Stored procedures
Adds a row into:
  • a Table control,
  • a TreeView Table control,
Note: It is recommended to use TableAddLine. TableAddLine is used to add:
  • TAB characters into the columns,
  • all types of values into the columns.
Versions 18 and later
WEBDEV - Server codePHP This function can now be used to handle the TreeView Table controls in the WEBDEV and PHP sites.
New in version 18
WEBDEV - Server codePHP This function can now be used to handle the TreeView Table controls in the WEBDEV and PHP sites.
WEBDEV - Server codePHP This function can now be used to handle the TreeView Table controls in the WEBDEV and PHP sites.
Versions 19 and later
WEBDEV - Browser code This function is now available in Browser code for Table controls in browser mode.
New in version 19
WEBDEV - Browser code This function is now available in Browser code for Table controls in browser mode.
WEBDEV - Browser code This function is now available in Browser code for Table controls in browser mode.
Example
// Add "Moore", "Vince" and "06/21/72"
// at the end of the "TABLE_CustomerTable" control
ResAdd = TableAdd(TABLE_CustomerTable, ...
"Moore" + TAB + "Vince" + TAB + "06/21/72")
Syntax
<Result> = TableAdd(<Table control> [, <Row>])
<Result>: Boolean
  • True if the element was added,
  • False otherwise.
<Table control>: Control name
Name of control to use. 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 process belongs will be used.
<Row>: Optional character string
Row to add. This row has the following format:
<Element of column 1> + TAB + <Element of column 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 multiselection control.
    WEBDEV - Server codePHP Reminder: Multiselection controls are available in Ajax only WEBDEV - Server codePHP Reminder: Multiselection 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.

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_CustomerTable, "Moore" + TAB + "Vince" + ...
    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_CalcTable, (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).

Various

  • 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

..NewLine is used to find out whether the current row was just created by TableAdd (..NewLine = True).
WEBDEV - Server codePHP

Cascading input

To perform cascading input, TableAdd must be used in the "Exit from a row of table" process:
IF TABLE_CustomerTable..NewLine THEN
TableAdd(TABLE_CustomerTable)
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 content of added row into the linked data file, TableSave must be used after TableAdd.
Notes:
  • The "Cascading input" option can be selected in the "Details" tab of control description.
  • Versions 19 and later
    WEBDEV - Server code The cascading input is available for the Ajax browsing Table controls only.
    New in version 19
    WEBDEV - Server code The cascading input is available for the Ajax browsing Table controls only.
    WEBDEV - Server code The cascading input is available for the Ajax browsing Table controls only.
WEBDEV - Server codePHP

Browsing Table or TreeView Table control: Adding several rows

A virtual row is created in the control whenever TableAdd is called in a browsing Table or TreeView Table control. The information will be saved in the data file during the call to TableSave.
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 the 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. See the documentation about HDescribeTrigger for more details.
WEBDEV - Server code This operating mode is available for the browsing Ajax Table controls only.

Adding images

To add an image into a 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:
      // Adds the image found in the "WB_MyApp_WEB" directory
      TableAdd(TABLE_MyTable, "MyImage.BMP")
    Note: The column must be an Image column otherwise the added image will not be displayed properly.
