SQL Server stored procedure to export Select Result to CSV

问题

In my stored procedure, I want to export select result to a .CSV file. I need to write a stored procedure which selects some data from different tables and saves it to a .CSV file.

Selecting part is ready

 SELECT DISTINCT 
                  PER.NREGNUMBER_PERNUM AS [Registration Number], 
                  PER.CFAMNAME_PER AS [Family Name], 
                  PER.CGIVNAME_PER AS [Given Name], 
                  CONVERT(varchar(10), CONVERT(date, PER.DBIRTHDATE_PER, 106), 103) AS [Birth Date], 
                  PER.CGENDER_PERGEN as [Gender],
                  PHONE.MOBILE_NUMBER
        FROM      PERSON AS PER 
                  LEFT OUTER JOIN
                  PHONE ON PER.NREGNUMBER_PERNUM = PHONE.NREGNUMBER_PPHPER AND PHONE.CPRIMARY_PPH = 'Y'

The task was I had to export from database some data to .CSV at specified time. In the begining we wanted to use windows scheduler for running stp. The STP had to be able to export data. But I couldn't find a way. Instead the thing what we did was creating simple STP which brings only data . And we created batch file which calls STP and export result to .CSV file. The batch file is simple

sqlcmd -S Etibar-PC\SQLEXPRESS -d MEV_WORK -E -Q "dbo.SelectPeople" -o "MyData1.csv" -h-1 -s"," -w 700

dbo.SelectPeople is STP
Etibar-PC\SQLEXPRESS is Schema
MEV_WORK is Database name.

i have build a procedure to help you all

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

-- example exec Sys_Database_exportToCsv 'select MyEmail from 
QPCRM.dbo.Myemails','D:\test\exported.csv'

create PROCEDURE Sys_Database_exportToCsv

(
@ViewName nvarchar(50),
@exportFile nvarchar(50)
)

AS

BEGIN

SET NOCOUNT ON;

EXEC sp_configure 'show advanced options', 1;  

RECONFIGURE; 

EXEC sp_configure 'xp_cmdshell', 1;  

RECONFIGURE; 

Declare @SQL nvarchar(4000)

Set @SQL = 'Select * from ' + 'QPCRM.dbo.Myemails'

Declare @cmd nvarchar(4000)

SET @cmd = 'bcp '+CHAR(34)+@ViewName+CHAR(34)+' queryout 
'+CHAR(34)+@exportFile+CHAR(34)+' -S '+@@servername+' -c -t'+CHAR(34)+','+CHAR(34)+' -r'+CHAR(34)+'\n'+CHAR(34)+' -T'

exec master..xp_cmdshell @cmd

EXEC sp_configure 'xp_cmdshell', 0;  

RECONFIGURE; 

EXEC sp_configure 'show advanced options', 0;

To create a CSV string from you table result follow the instruction on

http://blog.sqlauthority.com/2009/11/25/sql-server-comma-separated-values-csv-from-table-column/

As far as I know there is no way to save data into a file on disk directly using TSQL. To save a file, you can create a SQL-CLR stored procedure instead of a TSQl one in which you can use regular C# code.
