Export to DBF

If you want to export data to an already generated structure (that is, an existing) FoxPro table, you can use the following SQL statement directly


INSERT INTO OPENROWSET (' MSDASQL ',
' Driver=microsoft Visual FoxPro Driver; SOURCETYPE=DBF; Sourcedb=c:\ ',
' SELECT * from [AA]. DBF] ')
SELECT * FROM table

Description
Sourcedb=c:\ Specify the folder where the FoxPro table resides
Aa. DBF Specifies the filename of the FoxPro table.


Export to access


INSERT INTO OPENROWSET (' Microsoft.Jet.OLEDB.4.0 ',
' X:\A.mdb '; ' Admin '; ', a table) SELECT * FROM database name ... Table B


Import Access


Insert into B table Selet * FROM OPENROWSET (' Microsoft.Jet.OLEDB.4.0 '),
' X:\A.mdb '; ' Admin '; ', table A

Excel leads to txt


Want to use SELECT * into OpenDataSource (...) from OpenDataSource (...)


Implement to import an Excel file content into a text file

Suppose there are two columns in Excel, the first column is the name, and the second column is a very line account number (16-bit)
And the bank account number is exported to the text file in two parts, the first 8 digits and the latter 8 bits separately.

If you want to insert the above statement, the text file must exist, and there is one line: Name, bank account 1, Bank Account 2, and then you can use the following statement to insert, note that the file name and directory according to your actual situation to modify.


INSERT INTO
OpenDataSource (' MICROSOFT. JET. oledb.4.0 '
, ' Text; Hdr=yes;database=c:\ '
)... [Aa#txt]
--, aa#txt)
--*/
Select name, bank account 1=left (bank account, 8), Bank account 2=right (bank account, 8)
From
OpenDataSource (' MICROSOFT. JET. oledb.4.0 '
, ' Excel 5.0; Hdr=yes;imex=2;database=c:\a.xls '
--, sheet1$)
)... [sheet1$]


If you want to insert and generate text files directly, you will use BCP


DECLARE @sql varchar (8000), @tbname varchar (50)

--First import the contents of the Excel table into a global temporary table
Select @tbname = ' [# #temp ' +cast (NEWID () as varchar (40)) + '] '
, @sql = ' select name, bank account 1=left (bank account, 8), Bank account 2=right (bank account, 8)
Into ' + @tbname + ' from
OpenDataSource (' MICROSOFT. JET. oledb.4.0 '
, ' Excel 5.0; Hdr=yes;imex=2;database=c:\a.xls '
)... [sheet1$] '
EXEC (@sql)

--then use BCP to export to a text file from a global temporary table
Set @sql = ' bcp ' + @tbname + ' ' Out ' c:\aa.txt '/S ' (local) '/p '/C '
EXEC master.. xp_cmdshell @sql

--Delete temporary tables
EXEC (' drop table ' + @tbname)

Implementing stored procedures for data import/export
You can import/export an entire database/single table based on different parameters
Call Example:
--Export Call example
----Export a single table

Add:

For export with bcp, there is no field name.
To export with OPENROWSET, you need to build a table beforehand.
Import with OPENROWSET, do not support non-native data import except Access and Excel
