Try Like This:
For SQL SERVER 2008+
SELECT c.name AS ColName, t.name AS TableName
FROM sys.columns c
JOIN sys.tables t ON c.object_id = t.object_id
WHERE c.name LIKE '%MyColumnaName%'
Or
SELECT COLUMN_NAME, TABLE_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%MyName%'
Or
Something Like This:
SELECT name
FROM sys.tables
WHERE OBJECT_ID IN ( SELECT id
FROM syscolumns
WHERE name like '%COlName%' )
