QUERY WRAPPER Statements¶

Virtual DataPort allows directly querying wrappers (without having to define base relations on them). To do it, use the statement QUERY WRAPPER. You have to provide the type and name of the name and optionally, a list of conditions in the format <value>, binary operator, <value> (see the syntax of condition values in the section Syntax of Functions and Condition Values). Unary operators and multivalued binary operators are not allowed.

QUERY WRAPPER { CUSTOM | DF | ESSBASE | ITP | JDBC | JSON | LDAP |
                ODBC | OLAP | SALESFORCE | SAPBWBAPI | SAPERP | WS | XML } <name:identifier>
    [
      ( <value> <binary operator> <value>
     [, <value> <binary operator> <value> ]*
      )
    ]

<value> ::= (see section Syntax Conventions)

See below the syntax to query WWW wrappers. This syntax is slightly different than for the other types of wrappers. Only a list of key = value pairs can be indicated, which will be directly received by the wrapper as input parameters.

QUERY WRAPPER ITP <name:identifier>
[
    (
        <name:identifier> = <value:literal>
        [, <name:identifier> = <value:literal>]*
    )
]
