The package file provides the necessary functions to treat files from XSQL-Script. Files can be created, removed, edited, read them, stored in the database... The following table shows the most important functions, separateds by differents aspects as: Binary or Character functions. Functions which reference a file via an identifier or directly through an argument in which is passed the file. Functions to which you can indicate the character set and to which you cannot.
1 Xsql file
|Functions which reference to the file with the attribute id
|Functions to which the file is passed as entry argument.
It is discouraged the use of the functions
file.out, being preferable to use the funtions
|application server $HOME/temp, a temporal file. It is the default option.
|application server filesystem, a file of absolute path.
|wic_conf:wic_user_diskdata, a entry to disktool.
|wic_conf:wic_user_maildata, a entry to mailtool.
Annex to the table 'File mode':
- privileged: For security the interpreter who executes the program XSQL-Script does not let any directory of the file system be accessed.
In the configuration database wic_conf the directories to which the XSQL-Script programs executed on a given server can access are determined.
- yes_ The server allows the acces to the enabled directories (parametrized for each of the servers WebStudio in the configuration database wic_conf).
- no: if the file is temporal is located in temporal directories of the file system.
- location: location of a file.
- final: The file is founded by the indicated name.
- base: if the file is temporal, the final name of the file has a randomly generated part and the indicated name forms the base of the final name.
- persistent: existence of the file.
- yes: The file is persistent, it will exist after the ending of the program.
- no: The existence of the file is limited to the execution time of the XSQL-Script. Once the program ends, it is removed.
