Question

我有一个包含如下数据的字符串:

'ID,MASTER_ID,DATA_SOURCE_ID,DATA_SOURCE_NAME,CHILD_COUNT,CHILD_COUNT_TEXT,PARENT_OR_CHILD,RECORD_TYPE,FULL_NAME_LNF,FULL_NAME_FNF,FIRST_NAME,LAST_NAME,PREFIX,SUFFIX,MIDDLE,TITLE,NAME_OF_ORGANIZATION,NAME_OF_BUSINESS,TYPE_OF_ENTITY,ADDRESS,CITY,STATE,PROVINCE,POSTAL_CODE,COUNTRY,POSTAL_ADDRESS_TYPE,PHONE_AREA_CODE,PHONE_NUMBER,PHONE_COUNTRY_CODE,PHONE,PHONE_TYPE,EMAIL_ADDRESS,URL,HCP_SPECIALTY,HCP_TYPE,HCP_SUBTYPE,RECIPIENT_STATUS,COVERED_RECIPIENT_FLAG,RELATIONSHIP_TO_CR,LAST_MODIFIED_BY,LAST_MODIFIED_DATE,PRIMARY_LICENSE_STATE_AR,PRIMARY_LICENSE_NUM_AR,DEA_REG_NUM_AR,NPI_NUM_AR,UPIN_AR,TAX_PAYER_ID_AR,PRIMARY_LICENSE_STATE_CR,PRIMARY_LICENSE_NUM_CR,DEA_REG_NUM_CR,NPI_NUM_CR,UPIN_CR,DEA_NUMBER,NPI,UPIN,TIN,TAX_PAYER_ID_CR,ATTRIBUTE13,ATTRIBUTE14,ATTRIBUTE15,ATTRIBUTE16,ATTRIBUTE17,ATTRIBUTE18,ATTRIBUTE19,ATTRIBUTE20,ATTRIBUTE21,ATTRIBUTE22,ATTRIBUTE23,ATTRIBUTE24,ATTRIBUTE25,ATTRIBUTE26,ATTRIBUTE27,ATTRIBUTE28,ATTRIBUTE29,ATTRIBUTE30,SOURCE_REGION_CODE,SOURCE_SYSTEM_CODE,REC_INVALID_FLAG,REVISION_FLAG,IS_ACTIVE,PROCESS_STATE,RECIPIENT_CATEGORY01,RECIPIENT_CATEGORY02,RECIPIENT_CATEGORY03,RECIPIENT_CATEGORY04,RECIPIENT_CATEGORY05,RECIPIENT_CATEGORY06,RECIPIENT_CATEGORY07,RECIPIENT_CATEGORY08,RECIPIENT_CATEGORY09,RECIPIENT_CATEGORY10,RECIPIENT_CATEGORY11,RECIPIENT_CATEGORY12,RECIPIENT_CATEGORY13,RECIPIENT_CATEGORY14,RECIPIENT_CATEGORY15,RECIPIENT_CATEGORY16,RECIPIENT_CATEGORY17,RECIPIENT_CATEGORY18,RECIPIENT_CATEGORY19,RECIPIENT_CATEGORY20,RECIPIENT_CATEGORY21,RECIPIENT_CATEGORY22,RECIPIENT_CATEGORY23,RECIPIENT_CATEGORY24,RECIPIENT_CATEGORY25,RECIPIENT_CATEGORY26,RECIPIENT_CATEGORY27,RECIPIENT_CATEGORY28,RECIPIENT_CATEGORY29,RECIPIENT_CATEGORY30,IS_PICKABLE,IS_GOLDEN,PRIMARY_LICENSE_NUM,PRIMARY_LICENSE_EFFECTIVE,PRIMARY_LICENSE_EXPIRES,TERTIARY_LICENSE_EFFECTIVE,TERTIARY_LICENSE_EXPIRES,SECONDARY_LICENSE_EFFECTIVE,SECONDARY_LICENSE_EXPIRES,SECONDARY_LICENSE_NUM,TERTIARY_LICENSE_NUM,ADDRESS2,PHONE_AREA_CODE2,PHONE_NUMBER2,PHONE_COUNTRY_CODE2,PHONE_TYPE2,TERRITORY,PRIMARY_AFFILIATION,PRIMARY_AFFILIATION_STATE,REQUEST_WF_STATE,IS_EDIT_LOCKED,SOURCE_SYSTEM_RECIPIENT_ID,CREATED_BY,CREATION_DATE,APPROVER_COMMENTS,SECONDARY_LICENSE_STATE,PRIMARY_LICENSE_STATE,NPI_DATA,STATE_DATA,DEA_DATA,RPPS,FINESS,SIREN_NUMBER,DPC'

