Like --disable-column-names option, do we have an option to get the sql query result in text file without having the extra symbols or characters?

for example

mysql -u username -ppassword  --disable-column-names --execute "select rules from test">out.txt

i used above to get the result .but in my test table contains below rules

    ---------------------------------------------------------------------

    rules

    ---------------------------------------------------------------------

    select no from tabl1

    select name from tabl2 innerjoin select name from tabl3

    select id from tabl6

    select card from tabl3

    --------------------------------------------------------------------

here is script i used which already mentioned above

mysql -u username -ppassword  --disable-column-names --execute "select rules from test">out.txt

when i used above query i get result like

    select no/n from tabl1

    select name/n from tabl2/n innerjoin/n select name/n from tabl3

    select id/n from tabl6

    select card/n from tabl3

is that any way to avoid this problem..i dont want special charcter like'/n ' in my text file?

Export MySQL Query Results to a File using Command Line

I performed this and I didn't get the /n characters so I'm not sure what's up with that. Perhaps the actual query results that are returned is the text content of the select statements and those /n characters are part of that content. I mention this because you say your results are the select statements with those characters.

Another solution you could use is SELECT INTO OUTFILE with a syntax such as . . .

• 
  

  select no INTO OUTFILE 'C:/Folder/Path/out.txt' from tabl1

  
  
  
  
  
  1. 
     

     With this you could execute this logic at the mysql command line as such:

     
     
     

     
     

     mysql -u username -ppassword --execute "select no INTO OUTFILE 'C:/Folder/Path/out.txt' from tabl1"
     
     

     
     

     
     
  
  
  2. 
     

     Otherwise you could put the logic into a stored procedure and accept the full file path as the first parameter passed to it at run time and execute it from the mysql command line that way.

     
     
     

     
     

     mysql -u username -ppassword --execute "CALL StoredProcName('C:/Folder/Path/out.txt')"
     
     

     
     

     
     
  
  
  
  

Note: For the full folder path that you specify which MySQL will utilize, be sure to use either a single forward slash (/) or else you double backslashes (\) which separate folders and the file because the single backslash () is a MySQL escape character.

  SELECT INTO OUTFILE
  
  

  
  

  Description

  
  
  

  SELECT ... INTO OUTFILE writes the resulting rows to a file, and
  allows the use of column and row terminators to specify a particular
  output format. The default is to terminate fields with tabs (t) and
  lines with newlines (n).

  
  
  

  The file must not exist. It cannot be overwritten. A user needs the
  FILE privilege to run this statement. Also, MariaDB needs permission
  to write files in the specified location. If the secure_file_priv
  system variable is set to a non-empty directory name, the file can
  only be written to that directory.

  
  
  

  The CHARACTER SET clause specifies the character set in which the
  results are to be written. Without the clause, no conversion takes
  place (the binary character set). In this case, if there are multiple
  character sets, the output will contain these too, and may not easily
  be able to be reloaded.
