![]() ![]() This example gets information about processes that run on a system and writes it to a table. Write-SqlTableData -ServerInstance "MyServer\MyInstance" -DatabaseName "MyDatabase" -SchemaName "dbo" -TableName "TaskManagerDump" -Force Examples Example 1: Write information about processes to a table PS C:\> (Get-Process | Select-Object -Property Id,ProcessName,StartTime,UserProcessorTime,WorkingSet,Description) | For example, strings are mapped to NVARCHAR(MAX). The cmdlet infers the schema of the table from the data. This usage enables quick transfer of data into a database. If you specify the Force parameter, the cmdlet generate missing objects, which include the database, the table schema, and the table itself. By default, the cmdlet appends data to that table. This cmdlet can infer information such as server, database, schema, and table from its current path. You can use this cmdlet with the Windows PowerShell SQL provider. If you provide a DataSet, only the first table in the dataset is written to the database. This cmdlet accepts the following input types the follow output formats: The Write-SqlTableData cmdlet inserts data into a table of a SQL database. In this article Syntax Write-Sql Table Data $row.Writes data to a table of a SQL database. foreach($db in $databases) įull Example Code # Just the User databases The first statement in the foreach is to create this. Use a foreach loop to do this.Īs we loop through the results we need to use the “NewRow” method to assign the values. With our DataTable defined we can now loop through the SQL results and add them. Let’s add a timestamp column to include today’s date and time: $("timestamp") Loop Through The DataTable Since this is a virtual Powershell table we do not need to match the naming convention or the column names. Notice that the fields correlate directly to one of the results from the SQL query. We are changing the column names slightly but you can use the same SQL field names for the column names if you prefer. Let’s define the columns by matching them up with our SQL results. $Datatable.Columns DataTable Column Names In this example we need to create some fields or columns and define them based on our SQL results. You will see Rows, Namespace, PrimaryKey and more choices to explore. Now that the objects is created you can type the variable name ($Datatable) and use the DOT notation to display the methods available. Next we create the DataTable object: # build a "data" table The $databases variable is now loaded with our SQL result set and we need to create the DataTable, iterate through the results and load them into the Table in Powershell. $databases = invoke-Sqlcmd -Query $query -ServerInstance 'ServerName\sql1' $query = "SELECTįROM WHERE database_id > 4" For this we use the Invoke-SQLCmd command. This is a simple T-SQL query to grab the existing user databases on a SQL instance. We will create the table, columns and data-types for this DataTable and then the the results can be piped to a Format-Table or just display the results using the Out-Gridview command. ![]() In this example we are focusing on running a SQL statement and loading the results into a new DataTable. Creating a DataTable is a simple as: $Datatable = New-Object The DataTable Class is packed with Methods to work with data coming, going relationships and more. The DataTable is an extremely useful Object when working with different sources and types of data in SQL and using Powershell. ![]()
