################################################################################ <# .SYNOPSIS Manages key-value pairs in a SQLite database store. .DESCRIPTION Provides persistent storage for key-value pairs using SQLite. Handles both insertion of new entries and updates to existing ones. Supports optional synchronization for non-local stores. .PARAMETER StoreName The name of the store where the key-value pair will be saved. .PARAMETER KeyName The unique identifier for the value within the specified store. .PARAMETER Value The data to be stored, associated with the specified key. .PARAMETER SynchronizationKey Identifies the synchronization scope. Use "Local" for local-only storage. Defaults to "Local". Non-local values trigger store synchronization. .EXAMPLE Set-ValueByKeyInStore -StoreName "ConfigStore" -KeyName "ApiEndpoint" ` -Value "https://api.example.com" .EXAMPLE setvalue ConfigStore ApiEndpoint "https://api.example.com" #> function Set-ValueByKeyInStore { [CmdletBinding()] [Alias("setvalue")] param ( ######################################################################## [Parameter( Mandatory = $true, Position = 0, HelpMessage = "Store name for the key-value pair" )] [string]$StoreName, ######################################################################## [Parameter( Mandatory = $true, Position = 1, HelpMessage = "Name of the key to set or update" )] [string]$KeyName, ######################################################################## [Parameter( Mandatory = $false, Position = 2, HelpMessage = "Value to be stored" )] [string]$Value, ######################################################################## [Parameter( Mandatory = $false, Position = 3, HelpMessage = "Key to identify synchronization scope" )] [string]$SynchronizationKey = "Local" ######################################################################## ) begin { # construct path to sqlite database file $databaseFilePath = Expand-Path ` "$PSScriptRoot\..\..\..\..\GenXdev.Local\KeyValueStores.sqllite.db" ` -CreateDirectory Write-Verbose "Using database at: $databaseFilePath" } process { # ensure database exists if (-not (Test-Path $databaseFilePath)) { Write-Verbose "Database not found.
