Generate insert from a table

Exemple:

EXECUTE dbo.GenerateInsert @ObjectName = N'dbo.tableName';

Procedure:


IF EXISTS (SELECT 1 FROM sys.objects WHERE object_id = OBJECT_ID(N'dbo.GenerateInsert') AND type in (N'P', N'PC'))
  DROP PROCEDURE dbo.GenerateInsert;
GO

/*******************************************************************************
Procedure: GenerateInsert (Build 6)
Decription: Generates INSERT statement(s) for data in a table.
Purpose: To regenerate data at another location.
  To script data populated in automated way.
  To script setup data populated in automated/manual way.
Project page: http://github.com/drumsta/sql-generate-insert

Arguments:
  @ObjectName nvarchar(261)
    Format: [schema_name.]object_name
    Specifies the name of a table or view to generate the INSERT statement(s) for
  @TargetObjectName nvarchar(261) = NULL
    Specifies the name of target table or view to insert into
  @OmmitInsertColumnList bit = 0
    When 0 then syntax is like INSERT INTO object (column_list)...
    When 1 then syntax is like INSERT INTO object...
  @GenerateSingleInsertPerRow bit = 0
    When 0 then only one INSERT statement is generated for all rows
    When 1 then separate INSERT statement is generated for every row
  @UseSelectSyntax bit = 0
    When 0 then syntax is like INSERT INTO object (column_list) VALUES(...)
    When 1 then syntax is like INSERT INTO object (column_list) SELECT...
  @UseColumnAliasInSelect bit = 0
    Has effect only when @UseSelectSyntax = 1
    When 0 then syntax is like SELECT 'value1','value2'
    When 1 then syntax is like SELECT 'value1' column1,'value2' column2
  @FormatCode bit = 1
    When 0 then no Line Feeds are generated
    When 1 then additional Line Feeds are generated for better readibility
  @GenerateOneColumnPerLine bit = 0
    When 0 then syntax is like SELECT 'value1','value2'...
      or VALUES('value1','value2')...
    When 1 then syntax is like
         SELECT
         'value1'
         ,'value2'
         ...
      or VALUES(
         'value1'
         ,'value2'
         )...
  @GenerateGo bit = 0
    When 0 then no GO commands are generated
    When 1 then GO commands are generated after each INSERT
  @PrintGeneratedCode bit = 1
    When 0 then generated code will be printed using PRINT command
    When 1 then generated code will be selected using SELECT statement 
  @TopExpression nvarchar(max) = NULL
    When supplied then INSERT statements are generated only for TOP rows
    Format: (expression) [PERCENT]
    Example: @TopExpression='(5)' is equivalent to SELECT TOP (5)
    Example: @TopExpression='(50) PERCENT' is equivalent to SELECT TOP (5) PERCENT
  @FunctionParameters nvarchar(max) = NULL
    When @ObjectName is type of Table-Valued User-Defined function or Inline User-Defined function
      then @FunctionParameters should be supplied to pass to function.
    One or more parameters can be specified.
    Example: @FunctionParameters='(1)' is equivalent to SELECT * FROMN ObjectName(1)
  @SearchCondition nvarchar(max) = NULL
    When supplied then specifies the search condition for the rows returned by the query
    Format: <search_condition>
    Example: @SearchCondition='column1 != ''test''' is equivalent to WHERE column1 != 'test'
  @OrderByExpression nvarchar(max) = NULL
    When supplied then sorts data returned by a query. The parameter doesn't apply to the ranking function like ROW_NUMBER, RANK, DENSE_RANK, and NTILE.
    Format: <order_by_expression>
    Example: @OrderByExpression='DATEPART(year, HireDate) DESC, LastName DESC COLLATE Latin1_General_CS_AS'
  @OmmitUnsupportedDataTypes bit = 1
    When 0 then error is raised on unsupported data types
    When 1 then columns with unsupported data types are excluded from generation process
  @PopulateIdentityColumn bit = 1
    When 0 then identity columns are excluded from generation process
    When 1 then identity column values are preserved on insertion
  @PopulateTimestampColumn bit = 0
    When 0 then rowversion/timestamp column is inserted using DEFAULT value
    When 1 then rowversion/timestamp column values are preserved on insertion,
      useful when restoring into archive table as varbinary(8) to preserve history
  @PopulateComputedColumn bit = 0
    When 0 then computed columns are excluded from generation process
    When 1 then computed column values are preserved on insertion,
      useful when restoring into archive table as scalar values to preserve history
  @GenerateProjectInfo bit = 1
    When 0 then no spam is generated at all.
    When 1 then short comments are generated, i.e. SP build number and project page.
  @GenerateSetNoCount bit = 1
    When 0 then no SET NOCOUNT ON is generated at the beginning.
    When 1 then SET NOCOUNT ON is generated at the beginning.
  @GenerateStatementTerminator bit = 1
    When 0 then each statement is not separated by semicolon (;).
    When 1 then semicolon (;) is generated at the end of each statement.
  @ShowWarnings bit = 1
    When 0 then no warnings are printed.
    When 1 then warnings are printed if columns with unsupported data types
      have been excluded from generation process
    Has effect only when @OmmitUnsupportedDataTypes = 1
  @Debug bit = 0
    When 0 then no debug information are printed.
    When 1 then constructed SQL statements are printed for later examination
