Answer : How to rotate rows into columns in a table using T-SQL

try:

create table #test (fieldname varchar(100), datatype varchar(100), length varchar(50))

insert into #test
(fieldname,datatype,length)
select 'field1',                 'nvarchar',           '60'
union all
select 'field2',                 'nvarchar',           '60'
union all
select 'field3',                 'int',                    '4'
union all
select 'field4',                 'datetime',           '8'

declare @SQLStatement      nvarchar(2000),
        @ColumnDefinition nvarchar(1000),
        @TableName        nvarchar(50)

set @TableName = 'ThisIsMyTableName'

select @SQLStatement = 'CREATE TABLE ' + @TableName + ' (**COLUMNDEFINITION**)'

select @ColumnDefinition = COALESCE(@ColumnDefinition + ',','')
       + FieldName
       + ' '
       + DataType
       + CASE
           WHEN DataType in ('VARCHAR','NVARCHAR','CHAR','NCHAR','FLOAT') -- THIS CAN BE ALTERED TO SUIT YOUR NEEDS
            AND Length IS NOT NULL THEN '(' + Length + ')'
           ELSE ''
         END
  FROM #TEST

drop table #test

SET @SQLStatement = REPLACE(@SQLStatement,'**COLUMNDEFINITION**',@ColumnDefinition)

EXEC(@SQLStatement)
