parameter for text
In Access 2003.
In a form I have a parameter to search for a word at a a time Like [Froms].[Form].txtWords]&"*" which works well. .. In order to enter more than two oarameter separated by commas in txtwords I have been tryin the Str function like this "Instr([txtWords])" "Instr[txtWords]" The query displays no records at all. Could you suggest me how to do it Many thanks |

I would suggest separating by space and using this --
Like "*" & [Froms].[Form].txtWords] &"*" Remember that when you type in 'bell' you will also get 'bellows' in the results. -- Build a little, test a little. "sebastico" wrote: In Access 2003.

Karl Thanks for your reply. I'm sorry. I wrote the instruction wrong. It must be: Like [Forms].[Form].[txtWords]&"*" Nevertheless, as you suggested I tested again: Like "*" & [Forms].[Form].[txtWords] &"*" . If I enter one word it works but If I enter two words separated by space, query shows nothing. I don't know why. Any idea is welcome "KARL DEWEY" wrote: I would suggest separating by space and using this -- Like "*" & [Froms].[Form].txtWords] &"*" Remember that when you type in 'bell' you will also get 'bellows' in the results. -- Build a little, test a little.

I missed this one.
Place [Forms].[Form].[txtWords] in the field row of the query design grid. In the criteria row put -- Like "*" & [YourTableName].[FieldBeingSearched] &"*" -- Build a little, test a little.

Karl With your parameter: If I enter one word (any stored in the table), the parameter displays all records (same as I have in the table). If I enter two words displays all records as well.

Could you suggest me how to do it I don't think it's doable. If the field you were searching contained only single words and you were trying to match the entire word, the Instr solution can work. But since you are doing pattern-matching using LIKE, there is no way to search for multiple patterns without using OR to combine them: Like [txtword1] & "*" OR Like [txtword2] & "*" It appears you will need to provide multiple textboxes and instruct the users to enter a single search pattern into each. -- HTH, Bob Barrows |

Bob The field I'm searching has one or more words. Can I enter one, two or three words or do I have to use more txtboxes? Thank you for your help "Bob Barrows" wrote: sebastico wrote: In Access 2003.

You will need a separate textbox for each pattern for which the user wishes
to search. This of course, will be problematic. If you provide two textboxes, the users will tell you they need a third. After you provide that one, they will of course demand a 4th ... ad nauseam You might consider a keyword-table approach, especially if users will only ever be searching for whole words. This will involve creating a table that includes the key field(s) from the first table, plus a single field for the keywords. You would probably want to exclude "nuisance" words from the keyword list: "the", "to", "a", etc. Including them would cause too many unrelated results to be returned in searches (Google has a similar approach). The result would be like this: Sourcetable: ID textfield 1 A phrase with several words Keywords: ID Keyword 1 phrase 1 several 1 words Your criterion would be in the ID field and would look like this*: IN (Select ID FROM keywords WHERE "," & [txtwords] & "," LIKE "*," & [keyword] & ",*" ) *This is untested and was included only to provide a general idea for how to approach this. sebastico wrote: Bob The field I'm searching has one or more words.

Could you suggest me how to do it Many thanks You wouldn't be able to do this directly if you want to search for multiple words You could use SPLIT to break out the separate words (and maybe use TRIM to cut off the leading and trailing space). Then you would have to loop through the array and AND them to the filter. Not trivial, but doable. -- Message posted via AccessMonster.com http://www.accessmonster.com/Uwe/For...eries/201005/1 |
