Solution 1

You need quotes in your query try:

SQL

BEGIN
DECLARE @T VARCHAR(20)
DECLARE @QRY NVARCHAR(200)
SET @T='X'
SET @QRY='SELECT * FROM [dbo].[LIBMAST] WHERE CALLNO LIKE ''%'+@T+'%''';
EXEC(@QRY)
END

Solution 2

Quotes my friend, quotes.
Change:

SQL

SET @QRY='SELECT * FROM [dbo].[LIBMAST] WHERE CALLNO LIKE %'+@T+'%'

To

SQL

SET @QRY='SELECT * FROM [dbo].[LIBMAST] WHERE CALLNO LIKE ''%'+@T+'%'''

Hi Josh,

Try This.....

SQL

BEGIN
    DECLARE @T VARCHAR(20)
    DECLARE @QRY NVARCHAR(200)
    SET @T='X'
    SET @QRY='SELECT * FROM [dbo].[LIBMAST] WHERE CALLNO LIKE ''%'+@T+'%'''
    PRINT @QRY 
    EXEC(@QRY)
END

(or)

SQL

BEGIN
    DECLARE @T VARCHAR(20)
    DECLARE @QRY NVARCHAR(200)
    SET @T='X'
    SET @QRY='SELECT * FROM [dbo].[LIBMAST] WHERE CALLNO LIKE '+CHAR(39)+'%'+@T+'%'+CHAR(39)
    PRINT @QRY 
    EXEC(@QRY)
END

You missed Single Quote in String Comparison.
