View Execution Plan(S)
The View Execution Plan(S) feature can be accessed through the command line interface.
To capture and then display the execution plan for a query, use the following command:
VEComp -ie <Logon specifications> [-db <default database>]
[-d <qcdname>] <SQL Statement> [-t <query tag>]
SQL Statement
{
{-q <SQL test>} || {-f <SQL file> } SQL file is assumed to be text file.
}
If the -d option is not specified, then "qcd" is used by default.
To capture and then display the execution plan in XML for a query, use the following
command:
VEComp -iex <Logon specifications> [-db <default database>]
[-d <qcdname>] <SQL Statement> [-t <query tag>]
To display the execution plan in XML for a query, without storing on the database, use the following command:
VEComp -eix <Logon specifications> [-db <default database>] <SQL Statement>
Table 45 describes commands used with View Execution Plan(S).
