Example

See additional examples

// Create the statistical file for January
HChangeName(Stat, "JanuaryStatistics")
HCreation(Stat)

Syntax

<Result> = HChangeName(<Data file> , <Physical name>)

<Result>: Boolean

True if the operation was performed,
False if a problem occurred. HError is used to identify the error.

<Data file>: Character string (with or without quotes)

Name of data file (defined in the analysis). This name is used by all the functions for handling the HFSQL data files.

<Physical name>: Character string (with quotes)

New physical name of the data file.
If this parameter is an empty string (""), the physical name used will correspond to the physical name defined in the analysis.
This parameter must contain no drive name and no directory name.
This name will be stored when closing the data file.
The ..PhysicalName property allows to know the physical name given to the data file by the HChangeName function.
According to the database used, the physical name of the data file can be prefixed by the name of the database or by the name of the user. In this case:
the full physical name is indicated in the description of the data file under the analysis editor (option "Name of the table in the external database").
HChangeName can also be used to change the physical name of the data file. See Use with Native Connectors and/or OLE DB provider.

Remarks

Use conditions

The data file must be closed in order for this modification to be taken into account (use HClose if necessary), otherwise the modification will be taken into account during the next opening.
XML: HChangeName modifies the name of the XML TAG associated with the data file described in the analysis (does not change the physical name of the file). To change the name of the file, you must use a connection (HDescribeConnection by specifying the name of the XML file as data source) and associate this connection with the file via HChangeConnection.

Multiple changes of name

HChangeName can be called several times with different parameters. When the physical name is redefined several times for the same logical name, the last physical name that was given replaces all the other ones.

Changing the drive or the directory

HChangeName can only be used to change the name of the physical file. To modify its location, use HChangeDir and HSubstDir.

Function HChangeName: Use with Native Connectors and/or OLE DB provider

By default, the logical name supplied to HChangeName is considered as being the only name of the table. It is encapsulated by using the encapsulation characters corresponding to the database or specified by the OLE DB provider before being sent to the database (this is used to manage the table names containing special characters).

To give a file name made of <User name>.<Table name> to HChangeName, these names must be already formatted (by using the encapsulation characters corresponding to the database or specified by the OLE DB provider).

Example for SQLServer:
The encapsulation characters are " ".
To change CUSTOMER into DBO.CUSTOMER with HChangeName, you must pass "DBO"."CUSTOMER".
Therefore, the following code must be used:

HChangeName(CUSTOMER, """DBO"".""CUSTOMER""")

Various

If the management of ".REP" is enabled (HSetREP), the modification of the path is saved in the ".REP" file (see management of .REP).
The function HChangeName is equivalent to the function HSubstName available in WINDEV 5.5/WEBDEV 1.5.
