如何在存储过程SQL Server中的BCP SQL查询中转义双引号

Question

The following is my stored procedure code:

Alter PROCEDURE [dbo].[ConvertToFile]

    @TempFileName varchar(8000)
AS
BEGIN
    SET NOCOUNT OFF;

    DECLARE @bcpFileCmd varchar(8000)


SET @bcpFileCmd= 'bcp "SELECT id,full_Name,message from NotesTable " queryout '+@TempFileName+' -t, -c -T'

    EXEC master..xp_cmdshell @bcpFileCmd

END

BCP dumps all the data from NotesTable in file. But I need to enclose the message results with double quotes. The datatype for message field is text. I'm not able to append it in select query in BCP.

Answer 1

You will need to concatenate double quotes to the beginning and end of your message results, and escape both the single quotes and double quotes:

SET @bcpFileCmd= 'bcp "SELECT id, full_Name, ''""'' + message + ''""'' from NotesTable " queryout '+@TempFileName+' -t, -c -T'

If you need to retain the column name, you should also alias it like so (might not be necessary if you're just outputting to a file):

SET @bcpFileCmd= 'bcp "SELECT id, full_Name, ''""'' + message + ''""'' ''message'' from NotesTable " queryout '+@TempFileName+' -t, -c -T'
