I have got a ms SQL relation database. There is one complex search query with around 30 joins and self joins. It has around 21 where clauses. I am looking for ways to speed up this query. You can add more index to database or restructure this query. I will provide you with copy of database. I can see the query only has a where clause filtering on a name (company name I think). Leaving the search fairly open ended like this can sometimes cause longer response times, compared to filtering by a specific client, sample number, job, date range etc. Also this is a free text field (which requires a number of joins) which probably contributes to the longer time.

I’m an acknowledged expert in sql server. Ex Microsoft MVP. See my web site www.nigelrivett.net. Would need to know how the query works, can it be put in a stored procedure or split into multiple queries. Which version sql server as that makes a difference to what’s available e.g. column store indexes. Can the database be restructured or adductor ion always redundant tables added? Anyway I’m sure I could help.

Dear Sir/Madam, I have relational database design and development experience of 10 years. Several months ago I worked on the performance issue of an HR database where the query included searching a large free-text field. The duration of the query was 20 minutes. After I completed my work the query completed only in 20 seconds. The employer and I have been working since then. I would like to improve the performance of your query. Hope to hear from you soon. Best Regards Huseyin Aygun
