Problem: sqlc can't recognize PostgreSQL data types numeric and decimal with the default database driver package database/sql, it makes them string. Using the PostgreSQL driver pgx, Sqlc can make them pgtype.Numeric type, but still can't overrides them to float64: ...
In Microsoft SQL Server (MSSQL), the DECIMAL, FLOAT, and NUMERIC data types are used to store numerical values, but they have differences in terms of precision, storage, and behavior. Here's a comparison of these data types in MSSQL: 1. DECIMAL DECIMAL is used to store exact decimal nu...

c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///< 2个参数printf("%d, %d", a, b);///< 3个参数 测...
