Repeatedly typing the same inspection query adds effort without adding judgment. SSMS code snippets and templates give you a reviewed starting point while leaving the final query visible before execution.
Keep Your Code Snippets in a User Folder
Store your own .snippet files in a folder you control, such as the SqlSnippets folder under your Windows Documents directory. Keep them separate from installed snippets so application updates do not become an unexpected editing exercise. A personal folder also makes review and backup straightforward without changing installation permissions.
Open Tools, Code Snippets Manager, select SQL, and inspect the Location field for an installed folder's actual path. Paths differ by SSMS version and installation. Use the displayed location when investigating existing snippets instead of assuming a hard-coded application directory. Import individual files or add your own folder through the manager.
I keep the initial library small: a column inspection, a bounded data preview, and a transaction rehearsal shell. Each has a clear purpose and conservative defaults. A huge snippet collection can become another place to search for a query you could have written faster. Reuse pays when the selected starting point is trustworthy.
Understand the XML Behind Code Snippets
A snippet file is XML with a CodeSnippet element, descriptive header, declarations, and a Code element whose language is SQL. The namespace identifies the snippet schema. CDATA keeps the SQL text readable inside the XML. Save the document with a .snippet extension, not an unnoticed .txt extension.
Literal declarations define the editable placeholders. Their IDs correspond to dollar-delimited references in the SQL body. When the snippet expands, the editor highlights fields for replacement. Those fields are text substitution, not SQL parameters or automatic identifier escaping. Review the generated statement after filling them in and before executing it.
The following Windows PowerShell blocks save the XML in your Documents folder. Expand the resulting snippets in the SQL editor before executing their SQL. The first complete example is read-only and uses schema and table names as catalog-filter values. Enter simple names without quotation characters when filling its literals. A name containing an apostrophe needs deliberate SQL string escaping in the expanded query. The snippet cannot infer that correction from its friendly label.

[System.IO.File]::WriteAllText(
(Join-Path $SnippetFolder 'InspectColumns.snippet'),
$SnippetText, [System.Text.UTF8Encoding]::new($false))Register and Insert the First Snippet
Save that XML as InspectColumns.snippet in your user folder. In Code Snippets Manager, use Add to register the folder or Import to place the individual file in the selected user collection. Select SQL as the language and confirm the title appears in the appropriate collection before trying to insert it.
In a SQL query editor, press Ctrl+K, then Ctrl+X. This is a two-step chord rather than four keys held together. Choose the collection and snippet, then fill the highlighted fields. Keyboard bindings can be customized, so the Insert Snippet menu command provides an alternative when the expected chord has been reassigned.
Confirm the editor's server and database context before running the expanded catalog query. The same table name can exist in multiple databases, and the snippet intentionally uses the current database's catalog. Reusable code snippets save typing; they do not choose the correct target database or verify your access on their own.
Add a Bounded Preview Snippet
A data preview needs a limited row request and a deliberate ordering key. This second file supplies both as editable literals. It is a starting pattern, not a universal query for every table. Replace the ordering column with an appropriate deterministic key and inspect the resulting identifiers before execution.

$SnippetText, [System.Text.UTF8Encoding]::new($false))Save it as BoundedPreview.snippet. The conservative output selects the chosen key only; add approved attributes as needed. Avoid changing the reusable default to SELECT star merely for convenience. Also remember that TOP limits returned rows, not necessarily the work needed to find them. Review the plan for unfamiliar large tables.
Add a Rehearsal Transaction Shell
The third file provides a rollback-by-default shell for testing reviewed transactional database changes. It rejects an existing transaction so the sample does not accidentally roll back unrelated work. Replace the commented placeholder with the specific operation only in an appropriate rehearsal session. A rollback shell does not reverse external side effects or every kind of administrative action.

$SnippetText, [System.Text.UTF8Encoding]::new($false))Save it as RollbackRehearsal.snippet and verify expansion before adding real work. Do not run only a selected middle fragment that leaves an open transaction. The editor can execute a selection instead of the entire script, so the safety of the surrounding text depends on what you actually submit.
Use Template Explorer for Larger Scripts
Template Explorer is useful for complete scripts with several related placeholders. Open it from the View menu, choose SQL Server templates, and organize your custom templates in a named folder. Template parameters use the form shown below, and Specify Values for Template Parameters replaces them consistently through the script.
-- Template text, replace its parameters before execution:
-- SELECT TOP (<SampleSize, int, 20>)
-- [<KeyName, sysname, OrderID>]
-- FROM [<SchemaName, sysname, dbo>].[<TableName, sysname, Orders>]
-- ORDER BY [<KeyName, sysname, OrderID>];The parameter's type field describes the placeholder; it does not convert the expanded text into a bound SQL parameter. Review quoting and names just as you do for snippets. Use Ctrl+Shift+M for the standard parameter dialog when that binding is active, and keep a pristine template separate from an incident-specific filled copy.
Review Code Snippets After Schema and Editor Changes
Keep the reusable library under regular review as the database and editor change. I test every snippet by expanding it in a fresh editor, replacing all literals, and checking the complete output. Confirm that the XML imports, the expected fields are editable, and the SQL targets the intended database. An import success only proves that the editor accepted the file structure.
Which defaults would be risky if someone executed them unchanged? Prefer read-only inspection and explicit placeholders for consequential operations. Remove stale assumptions after schema changes and review the library after SSMS upgrades. A snippet should make the familiar query easier to read, not make an old mistake easier to repeat.

A snippet is not an execution decision, it is a reusable starting point that still needs review.
