If you want to return values from multiple columns, you can use the following syntax: OUTPUT inserted.column1, inserted.column2... In this tutorial, you have learned how to use another form of the SQL Server INSERT statement to insert multiple rows into a table using one INSERT statement. Tables in Lua are used to store multiple values. For example, the different minigames or 'disasters' in a ROBLOX place. Inside of tables are keys and values. A key is like a variable, and it holds a value. Multitable inserts were introduced in Oracle 9i to allow a single INSERT INTO .. SELECT statement to conditionally, or unconditionally, insert into multiple tables. This statement reduces table scans and PL/SQL code necessary for performing multiple conditional inserts compared to previous versions. Multitable inserts were introduced in Oracle 9i to allow a single INSERT INTO .. SELECT statement to conditionally, or unconditionally, insert into multiple tables. This statement reduces table scans and PL/SQL code necessary for performing multiple conditional inserts compared to previous versions. My question is how (or if) you can insert two values into a lua table. I got a function that returns (a variable number of values) function a(x, y) return x, y end and another function that inserts that points into a table, function b(x, y) table.insert(myTable, x, y) end Lua allows multiple assignment, where a list of values is assigned to a list of variables in one step. Both lists have their elements separated by commas. For instance, in the assignment a, b = 10, 2*x the variable a gets the value 10 and b gets 2*x. In a multiple assignment, Lua first evaluates all values and only then executes the assignments. "Indexing" and Sorting Tables; Introduction A Lua table is a group of key<=>value pairs. Think hashes in Perl and Ruby or Dictionaries in Python. But Lua is built from the ground up to be fast and efficient with its tables. Lookup is quick. So unlike Perl, Python and Ruby, with Lua it's efficient to use a table as an array. May 04, 2012 · Re: How to print the content of Table/ If you use some form of linter to check for inadvertent global assignments, _G can be the way to explicitly assign a global. Of course, if you also wrap your globals table in metatable logic to catch assignments, then you need to do rawset( _G, "var", value ). Apr 23, 2017 · Issue With Updating Data When Multiple Nested Tables With Keys Exist in Same Table - posted in Lua Language: The app I am currently developing is very data intensive, so I am trying to use nested tables and nested tables with key values to organize data. The issue I am having arises after I insert tables of data with key values into an existing table, and then try to update data assigned to ... table.insert table.insert(table, [pos,] value) Inserts element value at position pos in table, shifting up other elements to open space, if necessary. The default value for pos is n+1, where n is the length of the table, so that a call table.insert(t,x) inserts x at the end of table t. See also: table.remove Parameters. table: May 04, 2012 · Re: How to print the content of Table/ If you use some form of linter to check for inadvertent global assignments, _G can be the way to explicitly assign a global.

Higher calling custom turkey callsTables are the only data structure in Lua, but they are more flexible than the data structures in many other languages. They are also called dictionaries (because they make values corresponding to indices, as the definitions in a dictionary correspond to the terms), associative arrays (because they associate values to indices, thus making them be arrays of values that are associated to indices ... My question is how (or if) you can insert two values into a lua table. I got a function that returns (a variable number of values) function a(x, y) return x, y end and another function that inserts that points into a table, function b(x, y) table.insert(myTable, x, y) end Tables are the only "container" type in Lua. They are associative arrays (), which means they store a set of key/value pairs. In a Key/Value pair you can store a value under a key and then later retrieve the value using that key. Creating tables. Tables are created using table constructors, which are defined using curly brackets, e.g. { } . To define an empty table we can do the following. Apr 11, 2014 · How to sort a table on 2 values? - posted in Lua Language: Hi, Im trying to sort a table alphabetically on 2 values, but so far no luck. The table should be sorted on category and within a certain category range the name field should also be sorted. So all category bread should be on top and within this category all name values should also be sorted alphabetically. local food = { {cat... As you can see in the above examples, assignments for multiples variables follows a variable_list and value_list format. In the above example local d, f = 5,10 we have d and f in variable_list and 5 and 10 in values list. Value assigning in Lua takes place like first variable in the variable_list with first value in the value_list and so on. Aug 20, 2014 · Lua tables cannot store nil values. Lua uses nil to remove table entries instead. That is, assigning nil to a table entry will remove that entry from the table. 5.1 – Multiple Results An unconventional, but quite convenient feature of Lua is that functions may return multiple results. Several predefined functions in Lua return multiple values. An example is the string.find function, which locates a pattern in a string. table.insert table.insert(table, [pos,] value) Inserts element value at position pos in table, shifting up other elements to open space, if necessary. The default value for pos is n+1, where n is the length of the table, so that a call table.insert(t,x) inserts x at the end of table t. See also: table.remove Parameters. table: table.insert was 7x slower than regular access. This is true, because table.insert requires a table lookup and a function call. However, the benchmark examples were poor. Two of the examples weren't actually inserts, they were just smashing the array with no regard for existing content. Script Name Inserting Multiple Rows Using a Single Statement Description This example creates three tables and them uses different INSERT statements to insert data into these tables. Multiple rows are inserted into a table using the INSERT ALL statement and by using the inserting the results of the select query. table.insert was 7x slower than regular access. This is true, because table.insert requires a table lookup and a function call. However, the benchmark examples were poor. Two of the examples weren't actually inserts, they were just smashing the array with no regard for existing content. Tables are called objects and they are neither values nor variables. Lua uses a constructor expression {} to create an empty table. It is to be known that there is no fixed relationship between a variable that holds reference of table and the table itself. LuaMongo is a Lua library that wraps the MongoDB C++ API. Currently it has been tested with legacy-1.1.0 version of this driver. This mongo-cxx-driver release has been included at external folder, you can download it by executing: Certain values in Lua have strict immutability, such as strings, numbers, and booleans (as well as functions barring upvalues and environments). Lua tables are mutable, but strict immutability can be simulated to some extent (bar rawset) via metamethods, as shown in ReadOnlyTables. Userdata can provide stronger enforcement. Tables are called objects and they are neither values nor variables. Lua uses a constructor expression {} to create an empty table. It is to be known that there is no fixed relationship between a variable that holds reference of table and the table itself. Inserts the value at (optional) position 'pos', renumbering existing elements if necessary to make room. Thus the new element becomes the one with index 'pos'. If called with 2 arguments, the value is inserted at n+1, that is, the end of the table. The Lua authors recommend using the idiom "#t + 1" to insert to the end of a table nowadays. The table.insert function inserts an element in a given position of an array, moving up other elements to open space. Moreover, insert increments the size of the array (using setn ). For instance, if a is the array {10, 20, 30} , after the call table.insert (a, 1, 15) a will be {15, 10, 20, 30} . Lua table functions; Lua table functions These are the functions in the "table" table. Tables are collections of key/value pairs, where both the key and the value can be any Lua data type, except nil. Tables are indexed by the key, so if you know the key you can quickly retrieve the value. Lua Lanes is a Lua extension library providing the possibility to run multiple Lua states in parallel. It is intended to be used for optimizing performance on multicore CPU's and to study ways to make Lua programs naturally parallel to begin with. LUA commands and variables list for use in Domoticz This page is created to give an overview of all the possible commands and variables in Lua that can be used in Domoticz.
