combine multiple rows into a single row with repeating set of columns - sql

Question

I have a table with multiple insurance policies per client. One Policy per record.
I need to represent all the policies in one row per client.
I have read all the similar questions and they may be close but I don't seem to be able to translate the answers into my situation.
The table that I have looks like this
enter code here Client-ID Ins-Company Policy-Number Start-Date
1 BCBS BSBC1 2018-01-01
1 Aetna Aetna1 2017-01-01
1 Self-Pay N/A 2016-01-01
2 Self-Pay N/A 2015-01-01
3 BCBS BCBS3 2014-01-01
3 Self-Pay N/A 2013-01-01
Expected Result:
enter code here Client-ID Ins-Co1 Policy1 Start1 Ins-Co2 Policy2 Start2 Ins-Co3 Policy3 Start3
1 BCBS BCBS1 2018-01-01 Aetna Aetna1 2017-01-01 Self-Pay N/A 2016-01-01
2 Self-Pay N/A 2015-01-01
3 BCBS BCBS3 2014-01-01 Self-Pay N/A 2013-01-01
In need to create another table with these records

Answer 1

I created the result I needed with the following code.
First, I created a View of the source table that added a Row Number using the following Function:
ROW_NUMBER() OVER(PARTITION BY a.Client_ID ORDER BY a.Billing_Order ASC) AS Row_No
and built the following Code
enter code hereDECLARE #sql varchar(max)
DECLARE #colList varchar(max)
--create dynamic list of columns
SELECT #colList =
STUFF
(
(
SELECT + ',' +
quotename(colName + Row_No)
FROM Credible_Client_Insurance_Raw_Data_Query
CROSS APPLY
(
SELECT 1 As Ord, 'Payer_ID' ColName UNION ALL
SELECT 2 As Ord, 'Billing_Order' UNION ALL
SELECT 3 As Ord, 'Insurance_ID' UNION ALL
SELECT 4 As Ord, 'Group_No' UNION ALL
SELECT 5 As Ord, 'Copay_Fee' UNION ALL
SELECT 6 As Ord, 'Start_Date'
) v
GROUP BY colName, Ord, Row_No
ORDER BY Row_No, Ord
for xml path(''), type
).value('/','varchar(max)'),1,1,''
)
--unpivot columns into rows and then apply pivot
SET #sql
= '
SELECT Client_ID, ' + #colList + '
FROM
(
SELECT Client_ID, ColVal,
colName + Row_No ColName
FROM Credible_Client_Insurance_Raw_Data_Query
CROSS APPLY
(
SELECT Payer_ID As ColVal, ''Payer_ID'' ColName UNION ALL
SELECT Billing_Order, ''Billing_Order'' UNION ALL
SELECT Insurance_ID, ''Insurance_ID'' UNION ALL
SELECT Group_No, ''Group_No'' UNION ALL
SELECT CAST(Copay_Fee AS VARCHAR), ''Copay_Fee'' UNION ALL
SELECT CAST(Start_Date AS VARCHAR), ''Start_Date''
) v
) A
PIVOT
(
MAX(ColVal) FOR ColName IN (' + #colList + ')
) P1 '
EXEC(#sql)
Code was copied from another question
Pivot on multiple columns based on single column
Now I have a follow up question:
Now that I created a query that provides the result I need
I need to place the result into a table.
I cannot take this query and make it into a VIEW because it starts with a Declare Statement ( Illegal for Views )
So how do I transfer this query data into a Table?
