I want to loop throgh all the column of all the tables available in my database to check which column containts string "Kroki Homes".
I have approx. 56 tables in my database. So it is hard to check in all the columns of these 56 tables. is there any easy way to achieve this in sql server?

You can create one procedure and can pass the string for search. I found this some where this might help you.
CREATE PROC [dbo].[SearchDataFromAllTables] (#SearchStr NVARCHAR(100))
AS
BEGIN
SET NOCOUNT ON;
CREATE TABLE #Results
(
ColumnName NVARCHAR(370),
ColumnValue NVARCHAR(3630)
)
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))
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > #TableName
AND OBJECTPROPERTY(OBJECT_ID(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)), 'IsMSShipped') = 0
)
WHILE (#TableName IS NOT NULL)
AND (#ColumnName IS NOT NULL)
BEGIN
SET #ColumnName = (
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(#TableName, 2)
AND TABLE_NAME = PARSENAME(#TableName, 1)
AND DATA_TYPE IN (
'char'
,'varchar'
,'nchar'
,'nvarchar'
)
AND QUOTENAME(COLUMN_NAME) > #ColumnName
)
IF #ColumnName IS NOT NULL
BEGIN
INSERT INTO #Results
EXEC (
'SELECT ''' + #TableName + '.' + #ColumnName + ''', LEFT(' + #ColumnName + ', 3630)
FROM ' + #TableName + ' (NOLOCK) ' + ' WHERE ' + #ColumnName + ' LIKE ' + #SearchStr2
)
END
END
END
SELECT ColumnName, ColumnValue FROM #Results
END

You need to write a stored procedure to scan through all the tables.
The script below gives to the tables and columns. From this you should create a SQL in-flight and execute dynamically to SELECT from tables. Let us know if you need more details.
SELECT tb.name AS table_name,
c.name AS column_name,
c.column_id,
tp.name AS column_data_type,
c.max_length,
c.precision,
c.scale,
CASE c.is_nullable WHEN 1 THEN 'YES' ELSE 'NO' END AS is_nullable
FROM sys.tables tb,
sys.columns c,
sys.types tp
WHERE tb.object_id = c.object_id
AND SCHEMA_NAME(tb.schema_id) = 'dbo'
AND c.user_type_id = tp.user_type_id
ORDER BY table_name, column_id;