谁能告诉我如何只找到以下值

DATA_SOURCE_ID,   
       LAST_MODIFIED_BY,
       LAST_MODIFIED_DATE,
       ATTRIBUTE13,
       ATTRIBUTE14,
       ATTRIBUTE15,
       ATTRIBUTE16,
       ATTRIBUTE17,
       ATTRIBUTE18,
       ATTRIBUTE19,
       ATTRIBUTE20,
       ATTRIBUTE21,
       ATTRIBUTE22,
       ATTRIBUTE23,
       ATTRIBUTE24,
       ATTRIBUTE25,
       ATTRIBUTE26,
       ATTRIBUTE27,
       ATTRIBUTE28,
       ATTRIBUTE29,
       ATTRIBUTE30,

然后用下面的字符串替换它们

'L.DATA_SOURCE_ID,L.LAST_MODIFIED_BY,L.LAST_MODIFIED_DATE,L.ATTRIBUTE13,L.ATTRIBUTE14,L.ATTRIBUTE15,L.ATTRIBUTE16,L.ATTRIBUTE17,L.ATTRIBUTE18,L.ATTRIBUTE19,L.ATTRIBUTE20,L.ATTRIBUTE21,L.ATTRIBUTE22,L.ATTRIBUTE23,L.ATTRIBUTE24,L.ATTRIBUTE25,L.ATTRIBUTE26,L.ATTRIBUTE27,L.ATTRIBUTE28,L.ATTRIBUTE29,L.ATTRIBUTE30,'

Answer 1

您正在寻找这个。它给你想要的结果

SELECT mycol, CONCAT('L.', mycol) AS newCol
 FROM(SELECT * FROM test WHERE mycol REGEXP 
'DATA_SOURCE_ID|LAST_MODIFIED_BY|LAST_MODIFIED_DATE|ATTRIBUTE[0-9]+') 
        as temp

解释

SELECT * FROM test WHERE mycol REGEXP 
    'DATA_SOURCE_ID|LAST_MODIFIED_BY|LAST_MODIFIED_DATE|ATTRIBUTE[0-9]+') 

这会找到所有具有 DATA_SOURCE_ID 或 LAST_MODIFIED_BY 或 LAST_MODIFIED_DATE 或 ATTRIBUTE 后跟任何数字

SELECT mycol, CONCAT('L.', mycol) AS newCol

这会将 L. 添加到子查询找到的所有行。

输出

L.DATA_SOURCE_ID,
L.LAST_MODIFIED_BY,
L.LAST_MODIFIED_DATE,
L.ATTRIBUTE13,
L.ATTRIBUTE14,
L.ATTRIBUTE15,
L.ATTRIBUTE16,
L.ATTRIBUTE17,
L.ATTRIBUTE18,
L.ATTRIBUTE19,
L.ATTRIBUTE20,
L.ATTRIBUTE21,
L.ATTRIBUTE22,
L.ATTRIBUTE23,
L.ATTRIBUTE24,
L.ATTRIBUTE25,
L.ATTRIBUTE26,
L.ATTRIBUTE27,
L.ATTRIBUTE28,
L.ATTRIBUTE29,
L.ATTRIBUTE30
