trying to export the pl/sql script exctract to excel file which is currently extracting the data and putting it in text file

Question

I have a PL/SQL script which generates a text file currently, but I need to generate excel file from the script. I have currently have pl/sql code like below,

BEGIN  
  --column headers  
  DBMS_OUTPUT.PUT_LINE(‘column name header 1 | column name header 2 | 
  column name header 3 |………..| column name header n’);  
END; /  
  --extract 
  (SELECT UNIQUE temptable.columnname1 || '|' ||  
  temptable.columnname2 || '|' ||                
  ‘columnname3’ || '|' ||               
  ………………                
  temptable.columnnamen '|' 
  FROM   temptable 
  WHERE  temptable.OUTPUT_INDICATOR = 'extract ready'); 

I have tried renaming the destination file name with .csv extension but all the data is getting copied to a single cell in an excel. Could anyone tell me how we modify the above code to extract data to excel file? Thanks.

Answer 1

使用像提取行这样的分隔符来构建标题行，但是所有分隔符都使用逗号。

Answer 2

In cvs you should use separator, that is recognized by your excel for your locale (eg for US it is comma (,) character, in other countries it could be semicolon(;))

Below is your example with comma separated values

BEGIN  
  --column headers  
  DBMS_OUTPUT.PUT_LINE(‘column name header 1 , column name header 2 , 
  column name header 3 ,……….., column name header n’);  
END; /  
  --extract 
  (SELECT UNIQUE temptable.columnname1 || ',' ||  
  temptable.columnname2 || ',' ||                
  ‘columnname3’ || ',' ||               
  ………………                
  temptable.columnnamen ',' 
  FROM   temptable 
  WHERE  temptable.OUTPUT_INDICATOR = 'extract ready'); 

Answer 3

Use comma , for column separator and \\r\\n for line separator:

BEGIN  
  --column headers  
  DBMS_OUTPUT.PUT_LINE(‘column name header 1 , column name header 2 , 
  column name header 3 ,……….., column name header n’ || '\r\n');  
END; /  
  --extract 
  (SELECT UNIQUE temptable.columnname1 || ',' ||  
  temptable.columnname2 || ',' ||                
  ‘columnname3’ || ',' ||               
  ………………                
  temptable.columnnamen || '\r\n' 
  FROM   temptable 
  WHERE  temptable.OUTPUT_INDICATOR = 'extract ready');
