使用存储过程搜索字符串

Question

How can I pass paramenter into a stored procedure and use it to search the database?

I am trying to search the database for a business name which has the search term within it.

The following SP can be used to return all results:

BEGIN

SELECT company.businessname
FROM company;

END

Returns this result:

Better Cats Vetinary Practice
Appliance R'Us
The Beautiful Flower Company
Lovely Trips Away

However, if I use the 'searchtext' parameter which is passed in like this, and that parament is given the value of 'appliance' it should return one result, but returns nothing:

BEGIN

SELECT company.businessname
FROM company
WHERE company.businessname LIKE searchtext;
END

How can I get it to return the one result with 'appliance' in the business name?

Answer 1

The solution to this appears to be to put the pass the named parameter including the %...eg searchtext = %appliance%, then the SP becomes:

SELECT company.businessname
FROM company
WHERE company.businessname like searchtext;

Then it returns the result expect.ed
