You are supposed to put your SQL code in the "What I have tried" field. Use Improve question to do that.

SQL Pivot is what you need.

This is not informative, state in what the result is not what you want.
Show query, and actual result.

I am assuming the following table structure (in particular that column paramvalue >= 0)
and providing the following query:
Table:

SQL

<pre>
create table companyvalues
(
companyid           varchar(5),
paramkey            varchar(30),
paramvalue          integer,
constraint pk_companyvalues primary key(companyid, paramkey),
constraint ck_paramvalue check(paramvalue >= 0)
);

with companynames as
(
select distinct companyid compid
from companyvalues
) ,
details as
(
select * from companyvalues
) 
select compid, max(MinLength) MinLength, max(MaxLength) MaxLength, max(IsAlphanumeric) IsAlphanumeric, 
max(IsCaseSensitive) IsCaseSensitive, max(IsSpecialChars) IsSpecialChars, max(PasswordExpiryDays) PasswordExpiryDays,
max(AlertDays) AlertDays
from
(
select compid 
		, case when  paramkey = 'MinLength'          then paramvalue else -1 end  MinLength         	
		, case when  paramkey = 'MaxLength'          then paramvalue else -1 end  MaxLength         	
		, case when  paramkey = 'IsAlphanumeric'     then paramvalue else -1 end  IsAlphanumeric    
		, case when  paramkey = 'IsCaseSensitive'    then paramvalue else -1 end  IsCaseSensitive   
		, case when  paramkey = 'IsSpecialChars'     then paramvalue else -1 end  IsSpecialChars    
		, case when  paramkey = 'PasswordExpiryDays' then paramvalue else -1 end  PasswordExpiryDays
		, case when  paramkey = 'AlertDays'          then paramvalue else -1 end  AlertDays         
from companynames, details
where compid = companyid
) finalresult
group by compid
order by 1

Did you really try using PIVOT? Here is a working example.

SQL

DECLARE @cp2 TABLE (
Companyid	VARCHAR(50),
ParamKey	VARCHAR(50),
ParamValue	INT
)

INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'MinLength', 8)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'MaxLength', 0)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'IsAlphanumeric', 1)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'IsCaseSensitive', 0)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'IsSpecialChars', 0)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'PasswordExpiryDays', 80)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'ABC', N'AlertDays', 10)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'MinLength', 7)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'MaxLength', 1)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'IsAlphanumeric', 3)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'IsCaseSensitive', 1)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'IsSpecialChars', 1)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'PasswordExpiryDays', 90)
INSERT @cp2 ([CompanyId], [ParamKey], [ParamValue]) VALUES (N'XYZ', N'AlertDays', 5)

SELECT Companyid, MinLength, [MaxLength], IsAlphanumeric, IsCaseSensitive, IsSpecialChars,
PasswordExpiryDays,AlertDays
FROM (
SELECT Companyid, ParamKey, ParamValue
FROM @cp2) up
PIVOT (MAX(ParamValue) FOR ParamKey IN (MinLength, [MaxLength], IsAlphanumeric, IsCaseSensitive, IsSpecialChars,
PasswordExpiryDays,AlertDays)) AS pvt
ORDER BY Companyid
GO

Output:

Companyid	MinLength	MaxLength	IsAlphanumeric	IsCaseSensitive	IsSpecialChars	PasswordExpiryDays	AlertDays
ABC	8	0	1	0	0	80	10
XYZ	7	1	3	1	1	90	5
