£10-15 GBP / hour

I have a SQL Azure database that requires an expert to help optimise some queries. That's about it. By the hour, and ad hoc stuff guys and gals. Some tables with hundreds of millions of rows, but some queries are chugging along and I need some help from a SQL Server wizard.

Hi I am a database expert with 15 years experience in handling MS SQL databases. I have worked as DBA for large ERP databases and use to write and do performance tuning for SQL queries, procedures and triggers. I have worked from SQL 2000 to SQL 2014. But do not have an extensive experience with Azure, but that should not be a problem when it comes to query optimization. Look forward to hear from you. Thanks Roni

Hi, I've never used Azure, but I have lots of experience with MySQL. SQL is the same with any DB you choose those (SQL databases of course) - there's usually only one or two additional functions available depending on the variant you use. Anyway, if your queries are slow then it could be due bad indexing, or just having a table joined with the result of a query (which leads to massive slow down because all indexing is lost in the sub-query). Depending on the structure of the data and primary keys you can sometimes horizontally partition your table - so if you know a priori that the data you need is held within a certain range of primary keys (e.g. corresponding to a particular year) then you don't have to query the whole data, only the relevant partition. By the way I'm also in the same time-zone as you so shouldn't be hard to get a hold of if you need help working out a query. Thanks a lot, John
