Purpose
SQLLanguages() returns
SQL dialect or conformance information. The information is returned in an
SQL result set, which can be retrieved using the same functions that are used
to fetch a result set generated by a SELECT statement.
Usage
The function returns dialect and conformance
information, in the form of a result set on StatementHandle.
This contains a row for every conformance claim the SQL product makes (including
subsets defined for ISO and vendor-specific versions). For a product that
claims to comply with this specification, the result set thus contains at
least one row.
Rows defining ISO standard and vendor-specific languages
can exist in the same table. Each row has at least these columns and, if it
makes an X/Open SQL conformance claim, the columns contains these values.
