SQL Optimizer for DB2 LUW 4.4.1 - Installation Guide

Member and Argument Lookup

Member and argument lookup are lookup hints to help construct SQL statements.

Member lookup displays the list of database object members for schemas, tables, views and alias.; For example, if a table name or alias is typed followed by "." then the corresponding lookup hint will be the column names. CTRL+SPACE can be used as short-cut keys to bring up the member lookup.

Argument lookup displays the next argument parameter for functions and procedures. For example, if a procedure name is typed followed by "(" then the list of arguments is shown highlighting the next enterable argument. CTRL+SHIFT+SPACE can be used as short-cut keys to bring up the argument lookup.

To enable or disable the member and argument lookup

  1. Click image\B_Options.gif.

  2. Select the Editor tab.

  3. Under the Lookup section, select the Member lookup and/or the Argument Lookup checkboxes .

Member lookup (Default)

Specify whether to show the lookup hint for database object members.

Argument lookup (Default)

Specify whether to show the argument parameters hint for functions and procedures.

Delay (Default = 0.75 sec , Range = 0.5 to 1.5 sec )

Specify the minimum delay time for the lookup hint to appear.

Note: The member lookup selects the information about the database objects from the system view. Since the system view does not contain the information about temporary tables, member lookup does not find the columns in temporary tables.
