CHANGE is an editing command that allows you to do a search and replace on the current line in the SQL buffer. The CHANGE command is also used to delete text.
C[HANGE] /old_text[/[new_text[/]]
where:
- C[HANGE]
Is the command, which may be abbreviated to C.
- old_text
Is the text you want to change or delete.
- new_text
Is the replacement text.
- /
The forward slash character is commonly used to delimit the old and new text strings, but any other character may be used as long as it is not a number or a letter, and as long as it is used consistently throughout the command.
CHANGE and all the other editing commands are described in Chapter 2.
