SQL Server data conversion with Access, Excel

access|excel|server| Data | Conversion familiar to SQL Server 2000 database administrators know that its DTS can be exported for data import, in fact, we can also use Transact-SQL statements to import export operations. In Transact-SQL statements, we mainly use the OPENDATASOURCE function, the OPENROWSET function, and a detailed description of the function, please refer to the SQL online Help. You can easily implement SQL SERVER, ACCESS, and Excel data transformations using the following methods, which are described in detail:

Data import export for SQL SERVER and access

General Data Import Export:

To migrate your Access data to SQL Server using the DTS Wizard, you can use these steps:

1 on the Tools menu in SQL Server Enterprise Manager, select Data transformation

2Services (Data Transformation Services), and then select Czdimport Data (import).

3 Select Microsoft Access as the source in the Choose a Data Source dialog box and type the file name of your. mdb database (. mdb file extension) or browse for the file.

4 in the Choose a destination (select target) dialog box, select Microsoft OLE DB Prov ider for SQL server, select the database server, and then click the necessary authentication method.

5 in Specify Table copy (specify table copy) or query (query) dialog box, click Copy Tables (copy table).

6 in the Select Source Tables dialog box, click Select All (selected). Next, Finish.

Transact-SQL statements for import Export:

1. Query access data in SQL Server:

-- ======================================================

SELECT *

From OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\DB.mdb '; User id=admin; Password= ') ... Table name

2. Import access into SQL Server

-- ======================================================

Running in SQL SERVER:

SELECT *

Into newtable

From OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\DB.mdb '; User id=admin; Password= ') ... Table name

3. Insert data from SQL Server tables into an Access table

-- ======================================================

Running in SQL SERVER:

Insert into OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\DB.mdb '; User id=admin; Password= ') ... Table name

(column name 1, column name 2)

Select Column Name 1, column name 2 from SQL table

Instance:

Insert into OPENROWSET (' microsoft.jet.oledb.4.0 ',

' C:\db.mdb '; ' Admin '; ', Test)

Select Id,name from Test

INSERT into OPENROWSET (' microsoft.jet.oledb.4.0 ', ' C:\trade.mdb '; ' Admin '; ", table name)

SELECT *

From Sqltablename

Second, SQL SERVER and Excel data Import Export

1. Query Excel data in SQL Server:

-- ======================================================

SELECT *

From OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\Book1.xls '; User id=admin; password=; Extended properties=excel 5.0 ') ... [sheet1$]

The following is an example of a query that queries an EXCEL spreadsheet by using the OLE DB provider for Jet.

SELECT *
From OpenDataSource (' microsoft.jet.oledb.4.0 ',
' Data source= ' C:\Finance\account.xls '; User id=admin; password=; Extended properties=excel 5.0 ') ... xactions

2. Import Excel data into SQL Server:

-- ======================================================

SELECT * into newtable

From OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\Book1.xls '; User id=admin; password=; Extended properties=excel 5.0 ') ... [sheet1$]

Instance:

SELECT * into newtable

From OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\Finance\account.xls '; User id=admin; password=; Extended properties=excel 5.0 ') ... xactions

3, the SQL Server query to the data into an Excel file

-- ======================================================

T-SQL code:

EXEC Master.. xp_cmdshell ' bcp library name. dbo. Table name out c:\Temp.xls-c-q-s "servername"-U "sa"-P "" "

Parameter: s is SQL Server name; u is user; p is a password

Description: You can also export a variety of formats such as text files

Instance: EXEC Master ... xp_cmdshell ' bcp saletesttmp.dbo.CusAccount out c:\temp1.xls-c-q-s ' pmserver '-u ' sa '-P ' sa '

EXEC Master.. xp_cmdshell ' bcp ' select au_fname, au_lname from pubs. Authors ORDER BY au_lname "Queryout c:\ authors.xls-c-sservername-usa-ppassword"

Applying ADO to export Excel file code in VB6:

Dim cn as New ADODB. Connection

Cn.open "Driver={sql Server}; Server=websvr;database=webmis; Uid=sa; wd=123; "

Cn.execute "Master. xp_cmdshell ' bcp ' select col1, col2 from library name. dbo. Table name "Queryout E:\DT.xls-c-sservername-usa-ppassword '"

4. Insert data into Excel in SQL Server:

-- ======================================================

Insert into OpenDataSource (' microsoft.jet.oledb.4.0 ',

' Data source= ' C:\Temp.xls '; User id=admin; password=; Extended properties=excel 5.0 ') ... table1 (a1,a2,a3) VALUES (1,2,3)

T-SQL code:

INSERT into

OpenDataSource (' Microsoft.Jet.OLEDB.4.0 ',

' Extended properties=excel 8.0;data source=c:\training\inventur.xls ') ... [filiale1$]

(Bestand, Produkt) VALUES (' Test ')

Summary: Using the above statements, we can easily transform the data in SQL SERVER, Access, and Excel spreadsheet software, providing great convenience for us!
