It is very easy to import data from the DBASE file to the SQL database. Use the following statement directly:
/* ===================================================== ===================================== */
-- If the table to be imported already exists
Insert into Table select * from
OpenRowSet ('Microsoft. Jet. oledb.4.0'
, 'Dbase5.0; database = C:/', 'select * from [test. DBF]')
-- If you import data and generate a table
Select * into table from
OpenRowSet ('Microsoft. Jet. oledb.4.0'
, 'Dbase5.0; database = C:/', 'select * from [test. DBF]')
/* ===================================================== ===================================== */
-- If you export data from the SQL database to dBase, and if the DBASE file already exists, you can simply use it:
Insert
OpenRowSet ('Microsoft. Jet. oledb.4.0'
, 'Dbase5.0; database = C:/', 'select * from [test. DBF]')
Select * from table
/* -- Description:
Database = C:/is the directory where DBF Files are stored.
'Select * from [test. DBF] test. DBF indicates the DBF file name.
--*/
-- If the DBASE file does not exist, you need to use the following stored procedure.
/* -- Data export DBASE
Export The data in the table to DBASE. If the file does not exist, the file is automatically created.
Only standard data types can be exported for the sake of universality.
