Streams table data between SQL Server instances using high-performance bulk copy operations.
Copies data between SQL Server tables using SQL Bulk Copy for maximum performance and minimal memory usage.
Unlike Invoke-DbaQuery and Write-DbaDbTableData which buffer entire table contents in memory, this function streams data directly from source to destination.
This approach prevents memory exhaustion when copying large tables and provides the fastest data transfer method available.
Supports copying between different servers, databases, and schemas while preserving data integrity options like identity values, constraints, and triggers.
Can automatically create destination tables based on source table structure, making it ideal for data migration, ETL processes, and table replication tasks.

| Default Value |
Target SQL Server instance where table data will be copied to. Accepts one or more SQL Server instances.
Specify this when copying data to a different server than the source, or when doing cross-instance data transfers.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Alternative credentials for authenticating to the destination instance. Required when your current Windows credentials don't have access to the target server.
Use this for cross-domain scenarios, SQL authentication, or when the destination requires different security context than the source.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Source database containing the table or view to copy data from. Required when not using pipeline input.
Must exist on the source instance and your account must have read permissions on the specified objects.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Target database where copied data will be inserted. Defaults to the same database name as the source.
Use this when copying data to a different database name on the destination instance or for cross-database copies within the same server.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Source table name to copy data from. Accepts 2-part ([schema].[table]) or 3-part ([database].[schema].[table]) names.

| Default Value |
Custom SQL SELECT query to use as the data source instead of copying the entire table or view. Supports 3 or 4-part object names.
Use this when you need to filter rows, join multiple tables, or transform data during the copy operation. Still requires specifying a Table or View parameter for metadata purposes.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Automatically creates the destination table if it doesn't exist, using the same structure as the source table.
Essential for initial data migrations or when copying to new environments where destination tables haven't been created yet.
| Alias | |
| Required | False |

Use this when data integrity validation is more important than copy speed, particularly when copying from untrusted sources.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Enables INSERT triggers to fire during bulk copy operations. By default, triggers are bypassed for performance.
Use this when you need audit trails, logging, or other trigger-based business logic to execute during the data copy.
| Alias | |

| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | 0 |
Creates new tables using the destination database's default filegroup instead of matching the source table's filegroup name.
Use this when the destination database has different filegroup configurations or when you want all copied tables in the PRIMARY filegroup.

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