USER MANUALS

Listing Elements in the Catalog

The LIST command returns a list of elements names. E.g. a list of the names of databases, lists of the names of JDBC data sources, etc.

From the VQL Shell of Design Studio, execute HELP LIST to obtain the full syntax of these command.

The optional clause ON <database name> of some of the LIST commands allows obtaining the list of that type of elements on a different database from the one you are connected to.

Elements in the Server

  • LIST DATABASES lists the existing databases.

  • LIST FUNCTIONS returns the name and syntax of all the functions available. This list includes the functions available out of the box and the custom functions developed by the user and uploaded to the Server.

    The output of this command may change in future versions of the Denodo Platform.

  • LIST FUNCTIONS CUSTOM returns the name and syntax of the custom functions developed by a user and uploaded to the Server.

    The output of this command may change in future versions of the Denodo Platform.

  • LIST GLOBAL_SECURITY_POLICIES returns the global security policies existent at Virtual DataPort (see section Global Security Policies)

  • LIST I18NS lists the names of the available i18n. To obtain the configuration of a specific one, execute DESC VQL MAP I18N <name of the i18n>.

  • LIST JARS lists the jar extensions (see section Defining JAR Extensions). This command lists the jar files users imported executing the command CREATE JAR or from the “Extension Management” dialog of Design Studio.

  • LIST MAPS lists maps of the type simple or i18n (see section Defining a Map).

  • LIST OPERATORS lists the operators that are applicable on a given data type: int, double, float, text, etc.

  • LIST POLICIES lists the custom policies. The section Custom View Policies of the Developer Guide explains what they are, how to develop them and how to import them into Virtual DataPort.

  • LIST RESOURCE_MANAGER { RULES | PLANS } lists information about the rules or plans defined in the Resource Manager.

  • LIST ROLES lists the roles (see section Managing Users).

  • LIST TAGS lists the tags existent at Virtual DataPort (see section Tags).

  • LIST USERS lists the user’s roles (see section Managing User Roles).

Elements in the database you are connected to

  • LIST ASSOCIATIONS lists the associations (see section Associations).

  • LIST DATASOURCES lists the data sources of the type specified (see section Specifying Paths in Virtual DataPort).

  • LIST LISTENERS JMS lists the listeners JMS (see section Defining JMS Listeners)

  • LIST PROCEDURES lists the Denodo stored procedures.

  • LIST RESOURCES lists the resources the administrators uploaded using the Extension Management wizard of Design Studio.

  • LIST TYPES shows all data types from the catalog or only those of a certain type (array or register).

  • LIST VIEWS lists the derived views of the database.

    If the clause ALL is present, it returns the list of base and derived views.

    If the clause BASE is present, it returns the list of base views.

  • LIST VIEWSTATSUMMARIES lists the views that have statistics that can be used by the Cost-based optimization (see section Defining the Statistics of a View).

  • LIST WEBSERVICES lists the published Web services (see section Publication of Web Services).

  • LIST WRAPPERS lists wrappers of the specified type (see section Generating Wrappers and Data Sources).

<datasource type> ::=
    CUSTOM | DF | ESSBASE | JDBC | JSON | LDAP | MONGODB | ODBC | OLAP | SALESFORCE |
  | SAPBWBAPI | SAPERP| WS | XML

<resource type> ::=

For example, to list the existing databases the following statement is executed:

LIST DATABASES;

To list the maps of the type i18n the following statement is used:

LIST MAPS I18N;

To list the JDBC data sources of the support database:

LIST DATASOURCES JDBC on support;
