Syntax

Saving in a data file Hide the details

TableSave(<Table control>)
<Table control>: Control name
Name of the browsing Table control to be used. The current row of this Table control will be saved.
If this parameter corresponds to an empty string (""), the Table control to which the current process belongs will be used.
Versions 20 and later
WINDEV

Saving in an object (syntax mainly available for the MVP) Hide the details

TableSave(<Table control> , <Object name>)
<Table control>: Control name
Name of Table control on variable to use.
If this parameter corresponds to an empty string (""), the Table control to which the current process belongs will be used.
<Object name>: Character string
Name of object to use. The content of the current row found in the Table control will be saved in the members of the associated object.

Remarks

Use conditions

TableSave can be used on:
  • a browsing Table control or a browsing TreeView Table control.
  • a single-selection or multi-selection control. For a multi-selection control, only the last selected record is modified (the record corresponding to the last current row).
  • Versions 20 and later
    WINDEV a Table control on variable (syntax 2).

Updating the data file linked to the Table or TreeView Table control

TableSave saves the current control row in the data file linked to the control. The items are automatically assigned with the values of associated columns in the current row.
When a modification is performed, TableSave replaces the former values by the new ones. The items not found in the control are not modified.
Caution:
  • TableSave only manages the data file associated with the control. If some columns are linked to items found in other data files, these data files are not automatically managed.
  • The "image" columns are not saved by TableSave. To modify the content of the memo associated with the image (rare case), use HLinkMemo.
  • In the Check Box columns, the call to TableSave is implicit and it cannot be disabled. In any case, the modification of the value of check box will be applied to the data file.

Cascading input and update of linked data file

  • If the cascading input is enabled, the data file linked to the Table or TreeView Table control is automatically modified when the user goes to the next row (use of TableAdd, TableAddLine, TableInsert, TableInsertLine, TableModify and TableModifyLine). TableSave is useless.
  • If the cascading input is not enabled, the data file linked to the Table or TreeView Table control is not modified. To write the added or modified row into the linked data file, TableSave must be used after the addition or modification function.
Remarks:
  • The Property New allows to know if the current row has just been created by the functions TableAdd, TableAddLine, TableInsert and TableInsertLine (Property New = True).
  • The Property Modified allows to know if an row has been modified by direct user input in the field (Property Modified = True).
Java The cascading input is not available for browsing Table controls with direct access. This option is available for the browsing Table controls loaded in memory.

Re-displaying the row that was saved

After the call to TableSave, the row saved may "disappear". This "disappearance" is due to the value of the search key for the added or modified record.
To avoid this problem, re-display the Table or TreeView Table control with TableDisplay.

Locking and updating the data file

If the data file is locked in the current process, TableSave saves the current row and unlocks the data file.

Duplicates and referential integrity

  • If the management of duplicates is enabled (HSetDuplicates), HErrorDuplicates must be checked after the execution of TableSave to check the key uniqueness.
  • If the management of referential integrity is enabled (HSetIntegrity), HErrorIntegrity must be checked after the execution of TableSave to check the referential integrity.

Use TableSave to reduce the number of lines of code

TableSave reduces several lines of code. This single line allows you to avoid assigning the item variables one by one.
For example, the following code:
Client.Nom = ColonneNom
Client.Prénom = ColonnePrénom
Client.Adresse = ColonneAdresse
Client.CP = ColonneCP
Client.Ville = ColonneVille
HAjoute(Client)
is replaced with the following line:
TableSave(TABLE_Client)
