Hi,

Try this, your syntax is wrong...

Example:


pphon = request.form("phon")
mySQL = "SELECT * FROM crminfo WHERE tel1 LIKE'%&pphon&%'"

Open in new window

Ooops...

Remove the ampersands '&' too...


$pphon = request.form("phon")
mySQL = "SELECT * FROM crminfo WHERE tel1 LIKE'%$pphon%'"

Open in new window

sasha85,

The ampersands are needed to use the variable.  They should be fine as you have it.

What type of field is tel1?  Even though you use a number if it is a string or text field then you need single quotes or sometype of delimiter.  What type of field is it and what database do you use?  I assume MySQL but please confirm.

Try ...

mySQL = "SELECT * FROM crminfo WHERE tel1 LIKE '%" &pphon& "%'"

Let me know if you have any questions or need more information.

sasha85,

Also, try running the query outside of your code (i.e. in MySQL or using a 'query analyser') to see if there are no results for that query.  The problem may not be a problem but just no results.

Let me know if you have a question.

If it is that type then it has to have the delimiters.  Look at the code in my last post and that should fix it.  For MySQL the delimiters for text/strings are single quotes (').  When used with LIKE the % sign would go inside the single quotes with the rest of the "string."

Let me know how it works or if you have a question.  Thanks for confirming the type of DB and field.

Sorry, not really "last" post.  See http:#20330179.

The code is ...

mySQL = "SELECT * FROM crminfo WHERE tel1 LIKE '%" &pphon& "%'"

Please don't use all caps unless you are really yelling at me. :)  (I hope you aren't)

What is the info in that field?  How will it be used?  It seems like the info is phone number so text/string is appropriate.  If you tried to use a number type then entering 800-555-1212 would just leave -967 in that field (the math would be done).  In most cases phone numbers, zips, etc are text fields for this reason.

However if it is a number then it can be a disadvantage to use a text field type.  A detailed explanation on that can be done in a different question (one of its own) but the examples above should give you an idea.

Let me know if the suggestion above worked or not or if you have a question.
