Hi everyone,
I am using dynamic query.
Declare @testquery varchar(1000),
@test-2 varchar(200)
set @test-2 = '*Ma.01.01'
select @testquery =
'
select code,id from public where code like '% +@test + %' '
exec (@testquery)
I am getting following error
Msg 402, Level 16, State 1, Line 3
The data types %s and %s are incompatible in the %s operator
Could anyone help me to process how to use LIKE with table variable..
Thanks,
Tony

I don't see a table variable anywhere there. What's the definition of the table 'public'?

I still don't see a table variable anywhere, nor is there any definition (create table) for the table public.

@test-2 is the table variable.

Public table contains two columns.(Testcode and testid)

Using dynamic query

select @testquery =

'select testcode,testid from public where testcode like '% + @test-2 +%' '

exec (@testquery)

--testcode like '% + @test-2 +%' ' -- this Like condition is not working with table variable (@test)

Test is not a table variable. It's a scalar variable, a 200 character varchar.

Declare @testquery varchar(1000),
@test varchar(200)
set @test-2 = '*Ma.01.01'

Can you post the CREATE TABLE statement for the table public please.

CREATE TABLE PUBLIC

(

TestId INT,

TestCode Nvarchar(100)

)

Your code was a mess of string and quote-related errors.

With the table you gave me, this works.

Declare @testquery varchar(1000),

@test-2 varchar(200)

set @test-2 = '*Ma.01.01'

select @testquery = 'select TestCode, TestId from [public] where TestCode like ''%' +@test + '%'' '

exec (@testquery)

As Gail said, there are no table variables. Your problem is with how you're plugging your variable into the dynamic select statement.

Try this for the dynamic select, the wild card '%' should work appropriately.

'select code,id from public where code like ''%' + @test-2 + '%'''

Three minutes too slow on a Friday morning.

Tony,

A great way to troubleshoot dynamic SQL related errors is to print the statement instead of trying to execute it.

Change exec (@testquery) to print @testquery and you'll see the select statement that is trying to be executed. Sometimes it makes obvious otherwise mysterious errors.

This doesn't work, I am getting an error

Msg 402, Level 16, State 1, Line 369

The data types varchar and varchar are incompatible in the modulo operator.

I tested mine, it runs fine.

Post the exact code that is failing for you.

The data types varchar and varchar are incompatible in the modulo operator.

That means that you still don't have the quotes right because "%" is both a wild-card and a mathematical operator. The code Gail posted works just fine.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
