SYNOPSIS

Copies data between SQL Server tables.

DESCRIPTION

Copies data between SQL Server tables using SQL Bulk Copy.



The same can be achieved also doing



$sourcetable = Invoke-DbaQuery -SqlInstance instance1 ... -As DataTable



Write-DbaDbTableData -SqlInstance ... -InputObject $sourcetable



but it will force buffering the contents on the table in memory (high RAM usage for large tables).



With this function, a streaming copy will be done in the most speedy and least resource-intensive way.





PARAMETERS

-AutoCreateTable [<Switch>]

Creates the destination table if it does not already exist, based off of the "Export..." script of the source

table.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-BatchSize [<Int>]

The BatchSize for the import defaults to 5000.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-bulkCopyTimeOut [<Int>]

Value in seconds for the BulkCopy operations timeout. The default is 30 seconds.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-CheckConstraints [<Switch>]

If this switch is enabled, the SqlBulkCopy option to process check constraints will be enabled.



Per Microsoft "Check constraints while data is being inserted. By default, constraints are not checked."



Required? false

Accept wildcard characters? false



-Database [<String>]

The database to copy the table from.



Required? false

-Destination [<Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]

Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or

greater.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-DestinationDatabase [<String>]

The database to copy the table to. If not specified, it is assumed to be the same of Database



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-DestinationSqlCredential [<Pscredential>]

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).



Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory -

Integrated are all supported.

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables

advanced scripting.

Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own

try/catch.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-FireTriggers [<Switch>]

If this switch is enabled, the SqlBulkCopy option to fire insert triggers will be enabled.

Accept wildcard characters? false



-InputObject [<Microsoft.SqlServer.Management.Smo.Table[]>]

Enables piping of Table objects from Get-DbaDbTable



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-KeepIdentity [<Switch>]

If this switch is enabled, the SqlBulkCopy option to preserve source identity values will be enabled.



Per Microsoft "Preserve source identity values. When not specified, identity values are assigned by the

destination."



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-KeepNulls [<Switch>]

If this switch is enabled, the SqlBulkCopy option to preserve NULL values will be enabled.



Per Microsoft "Preserve null values in the destination table regardless of the settings for default values.

When not specified, null values are replaced by default values where applicable."



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-NoTableLock [<Switch>]

If this switch is enabled, a table lock (TABLOCK) will not be placed on the destination table. By default,

this operation will lock the destination table while running.



Required? false

Default value

Accept pipeline input? False

Accept wildcard characters? false



-NotifyAfter [<Int>]

Sets the option to show the notification after so many rows of import



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Query [<String>]

If you want to copy only a portion of a table or selected tables, specify the query.

Ensure to select all required columns. Calculated Columns or columns with default values may be excluded.

The tablename should be a full three-part name in form [Database].[Schema].

You can specify a three-part name like db.sch.tbl. If the object has special characters please wrap them in square brackets [ ]. This dbo.First.Table will try to find table named 'Table' on schema 'First' and database 'dbo'. The correct way to find table named 'First.Table' on schema 'dbo' is passing dbo.[First.Table] Required? false Position? named Default value Accept pipeline input?
