Question

I want to generate a script of all the indexes in a database(Create Index).

I don’t want the index script along with create table script. how can we generate it in SQL Server (2005 or 2008). There needs to be separate script for Clustered and Non Clustered Indexes.

This is an excellent article on SQL Server Central that I’ve used.

Here is another that you might like better.

If it’s not exactly what you’re looking for (sorting, filtering) I’m sure it would be easier to edit these than to start from scratch.

Here’s the slightly corrected (2019) code from the first example:

-- Get all existing indexes, but NOT the primary keys
DECLARE cIX CURSOR FOR
    SELECT OBJECT_NAME(SI.Object_ID), SI.Object_ID, SI.Name, SI.Index_ID
        FROM Sys.Indexes SI 
            LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS TC ON SI.Name = TC.CONSTRAINT_NAME AND OBJECT_NAME(SI.Object_ID) = TC.TABLE_NAME
        WHERE TC.CONSTRAINT_NAME IS NULL
            AND OBJECTPROPERTY(SI.Object_ID, 'IsUserTable') = 1
        ORDER BY OBJECT_NAME(SI.Object_ID), SI.Index_ID

DECLARE @IxTable SYSNAME
DECLARE @IxTableID INT
DECLARE @IxName SYSNAME
DECLARE @IxID INT

-- Loop through all indexes
OPEN cIX
FETCH NEXT FROM cIX INTO @IxTable, @IxTableID, @IxName, @IxID
WHILE (@@FETCH_STATUS = 0)
BEGIN
    DECLARE @IXSQL NVARCHAR(4000) SET @IXSQL = ''
    SET @IXSQL = 'CREATE '

    -- Check if the index is unique
    IF (INDEXPROPERTY(@IxTableID, @IxName, 'IsUnique') = 1)
        SET @IXSQL = @IXSQL + 'UNIQUE '
    -- Check if the index is clustered
    IF (INDEXPROPERTY(@IxTableID, @IxName, 'IsClustered') = 1)
        SET @IXSQL = @IXSQL + 'CLUSTERED '

    SET @IXSQL = @IXSQL + 'INDEX ' + @IxName + ' ON ' + @IxTable + '('

    -- Get all columns of the index
    DECLARE cIxColumn CURSOR FOR 
        SELECT SC.Name
        FROM Sys.Index_Columns IC
            JOIN Sys.Columns SC ON IC.Object_ID = SC.Object_ID AND IC.Column_ID = SC.Column_ID
        WHERE IC.Object_ID = @IxTableID AND Index_ID = @IxID
        ORDER BY IC.Index_Column_ID

    DECLARE @IxColumn SYSNAME
    DECLARE @IxFirstColumn BIT SET @IxFirstColumn = 1

    -- Loop throug all columns of the index and append them to the CREATE statement
    OPEN cIxColumn
    FETCH NEXT FROM cIxColumn INTO @IxColumn
    WHILE (@@FETCH_STATUS = 0)
    BEGIN
        IF (@IxFirstColumn = 1)
            SET @IxFirstColumn = 0
        ELSE
            SET @IXSQL = @IXSQL + ', '

        SET @IXSQL = @IXSQL + @IxColumn

        FETCH NEXT FROM cIxColumn INTO @IxColumn
    END
    CLOSE cIxColumn
    DEALLOCATE cIxColumn

    SET @IXSQL = @IXSQL + ')'
    -- Print out the CREATE statement for the index
    IF @IXSQL != '' BEGIN PRINT @IXSQL END

    FETCH NEXT FROM cIX INTO @IxTable, @IxTableID, @IxName, @IxID
END

CLOSE cIX
DEALLOCATE cIX
