Table

Description

A class that represents a table structure.

A Table contains methods and properties associated with manipulating table data in FlexSim. A Table may be one of the following:

  1. A Tree Table: This is a table whose data is defined in the tree structure. This consists of a root node with one or more subnodes, each representing a row in the table. Subnodes of each row represent cells in the table.
  2. A Bundle Table: This is a table whose data is defined by a bundle node. This consists of a node in the tree that contains bundle data.
  3. A Query Result Table: This is a read-only in-memory table that contains the result of a call to Table.query().

Bundle and tree tables can be stored anywhere in the model tree. Often they are stored as global tables, or on object labels.

Table.query()

static Table query( string queryStr , lambda p1 ... p9 = 0 )

Parameters

queryStr The sql query.
p1-p9 Only used if you include $ syntax in the query. This defines additional, dynamically evaluated parameters associated with the query. The value is a "lambda", a type that simply signifies that the parameter is evaluated as-needed, not immediately when the method is called. You will usually either pass a reference to a table node here, defining the table to query, or you will use the $iter() command in a FlexScript expression to dynamically determine the value of a cell in a "virtual table." If this parameter defines a table, it must be a tree-bound table or a direct reference to a node. In other words, it cannot be the result Table of another call to Table.query(), unless you clone that result to a tree-bound table with Table.cloneTo(). See Sql Query Examples for more information.

Returns

Table The resulting table. This is a read-only in-memory table (it is not stored on a node in the tree). Use Table.cloneTo() to copy the result to a tree-bound table.

Description

Executes an SQL query, returning the result as a Table.

Table result = Table.query("SELECT * FROM Customers ORDER BY Name");

See Sql Query Examples for more information.
