TempDB tables can be instantiated from the client or server tier. However, no table can have a foreign key column that references the primary key of a TempDB table. But TempDB tables cannot be used directly by Enterprise Portal data sets.Ī TempDB table can have a foreign key column that references the primary key of another table.

TempDB tables can be used by forms, and in X++ code that is not tied to any user interface. For more information, see Table Properties.Ĭan be used from Enterprise Portal by using.

The SaveDataPerCompany property on a TempDB table can be set to either Yes or No. Your X++ SQL code can join a TempDB table to a regular table to perform multi-row operations in a single call. The following table describes the capabilities of TempDB tables. For more information, see Temporary InMemory Tables. TempDB tables are a different type of temporary table than InMemory tables. A TempDB table is not dropped when you set its record buffer variable to null. The TableType property value can be set at AOT > Data Dictionary > Tables > MyTempDBTable > Properties > TableType.Īll types of temporary tables are automatically dropped by the system when the table variable in X++ goes out of scope. This value comes from the TableType::TempDB enum value. We call them TempDB tables because their TableType property value is TempDB. In Microsoft Dynamics AX, one type of temporary table is a TempDB table. To get the size of tables that use user defined keys instead of automatic indices (pairs() type) you need to use the function table.size() referenced above.Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012 ipairs() type of tables with numerical indices. This is the standard Lua way of getting the size of index tables i.e. Parametersįor index based tables you can get the size with the # operator: See for more info table.size table.size (t) Returns the size of a key-value table (this function has to iterate through all of the table to count all elements). The sort algorithm is not stable that is, elements considered equal by the given order may have their relative positions changed by the sort. If comp is not given, then the standard Lua operator < is used instead.

If comp is given, then it must be a function that receives two table elements, and returns true when the first is less than the second (so that not comp(a,a) will be true after the sort).

"/a", mytable ) table.sort table.sort(Table ) Sorts table elements in a given order, in-place, from Table to Table, where n is the length of the table. Saves the table mytable to the lua file mytable in your Mudlet Home Directory table. table.keys table.keys(table) return a table that is the collection of the keys in use by the table passed in Parameters index_of ( words, "greetings" )) end table.is_empty table.is_empty(table) Check if a table is devoid of any values. contains ( words, "greetings" ) then table.remove ( words, table. The function to use for determining what order to iterate the items in the table. Spairs spairs(tbl, sortFunction) Returns an iterator similar to pairs(tbl) but sorts the keys before iterating through them. Through them you can add to tables, remove values, check if a value is present in the table, check the size of a table, and more. These functions are used to manipulate tables.
