1- Explanation of Scripts
A)Syntax for inserting data in table is as below
Insert into table(col1,col2,col3,col4,col5)
-- To achieve this part i
--have used below variable
------@CSV_COLUMN-------
values(Col1 data in quote, Col2..quote,..Col5..quote)
-- To achieve this part
-- i.e column data in
--quote i have used
--below variable
----@QUOTED_DATA---
C)To get above data from existing
table we have to write the select
query in such way that the output
will be in form of as above scripts
D)Then Finally i have Concatenated
above variable to create
final script that's will
generate insert script on execution
E)
@TEXT='SELECT ''INSERT INTO
'+@TABLE_NAME+'('+@CSV_COLUMN+')VALUES('''+'+'+SUBSTRING(@QUOTED_DATA,1,LEN(@QUOTED_DATA)-5)+'+'+''')'''+' Insert_Scripts FROM '+@TABLE_NAME + @FILTER_CONDITION
F)And Finally Executed the above query EXECUTE(TEXT)
G)QUOTENAME() function is used to wrap
column data inside quote
H)ISNULL is used because if any row has NULL
data for any column the query fails
and return NULL thats why to avoid
that i have used ISNULL
I)And created the sp sp_generate_insertscripts
for same
1- Just put the table name for which you want insert script
2- Filter condition if you want specific results
----------Final Procedure To generate Script------
CREATE PROCEDURE sp_generate_insertscripts
(
@TABLE_NAME VARCHAR(MAX),
@FILTER_CONDITION VARCHAR(MAX)=''
)
AS
BEGIN
SET NOCOUNT ON
DECLARE @CSV_COLUMN VARCHAR(MAX),
@QUOTED_DATA VARCHAR(MAX),
@TEXT VARCHAR(MAX)
SELECT @CSV_COLUMN=STUFF
(
(
SELECT ',['+ NAME +']' FROM sys.all_columns
WHERE OBJECT_ID=OBJECT_ID(@TABLE_NAME) AND
is_identity!=1 FOR XML PATH('')
),1,1,''
)
SELECT @QUOTED_DATA=STUFF
(
(
SELECT ' ISNULL(QUOTENAME('+NAME+','+QUOTENAME('''','''''')+'),'+'''NULL'''+')+'','''+'+' FROM sys.all_columns
WHERE OBJECT_ID=OBJECT_ID(@TABLE_NAME) AND
is_identity!=1 FOR XML PATH('')
),1,1,''
)
SELECT @TEXT='SELECT ''INSERT INTO '+@TABLE_NAME+'('+@CSV_COLUMN+')VALUES('''+'+'+SUBSTRING(@QUOTED_DATA,1,LEN(@QUOTED_DATA)-5)+'+'+''')'''+' Insert_Scripts FROM '+@TABLE_NAME + @FILTER_CONDITION
--SELECT @CSV_COLUMN AS CSV_COLUMN,@QUOTED_DATA AS QUOTED_DATA,@TEXT TEXT
EXECUTE (@TEXT)
SET NOCOUNT OFF
END
