Generate script of All the indexes in a database


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.


Solution

  • 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
