Write a quick PowerShell script to query Excel data. Use connectivity to the live data to replicate Excel data to SQL Server.
The CData ODBC Driver for Excel enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real Excel data with PowerShell.
You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating Excel data to other databases. This article shows how to replicate Excel data to SQL Server in 5 lines of code.
You can also write PowerShell code to execute create, read, update, and delete (CRUD) operations. See the examples below.
Create an ODBC Data Source for Excel
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
The ExcelFile, under the Authentication section, must be set to a valid Excel File.
Connect to Excel
The code below shows how to use the DSN to initialize the connection to Excel data in PowerShell:
$conn = New-Object System.Data.Odbc.OdbcConnection
$conn.ConnectionString = "DSN=CData Excel Source x64"
Back Up Excel Data to SQL Server
After you enable caching, you can use the code below to replicate data to SQL Server.
Set the following connection properties to configure the caching database:
CacheProvider: The name of the ADO.NET provider. This can be found in the Machine.config for your version of .NET. For example, to configure SQL Server, enter System.Data.SqlClient.
CacheConnection: The connection string of properties required to connect to the database. Below is an example for SQL Server:
Server=localhost;Database=RSB;User Id=sqltest;Password=sqltest;
The SQL query in the example can be used to refresh the entire cached table, including its schema. Any already existing cache is deleted.
$conn.Open()
# Create and execute the SQL Query
$SQL = "CACHE DROP EXISTING SELECT * FROM " + $Sheet
$cmd = New-Object System.Data.Odbc.OdbcCommand($sql,$conn)
$count = $cmd.ExecuteNonQuery()
$conn.Close()
The driver gives you complete control over the caching functionality. See the help documentation for more caching commands and usage examples. See the help documentation for steps to replicate to other databases.
Other Operations
To retrieve Excel data in PowerShell, call the Fill method of the OdbcDataAdapter method. To execute data manipulation commands, initialize the OdbcCommand object and then call ExecuteNonQuery. Below are some more examples CRUD commands to Excel through the .NET Framework Provider for ODBC:
Retrieve Excel Data
$sql="SELECT Name, Revenue from Sheet"
$da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn)
$dt= New-Object System.Data.DataTable
$da.Fill($dt)
$dt.Rows | foreach {
$dt.Columns | foreach ($col in dt{
Write-Host $1[$_]
}
}
Update Excel Data
$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Sheet SET Name='Bob' WHERE Id = @myId", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()
Insert Excel Data
$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Sheet SET Name='Bob' WHERE Id = @myId", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()
Delete Excel Data
$cmd = New-Object System.Data.Odbc.OdbcCommand("DELETE FROM Sheet WHERE Id = @myid", $conn)
$cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH")
$cmd.ExecuteNonQuery()
