![]() ![]() To pan and zoom the diagram, use your touchpad, scroll bars or the mouse wheel for vertical scrolling and Shift + mouse wheel for horizontal scrolling. For more information about creating an execution plan, refer to Visualize a query plan. Execution plan is a set of steps that were used to access data in a database. If you want to share the created diagram, consider using PNG.Īlso, you can build execution plans. The UML format is an internal format developed specifically for DataGrip. using System ĭt.Columns.You can save the generated diagrams in two formats: UML and PNG. ![]() I am sure you can easily abstract this away in your case. SELECT * from will show how relatively easy it is, it just selects out the values you sent in for demo purposes. Given this SQL: CREATE TYPE MyTableType as TABLE (ID nvarchar(25),OrderNumber int)ĬREATE PROCEDURE MyTableProc MyTableType READONLY) Using Table Valued parameters is really not that complex. _Reader.Dispose() // optional needed if getting data back from proc call _Reader.GetString(0) and _Reader.GetInt32(1). IDENTITY), then fill a new Dictionary(ID, RowNumber) from OUTPUT clause to return INSERTED., INSERTED. SqlDataReader _Reader = _Command.ExecuteReader() ĭo something with _Reader: If using INSERT or MERGE in the Stored Proc, use an OR, to get data back from a SELECT or OUTPUT clause: Either send the data and move on with life: _Command.CommandType = CommandType.StoredProcedure _TVParam.Value = SendRows(M圜ollection) // method return value is streamed data ![]() _TVParam.SqlDbType = SqlDbType.Structured _TVParam.ParameterName = _TVParam.TypeName = "IDsAndOrderNumbers" //optional for CommandType.StoredProcedure SqlParameter _TVParam = new SqlParameter() SqlDataReader _Reader = null // only needed if getting data back from proc call SqlCommand _Command = new SqlCommand("ImportData", _Connection) SqlMetaData _TvpSchema = new SqlMetaData ") Private static IEnumerable SendRows(Dictionary RowData) INSERT INTO SchemaName.TableName (ID, SortOrderNumber)Ĭ# code, Part 1: Define the iterator/sender using System.Collections SQL object # 2: Use the structure - Second: Use the UDTT as an input param to an import proc.ĬREATE PROCEDURE dbo.ImportData dbo.IDsAndOrderNumbers READONLY SQL object # 1: Define the structure - First: You need a User-Defined Table TypeĬREATE TYPE dbo.IDsAndOrderNumbers AS TABLE As you can see from the code below, this setup is not overly complicated yet highly flexible as well as efficient and scalable. The only real requirement is that you need to define the structure in terms of SqlDb types and iterate through the collection, both of which are fairly trivial steps.Ī simplistic overview of the minimal structure is shown below, which is an adaptation of the answer I posted on How can I insert 10 million records in the shortest time possible?, which deals with importing data from a file and is hence slightly different as the data is not currently in memory. So, for larger sets of data there is an option to stream the contents of any custom collection. Using a DataTable is fine (not to mention quick and easy) for smaller sets of data, but for larger sets it does not scale given that it duplicates the dataset by placing it in the DataTable simply for the means of passing it to SQL Server. The accepted answer of using a TVP is generally correct, but needs some clarification based on the amount of data being passed in. ![]()
