############################################################################### <# .SYNOPSIS Retrieves a list of all available key-value store names from the database. .DESCRIPTION Queries the SQLite database to get unique store names based on the provided synchronization key. The function handles database initialization if needed and performs synchronization for non-local scopes. Returns store names that are not marked as deleted and match the specified synchronization scope. .PARAMETER SynchronizationKey Key to identify synchronization scope. Use '%' for all stores, 'Local' for local stores only. Synchronization occurs for non-local scopes. Supports SQL LIKE pattern matching for flexible store filtering. .PARAMETER DatabasePath Directory path for preferences database files. When specified, overrides the default database location for storing key-value store configurations. .PARAMETER SessionOnly Use alternative settings stored in session for Data preferences like Language, Database paths, etc. When enabled, retrieves settings from session variables instead of persistent storage. .PARAMETER ClearSession Clear the session setting (Global variable) before retrieving. Forces a fresh retrieval of settings by clearing any cached session data before processing. .PARAMETER SkipSession Dont use alternative settings stored in session for Data preferences like Language, Database paths, etc. Forces retrieval from persistent storage, bypassing any session-cached settings. .EXAMPLE Get-KeyValueStoreNames -SynchronizationKey "Local" -DatabasePath "C:\Data" .EXAMPLE getstorenames "%" #> ############################################################################### function Get-KeyValueStoreNames { [CmdletBinding()] [System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseSingularNouns", "")] [Alias("getstorenames")] param( ############################################################################### [Parameter( Mandatory = $false, Position = 0, HelpMessage = "Key to identify synchronization scope, defaults to all" )] [string] $SynchronizationKey = "%", ############################################################################### [Parameter( Mandatory = $false, HelpMessage = "Database path for key-value store data files" )] [string] $DatabasePath, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = "Use alternative settings stored in session for Data preferences like Language, Database paths, etc" )] [switch] $SessionOnly, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = "Clear the session setting (Global variable) before retrieving" )] [switch] $ClearSession, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = "Dont use alternative settings stored in session for Data preferences like Language, Database paths, etc" )] [Alias("FromPreferences")] [switch] $SkipSession ############################################################################### ) begin { # use provided database path or default to local app data if ([string]::IsNullOrWhiteSpace($DatabasePath)) { $databaseFilePath = GenXdev.FileSystem\Expand-Path ` ("$($ENV:LOCALAPPDATA)\GenXdev.PowerShell\" + "KeyValueStores.sqllite.db") ` -CreateDirectory } else { $databaseFilePath = GenXdev.FileSystem\Expand-Path $DatabasePath ` -CreateDirectory } # output verbose message for database file path Microsoft.PowerShell.Utility\Write-Verbose ( "Using database at: $databaseFilePath" ) } process { # check if database file exists and create if needed if (-not (Microsoft.PowerShell.Management\Test-Path $databaseFilePath)) { # output verbose information about database initialization Microsoft.PowerShell.Utility\Write-Verbose ( "Database not found, initializing..." ) # copy identical parameter values for Initialize-KeyValueStores $initParams = GenXdev.Helpers\Copy-IdenticalParamValues ` -BoundParameters $PSBoundParameters ` -FunctionName "GenXdev.Data\Initialize-KeyValueStores" ` -DefaultValues (Microsoft.PowerShell.Utility\Get-Variable ` -Scope Local ` -ErrorAction SilentlyContinue) # initialize the key value stores database GenXdev.Data\Initialize-KeyValueStores @initParams } # perform synchronization for non-local stores if ($SynchronizationKey -ne "Local") { # output verbose information about synchronization Microsoft.PowerShell.Utility\Write-Verbose ( "Synchronizing non-local store: $SynchronizationKey" ) # copy identical parameter values for Sync-KeyValueStore $syncParams = GenXdev.Helpers\Copy-IdenticalParamValues ` -BoundParameters $PSBoundParameters ` -FunctionName "GenXdev.Data\Sync-KeyValueStore" ` -DefaultValues (Microsoft.PowerShell.Utility\Get-Variable ` -Scope Local ` -ErrorAction SilentlyContinue) # assign specific parameters for synchronization $syncParams.SynchronizationKey = $SynchronizationKey # synchronize the key value store with remote sources GenXdev.Data\Sync-KeyValueStore @syncParams } # construct sql query to get unique store names $sqlQuery = @" SELECT DISTINCT storeName FROM KeyValueStore WHERE synchronizationKey LIKE @syncKey AND deletedDate IS NULL; "@ # create parameters hashtable for the sql query $params = @{ 'syncKey' = $SynchronizationKey } # output verbose information about the query parameters Microsoft.PowerShell.Utility\Write-Verbose ( "Querying stores with sync key: $SynchronizationKey" ) # execute the sql query and extract store names from results GenXdev.Data\Invoke-SQLiteQuery ` -DatabaseFilePath $databaseFilePath ` -Queries $sqlQuery ` -SqlParameters $params | Microsoft.PowerShell.Core\ForEach-Object storeName } end { } } ############################################################################### |
