Stored procedure to generate INSERT..VALUES statements in SQL Server.

Image 1


The stored procedure InsertGenerator generates the INSERT..VALUES statements for the specified table name.


SQL Server doesn’t allow generation of INSERT statements for the table data, when Generate SQL Script option is selected. The workaround is to make use of DTS for transferring data across servers. However, there exists a need to generate INSERT statements from the tables for porting data. Simplest example is when small or large amount of data needs to be taken out on a removable storage media and copied to a remote location, INSERT..VALUES statements come handy.

Using the code

This small yet useful stored procedure will take as parameter the table name and generates the INSERT SQL statements for the same. The output can be redirected to either text format (Ctrl+T in Query Analyzer) or Output to a text file. The procedure accepts an input varchar type parameter that has to be the table name under consideration for statement generation.

CREATE PROC InsertGenerator
(@tableName varchar(100)) as

Then it includes a cursor to fetch column specific information (column name and the data type thereof) from information_schema.columns pseudo entity and loop through for building the INSERT and VALUES clauses of an INSERT DML statement.

--Declare a cursor to retrieve column specific information 
--for the specified table
SELECT column_name,data_type FROM information_schema.columns 
    WHERE table_name = @tableName
OPEN cursCol
DECLARE @string nvarchar(3000) --for storing the first half 
                               --of INSERT statement
DECLARE @stringData nvarchar(3000) --for storing the data 
                                   --(VALUES) related statement
DECLARE @dataType nvarchar(1000) --data types returned 
                                 --for respective columns
SET @string='INSERT '+@tableName+'('
SET @stringData=''

DECLARE @colName nvarchar(50)

FETCH NEXT FROM cursCol INTO @colName,@dataType

IF @@fetch_status<>0
    print 'Table '+@tableName+' not found, processing skipped.'
    close curscol
    deallocate curscol

IF @dataType in ('varchar','char','nchar','nvarchar')
    SET @stringData=@stringData+'''''''''+
if @dataType in ('text','ntext') --if the datatype 
                                 --is text or something else 
    SET @stringData=@stringData+'''''''''+
          isnull(cast('+@colName+' as varchar(2000)),'''')+'''''',''+'
IF @dataType = 'money' --because money doesn't get converted 
                       --from varchar implicitly
    SET @stringData=@stringData+'''convert(money,''''''+
        isnull(cast('+@colName+' as varchar(200)),''0.0000'')+''''''),''+'
IF @dataType='datetime'
    SET @stringData=@stringData+'''convert(datetime,''''''+
        isnull(cast('+@colName+' as varchar(200)),''0'')+''''''),''+'
IF @dataType='image' 
    SET @stringData=@stringData+'''''''''+
       as varchar(6)),''0'')+'''''',''+'
ELSE --presuming the data type is int,bit,numeric,decimal 
    SET @stringData=@stringData+'''''''''+
          isnull(cast('+@colName+' as varchar(200)),''0'')+'''''',''+'

SET @string=@string+@colName+','

FETCH NEXT FROM cursCol INTO @colName,@dataType

After both of the clauses are built, the VALUES clause contains a trailing comma which needs to be replaced with a single quote. The prefixed clause will only face removal of the trailing comma.

DECLARE @Query nvarchar(4000) -- provide for the whole query, 
                              -- you may increase the size

SET @query ='SELECT '''+substring(@string,0,len(@string)) + ') 
    VALUES(''+ ' + substring(@stringData,0,len(@stringData)-2)+'''+'')'' 
    FROM '+@tableName
exec sp_executesql @query --load and run the built query

Eventually, close and de-allocate the cursor created for columns information.

CLOSE cursCol

After the procedure is compiled and created, just run it in Query Analyzer by using the following syntax:

InsertGenerator <tablename>


USE pubs
InsertGenerator employee 

Then copy the INSERT statements and run’em in the query analyzer.

Before the INSERTs are run, SET IDENTITY_INSERT <TABLENAME>ON should be passed for adding values in an identity-based column.

Points of Interest

D: T-SQL lovers might wish to extend this procedure for providing support for binary data types such as IMAGE etc.
