Stored procedures
Adds a row into:
  • a Table control,
  • a TreeView Table control,
Remark: It is recommended to use TableAddLine. TableAddLine is used to add:
  • TAB characters into the columns,
  • all types of values into the columns,
  • UNICODE data automatically and without conversion.
Versions 18 and later

WEBDEV - Browser code This function is now available in Browser code for Table controls in browser mode.
Example
// Ajout de "Dubois", "Pierre" et "21/06/72"
// à la fin du champ "TABLE_TableClient"
ResAjout = TableAdd(TABLE_TableClient, "Dubois" + TAB + "Pierre" + TAB + "21/06/72")
Syntax
<Result> = TableAdd(<Table control> [, <Row>])
<Result>: Boolean
  • True if the element was added,
  • False otherwise.
<Table control>: Control name
Name of the control to be used. This control can correspond to:
  • a Table control.
  • a TreeView Table control.
If this parameter corresponds to an empty string (""), the control to which the current event belongs will be used.
<Row>: Optional character string
Row to add. This row has the following format:
<Elément de la colonne 1> + TAB + <Elément de la colonne 2> + TAB + ...

If this parameter is not specified, an empty row is added into the control. For a browsing control, the default values defined in the linked data file are taken into account.
Remarks

Use conditions

TableAdd can be used on:
  • a browsing or memory control,
  • a single-selection or multi-selection control.
    WEBDEV - Server codePHP Reminder: Multi-selection is not available for Table controls in classic mode.
WEBDEV - Server codePHP This function is available for Table controls in Ajax mode, Table controls in classic mode and TreeView Table controls.
WEBDEV - Browser code This function is available for Table controls in browser mode only.
WEBDEV - Browser code The TreeView Table control is not available.
WEBDEV - Browser code The TreeView Table control is not available.

Characteristics of a row

  • Each added element is converted into the type of the relevant column.
  • To specify no value for an element, use an empty string ("") or 0 (according to the type of column). For example:
    TableAdd(TABLE_TableClient, "Dubois" + TAB + "Pierre" + TAB + "" + TAB + "21/06/72")
  • If an element corresponds to the calculation result, the numeric expression must be enclosed in brackets. For example:
    TableAdd(TABLE_TableCalcul, (53+29) + TAB + (83-21))

Position of added row

By default, the row is added at the end of the rows displayed by the control.
Special case:
  • If the control is sorted by TableSort, the added row is positioned in the control according to the current sort.
  • If the control is sorted by the user, the sort is ignored when inserting the row. The row is added at the end of control.

Limits: Maximum number of rows displayed

The maximum number of rows that can be displayed in a Table or TreeView Table control is limited by the amount of available memory (theoretical maximum: 2 billion rows).
However, we do not advise you to use large Table or TreeView Table controls for performance and user-friendliness reasons (time required to fill the control for example).

Miscellaneous

  • To add a row at a specific position in a Table or TreeView Table control, use TableInsertLine.
  • If the added row is the first row of the control, the added row becomes the current row.
WEBDEV - Server codePHP

Adding rows

The New property is used to determine if the current row has just been created by TableAdd function (New = True).
WEBDEV - Server codePHP

Cascading input

To perform a cascading input, TableAdd must be used in the event "Exit from a row" of the Table control:
IF TABLE_TableClient.Nouveau THEN
TableAdd(TABLE_TableClient)
END
WEBDEV - Server codePHP This operating mode is available for Table controls in Ajax mode only.
WEBDEV - Server codePHP

Browsing Table or TreeView Table control: Modifications in the linked data file

  • If the cascading input is enabled, the data file linked to the control is automatically modified when the user goes to the next row.
  • If the cascading input is not enabled, the data file linked to the control is not modified. To write the contents of the row added in the data file linked, it is necessary to use the function TableSave after the function TableAdd.
Remarks:
  • The "Cascading input (Addition)" option can be selected in the "Details" tab of the control description.
  • Versions 19 and later
    WEBDEV - Server code The cascading input is available for Ajax browsing Table controls only.
    New in version 19
    WEBDEV - Server code The cascading input is available for Ajax browsing Table controls only.
    WEBDEV - Server code The cascading input is available for Ajax browsing Table controls only.
WEBDEV - Server codePHP

Browsing Table or TreeView Table control: Adding several rows

Each time the TableAdd function is called in an Table control or hierarchical table file, a virtual row is created in the control. The information will be saved in the linked data file only when TableSave is called.
If TableAdd is successively called in the same process without being followed by TableSave, only the FIRST call is effective (the following calls are ignored). A single row is added into the browsing Table or TreeView Table control.
WEBDEV - Server codePHP This operating mode is available for browsing Ajax Table controls only.
WEBDEV - Server code

Adding a record into a browsing Table control and releasing a trigger

You have the ability to release a trigger when a record is added into a browsing Table control. For more details, see the documentation about HDescribeTrigger.
WEBDEV - Server code This operating mode is available for browsing Ajax Table controls only.

Adding images

To add an image into a Table or TreeView Table control:
  • WEBDEV - Server codePHP specify the path and name of image to add. The path is relative to the "<Project_Name>_WEB" directory.
    For example:
    // Ajoute l'image située dans le répertoire "WB_MonAppli_WEB"
    TableAdd(TABLE_MaTable, "MonImage.BMP")
Remark: The column must be an Image column otherwise the added image will not be displayed properly.

Unicode management

You can define how Unicode will be managed in the project configuration ("Unicode" tab of the configuration description window):
  • If the "Use ANSI strings at run time" option is selected: the data is converted using the current character set.
    Reminder: ChangeCharset changes the current character set.
  • If the "Use UNICODE strings at runtime" option is selected, the data is inserted without being converted,
