Want to use
SELECT * Into OpenDataSource (...) from OpenDataSource (...)
To import the contents of an Excel file into a text file
Suppose there are two columns in Excel, the first column is the name, and the second column is a row account number (16-bit)
And the bank account number is exported to a text file divided into two parts, the first 8 and the last 8 bits apart.
Kingjian:
If you want to insert the above statement, the text file must exist, and there is a line: name, bank account 1, Bank account 2
You can then insert it with the following statement
Note that the file name and directory are modified according to your actual situation.
INSERT INTO
OpenDataSource (' MICROSOFT. JET. oledb.4.0 '
, ' Text; Hdr=yes;database=c:\ '
)... [Aa#txt]

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 a text file directly, you will need to use BCP
DECLARE @sql varchar (8000), @tbname varchar (50)

Select @tbname = ' [# #temp ' +cast (NEWID () as varchar (40)) + '] '

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