Question

需要使用shell脚本在csv文件中提取以下查询数据和标题。

以下是查询。

SELECT SourceIdentifier,SourceFileName,ProfitCentre2,PlantCode,
tax_retur ReturnPeriod,document_number DocumentNumber,TO_CHAR(invoice_generation_date,'YYYY-MM-DD')
Docume,Original,customer_name CustomerName,NVL(sns_pos,new_state_code)POS,PortCode,NEW_HSN_CODE HSNorSAC,(SGSATE+UTGSATE) Stat,(SGS+UT)StateUT,Userde FROM arbor.INV_REPO_FINA WHERE UPPER(document_type)='INV' AND UPPER(backout_flag)='VALID' AND new_gst_id_new IS NOT NULL AND new_charges<>0 AND taxable_adj=0
UNION
SELECT SourceIdentifier,SourceFileName,ProfitCentre2,PlantCode,
tax_retur ReturnPeriod,document_number DocumentNumber,TO_CHAR(invoice_generation_date,'YYYY-MM-DD')
Docume,Original,customer_name CustomerName,NVL(sns_pos,new_state_code)POS,PortCode, NEW_HSN_CODE HSNorSAC,(SGSATE+UTGSATE) Stat,(SGS+UTG)StateUT,Userde FROM arbor.INV_REPO_FINA WHERE UPPER(document_type)='INV' AND UPPER(backout_flag)='VALID' AND new_gst_id_new IS NOT NULL AND new_charges<>0 AND  taxable_adj<>0

如果使用shell脚本获取数据的方法正确且脚本正确，请告诉我。

#!/bin/bash
file="output.csv"
sqlplus -s username/password@Oracle_SID << EOF
SPOOL $file

select 'SourceIdentifier','SourceFileName','ProfitCentre2','PlantCode',
'tax_retur ReturnPeriod','document_number DocumentNumber','TO_CHAR(invoice_generation_date,'YYYY-MM-DD') Docume','Original','customer_name CustomerName','NVL(sns_pos,new_state_code)POS','PortCode','NEW_HSN_CODE HSNorSAC','(SGSATE+UTGSATE) Stat','(SGS+UT)StateUT','Userde' from dual
Union all
select 'TO_CHAR(SourceIdentifier)','TO_CHAR(SourceFileName)','TO_CHAR(ProfitCentre2)','TO_CHAR(PlantCode)',
'TO_CHAR(tax_retur ReturnPeriod)','TO_CHAR(document_number DocumentNumber)','TO_CHAR(invoice_generation_date,'YYYY-MM-DD')
Docume','TO_CHAR(Original)','TO_CHAR(customer_name CustomerName)','TO_CHAR(NVL(sns_pos,new_state_code)POS)','TO_CHAR(PortCode)','TO_CHAR(NEW_HSN_CODE HSNorSAC)','TO_CHAR((SGSATE+UTGSATE) Stat)','TO_CHAR((SGS+UT)StateUT)','TO_CHAR(Userde)' from
(SELECT SourceIdentifier,SourceFileName,ProfitCentre2,PlantCode,
tax_retur ReturnPeriod,document_number DocumentNumber,TO_CHAR(invoice_generation_date,'YYYY-MM-DD')
Docume,Original,customer_name CustomerName,NVL(sns_pos,new_state_code)POS,PortCode,NEW_HSN_CODE HSNorSAC,(SGSATE+UTGSATE) Stat,(SGS+UT)StateUT,Userde FROM arbor.INV_REPO_FINA WHERE UPPER(document_type)='INV' AND UPPER(backout_flag)='VALID' AND new_gst_id_new IS NOT NULL AND new_charges<>0 AND taxable_adj=0
UNION
SELECT SourceIdentifier,SourceFileName,ProfitCentre2,PlantCode,
tax_retur ReturnPeriod,document_number DocumentNumber,TO_CHAR(invoice_generation_date,'YYYY-MM-DD')
Docume,Original,customer_name CustomerName,NVL(sns_pos,new_state_code)POS,PortCode, NEW_HSN_CODE HSNorSAC,(SGSATE+UTGSATE) Stat,(SGS+UTG)StateUT,Userde FROM arbor.INV_REPO_FINA WHERE UPPER(document_type)='INV' AND UPPER(backout_flag)='VALID' AND new_gst_id_new IS NOT NULL AND new_charges<>0 AND  taxable_adj<>0)

SPOOL OFF
EXIT
EOF

Answer 1

简而言之：在select语句的末尾缺少。

一些未经请求的建议：

我认为假脱机会在你的文件中添加额外的东西（至少是一些新行），重定向更好，第一行不是与数据库相关的：

echo "SourceIdentifier;SourceFileName;ProfitCentre2..." > $file

我建议在select查询中生成csv格式，以后会更加头痛（你可以逃到那里）：

$query = "select SourceIdentifier || ';' || SourceFileName || ';' || ProfitCentre2 ... ;"

所以查询数据库（我认为资本-S是正确的）以及记录的格式化（也许你也想格式化你的列）：

sqlplus -S username/password@Oracle_SID >> $file << EOF
set linesize 32767 pagesize 0 heading off
$query
EOF

Answer 2

对我来说，这是可行的，但是在第一个查询和第二个查询之前有一个空行。使用awk命令删除空行

#!/bin/bash

FILE="A.csv"
$ORACLE_HOME/bin/sqlplus -s username/password@Oracle_SID<<EOF
SET PAGESIZE 50000 COLSEP "," LINESIZE 20000 FEEDBACK OFF HEADING off
SPOOL $FILE

select 'TYPE_OF_CALL_V','SWITCH_CALL_TYPE_V','RECORD_TYPE_V','TARF_TYPE_V' from dual;
SELECT TYPE_OF_CALL_V,SWITCH_CALL_TYPE_V,RECORD_TYPE_V,TARF_TYPE_V FROM TABLE;

SPOOL OFF
EXIT
EOF

awk 'NF > 0' $FILE  > out.txt
mv out.txt $FILE
