Fix: Restore missing right-click menu options for temporal table history tables in Object Explorer

[Copilot]

Temporal table history nodes (nodeType = "HistoryTable") were only showing Refresh and Copy Object Name in the Object Explorer context menu — missing New Query, Select Top 1000, Generate Script, and Open in Copilot actions that regular Table nodes expose.

Root Cause

All affected when clauses in package.json matched only type=(Table). History table nodes report type=HistoryTable, so they fell through every menu condition except the generic ones.

Changes

• package.json — view/item/context menu entries: Added HistoryTable to the when clause regex for:

  • mssql.objectExplorerNewQuery (New Query)
  • mssql.scriptSelect (Select Top 1000)
  • mssql.sqlScriptsSubmenu (Generate Script submenu)
  • mssql.objectExplorerChatWithDatabase (Open in Copilot Chat)
  • mssql.objectExplorerChatWithDatabaseInAgentMode (Open in Copilot Agent)

• package.json — commandPalette entries: Added HistoryTable to mssql.scriptSelect, mssql.scriptCreate, and mssql.scriptDelete conditions.

mssql.editTable and mssql.tableExplorer are intentionally excluded — history tables are system-managed and read-only, consistent with SSMS behavior.

Code Changes Checklist

• New or updated unit tests added

<issue_title>[Bug]: Temporal table child tables missing right-click menu options</issue_title>
<issue_description>### Description

A SQL Server Temporal Table has a parent/current table and a child/history table. In the Explorer UI, the child table is nested below the parent. When right-clicking the child table, the only options are "Copy Object Name" and "Refresh". There are no options for "Select Top 1000", "New Query", etc. Contrast this with SSMS where the parent and child tables are treated largely the same with similar options.

This is inconvenient when trying to investigate temporal table schema and data.

Steps to Reproduce

1. Expand a temporal table
2. Right click the child table
3. Compare with parent table or SSMS options

Affected Area

• Connection dialog (SQL Server | Azure browse/Fabric browse)
• Query editor
• Query results panel
• Object Explorer
• GitHub Copilot integration
• Preview/Edit data
• Table Designer
• Schema Designer
• Schema Compare
• Local SQL Server Container provisioning
• SQL database in Fabric provisioning
• DACPAC/BACPAC export/import
• SQL Database projects
• Query Plan Visualizer
• Other (please describe below)

If you selected "Other", please describe the affected area

<agent_instructions>The type of the sub table is "HistoryTable". Your changes will largely be in package.json, but you may also need to update the commands themselves.

The missing menu items are:

• New query
• Select top 1000
• Generate Script submenu
• Open in Copilot (chat + agent)</agent_instructions>

@Benjin SSMS context menu for parent:

SSMS context menu for history table:

Looks like there should be SELECT TOP 1000 and Script Table As..., but neither have "New Query".

MSSQL parent:
