Finding Indexes For A Table in Sybase

sybase list columns in table

I am currently working in an environment where I am made double blind.

  1. I have to email any queries I need to run to a employee of the client
  2. That employee runs them in a SAS client, with an odbc connection to SyBase

I need to find out how to ascertain exactly what indexes exist on a specific table. I would use sp_helpindex, but apparently it doesn't exist on their instance of SyBase.

We believe that it is SyBase 12, but again I can't be certain of anything.

Does anyone have SQL for... - Confirming exactly what version of SyBase we're working on? - The details of all indexes that exist for a given table?

To "Confirming exactly what version of SyBase we're working on?"

Why not use:

select @@version

Sybase website is down (at least here), but it would be something like:




where indexset is tablename because every table has a indexset assigned with the same name.

If you have access to sybase website possibly you can go further :)

Most Sybase products have a -v command line argument to tell the version with or without the engine running.

To find the indexes on any table enter the following, where my_table is your table's name:

from sysindexes i, sysobjects o
where = 'my_table'
  and =

sp_helpindex, Reports information about the indexes created on a table. Syntax. sp_helpindex objname. Parameters. objname. is the name of a table in the current database. Indexes also improve performance dramatically when joining tables. When executing a query, SQL Anywhere chooses how to access each table. When the database server cannot find a suitable index, it resorts to scanning the table sequentially—a process that can take a long time.

You can use this query:

from sysindexes i, sysobjects o
where = 'table_name' and i.indid >=1
and =

Using system tables to identify the columns of a table index in Sybase, I came up with the following solution - thanks to the comment by Phil: SELECT distinct as index_name, index_col(, i.indid, c.colid) as name FROM� In other words, a nonclustered index has an extra level between the index structure and the data itself. Each of the up to 249 nonclustered indexes permitted on a table can provide access to the data in a different sorted order. Finding data using a clustered index is almost always faster than using a nonclustered index.

Find Indexes on multiple tables, not like image indexes

select name =,iname = from sysindexes i, sysobjects o where in ('table1','table2','table3') and not like 't%' and i.indid >=1 and =

Sybase: Find all tables in a database with a unique index , The following statement will return a list of all user tables in the current database which have a unique index: SELECT FROM� Types of indexes. Adaptive Server provides two types of indexes: Clustered indexes, where the table data is physically stored in the order of the keys on the index: For allpages-locked tables, rows are stored in key order on pages, and pages are linked in key order.

For sybase version:

select @@version

in Sybase version SAP IQ/16, you can get list of indexes with following (table name my_table is case sensitive:

select *
from sys.sysindexes
where tname = 'my_table';

Sybase Admin, To return only system tables, replace "'TABLE'" with "'SYSTEM TABLE'". Owners. This is a query to get all Sybase owners. select name from dbo.sysusers where� Find Indexes on a Table Using SP_HELPINDEX sp_helpindex is a system stored procedure which lists the information of all the indexes on a table or view. This is the easiest method to find the indexes in a table. sp_helpindex returns the name of the index, description of the index and the name of the column on which the index was created.

Sybase Index Options, If not selected, a non-unique index is created where table rows can have duplicate Type: Sybase IQ uses HG or LF indexes to generate better or faster query� The default is nonunique. To create a nonunique clustered index on a table that contains duplicate rows, specify allow_dup_row or ignore_dup_row. See “Duplicate rows”. When you create a unique local index on range-, list-, and hash-partitioned tables, the index key list is a superset of the partition-key list. clustered

Caution. In order to list all the tables and rows count, the following query can be used. select convert (varchar (30), AS table_name, row_count (db_id (), AS row_count from sysobjects o where type = 'U' order by table_name In order get a list of tables which has the table name like, use the following query.

  • Thanks for this, though it appears that it's failing due to other system SPs being missing. I guess my client would prefer me to simply use the Force :)
  • @Dems yep it's what I though it would happen ^^ But do you know which version is?
  • Nearly 5 hours to find out, but I got it! Sybase IQ/12.7.0/100114/P/ESD 9/Enterprise Linux64 - amd64,Opteron64,X86_64/2.4.21-27.0.1.ELsmp/64bit/2010-01-14 10:20:04
  • @Dems check my update, it woulb be something like that I presume.
