XML query plans in HCL Data Studio

HCL® Data Studio consists of a set of tools to use for administration, data modeling, and building queries from data that comes from data servers. The EXPLAIN_SQL routine prepares a query and returns a query plan in XML. The HCL Data Studio Administration Edition can use the EXPLAIN_SQL routine to obtain a query plan in XML format, interpret the XML, and render the plan visually.

If you plan to use HCL Data Studio to obtain Visual Explain output, you must create and specify a default sbspace name for the SBSPACENAME configuration parameter in your onconfig file. The EXPLAIN_SQL routine creates BLOBs in this sbspace.
