mssql running queries

1. MSSQL Memory ArchitectureCompared to the Oracle,mssql memory area is not so clear, but similar to Oracle, the MSSQL memory area can be broadly divided into three parts: buffer pool,query/workspace memories, other cache/memory. Let's take a brief

Hacking MSSQL without knowing the password Copyright owned by original author0x01 Preface In a recent penetration test, I accidentally noticed some unencrypted MSSQL traffic during packet capture. Because the syntax is put there, it won't be wrong.

A service is an application running in the system background. Services generally provide some core operating system functions. MSSQL provides the following services. Service type service description SQLServer provides data storage, processing, and

There are many reasons for slow query speed. The following are common causes:1. No index or no index is used (this is the most common problem of slow queryProgramDesign defects)2. Low I/O throughput, resulting in a bottleneck effect.3. the query is

How can I speed up queries?1. upgrade hardware2. Create an index based on the query conditions, optimize the index, optimize the access mode, and limit the data volume of the result set.3. Expand the server memory4. Increase the number of server
