SQL Server bcp utility export/write incomplete data - sql

I am using SQL Server bcp utility to export data in csv format from a table.
I've noticed that sometimes the exported data is incomplete, I mean the bcp process exit without errors but the resulting csv file shows incomplete data at the end.
For example this is the bcp command and log of a recent export:
bcp "SELECT IdSap, CodSap, replace(replace(convert(nvarchar(max), Dati_XML), char(13), ''), char(10), '') as Dati_XML FROM MYDB.dbo.MyTable WHERE DataAggiornamento > '2019-06-07'" queryout "C:\temp\bcp_output.csv" -c -t 0x1f -U "myuser" -P "mypassword" -S "10.180.188.53"
As you can see there are no errors. The output file shows 100885 rows. The problem here is that the query should return 292887 rows, not 100884. It's like the bcp process has not finished to properly import/write data before exit.
Does anyone know why is this happening and any possible fix?

Is It possible to create BCP without mentioning input file name?

BULK INSERT NECCOI_DB.dbo.ALL_Stores
FROM 'C:\TestingforAutomation\AllStores.csv'
WITH
(
FIELDTERMINATOR=',',
ROWTERMINATOR='\n',
FIRSTROW=2
)
My bat file is like this:
bcp NECCOI_DB.dbo.ALL_Stores in C:\TestingforAutomation\AllStores.csv -Uvm -PMadhu#9515 -SBLLT-5CD124JQHQ -c -F2 -t ","
TIMEOUT /T 60
It is working fine without any issues ,but this script have to work without mentioning csv file name means with any csv file it should work...
so i have changed my script to this:
bcp NECCOI_DB.dbo.ALL_Stores in C:\TestingforAutomation\*.csv -Uvm -PMadhu#9515 -SBLLT-5CD124JQHQ -c -F2 -t ","
TIMEOUT /T 60
It's giving error like this:
SQLState = S1000, NativeError = 0 Error = [Microsoft][ODBC Driver 17
for SQL Server]Unable to open BCP host data-file
can anyone guide me to fix this ?thanks in advance
There is no way to do this within the BCP command.
To bulk copy many files, you'll need to write code to cycle through the list of files you want loaded and build a new bcp or bulk insert statement for each file to be loaded.
Neither the BCP utility nor the BULK INSERT t-sql command can accept wildcards.

SQL Server :query for exporting to file

I'm trying to learn the basics of sql programming, I am working with SQL Server 2014. I have managed to import a file into a table with the command:
BULK INSERT Db.dbo.Co2_table
FROM 'd:\dataset_co2.txt'
with
(
FIRSTROW =2,
ROWTERMINATOR ='\n'
)
GO
I would like to do the dual operation, that is exporting the content of a table to a file. I have tried:
SELECT *
INTO OUTFILE 'C:\datadump\sqldbdump.txt"
FROM dbo.alarms_2_2014
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n';
bcp Db.dbo.Co2_table out "C:\users\ws5.en-cre\desktop\prova.txt" -T –c
sqlcmd -S . -d Db -E -s, -W -Q "SELECT * FROM dbo.Co2_table" > ExcelTest.csv
But none of these seem to work (I get error messages). Any idea?
I suspect you are running those commands from Management Studio. You should use console for this command.This works for me. Also check if you have permissions on that folder.
bcp "select * from Db.dbo.Co2_table" queryout C:\users\ws5.en-cre\desktop\prova.txt -c -T
or
bcp Db.dbo.Co2_table out C:\users\ws5.en-cre\desktop\prova.txt -c -T
Also you have suspicious symbol in c parameter -T –c. It is not a regular dash -.
Thank you for you answers and suggestions, and apologies for my lack of precision and my late reply (in this case I missed the notifications from stackoverflow).
Regarding the question on whether I use mstudio or console, what I do is clicking on “new query” from mstudio, write the code and press execute. So I guess the answer is that I use mstudio.
If I try:
bcp "select * from Db.dbo.Co2_table" queryout
C:\users\ws5.en-cre\desktop\prova.txt -c –T
it says
Msg 102, Level 15, State 1, Line 1 Incorrect syntax near 'queryout'.
I guess in this case one of the problem is that the quotes are missing, but even adding them doesn’t solve the problem.
I am looking for a solution that can be implemented as a script. I am familiar with excel vba macros, I would like to implement something like that.
Thanks,
Alex

SQL Server BCP Empty File

I'm trying to use bcp to query out a comma-separated-value file but each time I get an empty file.
Here's my bcp command:
bcp "SELECT * FROM ##OutAK " QUERYOUT D:\Outbound\raw\li14090413.raw -c -T -t -S DB1
I have verified that ##OutAK is NOT empty because select count (*) from ##OutAK is not 0. When open file using HEX editor, I see the following:
0D 0A
I found the problem. It seems BCP is "allergic" with NULL. So, I just put ISNULL() to all the null-able fields and the output file is back to normal now.

