TABLE 6-3 Wildcard Characters
To find blank fields, enter Null or Is Null in the Find What text box When Access finds a record with a blank in the field, the record selector moves to the record, but the field isn t highlighted When you close the Find and Replace dialog box, the insertion point appears in the blank field, ready for you to enter data To find a zero-length string, type a pair of quotation marks: If you created a custom format for a Text or Memo field, which specifies a certain display if the field contains a null value and a different display if it contains a zero-length string, you need to watch how you apply the Search Fields As Formatted option
Looking for Wildcard Characters
The field value you re looking for could include one of the characters Access recognizes as a wildcard, such as an asterisk (*), a question mark ( ), a number sign (#), an opening bracket ([), or a hyphen (-) If you use the character directly in a search string, Access treats it like a wildcard When you use wildcards in a string to look for one of these characters, you must enclose the item you re looking for in brackets For example, to find a value that begins with B, you would use the string [ ]B* But if you re looking for a hyphen along with another wildcard character, you need to treat it a little differently Access interprets a hyphen (-) or a tilde (~) as an indication of a sequence of acceptable characters You must place it before or after all the other characters inside the brackets, not between them So if you placed an exclamation point (!) inside the brackets to indicate a match excluding the characters within the brackets, you would place the hyphen right after the exclamation point inside the brackets If you re searching for an exclamation point or a closing bracket, you do not need to use the brackets at all Just place the characters in the string with the rest
Part I:
Getting Started
In addition, be sure to select Whole Field in the Match box when you re looking for either a null value or a zero-length string
Finding and Replacing Data
A variation of the Find feature is the Replace tool, which lets you specify a value you want in the field in place of the one already there The search options are the same The only difference between the Find tab and the Replace tab is the addition of the Replace With box in which you type the replacement value To replace a certain value in a field with another value, on the Home tab s Find group, click the Find command and open the Replace tab For example, suppose you want to replace all occurrences of the word Lost in the Award Date field of the Bid Data with the words Not awarded Follow these steps: 1 Place the insertion point in the Award Date column 2 If you already have the Find dialog box open, click the Replace tab 3 Enter Lost in the Find What box and Not Awarded in the Replace With box Notice you have the same search options as with finding records
4 Click Find Next, and then do one of the following: Choose Replace to replace this instance of Lost Access moves automatically to the next occurrence Choose Find Next to skip replacing this occurrence and move to the next Choose Replace All to replace all the values without reviewing them individually 5 Access displays a message when it finishes searching the records Click Cancel to close the dialog box If you have a large amount of data to replace, you can do that faster by using an update query The only disadvantage is that the update query replaces all the values without your confirmation of individual replacements If you want to find and replace values in more than one field, the update query isn t as convenient as Find and Replace
