Insert script for a particular set of rows in SQL - sql-server

Question

I am using SQL Server 2008. I use to take the script of my data from SQL table using Tasks --> Generate Scripts option.
Here is my problem:
Let's say I have 21,000 records in Employee table. When I take the script of this table, it takes the insert script for all 21000 records. What is the solution if I want to take only the script of 18000 records from the table?
Is there any solution using SQL query or from the tasks wizard?
Thanks in advance...

Answer 1

Create a new View where you select your desired rows from your Employee table e.g. SELECT TOP 21000...
Then simply script that View instead of the Table.

Answer 2

In case the views are not an option for you I wrote the following code based on the Aaron Bertrand's answer here that will give the insert statement for a single record in the db.
CREATE PROCEDURE dbo.GenerateSingleInsert
#table NVARCHAR(511), -- expects schema.table notation
#pk_column SYSNAME, -- column that is primary key
#pk_value NVARCHAR(10) -- change data type accordingly
AS
BEGIN
SET NOCOUNT ON;
DECLARE #cols NVARCHAR(MAX), #vals NVARCHAR(MAX),
#valOut NVARCHAR(MAX), #valSQL NVARCHAR(MAX);
SELECT #cols = N'', #vals = N'';
SELECT #cols = #cols + ',' + QUOTENAME(name),
#vals = #vals + ' + '','' + ' + 'ISNULL('+REPLICATE(CHAR(39),4)+'+RTRIM(' +
CASE WHEN system_type_id IN (40,41,42,43,58,61) -- dateteime and time stamp type
THEN
'CONVERT(CHAR(8), ' + QUOTENAME(name) + ', 112) + '' ''+ CONVERT(CHAR(14), ' + QUOTENAME(name) + ', 14)'
WHEN system_type_id IN (35) -- text type
THEN
'REPLACE(CAST(' + QUOTENAME(name) + 'as nvarchar(MAX)),'+REPLICATE(CHAR(39),4)+','+REPLICATE(CHAR(39),6)+')'
ELSE
'REPLACE(' + QUOTENAME(name) + ','+REPLICATE(CHAR(39),4)+','+REPLICATE(CHAR(39),6)+')'
END
+ ')+' + REPLICATE(CHAR(39),4) + ',''null'') + '
FROM sys.columns WHERE [object_id] = OBJECT_ID(#table)
AND system_type_id <> 189 -- can't insert rowversion
AND is_computed = 0; -- can't insert computed columns
SELECT #cols = STUFF(#cols, 1, 1, ''),
#vals = REPLICATE(CHAR(39),2) + STUFF(#vals, 1, 6, '') + REPLICATE(CHAR(39),2) ;
SELECT #valSQL = N'SELECT #valOut = ' + #vals + ' FROM ' + #table + ' WHERE '
+ QUOTENAME(#pk_column) + ' = ''' + RTRIM(#pk_value) + ''';';
EXEC sp_executesql #valSQL, N'#valOut NVARCHAR(MAX) OUTPUT', #valOut OUTPUT;
SELECT SQL = 'INSERT ' + #table + '(' + #cols + ') SELECT ' + #valOut;
END
I took the above code and wrapped it the following proc that will use the where clause you give it to select which insert statements to create
CREATE PROCEDURE dbo.GenerateInserts
#table NVARCHAR(511), -- expects schema.table notation
#pk_column SYSNAME, -- column that is primary key
#whereClause NVARCHAR(500) -- the where clause used to parse down the data
AS
BEGIN
declare #temp TABLE ( keyValue nvarchar(10), Pos int );
declare #result TABLE ( insertString nvarchar(MAX) );
declare #query NVARCHAR(MAX)
set #query =
'with qry as
(
SELECT ' + #pk_column + ' as KeyValue, ROW_NUMBER() over(ORDER BY ' + #pk_column + ') Pos
from ' + #table + '
' + #whereClause + '
)
select * from qry'
insert into #temp
exec sp_sqlexec #query
Declare #i int, #key nvarchar(10)
select #i = count(*) from #temp
WHILE #i > 0 BEGIN
select #key = KeyValue from #temp where Pos = #i
insert into #result
exec [dbo].[GenerateSingleInsert] #table, #pk_column, #key
set #i = #i - 1
END
select insertString from #result
END
Calling it could look like the following. You pass in the table name, the table primary key and the where clause and you should end up with your insert statements.
set #whereClause = 'where PrettyColorsId > 1000 and PrettyColorsID < 5000'
exec [dbo].GenerateInserts 'dbo.PrettyColors', 'PrettyColorsID', #whereClause
set #whereClause = 'where Color in (' + #SomeValues + ')'
exec [dbo].GenerateInserts 'dbo.PrettyColors', 'PrettyColorsID', #whereClause
