Member and Argument Lookup

Editor Functions > Member and Argument Lookup

Member lookup enables you to select the database objects or column names from a list as you create a SQL statement. Argument lookup provides hints for functions and procedures to help construct SQL statements. Both of these functions automatically display as you type the appropriate corresponding text in the SQL statement.

Member lookup displays the list of database object members for databases, users, tables, views and alias. For example, if a table name or alias is typed followed by "." then the corresponding lookup hint is the column names. You select the item from the list and it is entered in to the text. The [Ctrl+Space] can be used a short-cut key 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. You cannot select items from the Argument lookup list. It provides a guide to help you determine what you should enter as a value for the function or procedure. The [Ctrl+Shift+Space] can be used as a short-cut key to bring up the argument lookup.
