Suppose there is two columns in Excel, the first list is named, the second list is a queue (16-bit) and the bank account is exported to the text file, and the first 8 bits and the post-8 bits are separated.
If you want to insert the statement above, the text file must exist, and there is a row: Name, Bank Account 1, Bank Account 2 You can use the following statement to make an important note file name and directory to modify according to your actual situation.
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 a text file directly, use BCP
Declare @SQL VARCHAR (8000), @ TbName Varchar (50)
- First import the Excel table content 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 ') ...

- Delete Temporary Table EXEC ('Drop Table' @ TBNAME)
Import files into the stored procedure exported to the database with BCP:
/ * - Import export of BCP-binary files
Support Image, Text, NTEXT field import / export image is suitable for binary files; text, ntext is suitable for text data files
Note: When importing all rows that cover the condition, all the rows that meet the conditions are also available to the specified file.
