5.3.1 Validating the syntax in SQL and XQuery statements
As you enter statements in the editor, the syntax of the statements is validated. The
statements are parsed to determine whether keywords and their location in the statements
are valid. The validation options that you specify determine the parser that is used.
By default, the selected parser is based on the type of database that the script is
connected to. As you can see in Figure 5.20, the Validate statement syntax for current
configuration option is selected, which means the selected parser is based on the type of
database that the script is connected to on the Configuration tab.
For example, suppose you develop a script that creates aSALES table with an index in the
DB2ADMIN schema of theGSDB database. In Figure 5.21, the script shows no syntax
errors with the DB2 for Linux, UNIX and Windows (V10.1) parser.
Figure 5.21 – Statements validated with current configuration associated with the
script
However, if you want to eventually run this script on a different database server, you can
validate it against that server type without changing your current database connection.
Simply select the option to validate the statement syntax and select a different parser from
the list. Currently, parsers for the following types of databases are available in the SQL and
XQuery editor:
• DB2 for Linux, UNIX, and Windows (V10.1)
• DB2 for Linux, UNIX and Windows (V9.8)
• DB2 for Linux, UNIX, and Windows (V9.7)
