我们的数据导入和导出比大多数 Sql 和数据库工具快 100 万倍。比方说,我在 DataGrip 中 15 秒内导入了超过 20 万行,而在 MySQL Workbench 中导入这些行需要 15 年! Fergus Bray Elliott 全栈开发者 我必须承认,JetBrains DataGrip 已经在我的心里种草了!UI/UX 与过去笨重的 SQL 工具截然不同。作为 JetBrain...

If the number does not have a decimal position (like an integer number), then SQL Server will add implicitly .00 to the number. For Example, 123 will become 123.00 Maximum Limit The precision and scale determine the maximum limit that you can store in decimal data type....

The float data type takes an optional parameter of the number of digits stored after the decimal called the mantissa. If the mantissa is defined between 1 and 24, then a float will consume 4 bytes of storage. If the mantissa is defined between 25 and 53, then a float will consume 8 ...
