Databases argument_3 – the search option. Possible options are: 0 – find the nearest value; -1 – find the nearest floor value; 1 – find the nearest ceiling value. argument_4 – the parameter indicating the structure of the column subject to the search. It indicates how the values are ordered in the column. The value 0 means the entries are not ordered, forcing the search over all records in the database. The value 1 means the column is ordered ascending or descending. The search completes once the difference between the sought value and the value in the current column of the database is greater than in the previous one. The parameters argument_3 and argument_4 are optional. If those are not specified, the default values are used: argument_3 = 0; search for the nearest value; argument_4 = 0; the column is not ordered; Function VAL val ( record_number, database_field ), where record_number - is an arbitrary numerical expression yielding an integer. database_field - the reference to the field. Example: val ( 4, BASE.H ) This call means: get the value from the record number 4 of the field H in the database BASE. Function FIND find ( database_field, condition_1, condition_2, ... ) This function combines the previous two. The function returns the value of the specified field database_field from the record satisfying the conditions condition_1, condition_2. If such record is not found, the function signals the error “Incorrect record number”.To get the parameter values for the drawing of the bushing from the internal DB, use the function FIND (). To do this, enter the variable editor by using the command “V: Edit Variables” and define the expressions for the variables as shown on the right hand side diagram. Thus, we have created a parametric drawing of a bushing. The values of the drawing elements will be selected from the internal database BASE depending on the value of the inner bushing diameter d. In this way, you create a whole family of bushings for latches and mounting rods per GOST 12215-66 by creating a parametric drawing of the bushing and connecting it to the DB. 527
Fundamentals. Two-Dimensional Design 528 By using this example we have reviewed the main steps of creating databases in T-FLEX CAD. Now, let's review the full set of the database editor commands. Database Editor Commands Any available command can be called by one of the following means: from the textual menu, via the icons in the toolbar, or by pressing the appropriate key combination on the keyboard. All available commands can be found in the textual menu. The commands in the textual menu are grouped by their purposes. The group “File” includes the commands for managing the database itself : creating a new one, loading an existing one, saving and deleting, as well as the command for exiting the editor. Create new database Keyboard Textual Menu Icon “File|New Database” Allows creating a new internal database or a database by reference. Open internal database Keyboard Textual Menu Icon “File|Open Internal Database” Opens an existing internal database or a database by reference. When called, this command displays the list of all existing databases in the current drawing. The databases by reference are marked with an asterisk. Open external database Keyboard Textual Menu Icon “File|Open External Database” Allows opening database files in dBASE format (the files with the extension .DBF). The command brings up the standard dialog box for opening files. Save Database Keyboard Textual Menu Icon “File|Save” Saves the changes to the current database. The data is saved in the same format as the one used when loading the database . Save Database As Internal Keyboard Textual Menu Icon “File|Save As Internal Database” None Allows saving the loaded database as internal, regardless of the original format. This command provides the capability of converting an external database or a database by reference into an internal one.
