Import an Excel file to a text file

Suppose there are two columns in Excel, the first column is name, and the second column is a very row account (16 digits)
The exported bank accounts are divided into two parts: the first eight digits and the last eight digits.

If you want to insert the statement above, the text file must exist and have one line: name, bank account 1, bank account 2
Then you can use the following statement to insert
Note that the file name and directory are modified according to your actual situation.

Insert
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 directly insert and generate a text file, you need to use BCP

Declare @ SQL varchar (8000), @ tbname varchar (50)

-- First import the Excel table content to 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)

-- Use bcp to export data from a global temporary table to a text file
Set @ SQL = 'bcp "'+ @ tbname +'" out "C:/aa.txt"/s "(local)"/P ""/C'
Exec master .. xp_mongoshell @ SQL

-- Delete a temporary table
Exec ('drop table' + @ tbname)

The stored procedure of using bcp to import and export files to the database:

/* -- BCP-Import and Export of binary files

Supports import/export of image, text, and ntext Fields
Image is suitable for binary files; text and ntext are suitable for text data files.

Note: during import, all rows meeting the conditions will be overwritten.
During export, all rows that meet the conditions will also be exported to the specified file.

This stored procedure is only implemented using BCP
