVENT_ID", "CREATED_DATE") ENABLE
   ) O INDEX COMPRESS 2 PCTFREE 10 INITRANS 2 MAXTRANS 255  NOLOGGING
  TABLESPACE "D01"
  STORAGE(
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
 PCTTHRESHOLD 50
 LOB ("LOD") STORE AS BASICFILE (
  DISABLE STORAGE IN ROW CHUNK 8192 RETENTION
  NOCACHE LOGGING
  STORAGE(
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT))
  PARTITION BY HASH ("O_ID")
 (PARTITION "CONDUIT_MESSAGE01"
 LOB ("LOD") STORE AS BASICFILE "LOD01"(
  TABLESPACE "D01" )
  TABLESPACE "D01" ,
 PARTITION "CONDUIT_MESSAGE02"
 LOB ("LOD") STORE AS BASICFILE "LOD02"(
  TABLESPACE "D02" )
  TABLESPACE "D02" ,
 PARTITION "CONDUIT_MESSAGE03"
 LOB ("LOD") STORE AS BASICFILE "LOD03"(
  TABLESPACE "D03" )
  TABLESPACE "D03" ,
 PARTITION "CONDUIT_MESSAGE04"
 LOB ("LOD") STORE AS BASICFILE "LOD04"(
  TABLESPACE "D04" )
  TABLESPACE "D04" ,
 PARTITION "CONDUIT_MESSAGE05"
 LOB ("LOD") STORE AS BASICFILE "LOD05"(
  TABLESPACE "D05" )
  TABLESPACE "D05" ,
 PARTITION "CONDUIT_MESSAGE06"
 LOB ("LOD") STORE AS BASICFILE "LOD06"(
  TABLESPACE "D06" )
  TABLESPACE "D06"
/

试图更改TABLESPACE"D01".... TABLESPACE"D06"到固定名称TABLESPACE"COPY_TBS"

string.replace('TABLESPACE \"D[0-9][0-9]+\"','TABLESPACE COPY_TBS')

似乎不起作用.有没有办法改变这个字符串.

Answer 1

你应该使用re.sub:

string = re.sub(r"TABLESPACE \"D[0-9]+\"", "TABLESPACE COPY_TBS", string)

string.replace 不适用于正则表达式.

演示

此外,我更改了模式以匹配表空间名称D[0-9]+,假设您希望D后跟任意数量的数字.如果你真的想限制只有两位数,那就用吧D[0-9]{2}.
