Getting Started with IBM Data Studio for DB2

• DB2 for z/OS (V10)
• DB2 for z/OS (V9)
• DB2 for i
• Informix
Note:
Version-specific syntax checking for DB2 for Linux, UNIX, and Windows prior to V9.7
uses the DB2 V9.7 parser.
For example, suppose you want to use the script that creates theTESTTABLE table with its
index in a database on a DB2 for z/OS V10 server. To validate the script for the target
database, you can simply change the parser to DB2 for z/OS (V10), which you can do
while the script is still connected to the current database.
In this case, theALLOW REVERSE SCANS clause in theCREATE INDEX statement is
invalid with the DB2 for z/OS V10 parser. The editor flags the validation error with red
markers in the left and right margins and underlines the invalid syntax with a red squiggly
line. As shown in Figure 5.22, you can review the message for a syntax error by hovering
over the error marker in the margin.
