Spooling sql to a CSV when data contains commas - sql

I'm trying to spool a sql query to a CSV file using a command prompt, however one column of data I'm returning contains comma's in the data and is causing the data to go into the next column. Is there a way to get around this? Ideally, I would like this particular column returned in the middle of query, not at the end.
I'm currently using the following commands:
set termout off;
set colsep ',';
set underline off;
set feedback off;
set pagesize 0;
set linesize 1500;
set trimspool on;
I know the set colsep ',' command is the issue however, haven't been able to figure out what to replace it with. Does anyone have any recommendations?
Also, right before my sql query, I'm using a select statement to pull the header information. Select 'a, b, c' from dual; Not sure if that makes a difference in the answer or not.


Two potential answers. Neither of them perfect. If you have commas in some of the results, but no pipes (|), you could switch to a pipe-delimited with
set colsep '|'
Most software that can read csv will do just fine with that format.
If that doesn't work for you, you can realize that to treat commas within a column, you'll need to wrap every data item in quotes:
"data 1","data 2","data,with,commas"
To do this, each separator will need to be "," so you can
set colsep '","'
This will not have quotation marks at the beginning and ending of each line, so you can then wrap every line in quotes with sed:
sed 's/^[^$]*$/"&"/'


You can modify your select query like
select REPLACE(column_name, ',',' ') column name from table_name
This will replace comma value from your column data with space.


You can modify your query that returns the result set by surrounding that column with double-quotes. Assuming b is the culprit:
select a
, '"' || trim(B) || '"' as b
, c
from your_table;
Proper syntax depends on your RDBMS version of course.

Database query issue - trying to insert a query in column [duplicate]

I am trying to insert some text data into a table in SQL Server 9.
The text includes a single quote '.
How do I escape that?
I tried using two single quotes, but it threw me some errors.
eg. insert into my_table values('hi, my name''s tim.');

Single quotes are escaped by doubling them up, just as you've shown us in your example. The following SQL illustrates this functionality. I tested it on SQL Server 2008:
DECLARE #my_table TABLE (
[value] VARCHAR(200)
)
INSERT INTO #my_table VALUES ('hi, my name''s tim.')
SELECT * FROM #my_table
Results
value
==================
hi, my name's tim.

If escaping your single quote with another single quote isn't working for you (like it didn't for one of my recent REPLACE() queries), you can use SET QUOTED_IDENTIFIER OFF before your query, then SET QUOTED_IDENTIFIER ON after your query.
For example
SET QUOTED_IDENTIFIER OFF;
UPDATE TABLE SET NAME = REPLACE(NAME, "'S", "S");
SET QUOTED_IDENTIFIER ON;
-- set OFF then ON again

How about:
insert into my_table values('hi, my name' + char(39) + 's tim.')

Many of us know that the Popular Method of Escaping Single Quotes is by Doubling them up easily like below.
PRINT 'It''s me, Arul.';
we are going to look on some other alternate ways of escaping the single quotes.
1. UNICODE Characters
39 is the UNICODE character of Single Quote. So we can use it like below.
PRINT 'Hi,it'+CHAR(39)+'s Arul.';
PRINT 'Helo,it'+NCHAR(39)+'s Arul.';
2. QUOTED_IDENTIFIER
Another simple and best alternate solution is to use QUOTED_IDENTIFIER.
When QUOTED_IDENTIFIER is set to OFF, the strings can be enclosed in double quotes.
In this scenario, we don’t need to escape single quotes.
So,this way would be very helpful while using lot of string values with single quotes.
It will be very much helpful while using so many lines of INSERT/UPDATE scripts where column values having single quotes.
SET QUOTED_IDENTIFIER OFF;
PRINT "It's Arul."
SET QUOTED_IDENTIFIER ON;
CONCLUSION
The above mentioned methods are applicable to both AZURE and On Premises .

2 ways to work around this:
for ' you can simply double it in the string, e.g.
select 'I''m happpy' -- will get: I'm happy
For any charactor you are not sure of: in sql server you can get any char's unicode by select unicode(':') (you keep the number)
So this case you can also select 'I'+nchar(39)+'m happpy'

The doubling up of the quote should have worked, so it's peculiar that it didn't work for you; however, an alternative is using double quote characters, instead of single ones, around the string. I.e.,
insert into my_table values("hi, my name's tim.");

Also another thing to be careful of is whether or not it is really stored as a classic ASCII ' (ASCII 27) or Unicode 2019 (which looks similar, but not the same). This isn't a big deal on inserts, but it can mean the world on selects and updates. If it's the unicode value then escaping the ' in a WHERE clause (e.g where blah = 'Workers''s Comp') will return like the value you are searching for isn't there if the ' in "Worker's Comp" is actually the unicode value.If your client application supports free-key, as well as copy and paste based input, it could be Unicode in some rows, and ASCII in others!
A simple way to confirm this is by doing some kind of open ended query that will bring back the value you are searching for, and then copy and paste that into notepad++ or some other unicode supporting editor. The differing appearance between the ascii value and the unicode one should be obvious to the eyes, but if you lean towards the anal, it will show up as 27 (ascii) or 92 (unicode) in a hex editor.

The following syntax will escape you ONLY ONE quotation mark:
SELECT ''''
The result will be a single quote. Might be very helpful for creating dynamic SQL :).

Double quotes option helped me
SET QUOTED_IDENTIFIER OFF;

SET QUOTED_IDENTIFIER ON;

DECLARE #singleQuote CHAR
SET #singleQuote = CHAR(39)
insert into my_table values('hi, my name'+ #singleQuote +'s tim.')

Just insert a ' before anything to be inserted. It will be like a escape character in sqlServer
Example:
When you have a field as, I'm fine.
you can do:
UPDATE my_table SET row ='I''m fine.';

I had the same problem, but mine was not based of static data in the SQL code itself, but from values in the data.
This code lists all the columns names and data types in my database:
SELECT DISTINCT QUOTENAME(COLUMN_NAME),DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS
But some column names actually have a single-quote embedded in the name of the column!, such as ...
[MyTable].[LEOS'DATACOLUMN]
To process these, I had to use the REPLACE function along with the suggested QUOTED_IDENTIFIER setting. Otherwise it would be a syntax error, when the column is used in a dynamic SQL.
SET QUOTED_IDENTIFIER OFF;
SET #sql = 'SELECT DISTINCT ''' + #TableName + ''',''' + REPLACE(#ColumnName,"'","''") + ...etc
SET QUOTED_IDENTIFIER ON;

The STRING_ESCAPE funtion can be used on newer versions of SQL Server

This should work: use a back slash and put a double quote
