But the simple things in design are easily forgotten by people, as follows a simple but very loose list query. --CREATE TABLE KeyValue --( --[key] NVARCHAR (), --[value] NVARCHAR --) CREATE TABLETablen

Multi-condition dynamic query of LINQ to SQL is indeed a headache. A lot of data needs to be written in the expression tree or reflection method.CodeSometimes it is better to think about this complexity than to go back to the era of manual SQL concatenation. However, technology is always moving forward, and it is still

Therefore, queries must be completed quickly and easily. However, most databases need to process multiple queries at the same time. These queries will n
