The function supports limiting the number of returned records and provides verbose output for tracking query execution. .PARAMETER ConnectionString The connection string to connect to the SQLite database. This parameter is mutually exclusive with DatabaseFilePath. .PARAMETER DatabaseFilePath The file path to the SQLite database file. This parameter is mutually exclusive with ConnectionString. .PARAMETER ViewName The name of the view from which to retrieve data. .PARAMETER Count The maximum number of records to return. Use -1 to return all records. Defaults to 100 if not specified. .EXAMPLE Get-SQLiteViewData -DatabaseFilePath "C:\MyDb.sqlite" ` -ViewName "CustomerView" ` -Count 50 .EXAMPLE Get-SQLiteViewData "C:\MyDb.sqlite" "CustomerView" #> function Get-SQLiteViewData { [CmdletBinding(DefaultParameterSetName = 'DatabaseFilePath')] param ( ######################################################################## [Parameter( Position = 0, Mandatory = $true, ParameterSetName = 'ConnectionString', HelpMessage = 'The connection string to the SQLite database.' )] [ValidateNotNullOrEmpty()] [string]$ConnectionString, ######################################################################## [Parameter( Position = 0, Mandatory = $true, ParameterSetName = 'DatabaseFilePath', HelpMessage = 'The path to the SQLite database file.' )] [ValidateNotNullOrEmpty()] [Alias('dbpath', 'indexpath')] [string]$DatabaseFilePath, ######################################################################## [Parameter( Position = 1, Mandatory = $true, HelpMessage = 'The name of the view to query.' )] [ValidateNotNullOrEmpty()] [string]$ViewName, ######################################################################## [Parameter( Position = 2, Mandatory = $false, HelpMessage = 'Number of records to return. -1 for all records.' )] [ValidateRange(-1, [int]::MaxValue)] [int]$Count = 100 ) begin { Microsoft.PowerShell.Utility\Write-Verbose "Starting Get-SQLiteViewData for view: $ViewName" } process { # construct query with optional record limit $query = if ($Count -eq -1) { "SELECT * FROM $ViewName" } else { "SELECT * FROM $ViewName LIMIT $Count" } Microsoft.PowerShell.Utility\Write-Verbose "Executing query: $query" # prepare parameters for Invoke-SQLiteQuery $PSBoundParameters['Queries'] = $query # execute query and return results GenXdev.Data\Invoke-SQLiteQuery @PSBoundParameters } end { Microsoft.PowerShell.Utility\Write-Verbose "Completed querying view: $ViewName" } } |
