Reports & Queries: Unsupported WLanguage functions
Some WLanguage functions are not available in Reports & Queries. These functions are as follows: | | | HAdd | Adds the record found in memory into the data file (query or view). | | HAddGroup | Adds a group of users (HFSQL Client/Server connection) | | HAddLink | Adds an integrity rule between two files on the server. | | HAddUser | Adds a user (HFSQL Client/Server connection) | | HChangeLogDir | Modifies the location of the log files corresponding to an HFSQL file. (*JNL file and JournalOperation and JournalIdentification files if they exist). | | HCopyFile | Copies an HFSQL file from the client to the server and vice versa | | HCreation | Creates an empty data file (.FIC extension) with the index file and the memo file if necessary. | | HCreationIfNotFound | The following operations are performed by HCreationIfNotFound:- If the file does not exist, creates an empty data file (".FIC" file) with the index file and the memo file if necessary.
The function is equivalent to HCreation. - If the file exists, opens the file.
In this case, the function is equivalent to HOpen.
To optimize the call to HCreationIfNotFound, the file opening can also be performed during the first access to the file.
| | HCross | Crosses a file record. The record is deleted logically and it can be retrieved if necessary. | | HDBCreation | Ends the dynamic description of the file structure. The file that was just described is created on the disk in the path specified in HDBDescribeFile. The data, memo and index files are created on disk. | | HDelete | Deletes a record from a file (from a query or from a view). | | HDeleteDatabase | Deletes a database located on an HFSQL server.
