SQL Bulk Insert with FIRSTROW parameter skips the following line
You can use the below snippet
BULK INSERT TextData
FROM 'E:\filefromabove.txt'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = '|', --CSV field delimiter
ROWTERMINATOR = '\n', --Use to shift the control to next row
ERRORFILE = 'E:\ErrorRows.csv',
TABLOCK
)
I don't think you can skip rows in a different format with BULK INSERT
/BCP
.
When I run this:
TRUNCATE TABLE so1029384
BULK INSERT so1029384
FROM 'C:\Data\test\so1029384.txt'
WITH
(
--FIRSTROW = 2,
FIELDTERMINATOR= '|',
ROWTERMINATOR = '\n'
)
SELECT * FROM so1029384
I get:
col1 col2 col3
-------------------------------------------------- -------------------------------------------------- --------------------------------------------------
***A NICE HEADER HERE***
0000001234 SSNV 00013893-03JUN09
0000005678 ABCD 00013893-03JUN09
0000009112 0000 00013893-03JUN09
0000009112 0000 00013893-03JUN09
It looks like it requires the '|' even in the header data, because it reads up to that into the first column - swallowing up a newline into the first column. Obviously if you include a field terminator parameter, it expects that every row MUST have one.
You could strip the row with a pre-processing step. Another possibility is to select only complete rows, then process them (exluding the header). Or use a tool which can handle this, like SSIS.
Maybe check that the header has the same line-ending as the actual data rows (as specified in ROWTERMINATOR
)?
Update: from MSDN:
The FIRSTROW attribute is not intended to skip column headers. Skipping headers is not supported by the BULK INSERT statement. When skipping rows, the SQL Server Database Engine looks only at the field terminators, and does not validate the data in the fields of skipped rows.
I found it easiest to just read the entire line into one column then parse out the data using XML.
IF (OBJECT_ID('tempdb..#data') IS NOT NULL) DROP TABLE #data
CREATE TABLE #data (data VARCHAR(MAX))
BULK INSERT #data FROM 'E:\filefromabove.txt' WITH (FIRSTROW = 2, ROWTERMINATOR = '\n')
IF (OBJECT_ID('tempdb..#dataXml') IS NOT NULL) DROP TABLE #dataXml
CREATE TABLE #dataXml (ID INT NOT NULL IDENTITY(1,1) PRIMARY KEY CLUSTERED, data XML)
INSERT #dataXml (data)
SELECT CAST('<r><d>' + REPLACE(data, '|', '</d><d>') + '</d></r>' AS XML)
FROM #data
SELECT d.data.value('(/r//d)[1]', 'varchar(max)') AS col1,
d.data.value('(/r//d)[2]', 'varchar(max)') AS col2,
d.data.value('(/r//d)[3]', 'varchar(max)') AS col3
FROM #dataXml d
