IBM DB2 Universal Database SQL Explain Tool
SQL Explain describes the access plan selection for static SQL statements
in the packages stored in the DB2 Universal Database system catalogs.
Given a database name, package name, package creator, and section number,
SQL Explain will interpret and describe the information in these catalogs.
The syntax is:
.-----------.
V |
--db2expln----<option>--+--><
where <option> and <parameter> are taken from the list below. Each <option>
may appear only once, and they may be specified in any order.
Connection Options:
-database <db> = Connect to the database named <db>.
-d <db>
-user <name> <pw> = Connect as user <name> with password <pw>.
-u <name> <pw>
A database name must be specified.
Output Options:
-terminal = Send output to the terminal.
-t
-output <file> = Write output to the file named <file>.
-o <file>
Either terminal or file output must be specified.
Help Options:
-help = Display this help text.
-h
-?
Package Options:
-schema <pattern> = The package creator must match <pattern>.
-c <pattern>
-package <pattern> = The package name must match <pattern>.
-p <pattern>
-version <pattern> = The package version must match <pattern>. If not
specified, then the package with the version ''
(the empty string) will be explained.
-section <number> = The section number is <number>. Use 0 (zero) for
-s <number> all sections in the package.
-escape <charater> = Use <character> as the escape character when
-e <character> matching patterns.
-noupper = Do not upper case creator, package and version
-l before matching.
The creator and package information must be specified unless dynamic SQL is
being explained. If the section information is not specified, then all
sections will be displayed.
The <pattern> for creator, package, and version is in LIKE predicate form,
which allows the percent sign (%) and underscore (_) as pattern matching
characters. This allows multiple packages to be explained with one
invocation of db2expln. The escape character can be used to force the %
and _ characters to be treated literally. (See the SQL Reference for more
information on the LIKE predicate.) If multiple packages may be matched,
the section number is automatically set to 0 (all sections).
Dynamic Statement Options:
-statement <statement> = The dynamic statement <statement> will be
-q <sql> explained.
-stmtfile <file> = The dynamic statements contained in the file
-f <file> <file> will be explained. <File> must exist at
the client.
-noenv = By default, db2expln will invoke each dynamic SET
statement after it has been explained. This option
prevents the execution of these statements.
Explain Options:
-setup <file> = The SQL statements in <file> will be invoked
before any sections or statements are explained.
The SQL statements in <file> will not be
explained. Errors in the setup script are reported
but ignored.
-terminator <character> = Each SQL statement for -statement and -setup ends
-z <character> at <character>. If this option is not specified,
then each statement is assumed to be one line
long.
-graph = Reconstruct the original optimizer plan graph (as
-g presented by Visual Explain). Note that the
reconstructed graph may not exactly match the
original plan.
-opids = Show the operator ID numbers.
-i
The specific options available may vary by database server.
Use "db2expln -help -database <db>" to get the options available for
a specific server.
