• Empty string ("") if there is no lock or if the data file used is not a HFSQL Client/Server data file.
• Information about the lock. This information is separated by TAB characters and it has the following format:
  
  <Nom physique du fichier de données relatif à la database> + TAB +
  <Numéro d'enregistrement> + TAB +
  <Utilisateur> + TAB + <Nom de la machine cliente> + TAB +
  <Adresse IP de la machine cliente> + TAB + <Nom de l'application cliente> + TAB +
  <Type de blocage> + TAB + <Date de pose du blocage> + TAB +
  <Nombre de secondes depuis lequel le blocage a commencé> + RC
  • <Record number> is set to -1 if the lock was set on the data file.
  • The <Type of lock> parameter can correspond to:
    • W: Lock in write mode.
    • RW: Lock in read/write.
    • W-T: Lock in write mode set by a transaction.
    • RW-T: Lock in read/write set by a transaction.
  • <Start date of lock> has the following format: YYYYMMDDHHmmSS. This date is in UTC format (Universal Time Coordinated).

Name of the data file used.
If this parameter is an empty string (""), HInfoLock manipulates the last data file used by the last HFSQL function (function starting with "H").

Number of the record for which the lock information is requested.
If this parameter is not specified, function HInfoLock lists all of the data file.

Information about the lock. This information is separated by TAB characters and it has the following format:

<Nom physique du fichier relatif à la database> + TAB + <Numéro d'enregistrement> +
TAB + <Utilisateur> + TAB + <Nom de la machine cliente> + TAB +
<Adresse IP de la machine cliente> + TAB + <Nom de l'application cliente> +
TAB + <Type de blocage> + TAB + <Date de pose du blocage> + TAB +
<Nb de secondes depuis lequel le blocage a commencé> + RC

• <Record number> is set to -1 if the lock was set on the data file.
• The <Type of lock> parameter can correspond to:
  • W: Lock in write mode.
  • W-T: Lock in write mode set by a transaction.
  • RW: Lock in read/write.
  • RW-T: Lock in read/write set by a transaction.
• <Start date of lock> has the following format: YYYYMMDDHHmmSS.

Connection for which the lock information is requested. This connection corresponds to:

• the name of the connection defined in the data model editor or with HDescribeConnection or HOpenConnection.
• the name of a variable of type Connection.

If this parameter does not correspond to a connection name, the HInfoLock function considers that this parameter corresponds to a data file name.

Full path of the data file, relative to the database defined by the <Connection> parameter.
If the <Connection> parameter matches the logical name of a data file, this parameter is ignored.
If this parameter is not specified, all the locks set on all the data files of the database are returned.

Number of the record for which the lock information is requested.
If this parameter is not specified, function HInfoLock lists all of the data file blocks.
