function Invoke-SQLBulkCopy { | ||
<# | ||
.SYNOPSIS | ||
Use the .NET SQLBulkCopy class to write data to SQL Server tables. | ||
.DESCRIPTION | ||
Use the .NET SQLBulkCopy class to write data to SQL Server tables. | ||
The data source is not limited to SQL Server; any data source can be used, as long as the data can be loaded to a DataTable instance or read with a IDataReader instance. | ||
.PARAMETER ServerInstance | ||
A SQL instance to run against. For default instances, only specify the computer name: "MyComputer". For named instances, use the format "ComputerName\InstanceName". | ||
.PARAMETER Database | ||
A string specifying the name of a database. | ||
.PARAMETER Credential | ||
Specifies A PSCredential for SQL Server Authentication connection to an instance of the Database Engine. If -Credential is not specified, Invoke-Sqlcmd attempts a Windows Authentication connection using the Windows account running the PowerShell session. | ||
SECURITY NOTE: If you use the -Debug switch, the connectionstring including plain text password will be sent to the debug stream. | ||
.PARAMETER ConnectionTimeout | ||
Specifies the number of seconds when Invoke-Sqlcmd2 times out if it cannot successfully connect to an instance of the Database Engine. The timeout value must be an integer between 0 and 65534. If 0 is specified, connection attempts do not time out. | ||
.PARAMETER Force | ||
If specified, skip the confirm prompt | ||
.PARAMETER BatchSize | ||
The batch size for the bulk copy operation. | ||
.PARAMETER NotifyAfter | ||
The number of rows to fire the notification event after transferring. 0 means don't notify. Notifications hit the verbose stream (use -verbose to see them) | ||
.PARAMETER ColumnMappings | ||
A hash table with the format Key = SourceColumn, Value = DestinationColumn | ||
Example, converting SourceColumn FirstName to DestinationColumn surname, and converting SourceColumn LastName to DestinationColumn givenname | ||
@{ | ||
FirstName = 'surname' | ||
LastName = 'givenname' | ||
} | ||
.PARAMETER SQLConnection | ||
An existing SQLConnection to use | ||
.EXAMPLE | ||
Invoke-SQLBulkCopy -ServerInstance $SQLInstance -Database $Database -Table $SQLTable -DataTable $DataTable -verbose -NotifyAfter 1000 -force | ||
Insert a datatable into a table. Notify via verbose every 1000 rows. Don't prompt for confirmation. | ||
.OUTPUTS | ||
None | ||
Produces no output | ||