My bcp hangs after creating an empty file

I am trying to drop a file into a directory on the local machine (same machine running SQL Instance). The content of the table I am trying to drop out is in xml format.
ie. table=xmlOutFiles, fieldName = xmlContent; fieldName contains essentially varchar(max) data that is to become the xml file we need.
When the bcp command is executed it seems to create the file in the #dest location, size = 0 bytes and then the process running from within SMSS just sits there waiting for something!
I cannot do anything with that empty file, like delete it, unless I use task manager to kill the process "bcp.exe".
I have tried multiple combinations of the bcp flags, etc.
Running the bcp command from a system prompt, replacing the "#vars" seems to work but I really need it to be part of my SQL Trigger script and function.
Assistance appreciated!!!!
Select #dest = (Select filename from xmlOutfiles)
Select #cmd = 'bcp "Select xmlContent from ProcureToPay.dbo.XmlOutFiles" queryout '+#dest+' -x -w -T -S' + ##servername
Exec xp_cmdshell #cmd
I have tried executing with -T and -Uusername -Ppassword parameters, etc.
This command works from the DOS prompt:
bcp "Select xmlContent from Procure.To.Pay.dbo.XmlOutFiles" queryout c:\temp\test.xml -x -w -T S<myservernameHere>

Unable to open BCP host data-file

Below is an example of the BCP Statement.
I'm not accustomed to using BCP so your help and candor is greatly appreciated
I am using it with a format file as well.
If I execute from CMD prompt it works fine but from SQL I get the error.
The BCP statement is all on one line and the SQL Server Agent is running as Local System.
The SQL server, and script are on the same system.
I ran exec master..xp_fixeddrives
C,45589
E,423686
I've tried output to C and E with the same result
EXEC xp_cmdshell 'bcp "Select FILENAME, POLICYNUMBER, INSURED_DRAWER_100, POLICY_INFORMATION, DOCUMENTTYPE, DOCUMENTDATE, POLICYYEAR FROM data.dbo.max" queryout "E:\Storage\Export\Data\max.idx" -fmax-c.fmt -SSERVERNAME -T
Here is the format file rmax-c.fmt
10.0
7
1 SQLCHAR 0 255 "$#Y#$" 1 FILENAME
2 SQLCHAR 0 40 "" 2 POLICYNUMBER
3 SQLCHAR 0 40 "" 3 INSURED_DRAWER_100
4 SQLCHAR 0 40 "" 4 POLICY_INFORMATION
5 SQLCHAR 0 40 "" 5 DOCUMENTTYPE
6 SQLCHAR 0 40 "" 6 DOCUMENTDATE
7 SQLCHAR 0 8 "\r\n" 7 POLICYYEAR
Due to formating in this post the last column of the format file is cut off but reads SQL_Latin1_General_CP1_CI_AS for each column other that documentdate.
Does the output path exist? BCP does not create the folder before trying to create the file.
Try this before your BCP call:
EXEC xp_cmdshell 'MKDIR "E:\Storage\Export\Data\"'
First, rule out an xp_cmdshell issue by doing a simple 'dir c:*.*';
Check out my blog on using BCP to export files.
I had problems on my system in which I could not find the path to BCP.EXE.
Either change the PATH variable of hard code it.
Example below works with Adventure Works.
-- BCP - Export query, pipe delimited format, trusted security, character format
DECLARE #bcp_cmd4 VARCHAR(1000);
DECLARE #exe_path4 VARCHAR(200) =
' cd C:\Program Files\Microsoft SQL Server\100\Tools\Binn\ & ';
SET #bcp_cmd4 = #exe_path4 +
' BCP.EXE "SELECT FirstName, LastName FROM AdventureWorks2008R2.Sales.vSalesPerson" queryout ' +
' "C:\TEST\PEOPLE.TXT" -T -c -q -t0x7c -r\n';
PRINT #bcp_cmd4;
EXEC master..xp_cmdshell #bcp_cmd4;
GO
Before changing the path to \110\ for SQL Server 2012 and the name of the database to [AdventureWorks2012], I received the following error.
After making the changes, the code works fine from SSMS. The service is running under NT AUTHORITY\Local Service. The SQL Server Agent is disabled. The output file was created.
Please check, the file might be opened in another application or program.
If it is the case, bcp.exe cannot overwrite the existing file contents.
In my case, I solved The problem in the following way:
my command was :
bcp "select Top 1000 * from abc.dbo.abcd" queryout FileNameWithDirectory -c -t "|" -r "0x0a" -S 192.111.1.111 -U xx -P xxxxx
My FileNameWithDirectory was too long. like "D:\project-abc\R&D\abc-608\FilesNeeded\FilesNeeded\DataFiles\abc.csv".
I change into a simpler directory like : "D:\abc.csv"
Problem solved.
So I guess the problem occurred due to file name exceeding. thus the file was not found.
If it works from the command line but not from the SQL Agent, I think it is an authentication issue.
The SQL Server Agent is running under a account. Make sure that the account has the ability to read the format file and generate the output file.
Also, make sure the account has the ability to execute the xp_cmdshell stored procedure.
Write back with your progress ...
I received this after I shared my output folder, even when there were no files open.
I created a new, unshared folder for output and all was fine.
(might help someone ;-))
In my case this fix was simply running in administrator mode.
This error can be due to insufficient write permissions to the target folder.
This is a common issue, since the user writing the query might have access to a folder, but the SQL Server Agent or logged-in server account which actually invokes bcp.exe may not.
Destination path has to already exist (except for file name).
Remove no_output from your command, if you use one offcourse
SET #sql = 'BCP ....'
EXEC master..xp_cmdshell #sql , no_output
EXEC master..xp_cmdshell #sql
In case anyone else runs into the same problem: I had ...lesPerson" queryout' rather than ...lesPerson" queryout '
If your code is writing the data file, and then reading it with BCP, make sure that you CLOSE THE DATA FILE before trying to read it!
Failure to do so gives: 'Unable to open host data-file'.
Python example:
# Management of temporary bulk insert file.
def openBulkInsertFile(self) :
self.bulkInsertFile = open('c:/tmp/bulkInsertContent.txt', 'w', newline='')
self.csvWriter = csv.writer(self.bulkInsertFile)
def closeBulkInsertFile(self) :
self.bulkInsertFile.close()
When using a Job in SQL the user that uses the SQL express server is the current user logged, you should give write permission to that user in the folder where the Batch writes the output.
This happens usually only with bcp, when using type commands the ownership goes to the computer(Administrator) and the command runs with out problem.
So if you have a long command in your job just look for the bcp parts.
