SQL query that returns records with 'mytext' found in any column?

Is there a way to build a query that will return all records with a specified text found in any of the  columns?

I'm trying to implement a global seach on our database for when a keyword is known but the correct column is not known.

If not . . . . how would I go about building a stored procedure that does this?

Thanks!

That's been done and here's a link to one version of it.

I googled "sql search all tables" and that's the first hit.  Run the same search and you'll get more.

hey

please check modified query in the above link posted by brandon...

DECLARE @SearchStr nvarchar(100)   
   SET @SearchStr = 'television'  
     
   CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))  
  
   SET NOCOUNT ON  
   DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)  
  
   SET  @TableName = ''  
   SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')  
  
   WHILE @TableName IS NOT NULL  
   BEGIN  
         SET @ColumnName = ''  
  
         SET @TableName =   
         (  
               SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))

This is a good start . . .but I only want to search all columns of ONE table (basically a support issue table and I don't know if the keyword will be in the subject, body, module name, contract number, etc.)

I think I can take the above procedure and modify it to work with just one table, but I would like to make sure there isn't a better way to do it if I only need results from one table.

If it's just one table, and you only have 4 columns, then just write a simple query.



select * from SomeTable
where subject like '%SomeText%'
or body like '%SomeText%'
or modulename like '%SomeText%'
or contractnumber like '%SomeText%'

This is exactly what I needed.  I had way more than 4 columns . . but I just added all of the columns and built the query in my program.

Thanks!
