Importing data from an Excel file to a SQL database is simple.
Importing data from an Excel file to a SQL database is simple.
-- Importing data from an Excel file to a SQL database is simple. Use the following statement:
/* ===================================================== ===================================== */
-- If the table to be imported already exists
Insert into Table select * from
OPENROWSET ('Microsoft. JET. OLEDB.4.0'
, 'Excel 5.0; HDR = YES; DATABASE = c: \ test.xls ', sheet1 $)
-- If you import data and generate a table
Select * into table from
OPENROWSET ('Microsoft. JET. OLEDB.4.0'
, 'Excel 5.0; HDR = YES; DATABASE = c: \ test.xls ', sheet1 $)
/* ===================================================== ===================================== */
-- If you export data from the SQL database to Excel, And the Excel file already exists, and you have created a header based on the data to be received, you can simply use it:
Insert into OPENROWSET ('Microsoft. JET. OLEDB.4.0'
, 'Excel 5.0; HDR = YES; DATABASE = c: \ test.xls ', sheet1 $)
Select * from table
-- If the Excel file does not exist, you can use BCP to import Excel-like files. Note the case sensitivity:
-- Export tables
EXEC master .. xp_mongoshell 'bcp database name. dbo. table name out "c: \ test.xls"/c-/S "server name"/U "username"-P "password "'
-- Export Query Information
EXEC master .. xp_cmdshell 'bcp "SELECT au_fname, au_lname FROM pubs .. authors order by au_lname "queryout" c: \ test.xls "/c-/S" server name "/U" username "-P" password "'
/* -- Description:
C: \ test.xls is the Excel file name for import/export.
Sheet1 $ is the worksheet name of the Excel file. You must add $ to use it normally.
--*/
-- The following is how to export a real Excel file:
If exists (select * from dbo. sysobjects where id = object_id (n' [dbo]. [p_exporttb] ') and OBJECTPROPERTY (id, n' IsProcedure') = 1)
Drop procedure [dbo]. [p_exporttb]
GO
/* -- Data export EXCEL
Export the table data to Excel, including the field name. The file is a real Excel file.
If the file does not exist, the file is automatically created.
If the table does not exist, the table is automatically created.
Only standard data types can be exported for the sake of universality.
